Durango water treatment built for the Animas Valley

For more than 40 years, Water Works has treated water across Colorado — and the Animas Valley is one of the places we work most. Durango's water comes from wells, from the river, and from aging plumbing, and the treatment that actually works here is the treatment designed around what your specific source delivers.

The Western Slope water story

Why Durango water needs to be tested — not assumed

Durango sits in a river valley surrounded by mountains and ranchland — which means most of the water here either comes out of the ground or out of a faucet that has traveled through some pretty varied plumbing. Both have their own characteristic problems.

Private wells in the Animas Valley commonly test high for hardness minerals, iron, and manganese, with arsenic and nitrates appearing often enough to matter. Municipal customers aren't off the hook either: disinfection byproducts form in the distribution system, and lead and copper can leach from older galvanized or brass plumbing inside the home.

A treatment system designed for someone else's water almost never fits yours. We start every Durango job with a real on-site analysis and design from the results.

How Water Works helps

Treatment designed around what your water actually contains

For most Durango homes, the right answer is a layered system: a softener at the point of entry to handle hardness and protect appliances, plus a reverse osmosis unit or under-sink filter for the kitchen tap where you actually drink and cook. Wells with iron, manganese, sulfur, or arsenic usually need a pre-filter ahead of the softener. Municipal customers with chlorine-taste concerns often pair a softener with a small carbon polishing filter.

We design the system, install it, and verify the treated water meets the mark at every tap it's used. Then we come back: well water should be tested at least once a year, and we keep your system serviced and your water verified season after season.

Durango water treatment FAQs

Is Durango's tap water safe to drink?

Municipal water in Durango is treated and tested, and the Animas River supply is generally reliable. But 'safe to drink' and 'good to drink' aren't the same — hardness, chlorine byproducts, and trace metals from aging household plumbing can still affect taste, smell, and long-term exposure. The only way to know what's actually coming out of your tap is to test it.

What contaminants are most common in Durango well water?

Western Slope wells commonly pick up hardness minerals, iron and manganese, arsenic, and elevated nitrates from agricultural runoff. Depending on location, we've also seen lead leached from older galvanized plumbing, sulfur-reducing bacteria, and the disinfection byproducts chloroform and bromodichloromethane. A real water analysis tells you which of these yours has — guessing isn't a strategy.

How often should I test my water in Durango?

At least once a year for a private well — more often if you've ever had a positive result, if your area has known issues, or if your water changes in taste, smell, or color. After wildfires, flooding, or any work on the well or plumbing, test before you drink it. Municipal customers in Durango should test at the tap every few years to catch plumbing-related contamination the utility doesn't see.

Do Durango homes really need a water softener?

Hard water is the rule in the Animas Valley, not the exception. You'll see it as spotting on glassware, scale on faucets and shower glass, and shortened lifespans for water heaters and dishwashers. A softener isn't luxury — it's the difference between appliances that last 15 years and ones that last 6. Salt-free conditioners help with scale too, but they don't actually remove the minerals.

Can you service my home if I'm outside the city of Durango?

Yes. Water Works covers the Animas Valley, the La Plata County area, and the surrounding Western Slope communities — Bayfield, Ignacio, Mancos, Cortez, and beyond. Our four regional offices dispatch across the region, and on-site well testing and system installation are routine work for our service techs throughout the Western Slope.
