EC$78.47
A higher-use bill changes.
At 3,660 imperial gallons, the scheduled January 2027 domestic water charge is EC$78.47, up from EC$63.78 under June rates and EC$53.08 before June. The fixed minimum stays EC$24.42. ↗

Reliable water.
A fair cost.
Every household needs water it can count on. Every promise needs the people, money and rules to deliver it.
A visual guide to Saint Lucia’s water costs—and a practical programme to connect better service with household protection.
01 / The research in a minute
Follow the cost.
Measure the service.
The central policy choice is to pair funded household support with clear service duties and the capacity to meet them.
EC$26.81
The account structure matters.
Two households each using 1,800 gallons pay EC$26.81 more in January through one permitted shared-property account than through two eligible accounts. At lower use, sharing can reduce the combined charge.
Explore a shared account12.0%
Count the full household cost.
In an illustrative household with EC$1,200 in monthly resources, a EC$24.42 bill plus EC$120 spent coping with interruptions takes 12% of resources. The bill alone takes about 2%.

02 / Source to service
A connected system.
A household outcome.
Rainfall, source conditions, treatment, power, pressure and maintenance all shape whether water reaches the tap. Select a stage to see where policy can make a difference.
The journey to the tap
Every handoff matters.
Follow the four connected parts of a reliable water service. Select a stage to explore the practical work and the evidence to track.
01 / Source
Start with the catchment.
Water reliability begins where rain meets the land. Dry periods constrain available water; heavy rainfall can carry sediment into rivers and reservoirs.
- Policy action
- Protect catchments, monitor source flows and sediment, and connect drought planning to the water available for treatment.
- Evidence to track
- Source flows, reservoir conditions and interruptions caused by raw-water availability or quality.
The proposed programme connects these stages through service-zone records, funded response capacity and public reporting.
Recover water. Improve the record.
Repairing physical leakage can increase usable supply or reduce production costs. Correcting meters and billing errors improves recorded sales and revenue. Measure both effects separately, alongside pressure and supply hours.
When a functioning meter replaces estimated billing, a household’s recorded use can rise. Give customers the old and new readings, meter-change dates and a clear route to query the transition. ↗
Track investment through to service.
The September 2026 CDB project launch identified US$22.83 million of external finance and US$7.16 million in counterpart funding: US$29.99 million using the rounded totals. Follow procurement, works, testing and commissioning through to measured service. ↗
Reconcile the proposed local programme with funded pipeline and treatment projects. Each activity needs an owner, an operating budget and a clear account of which costs are additional. ↗
03 / Explore the bill
One protected minimum.
Three different curves.
The first 2,000 imperial gallons attract a fixed monthly domestic water charge. Consumption above that level enters progressively higher-priced blocks. Move the control to see the effect.

The first 2,000 gallons of domestic water keep a minimum charge of EC$24.42 in all three schedules. Sewer minimum charges change separately.

| June 2026 · current | EC$63.78 |
| January 2027 · scheduled | EC$78.47 |
Rates and calculation method
Each service has a minimum covering the first 2,000 gallons, a prorated rate for the next 1,000, and a higher prorated rate above 3,000. Water and sewer charges are each rounded half-up to cents, then added. One imperial gallon equals 4.54609 litres.
| Schedule | Minimum | Next 1,000 gal. | Per 1,000 above 3,000 |
|---|---|---|---|
| Before June 2026 | EC$24.42 | EC$12.21 | EC$24.92 |
| June 2026 · current | EC$24.42 | EC$16.77 | EC$34.23 |
| January 2027 · scheduled | EC$24.42 | EC$23.03 | EC$47.00 |
This consumption-charge model uses full monthly periods and whole imperial gallons. Sewer applies to eligible accounts at the same chargeable volume. Account-specific arrears, deposits and adjustments sit outside these calculations. Actual invoice conventions should be checked with WASCO.
Source: NURC final determination notice, June 2026, pp. 6–7 ↗. Schedule comparison calculated by SLPA.
Use the charge that applies to your account.
The explorer calculates domestic consumption charges. Sewerage is included only when you select an eligible water-and-sewerage account, using the same billed volume for both services. Actual statements can also contain arrears, credits or other account adjustments. ↗ ↗
Read January as the scheduled phase.
June 2026 rates are the current schedule in this research. The January 2027 phase is already set out in NURC’s notice. SLPA proposes a readiness review before that phase, with lawful corrective action and any justified formal tariff proceeding. ↗
How the calculation works
Start with the minimum. Add the relevant rate for each 1,000 gallons between 2,000 and 3,000. Add the upper-block rate for each 1,000 gallons above 3,000. Fractional blocks are proportional; round each service’s final charge to the nearest cent.
Charge = minimum + first-block use × first-block rate ÷ 1,000 + upper-block use × upper-block rate ÷ 1,000
One imperial gallon is 4.54609 litres. The old upper-block water rate used here is EC$24.92, as printed in the final notice. This also reproduces the earlier regulator’s EC$53.08 worked example; a EC$24.82 entry elsewhere in the report is inconsistent. The 3,660-gallon example is a fixed comparison volume. ↗ ↗ ↗
Water and sewerage are VAT zero-rated. The Health and Citizen Security Levy guidance excludes VAT zero-rated services, so these calculations apply no tax uplift. ↗ ↗
04 / The household view
The meter tells
part of the story.
Household size, shared accounts, income and the cost of getting water during interruptions all affect affordability. A useful protection programme sees the people behind the account.
03 / Count the full cash cost
Illustrative householdsWater costs reach beyond the bill.
Coping expense covers cash spent obtaining water: for example, purchased water, delivery or refills. Enter other essential spending before water. For the shared-property scenario, all amounts cover both households together.

