As part of the permitting process, the U.S. Army Corps of Engineers (Corps) evaluates numerous alternatives to City's preferred alternative – the Halligan Reservoir enlargement. Other water supply alternatives studied to date require:
- Piping and pump stations
- Greater greenhouse gas emission due to ongoing pumping requirements
- Some level of pre-treatment required before water can be treated at our water treatment facility
- A higher cost per acre-foot of water
Several alternatives are evaluated in the Halligan Project Environmental Impact Statement (EIS), including:
- Enlargement of the proposed Glade Reservoir (if constructed as part of the Northern Integrated Supply Project)
- Acquisition of dedicated storage in existing agricultural reservoirs near Wellington
- Use of existing and expanded gravel pit reservoirs along the Poudre River near Overland Trail

If We Do Nothing#
Our region's semi-arid climate means the amount of water available from month-to-month and year-to-year varies, especially during dry years and drought. Without additional storage, future Fort Collins Utilities customers are vulnerable to reductions in water supply during prolonged drought or emergencies. As a result, more frequent and severe water restrictions would be likely. Fort Collins Utilities currently owns far less independent storage per customer than many other Front Range water providers.
Forest fire is just one problem that arises in times of drought. While not all are as dramatic as the 2012 High Park Fire and 2020 Cameron Peak Fire, they can have lasting impacts and effects on our region and economy. Photo courtesy of Jim Lynxwiler, Poudre Fire Authority.
Infrastructure failures can occur during a natural disaster such as a flood. Many of our neighboring communities in Northern Colorado experienced significant impacts to infrastructure during the 2013 flood. The photo above is near Lee Martinez Park.
