To meet the community's future water needs, the Greeley Water and Sewer Department, with the Greeley Water and Sewer Board, have developed a long-term and comprehensive Four Point Plan, that includes increasing water conservation efforts, strengthening and maintaining Greeley 's water system infrastructure, continuing water supply acquisition, and expanding water storage.
The Water and Sewer Department is working on several large projects to help expand and enhance the water system in Greeley. These projects are part of an effort to ensure a safe, secure, and healthy water supply for the community.
Bellvue Pipeline Project
In 2003, Greeley started to build the new 60-inch diameter pipeline to transport high-quality drinking water from its Bellvue Water Treatment Plant to Greeley. The plant, which was built in 1907 north of Fort Collins, has been regularly upgraded and continues to be the primary water treatment plant for Greeley. The new pipeline will meet the existing and future water needs of our community.
To build this pipeline, Greeley conducted extensive engineering studies to determine a route that would have the least impact and would ensure that the water could flow by gravity. Gravity flow eliminates the need for expensive, power-consuming pumping facilities. Because this route goes through the cities of Fort Collins, Windsor, and Laporte, as well as unincorporated sections of Larimer and Weld counties, Greeley conducted an extensive public outreach effort to ensure that the concerns of residents and city and county government officials would be heard and addressed. Greeley is dedicated to finding solutions that are best for our community and neighboring communities. This includes ensuring that the pipeline project is cost-effective, environmentally conscious, and constructed in a collaborative fashion that takes into account the concerns of affected landowners.
Milton Seaman Reservoir: Outlet Maintenance Project
Seaman Reservoir is Greeley's drought storage reservoir. It accumulates water during wet years for use in dry years.
After more than 60 years of continuous use, the hydraulic equipment that controls the outlet gates on the Milton Seaman Reservoir must be replaced. The $1.6 million project will upgrade the 1940s hydraulic and mechanical systems on all five gates that control water levels in the Seaman Reservoir and flows to the North Fork and Poudre main stem. This project may have impacts to the river, but the city is working to minimize any effects.
Halligan-Seaman Water Management Project
The Cities of Fort Collins and Greeley propose the Halligan-Seaman Water Management Project as a regional water storage and management project on the North Fork of the Cache la Poudre River . Both cities are working together to increase water-storage capacity for their communities. Their efforts will allow them to store water during peak flow months and stock up water during wet years for use in dry years. To efficiently manage their supplies, the cities and their partners plan to develop additional storage through coordinated enlargements of Halligan Reservoir and Milton Seaman Reservoirs.
Windy Gap Firming Project
The proposed Windy Gap Firming Project achieved a significant milestone with the release of its Final Environmental Impact Statement. The project's key feature is construction of Chimney Hollow Reservoir southwest of Loveland. The project would increase the reliability of the existing Windy Gap Project, a project that started delivering water to Front Range municipalities from the west slope in 1985. The 90,000 acre-foot Chimney Hollow Reservoir would be just west of and slightly smaller than Carter Lake. Several approvals related to construction, water quality and other issues must be obtained prior to design and construction of the project.
Northern Water's Municipal Subdistrict is coordinating the project on behalf of 13 water providers. Greeley is one of the providers involved in this regional collaborative effort to increase water storage in Northern Colorado.
WPCF Aeration Improvements Project
The WPCF Aeration Improvements Project is necessary for the wastewater treatment plant to comply with anticipated (and more stringent) effluent ammonia-nitrogen discharge limits. To achieve this, the following upgrades were required:
- Increased blower capacity was necessary to supply more air to the biological treatment process.
- The existing air diffusers needed to be supplemented with additional ones to increase the aeration capacity in the existing aeration basins.
- New air supply piping was required to supply the increased volume of air to the aeration diffusers.
- Installation of new updated controls, electrical equipment (including a new backup generator), and instrumentation were required for the new aeration system.
In addition, this project will save WPCF energy. Staff is projecting about a 28% annual energy savings and a $128,000 energy cost savings due to this project. The overall efficiency for the new high-speed 300 hp K-Turbo blowers is around 72% to 74%. The overall efficiency of the replaced blowers was around 47%. Greeley will receive a custom efficiency rebate from Xcel Energy at the conclusion of project for $127,466. The new blowers are designed to meet the plant’s air supply needs through 2028.
