Pressure Washing in Westminster, CO

Pressure Washing in Westminster happens upstream of the city's creeks and lakes. According to the city, rain and snowmelt north of 92nd Avenue drain to Big Dry Creek, everything south of 92nd drains to Little Dry Creek, and storm drains run directly to waterways that include Standley Lake. Nothing in that path treats the water first, so soap and grime rinsed off a driveway can travel straight into a creek.

Storm sewer versus sanitary sewer

Westminster explains the difference plainly: sanitary sewers carry household wastewater to a reclamation facility for treatment, while the storm sewer collects runoff from storms and irrigation and sends it to creeks, rivers and lakes untreated. That is the reason we stop rinse water short of the gutter, keep detergents on the property, and steer rinse water toward lawn or mulch beds where it can soak in.

Why nutrients matter here

The city notes that runoff picking up fertilizer, pet waste and other pollutants adds excess nutrients to local water, which can feed algae growth that robs fish of oxygen. We apply only as much cleaning solution as a surface needs, rinse carefully, and avoid washing debris such as leaves and grass clippings into the street.

A century of building styles

Westminster's first permanent settler farmed near what is now West 76th Avenue and Lowell Street starting in 1870, and the town incorporated in 1911. Westminster University's original building was made of red sandstone quarried in the Red Rocks area. Over the following century the city spread north toward 144th Avenue, so house ages and materials vary widely. Natural stone, older brick and painted wood get low pressure and gentle detergents; newer vinyl, stucco and concrete get their own settings.

Hillside lots and runoff paths

Westminster's trail system follows corridors such as Big Dry Creek, Walnut Creek and the Farmers' High Line Canal. If your lot slopes toward a greenbelt, trail or creek corridor, rinse water picks up speed and can carry grit downhill before it soaks in. On a sloped lot, we look at where water will travel before the hose comes out, place barriers or absorbent socks along the low edge, and wash from the top down so no section gets rinsed twice.

Drought watch and water use

In 2026 the city reported one of the hottest and driest winters on record and an exceptionally low snowpack, and it placed Westminster under a Drought Watch with a voluntary guideline to water turf no more than three days a week. We plan cleaning to use water efficiently, shut off between sections, and keep runoff on site. If the city moves to a stricter stage, we review the new rules before scheduling and adjust the plan, or the timing, to fit them.
