What we do in Colorado

Water and wastewater engineering in Golden

Golden is home to the MES Colorado office. From here we design water, sewer and site civil work across the Front Range and the mountain communities west of Denver.

We work on water and sewer lines, lift stations, small treatment plants, and grading and drainage for new sites. We also study water loss and inflow and infiltration (I&I) for small utilities.

How permitting and review works around Golden

Golden is the Jefferson County seat. Sites inside city limits go through City of Golden review. Sites in unincorporated Jefferson County go through county review instead.

The City of Golden runs its own water treatment plant, which draws from Clear Creek. The city holds some of the oldest water rights on the creek. Colorado water rights follow prior appropriation, so older rights are served first in a dry year. We cover how this meets permitting in Colorado water rights and discharge permits.

Mountain sites often rely on a small district, a well or an onsite system. Most new or expanded wastewater plants and lift stations above 2,000 gallons per day need CDPHE site location and design approval. Construction that disturbs one acre or more needs CDPHE construction stormwater coverage.

Work near Golden

MES has completed a project in the Golden area. In nearby Lakewood, we did the civil design for a six-home infill site on 0.75 acres and the grading for an outdoor learning area at a public library. In Conifer, we designed water plant upgrades and line rehabilitation for a water and sanitation district.

Common questions

Is the MES Colorado office in Golden?

Yes. Call (214) 833-6748 to talk about a project in Golden or anywhere in Colorado.

Who reviews a site just outside Golden city limits?

Jefferson County reviews unincorporated land. Water and sewer may come from a district rather than the city, so we confirm the provider first.

Does a small treatment plant in the foothills need a state permit?

A plant above 2,000 gallons per day needs CDPHE site location and design approval, plus a discharge permit if it discharges to state waters. Smaller onsite systems are permitted by the local public health agency.
