Water Well Drilling & Pump Repair in Anna, TX | DFW Well Service
Service Area Overview
Licensed well drilling and pump service in Anna, TX, targeting Collin County's Woodbine and Trinity aquifers; depth varies by parcel.
Services We Provide in Anna
DFW Well Service (TDLR License #61234 DKMPW) provides residential and agricultural water well services to customers in Anna and throughout Collin County.
Wells in the Anna area draw mainly from the Woodbine aquifer — the primary residential source across central and eastern Collin County — with the deeper Trinity Group reached where a well needs to go further. Because that transition varies by parcel, we pull driller’s logs from neighboring wells before setting a target depth, and we handle the North Texas GCD permit.

Wells around Anna draw mainly from the Woodbine aquifer — the primary residential water source across central and eastern Collin County — with the deeper Trinity Group available where a well needs to go further. There’s no single typical depth here: it depends on your parcel, which layer the well targets, and where the Woodbine gives way to the Trinity. TWDB lists both the Woodbine and the Trinity among current water sources in the Anna area, which is why we pull the driller’s logs from nearby wells before estimating depth.
Anna’s mix of longtime rural residents and newer suburban growth creates a varied customer base. Older properties may have wells dating back decades that need inspection, rehabilitation, or replacement. Newer rural homes on acreage need fresh well installations coordinated with construction timelines.
Collin County Permit Requirements
Water wells in Anna fall under the jurisdiction of TDLR and the North Texas Groundwater Conservation District. Both a drilling permit and a post-completion well report are required. The GCD enforces setback rules and monitors the aquifer to protect long-term water availability for all county residents.
