2026 Boulder Water Budgets, Water Rates, Sewer and Stormwater Charges
Water budgets
Boulder uses water budgets, which are the amount of water a customer is expected to use during a specific month.
Increasing blocks
If you exceed your water budget, the water above budget is billed in higher-rate blocks.
AWC sewer billing
Residential wastewater quantity charges are billed using actual water use or Average Winter Consumption, whichever is less.
Charge type | Current posted amount / rule | What it means |
|---|---|---|
Water Block 1 | $5.65 per 1,000 gallons for 0%-60% of monthly water budget. | Lowest water-usage block. |
Water Block 2 | $7.53 per 1,000 gallons for 61%-100% of monthly water budget. | Normal within-budget upper block. |
Water Block 3 | $15.06 per 1,000 gallons for 101%-150% of monthly water budget. | First over-budget penalty-style tier. |
Water Block 4 | $22.58 per 1,000 gallons for 151%-200% of monthly water budget. | High usage above budget. |
Water Block 5 | $37.64 per 1,000 gallons above 200% of monthly water budget. | Very high use, often leaks or excessive irrigation. |
3/4-inch water service charge | Inside City $21.51; Outside City $32.27. | Monthly fixed water service charge before usage. |
1-inch water service charge | Inside City $36.23; Outside City $54.33. | Higher fixed charge for larger meter. |
Wastewater quantity charge | Inside City $8.86 per 1,000 gallons; Outside City $13.28 per 1,000 gallons. | Sewer/wastewater usage portion of bill. |
3/4-inch wastewater service charge | Inside City $17.20; Outside City $25.81. | Monthly fixed wastewater service charge. |
Single-family stormwater fee | Up to 15,000 sq. ft. parcel: $29.88; 15,000-30,000 sq. ft.: $36.15; 30,000+ sq. ft.: $42.44. | Flood/stormwater charge based partly on parcel size/impervious area. |
Budget interpretation tip: your bill includes a graph comparing actual monthly water use with your monthly water budget. The water budget applies to water-use charges only and does not include wastewater, stormwater or other fees.
High Boulder Water Bill: Water Budget, Leak, Sewer and Stormwater Checklist
Check block tier
A small usage increase can cost much more if it pushes you from Block 2 into Blocks 3, 4 or 5.
Check leaks
Running toilets, irrigation leaks, hose bibs, service-line leaks and softener issues can cause over-budget usage.
Use portal history
The usage dashboard can show one- or two-year trends, average daily cost and usage comparisons.
Check | How to inspect | What to ask Billing |
|---|---|---|
Water budget graph | Compare actual use with budget on the bill or portal. | “Which water block caused the bill increase?” |
Block 3-5 charges | Review usage above 100%, 150% and 200% of budget. | “Was the increase caused by over-budget water use?” |
Toilet leak | Listen for running, use dye test and inspect flapper/fill valve. | “Does this repair qualify for leak adjustment?” |
Irrigation | Check controller, broken heads, overspray, soggy areas and watering schedule. | “Can I request a water budget adjustment or conservation support?” |
Meter reading | Request meter-reading information; one free extra meter read may be available every six months. | “Was this actual read, special read or unusual meter read?” |
Wastewater AWC | Check whether wastewater quantity was based on actual use or Average Winter Consumption. | “How did AWC affect my sewer charge?” |
Stormwater fee | Look for parcel-size or impervious-area stormwater line item. | “Is this charge based on property characteristics rather than water use?” |
Well customer bill | Well customers billed by the City may only be charged for wastewater services. | “Is this bill wastewater-only because water comes from a well?” |
Payment carryover | Compare last bill, last payment and current balance. | “Is this new usage or prior balance?” |
Leak adjustment timing | Gather repair proof and submit within 90 days of the bill due date for the leak period. | “What proof and months are eligible?” |
Leak Adjustment Request: Deadline, Proof and What It Does Not Cover
90-day deadline
The request and repair documentation must be received within 90 days of the due date on the bill for the leak period.
Proof required
Submit plumber bill, receipt for parts, photos or written investigation/repair explanation.
Limited adjustment
The adjustment can reduce excess usage charges, but it does not erase the bill or apply to monthly service charges and fees.
Leak rule | What it means | Action |
|---|---|---|
Repair proof required | Invoices and receipts are preferred; photos and written explanations may support the request. | Keep plumber invoice, parts receipt and repair date. |
No proof alternative | Usage must return to normal the following month, and account holder/agent must provide written investigation statement. | Explain what was checked and fixed. |
Two consecutive months | Adjustment policy covers a maximum of two consecutive bills for detection and repair time. | Identify the two affected bills clearly. |
Three adjustments maximum | Maximum of three adjustments per property and same account holder. | Ask if prior adjustments exist. |
Seasonal use excluded | Gardening, filling pools, washing vehicles, theft, vandalism or negligence may not be approved. | Do not submit ordinary irrigation increase as leak adjustment. |
Processing time | City FAQ says adjustment may appear on next one or two bills and to allow 6-8 weeks during irrigation season. | Keep paying current charges unless Billing gives different instructions. |
Rate effect | Excess leak water is generally billed at lower Block 2 base rate, not erased completely. | Expect a reduced bill, not a normal no-leak bill. |
Questions | Email UTB@bouldercolorado.gov or call 303-441-3260. | Ask whether your repair proof is sufficient before deadline expires. |
Water Outage, Main Break, Leak or Service Disruption
Call, do not submit online
For water service disruption or main break, call 303-441-3200. The City says not to report urgent outages through Inquire Boulder.
