Essential Guide to Waterline Replacement for Homeowners

Essential Guide to Waterline Replacement for Homeowners: Costs, Methods, Signs, and Materials

Waterline replacement means removing and replacing the underground service piping that delivers treated water from the municipal main or meter to a home’s internal plumbing, and timely replacement prevents property damage, water contamination, and escalating repair costs. This guide explains why main water line replacement matters, how homeowners recognize failing lines, what replacement methods exist (trenched vs trenchless), which pipe materials perform best, and how costs typically break down. Recognizing early warning signs such as low water pressure, discolored water, soggy patches in the yard, or unexplained bill spikes lets homeowners act before problems become emergencies. The article maps practical detection steps, numeric cost ranges and example estimate line items, a clear comparison of traditional and trenchless approaches, EAV tables that compare methods and materials, and actionable maintenance practices to extend pipe life. Read on to learn diagnostic checks you can run today, how to assess repair vs full replacement, what to ask contractors and insurers, and which preventative strategies reduce the chance of future failures.

What Are the Common Signs of a Water Line Break Every Homeowner Should Know?

A water line break or failing service line usually reveals itself through a mix of visible, audible, and measurable signs that point to underground leaks or pipe deterioration. Identifying these signals early reduces property damage, lowers wasted water costs, and clarifies whether a localized repair or a full replacement is needed. Homeowners should pair visual inspection with simple meter checks and pressure tests to form a quick diagnosis before contacting a professional. The sections below unpack the top signs and offer step-by-step homeowner checks to confirm whether the main water line is the likely source of the problem.

How Does Low Water Pressure Indicate a Failing Water Line?

Low water pressure across multiple fixtures often signals a main service issue such as partial blockage, a significant leak, or a failing shut-off/curb stop rather than a single fixture. To test, first compare pressure at different taps, then isolate the home by closing indoor valves and observing the meter; a continuing flow on the meter with all fixtures off strongly indicates an underground leak. A simple pressure gauge attached to an outdoor spigot can quantify pressure loss and help determine whether the problem is whole-house versus localized. If neighbors report normal pressure while your property shows low readings, escalate to a professional assessment because distributed low pressure typically points to a main service problem.

What Does Discolored or Rusty Water Reveal About Pipe Corrosion?

Discolored water — brown, red, or yellow — commonly indicates internal pipe corrosion, disturbed sediments, or failing galvanized materials that release rust into the flow. Brown or reddish water often means iron or rust particles, while yellow staining can signal sediment or mineral disturbance; immediate flushing and avoiding consumption until clarification help reduce risk. Running cold water for several minutes and checking whether discoloration clears can indicate whether the issue is transient or ongoing; persistent discoloration warrants a plumber’s inspection and potentially a water quality test. Corrosion-related discoloration often accompanies age-related deterioration and can be a deciding factor for replacement rather than repeated repairs.

How Can Unexplained Wet Spots or Puddles Signal Underground Leaks?

Unexpectedly lush or soggy patches in the yard, especially when weather has been dry, frequently point to subterranean leaks from the service line saturating soil and surfacing in puddles. To narrow the source, perform a meter test: turn off all water inside and outside, record the meter, wait 30–60 minutes, and re-check for movement — any change suggests active leakage. Distinguish irrigation or drainage issues by inspecting irrigation valves and by checking if the soggy area is near the suspected pipe route; patterns along linear paths or depressions are more consistent with leaking lines. Persistent wet areas near foundations, sidewalks, or driveways should prompt immediate professional evaluation because ongoing undermining can cause structural damage.

Why Do Sudden Spikes in Water Bills Suggest Hidden Water Line Damage?

A sudden, unexplained increase in water bills often reflects continuous hidden leakage or a failing service saddle that allows persistent flow to escape into the ground. Homeowners can quantify potential loss with a simple meter-based test: note meter reading, isolate all water use, then check the differential over a known interval to estimate gallons lost and translate that volume into cost using local utility rates. For example, a constant leak of one gallon per minute equals about 4,320 gallons per three days — a measurable expense on monthly statements. When high bills coincide with any of the other signs above, hidden water line damage becomes a prime suspect requiring diagnostic inspection.

What Are the Warning Noises and Foundation Cracks Related to Water Line Issues?