Household resources, use and coping expenses are illustrative assumptions. Measuring how many households face hardship requires survey and account data. Figures are monthly EC$. Your inputs stay in this page for this visit.
Design access around households.
A tenant may pay through a landlord. Several households may share a meter. A family may have no direct utility account. Assessment and appeals should accept workable evidence of residence, resources and water costs, while checking duplicate claims.
Cap account credits at eligible charges. Establish a separately authorized route for people who need emergency access or support without a direct account.
Measure coping costs carefully.
Record purchased water, transport, pumping energy and other direct costs, alongside time spent collecting water and missed activities. For equipment, distinguish the cash needed upfront from an annualized cost, and avoid counting both in the same total.
Household survey evidence and a small local baseline should calibrate eligibility, take-up and support levels. The examples here show mechanisms; their inputs are available for inspection and adjustment. ↗
05 / SLPA’s proposed programme
Service standards.
Household protection.
Capacity to deliver.
Adopt a funded Water Service and Household Protection Programme through the institutions Saint Lucia already has. Begin in up to three service zones, then use verified results to decide what expands.
Make the service promise specific.
Set costed standards for notice, updates, pressure, emergency access and complaint handling. NURC should settle the legal instrument and verification process; WASCO should plan staffing, spares, communications and repairs around it.
Fund household protection explicitly.
Use a defined subsidy instrument, transparent eligibility, an accessible appeal and timely reimbursement. Include tenants and shared-account households in programme design. Preserve funding for treatment, safe operation and essential maintenance.
Repair within a measured service area.
Select zones using service stress, hardship, technical feasibility and existing works. Validate bulk and customer measurements, record a usable baseline, then carry out bounded repairs and pressure management with a trained response team. Urgent repairs and emergency protection proceed immediately; record their timing in the baseline.
Keep essential facilities supplied.
Assess storage, safe filling, backup power and delivery arrangements at six critical sites in the planning envelope. Document usable stocks, demand and who triggers an alternative supply. Budget for cleaning, testing and maintenance.
Publish a service and spending record.
Pair a lawful public summary with fuller regulatory returns. Show interruptions, pressure, quality, repairs, assistance reach, complaints and spending. Publish reasons for missed commitments and the corrective response.
Expand on the evidence.
Review continuity, quality, access, cost and operational capacity together. Show the actual observation period, weather and seasonal gaps. Keep effective measures, revise weak ones and fund recurring obligations before expanding.
The legal route from proposal to enforceable duty
The Water and Sewerage Act provides the sector framework. Sections 83–84 establish Cabinet’s subsidy route by Gazette Order, with NURC advice and review. NURC Act section 40 allows gazetted codes linked to service-licence compliance. The exact instrument should be checked against the operative licence and completed Service Standards Agreement. ↗ ↗
The June determination commits to publishing the Service Standards Agreement when completed. Quarterly returns go to NURC; this programme adds a legally settled public extract with appropriate privacy and confidentiality protections. ↗ ↗
Section 87 provides a route to remedial and compensation directions after an investigated, substantiated breach causing foreseeable damage. New automatic credits require adopted rules and funding. Reconcile the section’s legacy procedural cross-references before issuing complaint templates. ↗
A readiness review should produce reasons, corrective actions and any justified formal tariff proceeding. Missed service milestones do not automatically cancel January’s scheduled tariffs under the current notice.
06 / Fund the promise
Relief and reliability
need the same cash discipline.
A funded reduction in household payments can protect service capacity. An unfunded reduction can leave fewer resources for treatment and maintenance. Explore the accounting, then inspect the proposed budget.
04 / Follow the money
Illustrative cash modelFund the relief. Protect the service.
Reference gross bills are set to 100 units. Choose a scenario to see how receipts meet operating outflows, debt service and a separate maintenance reserve.
Reference
Total receipts90
Households 90 + public funding 0
Total outflows85
Operations 70 + debt 10 + reserve 5
Closing margin+5 units
90 units received cover 85 units of operating outflows, debt service and a separate maintenance reserve.
Equal funding, equal utility cash.
General and targeted relief both leave a margin of +5 when public funding is 3 and total receipts are 90. Their reach, fairness and administration require a separate assessment. Timely reimbursement matters in either design.
All values are assumed index units for a cash-accounting illustration. Current audited accounts and a cash bridge are needed to assess WASCO’s financing capacity.
Ask for a current cash bridge.
Reconcile bills, collections, arrears, operating payments, debt service, restricted project funds and essential maintenance. The public review found historical financial evidence and current project announcements; a usable current audited cash bridge remained an evidence request. The 2023 expense base and older collection figures need their dates and accounting definitions preserved. ↗ ↗

