Drinking Water

The City of Longmont produces an annual Water Quality Report which provides information about Longmont's drinking water and the results of thousands of tests performed on the water during the year. View the report and learn more >

Stormwater Quality

The Storm Drainage System does not include any treatment system. So, any litter, sediment or pollution on the ground has a potential of getting washed into the storm drain and into our rivers. Learn about our Stormwater Quality Program, including how to clean up small spills, prohibited discharges and the Keep It Clean Partnership. Visit the Stormwater Quality Program webpage >

Watershed Protection

In addition to our drinking water, our watershed provides homes to wildlife and amenities to residents. Find out how the City of Longmont monitors and protects the watershed.
