Fort Collins plumbing questions
Where does Fort Collins water come from?
The Cache la Poudre River and Horsetooth Reservoir, mostly from spring snowmelt.
How much of Fort Collins' water is snowmelt?
About 80% typically comes from snowpack melting between April and July.
When should Fort Collins sprinklers be winterized?
Before the first hard freeze, by blowing out lines and protecting the backflow assembly.
How do expansive soils affect Fort Collins plumbing?
Clay soils that swell when wet and shrink when dry can shift foundations and the pipes that pass through them. Sewer laterals can sag or separate at joints, and slab plumbing can be stressed; a camera inspection before buying an older home shows whether the line has bellies or cracks.