Staffing covers mobilisation and the full twelve months. The EC$35 monthly relief allowance and 500 household equivalents are planning assumptions to be calibrated against need. Eligible bill credits would be capped at eligible charges, with a separate lawful route for households without direct accounts. Quotations, funding decisions and reconciliation with existing projects are required before commitment.
The base is EC$956,000: EC$851,000 in non-transfer allowances plus EC$105,000 in relief. Contingency is EC$127,650. Major transmission works, new treatment capacity and land acquisition fall outside this envelope; continued operating costs require a recurrent allocation.
SLPA proposed programme, revised 11 October 2026. The range shows sensitivity to the specified procurement assumptions.
Twelve months of delivery capacity.
The EC$1,083,650 planning envelope includes staffing from mobilisation, instruments in up to three zones, repairs, six critical sites, emergency access and temporary support. Obtain quotations and reconcile existing allocations before appropriation.
The relief allowance assumes 500 household equivalents at EC$35 for six months. Calibrate these planning inputs with eligibility evidence and actual charges.
Keep the scope visible.
The earlier EC$1,030,400 first-90-day design included different activities, eight facilities and household storage vouchers. The new twelve-month design includes six facilities and no separate 100-household tank allowance. These are alternative scopes.
Major transmission works, land acquisition and new treatment plants sit outside this envelope. Operations after year one need a further allocation.
07 / From adoption to evidence
Make each step
reviewable.
Set an adoption date, available funds and named leads. Run the implementation clock alongside a public readiness review by 15 December 2026, before the January tariff phase.
- Day 30
Put the essentials in place.
Publish the tariff guide, programme owners, zone-selection criteria and agreement status. Start the incident log and current cash bridge.
- Day 60
Establish a usable starting point.
Aim for at least four weeks of valid baseline data where feasible. Check meters and pressure instruments, cost the standards and repairs, and authorize assistance.
- Day 90
Show what was delivered.
Publish the repair and spending record, a service summary and independently checked complaints and access barriers. Correct weaknesses.
- 15 Dec 2026
Review readiness for January.
Report the service-agreement status, operating funds, household support and unresolved risks. If adoption is late, publish an interim review with the remaining work and responsible offices.
- Month 12
Decide what continues.
Assess first-year implementation using the actual months observed. Publish seasonal gaps and recurring costs. A full twelve months of observation after activation needs a separately funded continuation.
Proposed response standards
A service promise
people can understand.
These starting standards require costing and lawful adoption. Restoration times should reflect the incident, safety checks and conditions at the end of the network.
Planned notice
Advance notice of a planned interruption.
First public update
After an unplanned incident is confirmed, then updates every four hours.
Priority triage
Assess critical-site needs; escalate a failed promised delivery within two hours.
Alternative-water assessment
Assess need by this point, or earlier as essential stocks require.
Complaints, access and a useful public scorecard
Give each complaint a traceable route.
SLPA proposes acknowledgement within one business day, initial assessment within three, and an outcome within ten where practicable, with updates at least every five business days. Keep a case number, evidence, reasons, assistance offered and appeal route. These are proposed programme standards.
Existing NURC guidance starts with the provider and allows unresolved complaints to move to the Commission. Regulation 16’s 48-hour prompt-response benchmark concerns the Commission’s response to a customer’s written communication. ↗ ↗
Publish the measures that matter.
| Measure | Record to publish |
|---|---|
| Continuity | Customer interruption-hours, affected accounts, dates and cause; identify missing logs. |
| Pressure | Share of valid monitored time within the adopted range; location and instrument coverage. |
| Water quality | Required samples, completed tests, results and corrective action. |
| Emergency access | Requests, promised and completed deliveries, missed commitments and critical-site stocks. |
| Repair performance | Work completed, repeat breaks, response time and restored service checks. |
| Household protection | Applications, approvals, payments, tenant/shared-account access and appeals, with privacy safeguards. |
| Financial capacity | Receipts, essential payments, maintenance provision, reimbursement delays and committed costs. |
Use an independent check and publish exceptions. Compare changes with rainfall, existing project commissioning, meter changes and the observed season. Expansion should follow safe, sustained service and affordable recurring operations.
The decision
Fund the people.
Repair the weak points.
Show the result.
Saint Lucia can begin with a bounded, measurable programme. The test is whether households receive a better service, can afford access, and can see how public promises are being kept.