Audible warnings such as gurgling, banging (water hammer-like sounds), or constant trickling noises within floors or walls can point to pressurized leaks or pipe movement under load. Simultaneously, foundation cracks, settling, or pavement heaving near supply routes may indicate soil erosion from leaking water undermining structural support. These symptoms together escalate the urgency because they suggest the leak has advanced to a point where structural repair and full line replacement may both be necessary. If you hear persistent noises or see new structural cracks, shut off water to the property if safe to do so and seek an immediate professional inspection.

How Much Does Main Water Line Replacement Cost and What Factors Affect It?

Main water line replacement costs vary widely, but homeowners can expect a clear range depending on method, material, access, and restoration needs; knowing the typical line items helps compare bids effectively. Average total costs often fall between modest-to-high ranges based on project length and complexity, and the per-linear-foot cost differs for trenched versus trenchless options. The table below compares replacement methods by cost per linear foot, typical project totals, disruption level, and expected timeline so homeowners can quickly gauge scale. After the table, guidance explains how to read contractor estimates, typical line items you’ll see, and non-branded example service packages to use as comparison anchors.

Different replacement methods have distinct cost and disruption profiles:

Approach	Cost per linear foot	Typical project cost	Disruption level	Typical timeline
Trenched replacement	$50–$200	$1,500–$10,000+	High (excavation, landscaping)	1–4 days for install; restoration may add weeks
Trenchless (pipe bursting)	$75–$300	$3,000–$12,000+	Low–moderate (access pits only)	1–3 days
Trenchless (CIPP lining)	$60–$250	$2,000–$9,000	Low (minimal surface work)	1–2 days

What Is the Average Cost Range for Main Water Line Replacement?

National averages vary, but many homeowners encounter totals in the low-thousands for short, accessible runs and mid-to-high thousands for long runs or complex sites; a compact, typical range is often cited between roughly $2,000 and $10,000 depending on method and locale. Short service runs (20–50 feet) with direct access and basic restoration commonly sit at the lower end, while longer runs that cross driveways, sidewalks, or require deep excavation escalate costs significantly. Always ask contractors for a per-foot breakdown and sample calculations for your measured run to verify transparency. Understanding variability helps set realistic budget expectations and avoids surprises when permits or restoration work are added.

How Do Trenched and Trenchless Replacement Costs Compare Per Linear Foot?

Per-foot ranges differ because trenchless methods require specialized equipment and sometimes higher material costs, while trenched methods involve more labor and landscape restoration expenses. A simple calculation example: a 50-foot trenched install at $100/ft equals $5,000 before restoration; the same 50 feet with pipe bursting at $160/ft equals $8,000 but may save several thousand in landscaping reconstruction. Trenchless becomes cost-effective when restoration costs for trenched work (driveway replacement, mature landscaping) would exceed the premium for trenchless equipment. Compare bids that itemize excavation, pipe, fittings, labor, permits, and restoration — the per-foot figure alone can be misleading without those line items.

Which Factors Influence Total Replacement Costs: Labor, Materials, Permits, and Landscaping?

A full estimate usually breaks down into excavation/trench work, pipe and fittings, labor, permits and inspections, traffic control if needed, and final restoration (landscaping, concrete, asphalt). Site-specific drivers include depth to the pipe, soil type, root intrusion, proximity to utilities, and access restrictions such as narrow yards or required lane closures. Homeowners can reduce cost surprises by marking utilities, providing clear access, and obtaining multiple written estimates that list each cost category. Transparent bids will separate equipment mobilization and restoration so you can compare like-for-like rather than only headline totals.

When Should Homeowners Choose Repair Over Full Water Line Replacement?

Choosing repair versus replacement depends on age of the pipe, location and extent of damage, frequency of failures, and cost-benefit over expected remaining lifespan. Favor localized repair when damage is isolated, the surrounding pipe is relatively new, and the repair cost is a sensible fraction of replacement; choose replacement when corrosion, multiple leaks, or systemic failures suggest ongoing future repairs would exceed replacement costs. A basic decision checklist helps: evaluate pipe age, frequency of incidents, water quality changes, and long-term property plans. Case examples typically show repair for single-socket leaks on a newer run and replacement for failing galvanized systems with repeated breaks.

What Are the Differences Between Traditional and Trenchless Water Line Replacement Methods?

