Richardson sits at the northern edge of Dallas County, straddling the line into Collin County. It is a fully developed city, and it is important to be honest about the geology: nearly everyone here is on treated surface water from a municipal system, and a private well is the exception, not the rule.
The reason is depth. There is no shallow water-table aquifer under this area. The first usable unit, the Woodbine, sits roughly 600 to 1,500 feet down; its upper zone runs high in iron and manganese, and its water grows increasingly saline below about 1,500 feet. The Trinity sands that produce reliably — the Paluxy, Glen Rose, and Twin Mountains group — are deeper still, on the order of 2,000 to 3,500-plus feet, confined and far below ordinary residential drilling. TWDB monitoring wells in the Dallas County Twin Mountains are documented at 2,568 and 3,076 feet. A well here is a deep, serious project, and on nearly every Richardson lot municipal water is the better answer.
Dallas County Permit Requirements
Dallas County has no groundwater conservation district, so well construction follows TDLR statewide standards rather than a local district permit. No GCD permit is required, but your driller must hold a current TDLR license, the well must meet the Texas Well Construction Standards, and a completion report must be filed with TDLR after the work is done. See our guide to Dallas County water well regulations for the details.
Because productive water sits so deep here, we do not quote a flat per-foot rate without seeing the property, and we will tell you honestly if a well is not the right call. Call DFW Well Service at (940) 536-8560 for a free written estimate on any well or pump project in Richardson or Dallas County.
