Monthly Water User Charges
Occasional utility rate increases are necessary to cover rising operating costs and construction costs associated with replacing or upgrading aging utilities infrastructure. In addition, new regional, state and federal regulatory requirements for upgraded treatment processes also increase utility costs. To learn more review this rate change document.
Utility revenue increases are considered by City Council in October of each year as part of the citywide budget process. Rates are set so that sufficient revenues are generated to support operations, maintenance and improvements for each of the city utilities.
The rate structure is based on "water budgets", or the amount of water that you are expected to use during a specific month. Each customer's water budget will be different based on their unique water needs, as well as their past usage levels. To learn more about how these are determined, or to request an adjustment, please see Water Budget Adjustments.

|Meter Size||Inside City||Outside City|
Average Winter Consumption (AWC)
The wastewater quantity charges for residential customers are billed using actual water use or Average Winter Consumption (AWC), whichever is less. AWC means the average water use per month during the most recent December through March time period. Non-residential customers are billed for wastewater quantity charges based on actual use or indoor water budget allocation depending on their selected water budget option.
Monthly Stormwater and Flood Management Fees
Owners of single-family dwellings within the city limits will pay the following monthly stormwater fees (including service charge).
|Size of Parcel||Fee|
|Up to 15,000 square feet||$19.64|
|15,000 to 30,000 square feet||$23.77|
|30,000 square feet or more||$27.90|
The fee for all non-single-family dwellings is individually calculated based on impervious square feet, for a total charge not less than $17.54
Stormwater service charge is $3.15
Impervious Square foot rate is $0.00719 per square foot
The city does not charge the customer for well water. Some customers get their water from a well and are sewer only customers, using the city’s wastewater service from the city. If a customer receives a water bill that has charges, then they are receiving city water. Information about individual wells, including certification, can be found on the County Assessor’s website.
Request a Water Budget Adjustment
The Utility Billing Office will grant water budget adjustments under certain circumstances, outlined below. If you feel that any of the below circumstances apply to you, please complete the appropriate water budget adjustment application form below and submit any required documentation.
Be sure to read the entirety of the form before sending it in. If your adjustment is approved, it will become effective the date the city received it.
Please note: The information provided in your application form could be subject to verification by other city departments.
Water budgets can be adjusted for the following reasons
- Number of people in household (Single-family residential accounts only): Water budgets for single-family residential customers are calculated assuming four people per household. If you have more than four people living in your household year round, you can apply for an adjustment. Your monthly water budget will increase by 1,000 gallons per person for each additional person in the residence. Please include the number of people living in the household and the first and last names of each person on the form. The adjustment application for number of people in household must be submitted by either the property owner or property manager. This type of adjustment expires one year from the adjustment licenses, leases or other records that show the number of persons per household as additional documentation.
- Medical needs: If a medical need requires a significant increase in the amount of water being used, please submit verification from your healthcare provider. All medical information will be kept confidential.
- Licensed in-home childcare or eldercare facility or co-op: If a residential dwelling is being used as a licensed childcare, eldercare facility or co-op, then you can apply for an adjustment.
- Irrigable area square footage (e.g., landscaping): Irrigable area of the property is used to calculate water budgets for outdoor watering needs.
- If you have made significant changes to your landscaping or feel that your irrigable area is incorrect, then you can apply for an adjustment.
- If you irrigate an area that you are required to maintain in the public right-of-way that is 200 to 300 square feet or more, then you can apply for an adjustment.
- The adjustment application for irrigable area must be submitted by either the property owner or the property manager. Please check your property as illustrated on the city’s map to determine the current irrigable area.
- View water and stormwater area map
- HOA Adjustments: If a Homeowner Association (HOA) is requesting an adjustment, then the HOA must provide a signed written agreement (between HOA and homeowner) or by-laws which state irrigation responsibilities.
- Number of dwelling units (Multifamily residential accounts only): Water budgets for multifamily residential customers are based on the number of dwelling units and bedrooms/unit in the building. If you feel that the number of dwelling units for your building is incorrect or if you have more than two bedrooms in any of your units, you can apply for an adjustment.
Your water budget will not be adjusted for any of the following reasons
- Evaporative (swamp) coolers, pools, spas, or hot tubs;
- Gardens; and
- In-home businesses or hobbies that use an increased amount of water.
Commercial/industrial/institutional (CII) customers can now choose from three water budget options. Each CII account will only be able to change budget options once per year. If you are submitting an adjustment, please carefully read the appropriate adjustment form and include the required documentation.
- Water Budget Adjustment Application Form for Commercial/industrial/institutional (CII) Accounts
- Efficiency-Standard Water Budget Option Form for CII Accounts
Historical Monthly Use (HMU )
The HMU budget is calculated using a rolling three-month average for each individual month. For example, the average of the past three January's use would be next year's January budget.
AWC with Irrigation
The AWC with Irrigation budget is similar to the single-family budget in that it is comprised of both an indoor water allocation and an outdoor water allocation.
This option allows for a specific customized water budget. The customer must hire a professional engineer to evaluate and recommend a personalized indoor budget, which then must be reviewed and approved by the city. The customer will be charged a fee for the city review.
Water Budgets Explained
The City of Boulder has a water rate structure that uses "water budgets", or the amount of water that you are expected to use during a specific month. Each customer's water budget will be different based on their unique water needs, as well as their past usage levels.
Water budgets may vary monthly based on seasonal outdoor watering needs. No matter what your water budget is, you will only be billed for the water you use. View water budget rules.
Water budgets help promote water conservation. If you stay within your budget, you pay less for the water you use. If you exceed your budget, you pay more for the water you use.
Your utility bill includes a graph that shows your monthly water use compared to your monthly water budget. This graph will show whether your actual water use was above, below or equal to your monthly water budget.
Access your water budget, usage statistics and pay your bill online at MyBoulderUtilityBill . If you have questions about your water budget, contact Utility Billing. View water budget frequently asked questions (FAQs).
The water budget only applies to water-use charges and does not include other costs such as wastewater, stormwater, other fees, etc.