Traditional (trenched) replacement and trenchless methods address the same problem with contrasting mechanics, disruption levels, and costs; understanding the steps and trade-offs helps homeowners choose the right approach for their site. Traditional replacement excavates along the pipe path, removes degraded pipe, installs new piping, and restores the surface — a straightforward method that works with complex alignments but raises restoration costs. Trenchless methods, including pipe bursting and cured-in-place pipe (CIPP) lining, minimize surface disturbance by using pits or access points and specialized equipment to rehabilitate or replace pipe beneath the surface. The subsections below describe each method, pros/cons, and the specific trenchless techniques so homeowners can weigh suitability based on soil, alignment, and landscape value.

How Does Traditional Water Line Replacement Work?

Traditional replacement begins with locating the existing service, marking utilities, and excavating a continuous trench along the pipe path. Workers remove the old pipe, install new pipe (commonly copper, PEX, or HDPE), pressure-test the system, backfill the trench, and then restore the surface — which can include regrading, reseeding, or repaving. Typical timelines depend on run length and site complexity but usually span one to several days for the pipe work with restoration adding additional time. Homeowners should prepare by clearing access, protecting plants, and understanding who handles permits and restoration.

What Are the Pros and Cons of Traditional Replacement?

Traditional replacement’s main advantages are method simplicity and wide applicability regardless of pipe condition or alignment; it is reliable for complex repairs where trenchless methods cannot reach. Disadvantages include significant surface disruption, longer total project timelines due to restoration, and potentially higher total cost once landscaping or hardscape replacement is included. Use cases favor traditional methods when pipes shift under structures, alignment is irregular, or soil conditions prevent trenchless equipment operation. Comparing the likely restoration expense to the trenchless premium is key to making an informed decision.

How Does Trenchless Replacement Minimize Excavation and Disruption?

Trenchless approaches replace or rehabilitate service lines using access pits instead of long trenches, pulling new pipe through or installing liners that form a new internal pipe wall, thereby reducing surface disturbance and restoration needs. This works best where the existing pipe follows a reasonably straight path and there is space for launch and reception pits, and when soil conditions allow hydraulic or mechanical insertion. Limitations include difficulty when pipes have multiple critical bends, severe collapse, or unknown utility congestion that prevents safe bursting or lining. For many homeowners, trenchless means faster completion and lower restoration costs, making it attractive where landscape value is high.

The selection of a trenchless pipeline replacement or rehabilitation method is contingent upon the physical characteristics of the existing water main, encompassing pipe length, diameter, material, and the prevailing subsurface soil conditions.

Selection of Trenchless Water Pipe Replacement Methods: Key Considerations

Selecting a trenchless pipeline replacement or rehabilitation method is contingent upon the physical characteristics of the existing water main, encompassing pipe length, diameter, material, and the prevailing subsurface soil conditions. Additional determinants include the projected service life of the renewed pipe, budgetary constraints, and the potential for public service disruption.

What Are Pipe Bursting and Pipe Lining Techniques in Trenchless Replacement?

Pipe bursting replaces the pipe by fracturing the old pipe outward while simultaneously pulling a new pipe into place, ideal when existing alignment is intact but the old pipe is structurally compromised. Cured-in-place pipe (CIPP) lining involves inserting a resin-saturated liner that cures in place to form a new pipe inside the old one, best for pipes with adequate internal clearance and where structural collapse is limited. Each technique has procedural steps: site pits, cleaning and prep, equipment insertion, installation and curing, then minimal restoration. Choose bursting for full replacement capability and lining when the existing pipe can serve as a host for the new inner pipe.

What Are the Advantages and Disadvantages of Trenchless Methods?

Trenchless advantages include faster installation, less landscape and hardscape restoration, and reduced disturbance to daily life; disadvantages include higher equipment and mobilization costs, limitations with complex alignments, and potential need for specialized permits. ROI considerations should include avoided restoration costs and the non-monetary value of preserving mature trees and hardscapes. When evaluating trenchless bids, ask for references and photos of similar local jobs to verify capability and to confirm whether the method will work on your soil type. These comparisons help homeowners balance short-term costs versus long-term property value.

Which Water Pipe Replacement Materials Are Best for Homeowners?