Check outage map
The City’s water outage map shows planned and unplanned service outages confirmed by city staff.
Give exact details
Report address, cross street, visible water, pressure issue, no-water status, photos if safe and whether neighbors are affected.
Problem | What to say | What to do next |
|---|---|---|
Water main break | “Water is bubbling/running at [address/cross street].” | Stay away from flooded pavement and call 303-441-3200. |
No water | “My address has no water; neighbors [are/are not] affected.” | Check outage map, then call if not listed. |
Low pressure | “Low pressure affects [all fixtures/one fixture/neighborhood].” | Ask whether maintenance, main break or service-line issue is active. |
Leak at meter / street | “Water is leaking at [meter/street/hydrant/location].” | Do not open or tamper with meter equipment. |
Frozen indoor pipe | “This appears to be inside my building.” | The City page advises contacting a private plumber for indoor maintenance issues. |
No hot water only | “Cold water works but no hot water.” | Contact property owner or plumber; it may not be a City water outage. |
Sewer emergency | “Wastewater is backing up from [fixture/location].” | Call Utilities emergency route and avoid contaminated water. |
After-hours urgent issue | “This is an after-hours emergency at [address].” | Call 303-441-3200 and follow after-hours emergency prompt. |
2026 Drinking Water Quality, Sources, PFAS and Lead Service Line Notes

Water quality topic | Official Boulder context | Customer action |
|---|---|---|
Annual report | 2026 Drinking Water Quality Report summarizes 2025 testing. | Open the report before relying on door-to-door water filter claims. |
Water standards | City announcement says Boulder met federal and state water quality standards and had no violations in 2025. | Use the report for official contaminant information. |
Sources | Sources include Middle and North Boulder Creek watersheds, Carter Lake and Colorado-Big Thompson watershed. | Use source info for seasonal taste/odor context. |
Monitoring scope | The City says it monitors 500+ substances, including chemistry, bacteria, metals, disinfection byproducts, pesticides, pharmaceuticals, hormones, radionuclides and PFAS. | Ask the Drinking Water Program if you need help interpreting a result. |
PFAS | Boulder says 2023 PFAS testing found no detections of PFAS compounds in city drinking water. | Check latest report and data page for current context. |
Discolored water | Can happen temporarily from main breaks, hydrant flushing or construction water use. | Flush cold taps for several minutes; call if it does not clear after following guidance. |

Drinking-water contact | drinkingwater@bouldercolorado.gov or 303-441-3200. | Provide address, issue, timing and whether neighbors are affected. |
Renters, Mobile Home Parks, Wells and Property Managers
Provider warning: not every “Boulder” address is billed directly like a single-family City utility account. Mobile home parks, renters, property managers, well customers and addresses outside city limits may have different billing and responsibility rules.
Situation | Boulder rule / route | What to ask |
|---|---|---|
Tenant pays bill directly | Tenant can create a Customer Billing Portal account using required information on the bill. | Ask landlord for the bill or customer/account number if lease requires tenant payment. |
Tenant wants one-time payment | Tenant can use Quick Pay without logging in. | Use exact customer-account number and account name from bill. |
Owner with multiple rentals | Owner can connect additional accounts in User Profile if customer numbers differ. | Keep accounts linked but avoid giving tenants more access than needed. |
Property manager | Property managers can link accounts and access usage history/bill copies. | Use portal access rules for each client/property. |
Mobile home park resident | City bills mobile home park owners monthly; park owners determine how to charge residents. | Review lease or ask park owner how water/sewer charges are calculated. |
Mobile home leak | Park owners repair leaks between City meter and individual homes; homeowners repair leaks inside home. | Report unresolved park-side leaks through the appropriate City route. |
Well customer | If water comes from a well, the City does not manage well water quality/quantity or collect well-water fees. | If you receive a City bill, it may be wastewater-only. |
Out-of-city provider | Some areas have other water sources regulated through Boulder County Public Health or Colorado health/environment agencies. | Confirm provider before using City of Boulder portal. |
Financial Hardship, Extensions and Practical Help
Call Billing early
Call 303-441-3260 before the bill becomes urgent. Ask about current options, hardship resources and payment timing.
Use community support
The City links to local organizations helping community members experiencing financial challenges.
Reduce usage
Use water conservation support, leak checks and water budget adjustments if the bill is driven by usage rather than prior balance.
Need | First step | What to say |
|---|---|---|
Cannot pay full bill | Call 303-441-3260. | “I can pay [amount] today and need to know current options before the due date.” |
Need community assistance | Use City community support link and local assistance resources. | “Which organizations are helping with utility bills now?” |
Payment made late | Call Billing with confirmation number. | “Has this posted, and is any balance still due?” |
Leak created bill spike | Repair leak and submit leak adjustment request within 90 days. | “Here is my proof of repair; which bill periods can be reviewed?” |
Water budget too low | Review water budget adjustment reasons and submit if eligible. | “Does my household/property qualify for a water budget adjustment?” |
