Pullman Conserves



As the first year of the newly established Outdoor Irrigation Season comes to an end, residents are reminded that the season will conclude as scheduled on September 30, 2023. The Pullman City Code Chapter 10B for Water Conservation outlines the Outdoor Irrigation Season as June 1 through September 30 annually, unless otherwise declared by the Public Works Director or their designee. Outside of this time frame, outdoor irrigation is prohibited. However, handheld watering is always permitted when an individual is present.

After City staff evaluated soil conditions and forecasted weather, it was determined that circumstances do not necessitate a variation to the scheduled end date of Septembr 30 for the 2023 Outdoor Irrigation Season.

The Outdoor Irrigation Season, defined in the Pullman City Code, was established earlier this year in order to support responsible water usage and conservation as well as help to slow the depletion of the Grande Ronde aquifer, the City’s sole drinking water supply source. Nearly one-third of the total water used each year in Pullman is attributable to outdoor use, primarily landscape irrigation.

Thank you to Pullman residents for doing their best to conserve water during this first Outdoor Irrigation Season. The City of Pullman is focused on education and empowerment first and foremost by working closely with our community. Please send any questions or feedback via email to [email protected].

Water conservation can be effectively practiced throughout the year.  Sweep patios, driveways, and sidewalks instead of hosing paved surfaces. If you are still watering your plants, lawn, and garden, remember they require less water as daylight hours and temperatures decrease.

Every Drop Counts
Nearly one-third of the total water used each year in Pullman is attributable to outdoor use, primarily landscape irrigation.

Pullman City Code, Chapter 10B (Water Conservation) aims to decrease outdoor water use and facilitate water conservation in the warmer months, through the development of an irrigation management plan. The code establishes an Irrigation:
Season - June 1 to September 30. Outdoor irrigation shall be prohibited at all times not within the Outdoor Irrigation Season. 
Schedule - assigned watering days based on even-odd addresses
Watering Window - opens at 6 PM and closes at 10 AM the following day

There are automatic exemptions in place for various construction and home maintenance activities. These guidelines are for outdoor irrigation only. For example, running through the sprinkler is considered recreating, and therefore is not subject to the parameters identified. Similarly, washing a vehicle at your home is not subject to the irrigation guidelines.

Handheld irrigation, while someone is physically present is ALWAYS allowed, and not subject to the irrigation season, schedule, or watering window.

NEVER should a hose, or another water source, be left running, allowing water waste or irrigation water to be applied to non-landscaped spaces.

Water Conservation Incentive Programs

Conservation LogoApply for any of the water conservation rebates or credits offered by submitting a complete Water Conservation Rebate Application. The application includes instructions and  details on the requirements to qualify for the various rebate and credit opportunities. Submitting the application before any work is done is required. All rebates offered require an initial inspection as part of the approval process.

The rebate process cannot begin until a complete application has been submitted and processed.
A review of the existing fixtures or irrigated lawn space by City staff must occur prior to any work being done. Anything altered and/or removed prior to application for the program and prior to inspection will not qualify for a rebate.

Toilet Rebates
The City’s toilet rebate program launched in 2008. Since that time Pullman property owners have replaced over 2000 toilets resulting in an estimated annual water savings of 8.4 million gallons of water per year. In 2015 the City’s toilet rebate program was expanded to include five different types of toilet rebates including a rebate for new construction.

In an effort to encourage water conservation, the City of Pullman offers rebates to water customers that replace old, higher flow toilets, in favor of new low flow versions. Rebates of up to $125 are available!
Typically, toilets made before 1994 use 5 to 7 gallons per flush. Today there are many low flow options such as an Ultra Low Flush Toilet (1.6 gallons per flush) or a High Efficiency Toilet (1.28 gallons per flush, or less). Switching over one toilet can save as much as 10,000 gallons per year, and through our Toilet Rebate Program it is economically advantageous to switch. To qualify for the rebate, an applicant must be the owner of a residential or commercial property served by the City of Pullman Water System and be replacing your existing pre-code toilet with either a new Ultra Low Flush or a High Efficiency toilet. In order to receive the rebate, applicants must first complete a Water Conservation Rebate Application. Once the application is processed one of our Operations Technicians will perform an onsite inspection of your existing toilet in order for your application to be approved. Once the new lower flow toilet is installed, a second inspection will take place, followed by your rebate being processed and issued through our Finance Department.

The Water Conservation Rebate Application is available online, or can be obtained from the Public Works or Finance Departments in City Hall at 190 SE Crestview St, Bldg A, Pullman, WA 99163 For additional information please call (509) 338-3243.
Lawn Removal Credits
As the City of Pullman strives to continue meeting and exceeding conservation goals, a $150 credit is offered to any water system customer that removes at least 300 square feet of lawn in favor of drought resistant plantings. The process to claim the credit is simple. Begin by filling out our Water Conservation Rebate Application and a representative will contact you to perform an onsite inspection of your existing landscape, and to discuss your project. Following the initial inspection, simply complete the project and contact us at (509) 338-3243 for a final inspection. It is a great way to update your landscaping while saving both money and water.
Washing Machine Rebates
Owners of multifamily housing facilities with common area laundry facilities can receive a $200 rebate to replace existing non-efficient washing machines with newer Energy Star compliant washing machines. It is a great way to update your older non-efficient washing machine while saving both money and water.