Choosing a pipe material blends cost, longevity, corrosion resistance, and local code acceptance; the right material depends on site conditions, water chemistry, and installation method. The table below compares common materials by average cost per foot, typical lifespan, corrosion resistance, and primary pros and cons to help homeowners decide. After the table, short profiles explain when copper, PEX, CPVC, galvanized steel, PVC, and HDPE are commonly recommended or avoided.

Before the table: this comparison summarizes material trade-offs that affect both initial cost and long-term performance.

Material	Avg cost per foot	Lifespan (years)	Corrosion resistance	Pros / Cons
Copper	$6–$12	50–70+	High (but subject to galvanic issues)	Durable, antimicrobial; higher material/labor cost
PEX	$2–$6	30–50	High (flexible, resists scale)	Flexible, easier install; restricted in some outdoor uses
CPVC/PVC	$1–$4	25–50	Moderate (chemical-resistance varies)	Low cost; temperature/UV limitations
Galvanized steel	$3–$6	20–50 (corrodes)	Low (prone to internal rust)	Often requires replacement due to corrosion
HDPE	$3–$8	50–100	Very high	Excellent for trenchless installs; flexible and corrosion-resistant

Why Is Copper Considered the Gold Standard for Water Lines?

Copper is prized for durability, antimicrobial surface properties, and long historical performance in service lines; its lifespan commonly exceeds several decades in many water chemistries. Copper resists many forms of degradation but requires proper grounding and attention to galvanic corrosion when connected to dissimilar metals. Installation requires soldered or mechanical fittings and typically commands higher labor rates, which impacts total project budgets. Given its long service life, copper remains a strong choice when durability and proven reliability are primary homeowner priorities.

What Are the Benefits and Limitations of PEX Piping?

PEX offers flexibility, quick installation, freeze-resistance in some applications, and lower material and labor costs compared with rigid metals, making it attractive for many residential projects. Connections are typically crimped or push-fit, reducing labor time, and PEX performs well in corrosive or soft-water conditions because it does not corrode. Limitations include sensitivity to UV exposure (not suited for long-term outdoor exposure) and variable acceptance in some municipal codes for potable outdoor service lines. PEX is often the preferred option for interior retrofits and for service lines installed in protected trenches.

How Do CPVC, Galvanized Steel, PVC, and HDPE Compare in Durability and Cost?

CPVC and PVC are low-cost plastic options useful for many non-metallic installations but may have temperature and pressure limitations; galvanized steel is now commonly replaced due to internal corrosion and reduced flow over time. HDPE stands out for trenchless replacements because of its flexibility, fusion-welded joints, and excellent corrosion resistance, often delivering long lifespans where buried conditions are aggressive. When evaluating materials, consider soil chemistry, expected service life, and whether trenchless methods will be used — HDPE and PEX pair well with trenchless installation, while copper remains versatile for traditional installs.

How Do Local Regulations Affect Your Choice of Pipe Material?

Municipal codes and water utilities often dictate acceptable pipe materials for service connections and may require permit-reviewed materials and installation practices; always check local rules before ordering materials or scheduling work. Steps to verify include contacting the local building department, reviewing utility service line requirements, and confirming inspector expectations for materials and tracer wire when burying plastic pipe. Some jurisdictions restrict outdoor use of PEX or require specific backfill and depth standards for non-metallic piping. Confirming regulations early avoids costly rework and permit delays.

How Long Do Water Lines Last and How Can Homeowners Extend Their Lifespan?

Typical lifespans vary significantly by material, environment, and maintenance: copper and HDPE often offer the longest service life, while galvanized steel and some plastics may fail earlier under corrosive conditions. Regular inspection, proactive testing, and simple homeowner actions can detect early issues, delay failures, and maximize the functional life of your service line. The table below summarizes typical lifespans by material followed by actionable maintenance practices, seasonal protections, and smart monitoring options homeowners can implement.

Material	Typical lifespan (years)	Key failure modes
Copper	50–70+	Corrosion in aggressive water, galvanic action
PEX	30–50	UV exposure, mechanical damage
CPVC/PVC	25–50	Brittleness with age, thermal stress
Galvanized steel	20–50	Internal rusting and reduced flow
HDPE	50–100	Very low corrosion, joint integrity issues if poor fusion

What Is the Typical Lifespan of Different Water Pipe Materials?

