The City of Plainview runs 16 public water supply wells and a treatment plant for water from the Canadian River Municipal Water Authority, whose supply comes from Lake Meredith and Ogallala Aquifer wells in Roberts County. Hardness varies with the blend, so test your tap before sizing a softener, and consider reverse osmosis at the kitchen sink for drinking water.
Permits run through the city's Building Permits and Inspections office at 202 W. 5th Street. The city lists new and remodeled homes, roof replacement, room additions, decks more than 32 inches high, retaining walls over 48 inches, HVAC work, new electrical circuits, plumbing changes, and wall removals among the work that needs a permit. It publishes separate residential applications for building, electrical, mechanical, plumbing, and roofing permits, plus checklists for new construction, remodels and additions, and re-roofing.