Know Your Water Meter
Locate your water meter
Water meter pits are typically located in the area between the sidewalk and street (called the right-of-way), or 1.5 feet from the sidewalk. The pits are covered by round metal lids marked with a "Water Meter" imprint.
Water meter readings
The City of Boulder collects water meter readings from radio transmitters installed in or near the meter pits. City vehicles equipped with mobile data collection systems receive the signals while driving past the meter pits. Each transmission takes 1/30 of a second, with a typical operating range of 500 feet, depending on broadcast signal and location.
Maintain access to your water meter
Obstacles that may block the radio signals include building materials, foliage and metal objects located between the street and the meter pit. Therefore, it is very important that customers maintain clear access to their water meters from the public right-of-way.
As part of the city code, all city water customers are responsible for the upkeep of the area between their meter pit and the street. Please assist us by trimming foliage and by clearing snow and ice from the lid of the meter pit. Landscaping or fencing should be kept at least 1-3 feet from the meter pit.
Maintain access to your water meter to assist us with:
- Emergency shutoffs (for frozen pipes) when you are away from home or are unable to turn off the water yourself; and
- Emergency water meter maintenance.
If you do not maintain access to your water meter pit, it may delay emergency response times and end up costing you (and the city) more money.
Understand Water Meters in Mobile Home Parks
Mobile home park owners
The City of Boulder classifies mobile home parks as multifamily residences and bills mobile home park owners monthly. Each park receives a water budget based on indoor and outdoor allocations, such as the number of homes served and the amount of landscaped area. The indoor allocation for each residential dwelling unit is set at 4,000 gallons per month. This allocation is adjusted seasonally to account for varying monthly water requirements. Utility accounts are charged a higher rate for water when they exceed their water budget.
Individual mobile home owners
Park owners are responsible for determining how to charge park residents for utilities. Residents are encouraged to refer to their lease for information about utility related charges. The city does not provide metering for individual mobile homes or provide individual bills.
Parks served by City of Boulder
- Boulder Meadows
- Vista Village
- Orchard Grove
The following parks are located outside of city limits but receive their drinking water from the city through special agreements:
Mobile home park owners are responsible for repairing any leaks that occur between the city water meter and the individual homes. Homeowners of a mobile home are responsible for finding and repairing leaks within their home. Tips on how to find and fix a leak can be found at the city's Finding and Fixing Leaks webpage.
Leaks between the city water meter and outside of individual homes should be reported to the management of the park. If the park owner fails to repair a leak in a timely manner, they may be in violation of city ordinances. Leaks that are not addressed by the park owner in a timely manner should be reported to the city. To report a leak, please call 303-441-3200.
For all other urgent water issues please 303-441-3200 between 8 a.m. and 5 p.m., Monday-Friday. After hours, weekends and holidays please call 303-441-3200 and it will forward to the appropriate staff. Please ALWAYS call the listed phone numbers to report a leak and do not report via Inquire Boulder. This system is not designed to manage urgent and emergency service requests and is NOT monitored 24-7. The city will need specific information about the location of the problem and any associated evidence so that it can be quickly investigated.
Residents of parks that are served by City of Boulder water can obtain water quality information at the city's Drinking Water Quality website, sending an email to firstname.lastname@example.org or calling 303-413-7350.
Mobile home parks served by providers other than the city Utilities Department can obtain water quality information through Boulder County Health Water Quality and/or Colorado Department of Health Water Quality.
Each park has one or more water service lines that connect to an adjacent city water main. The piping that delivers water from the property line to individual homes is privately owned and maintained by the park owner.
- Park residents are encouraged to review their lease or contact their park owner to determine how they are billed for drinking water. If you live in a park where each unit has a water meter read by the owner, you may be able to reduce your bill through more efficient use in your unit.
- Information about the city's water conservation program and available services is available on the city's Water Conservation website.
- In parks where the owner determines costs through other methods, residents may be able to work with park owners to improve efficiency of overall water use in the park to reduce costs.

Locate an Underground Utility
- Property owners are required to have underground utilities located before doing any digging, even for small projects like planting trees and shrubs.
- The depth of utility lines varies and there may be multiple utility lines in a common area and damaging a utility can disrupt service to an entire neighborhood, harm you and those around you and potentially result in fines and repair costs.
- Call 811 a few days prior to digging, and your call will be routed to your local One Call Center.
- Tell the operator where you're planning to dig, what type of work you will be doing and your affected local utilities.
- The City of Boulder Public Works Department and other utility companies will be notified about your intent to dig.
- Within a few days, a locator will mark the approximate location of your underground lines, pipes and cables, so you'll know what's below - and be able to dig safely.
Learn About or Report Drinking Water Quality
Water quality results
All drinking water, including bottled water, contains substances that do not necessarily pose health risks. The city goes above and beyond regulatory requirements, monitoring for 450+ water quality substances including basic chemistry, nutrients, bacteria, metals, disinfection byproducts, pesticides, pharmaceuticals, personal care products, hormones, and radionuclides. The vast majority of these compounds and chemicals are not detected in drinking water.
- Running several taps with cold water at full force for a short period may help flush the discolored water out of your system.
- A general recommendation is to run the taps for five minutes.
- If the water is not clear, wait for half an hour before running them for five minutes again.