Follow the reasoning.
This web edition brings the tariff calculations, household scenarios, programme design and delivery tests together. Sources are linked beside the relevant claims and collected below.
What the research establishes—and the next evidence to collect
The strongest numerical findings are reproducible calculations from published tariff schedules. Household and cash-flow examples isolate mechanisms using visible assumptions. Programme costs are planning allowances for a defined scope.
Priorities for the next evidence round are a current utility cash bridge, the operative licence and completed service agreement, verified service-area records, and household evidence linking costs to income, tenancy and shared meters. The public search’s evidence gaps describe what the study could establish.
JICA’s 2024 survey reported historical coverage of 98% and 24-hour service reaching 75% in the rainy season and 60% in the dry season. Those observations provide background and must retain their source period when used. A new programme needs a dated local baseline. ↗
Recent WASCO advisories document operational stress and responses. National hardship prevalence and current islandwide continuity require a broader dataset. ↗ ↗
The implementation plan responds to staffing, procurement and delivery constraints identified in CDB’s country-programme evaluation. Staff time and verification are funded from mobilisation. ↗
How to interpret the scenarios and budget range
Household resources, essential spending and coping costs are assumptions, editable in the explorer. Total water burden is utility charges plus direct coping costs divided by resources. Residual resources equal resources minus essential spending and water costs. Time burdens should be reported separately unless a defensible valuation is provided.
The cash model uses normalized units: gross bills of 100, receipts of 90 and essential outflows of 85. With equal public funding, general and targeted support preserve the same utility cash margin in the model. Distribution, administrative cost and take-up need separate evidence.
The budget starts with EC$851,000 in non-transfer allowances and EC$105,000 in temporary relief. A 15% contingency on the non-transfer allowances adds EC$127,650. The sensitivity range multiplies non-transfer allowances by 0.7 or 1.4, applies the same contingency rule, and holds relief fixed: EC$790,055–1,475,110.
A four-week baseline provides an operational starting point. Seasonal comparison and attribution need more observation, a clear record of other projects and independent verification.
Questions households and decision-makers often ask
Will every domestic bill stay at EC$24.42?
That is the protected water minimum for up to 2,000 imperial gallons. Higher consumption and eligible sewerage charges follow their own rates. Use the explorer to calculate each phase.
Does a shared meter always cost more?
The result depends on use and account eligibility. Low use can avoid a second minimum; higher pooled consumption can enter the upper tariff blocks. The shared-account explorer shows both outcomes.
How should a household dispute a bill?
Keep the bill, readings, meter-change details and complaint reference. Ask WASCO to explain the charge and resolve the issue. Unresolved complaints can be referred to NURC under its published procedure. ↗
Are the proposed response clocks already law?
They are SLPA’s proposed starting standards for costing and lawful adoption. Existing statutory rights and applicable licence duties continue to govern service and complaints.
Can support be paid from the pipeline account?
The June notice restricts that account to the specified raw-water project and requires prior NURC approval for another use. The household programme needs a separately authorized, funded route. ↗
What should determine expansion?
Verified service improvements, safe water, accessible support and complaints routes, and affordable ongoing operation. Publish the observation period and the factors that could explain changes.
