Sewer and Water Line Service in Westminster, CO

Westminster spans two counties and decades of very different construction, which makes it one of the more varied cities in the metro underground. The older sections near the original town core and the postwar tract neighborhoods built from the 1950s through the 1970s carry Orangeburg and cast iron sewer laterals along with galvanized steel water services, while later growth through the 1980s and 1990s shifted to cast iron and early PVC, and the newest development toward the Adams County side of town is almost entirely PVC and copper or PEX.

The postwar tract sections of Westminster follow the same pattern seen in Northglenn and Thornton, since all three cities absorbed the same wave of rapid Denver-area suburban growth in roughly the same construction period. Orangeburg deforms and collapses under years of soil load, and galvanized service corrodes from the inside until pressure loss becomes the primary symptom rather than an obvious leak.

Because Westminster crosses the Adams and Jefferson county line, the water and sanitation authority for a given address is not always obvious from the surrounding development alone. Two neighboring subdivisions built in the same decade can be served by different water providers depending on which side of the county line they fall on, and confirming that authority is one of the first steps on any Westminster project.

Denver Sewer and Water works across both sides of Westminster, from the older postwar tract core to the newer development near the city's edges. We scope the line first, we confirm the correct permitting authority for the address, and we handle the coordination rather than leaving it to the homeowner to sort out.
