As one of the fastest-growing cities in the country, San Antonio puts more pressure on its underground systems every year. LSEC delivers the wastewater and stormwater infrastructure services San Antonio depends on to keep the region running.
24/7San AntonioSAWS-AreaGrowth CorridorGrowth this fast does not wait, and neither do the systems running beneath the city. Every new development, every added connection, and every aging line pushes San Antonio’s infrastructure harder.
Municipal utility, industrial facility, commercial property, or active construction site, LSEC brings the equipment, crews, and local knowledge to get it done right.
Few markets ask as much of a contractor as San Antonio. The region sits atop the Edwards Aquifer, a protected and environmentally sensitive water source, which means the work has to be done right and done clean.
Add in one of the state’s largest water utilities, a major military presence across Joint Base San Antonio, and relentless growth pushing new infrastructure outward, and this market rewards local knowledge while punishing guesswork.
Our teams understand these systems, the regulatory landscape, and the urgency that comes with keeping a city like San Antonio running.
Across the region, LSEC delivers the underground infrastructure services municipalities, utilities, contractors, and facilities depend on.
