Is there a list of septic companies in Lavon, TX?

Septic companies serving the Lavon, TX area.

Lavon is a city in Collin County and has been one of the U.S. state of Texas's fastest-growing communities: from a 2000 census population of 387 and 2020 tabulated population of 4,469, Lavon is now part of the Dallas-Fort Worth metropolitan area.

Like Allen and Anna, Lavon's septic permitting runs through Collin County Development Services in McKinney (4690 Community Ave., Suite 200, phone 972-548-5585); the county requires three passed inspection reports from a private third-party inspector before it will release power to a new system.

Lavon sits about a mile southeast of Lavon Dam on the East Fork of the Trinity River, which forms Lavon Lake, a key recreational and water-supply resource for the region. The city covers about 2.4 square miles at an elevation of roughly 518 feet, in the 75166 ZIP code, and the area codes here are 214, 469, 945 and 972.
