Long Range Planning

The City of Greeley's utility infrastructure is part of a system of long-range planning that envisions the community's future growth and needs. This approach to integrated master planning provides the City with a defensible and coordinated Capital Improvement Plan and allows for scheduling of CIP projects to minimize impacts to citizens.  

Water Transmission and Distribution Plan 

The 2021 Water Transmission and Distribution Plan defines specific steps to provide a reliable water supply for Greeley to the years 2025, 2040 and beyond. Many components of Greeley’s water system have been in use for more than 50 and upward of 75 years and are near the end of their useful lives. In the next 50 years, demographers expect population to triple again with a corresponding increase in water demands.

Non-Potable Master Plan

Most discussions about non-potable are in reference to using untreated water for turf irrigation. This master plan addresses non-potable irrigation but is much broader in scope. It also addresses untreated water supplies and demands that are tied to water rights administration by the Water Department.

Water Conservation Plan

A new water conservation has been developed and is currently under review by the State of Colorado Water Conservation Board. The plan will be posted as soon as a version is approved by the state.

Four Point Plan

Water is a precious commodity in the state of Colorado, and it is only going to become more precious as our population grows and more water is needed. Greeley Water and Sewer is working to make sure that our community has a secure and reliable water supply, and with the leadership of the Greeley Water Board, has developed a plan to do just that. 

 It is the Four Point Plan, and through it, we ensure that our community has a safe and reliable water supply for years to come.

Improving Conservation

Greeley has a 100-year history of water conservation. Today, the conservation program is one of the largest and most successful in the state and has reduced water demand by more than 20% in recent years. It is critical that we do all we can to conserve this precious resource. Visit Greeley's Water Conservation Page for more information on programs, incentives, and events.

Strengthening Infrastructure

Greeley supplies approximately 139,638 people with up to 70 million gallons of water every day. We do this with an infrastructure of 770 miles of pipeline, two drinking water treatment plants, a wastewater reclamation plant, three treated water reservoir sites, six raw water reservoirs, and a variety of pumping stations. The system is in top shape, and we do that by:   

Continuously maintaining our system by detecting and repairing leaks and rehabilitating old pipes.

Adding new capacity to the system, such as our new 60-inch pipeline from our Bellvue Water Treatment Plant.

Constantly upgrading facilities to make them as efficient as possible, such as the new liners we recently installed to reduce leakage in our treated water reservoirs.

Continuing Acquisition

Greeley needs to add more water supply to meet our needs over the coming years, at the same time that competition for water supplies is increasing and the water is getting more expensive. We need to buy additional water now before it becomes too expensive or unavailable, and that is why Greeley works with willing sellers to purchase new water supplies for our community. 

Some developers bring water and others bring funding that the city uses to buy water for the development. Until about 1960, Greeley bought water ahead of demand. Few major water purchases have occurred since 1960, because our supply has been supplemented by development. As farms transitioned into residential and commercial areas, water from irrigated agriculture served new land uses. In the future, opportunities to acquire water in this way are very limited. To secure our water future, we need to begin buying ahead again, to be reimbursed when development occurs. 

Agricultural acquisitions have been occurring for nearly 20 years. Many farmers want to sell their water and it is from them that we are buying. Greeley leases the water back to the farmers for 10 to 20 years, allowing them to continue farming while Greeley has a secure future supply.

Expanding Storage

Water storage is needed to protect the city against drought and to hold spring runoff for use in the summer.

The cornerstone of our water storage expansion plan is with the Terry Ranch aquifer, which contains more than 1.2 million acre-feet of water and storage capacity below ground.

Greeley is a partner in the Windy Gap Firming Project. The firming project is the most effective way to provide the additional storage that Windy Gap water users need. Instead of each water provider building their own storage, the firming project takes a collaborative approach with one reservoir for all. This minimizes cost and impacts. 

Greeley has gravel lake storage and will continue to acquire more facilities. Mined out gravel pits are lined and used for water storage.
