Lake Dallas, TX Backflow Testing

Lake Dallas is a small, tightly built city on the lake's edge, and its housing stock is a mix of mid-century cottages near Main Street and newer infill closer to Swisher Road. Lots are small, so irrigation assemblies are often tucked against foundations or fences instead of sitting in an open yard box — locating the device is genuinely part of the job here. Commercial work centers on the Swisher Road and I-35E frontage: restaurants, marine and RV businesses, and small retail.

Serving older small-lot residential irrigation, Swisher Road restaurants and retail, marine and RV service businesses, and lake-adjacent properties with pumps across Lake Dallas and Denton County — about 8,000 residents.

  • Reports filed directly with Lake Dallas Public Works
  • Experienced at locating undocumented devices on small lake lots
  • No trip minimum for small-city addresses

Backflow testing in Lake Dallas: what to expect

Lake Dallas is a compact city squeezed between I-35E and Lewisville Lake, and its small lots shape the work more than anything else. Irrigation assemblies here are frequently retrofitted onto older homes and mounted wherever there was room — against a foundation, behind a fence, inside a shrub line — rather than sitting in an obvious yard box. Tracing the line from the meter forward is a normal part of a Lake Dallas visit, and it is why we ask for gate access when you book.

The commercial side runs along Swisher Road and the highway frontage: restaurants, marine and RV service businesses, small retail centers, and self-storage. Marine and automotive service shops matter more here than in a typical city this size, because wash bays, parts washers, and chemical mixing stations are high-hazard connections that need reduced pressure protection rather than the double check a landscape line would carry.

Lake-adjacent properties add the third category. When a homeowner draws lake water for irrigation with a pump, or keeps a well alongside city service, the city connection becomes high hazard. We assess that honestly on site rather than after the fact, and we file every passing Lake Dallas report with Public Works the same day.

Lake Dallas compliance, handled for you

Lake Dallas Public Works keeps the city's cross-connection records, and because many Lake Dallas devices were retrofitted after construction, the city's file sometimes lists fewer assemblies than a property actually has. We complete the state test-and-maintenance report on site and file it directly with City of Lake Dallas Public Works, then email you a copy for your records.