Lifespan depends on both material properties and environmental stresses: copper and HDPE often last multiple decades, PEX and CPVC have generational lifespans under protected conditions, and galvanized steel commonly needs replacement sooner due to internal corrosion. Water chemistry (pH, dissolved oxygen, chloride levels) and soil aggressiveness directly influence corrosion and degradation rates. Use these lifespan ranges as planning benchmarks when evaluating repair vs replacement decisions. Consider lifecycle cost, not just upfront price, when choosing replacement materials.

What Preventative Maintenance Can Help Detect Leaks Early?

Regular homeowner checks include monthly visual inspections for soggy areas, an annual meter test to detect hidden leaks, and scheduled professional video pipe inspection every 3–7 years depending on pipe age and prior issues. Tools such as pressure gauges, simple acoustic leak detectors, and whole-house leak sensors help catch small leaks before they escalate, while professional video inspection provides internal condition data that informs repair versus replacement choices. Establishing a baseline condition early and monitoring changes over time is the most cost-effective way to prevent catastrophic failures.

How Can Tree Roots and Winter Conditions Affect Water Line Longevity?

Tree roots seek moisture and penetrate weak joints or compromised bedding, accelerating leaks and pipe degradation; planting large trees away from known pipe routes and using root barriers reduces this risk. Winter freeze-thaw cycles cause heaving and thermal stress on shallow pipes, making proper burial depth and insulation essential in cold climates. Prevention strategies include maintaining proper burial depth, insulating exposed outdoor piping, and designing irrigation layouts to avoid concentration near buried services. Addressing landscape planning and seasonal protection proactively extends service life and reduces emergency repairs.

What Are Smart Leak Detection Devices and How Do They Help?

Smart devices range from simple sensor pads placed under vulnerable fixtures to whole-home systems that monitor flow and automatically shut off water on detecting abnormal patterns; these devices provide early alerts and can dramatically reduce water loss and property damage. Meter-based monitors track cumulative flow and flag uncommon continuous flows that indicate leaks, while localized sensors detect moisture in specific rooms or beneath appliances. Advantages include immediate detection and automated responses; trade-offs include purchase and installation cost plus occasional maintenance. Integrating smart monitoring with scheduled professional inspections multiplies the protection value.

What Should Homeowners Know About Insurance and Hiring Professionals for Water Line Replacement?

Understanding insurance nuances and knowing how to vet contractors prevents costly misunderstandings and ensures a smoother replacement process; homeowners should confirm coverage, ask about service-line add-ons, and get multiple written estimates. Typical insurance policies often exclude gradual wear-and-tear or pre-existing conditions but may cover sudden, accidental damage; service-line coverage or utility protection plans fill gaps for many underground repairs. The EAV table below outlines common coverage types, typical inclusions and exclusions, and deductible/limit expectations to guide homeowner conversations with insurers. After this, practical hiring guidance explains verification steps, red flags, and sample questions to request from contractors.

Coverage type	Typical coverage	Common exclusions / typical limits
Standard homeowners policy	Sudden accidental events (interior water damage)	Gradual underground pipe failure usually excluded; high deductibles
Service-line coverage (endorsement)	Underground repairs for service lines up to policy limit	May exclude wear-and-tear; limited annual caps
Utility or municipal relief programs	Partial cost-sharing or reimbursement	Eligibility varies; may not cover private property lines

Does Homeowners Insurance Cover Water Line Replacement and What Are the Limitations?

Homeowners insurance commonly covers sudden, accidental interior damage caused by water but often excludes underground service line failures and gradual deterioration, which means repair or replacement of the buried pipe may be out-of-pocket. Coverage nuances vary by policy: sudden bursts can trigger interior damage coverage while the pipe repair itself might require a service-line endorsement or separate utility coverage. Homeowners should read policy exclusions carefully, ask insurers about service-line add-ons, and document damage thoroughly when filing claims. Contacting your insurer early clarifies options and prevents surprise denials.

What Is Service Line Coverage and Why Is It Important?

Service-line coverage (an endorsement or separate product) typically helps pay for repair or replacement of the service line between the home and the utility connection, reducing potentially large out-of-pocket expenses for buried pipe failures. Coverage limits, deductibles, and specific inclusions vary widely; common benefits include contribution toward excavation, pipe replacement, and sometimes meter or curb-stop work. Because standard homeowners policies often exclude these items, service-line add-ons are valuable for homeowners in older neighborhoods or where aging utility infrastructure increases risk. Assess cost versus expected risk when deciding whether to purchase an endorsement.

How Do You Choose a Licensed Plumber or Contractor for Water Line Replacement?

Selecting a contractor requires checking license validity (where required), insurance coverage, relevant experience with trenchless methods if applicable, and references for similar projects. Ask for documentation showing commercial general liability and workers’ compensation, request photos and references for jobs of comparable scope, and confirm equipment capability for the method you prefer (trenched vs trenchless). Red flags include vague scopes, absence of written estimates, refusal to provide references, or demands for large upfront payments without clear milestones. A careful vetting process reduces risk of poor workmanship and costly rework.

What Questions Should You Ask Before Hiring and How to Verify Permits and Warranties?

Before signing any contract, ask about permits, inspection processes, warranty length on materials and labor, restoration responsibilities, daily timeline, and contingencies for encountering unexpected utilities or soil conditions. Require that the contractor pull all necessary permits and provide proof of scheduled inspections; contractors should supply a written warranty that lists duration and what it covers. Sample contractual items to request include an itemized estimate, start and completion dates, and a clause describing how change orders are handled. Verifying permits through the local building department and getting warranty documentation in writing are simple steps that protect homeowners.

What Are the Best Practices for Preventative Maintenance to Avoid Water Line Failures?

A proactive maintenance plan that combines routine homeowner checks, scheduled professional inspections, and targeted paid services reduces the likelihood of sudden failures and limits repair severity. Monthly visual checks, annual meter tests, and professional video inspections at intervals informed by pipe age and prior issues form a balanced approach. The list below outlines a practical maintenance cadence and homeowner actions to minimize risk, while the subsequent paragraphs detail specific DIY detection tips, landscaping practices to protect lines, and trigger events that should prompt professional scheduling.

Preventative practices checklist:

Monthly visual checks: Inspect yard for soggy spots, new depressions, and pressure changes at fixtures.
Annual meter test: Run a simple meter check yearly and after major events to detect hidden leaks.
Professional inspection schedule: Arrange video pipe inspections every 3–7 years depending on pipe age and prior problems.

How Often Should Homeowners Inspect Their Water Lines?

Homeowners should perform quick monthly inspections for visible signs and an annual meter-based test, while arranging professional internal video inspections every 3–7 years depending on pipe age and prior repair history. More frequent professional checks are prudent for older galvanized systems, homes with many trees, or properties that have experienced prior leaks. After major storms, construction nearby, or any sudden change in water quality or bills, schedule an inspection promptly. This cadence balances cost and risk, catching developing issues before they escalate.

What Are Effective DIY Leak Detection and Winterization Tips?

Effective DIY steps include running a meter test (shut off water, record meter, wait, re-check), using a pressure gauge on an exterior spigot to monitor unusual drops, and placing moisture sensors near vulnerable appliances. For winterization, insulate exposed outdoor piping, drain exterior lines before freeze weather, and close exterior shut-off valves where present to reduce freeze-related ruptures. These homeowner actions identify early leaks and mitigate seasonal risks, complementing periodic professional assessments. Combining DIY monitoring with scheduled professional services provides the best protection for buried lines.

How Can Proper Landscaping Protect Water Lines from Damage?

Proper landscaping practices include planting trees a safe distance from known pipe routes, using root barriers between large root systems and buried pipes, and avoiding heavy irrigation directly above service lines to reduce soil saturation and root attraction. Maintain clear records of pipe locations and use them when planning plantings or hardscapes; prefer shallow-root shrubs instead of large trees near lines. Good drainage and avoiding concentrated water flows near foundations prevent soil erosion that can expose or stress buried pipes. Thoughtful landscape planning prevents roots and water from becoming long-term threats.

When Should You Schedule Professional Maintenance or Replacement?

Schedule professional service when you observe repeated leaks, persistent discoloration, sudden chronic pressure loss, or when meter tests show ongoing unseen flow; also consider replacement when pipe age or material suggests imminent failure. Other triggers include major property renovations, installation of significant hardscape where pipe realignment is required, or persistent water quality issues that testing links to service piping. For preventative maintenance, schedule a professional video inspection at the recommended interval based on pipe age and prior incidents. Prioritizing scheduled checks and responding to triggers reduces emergency repairs and long-term costs.
