With engineers applying their expertise to wastewater collection, treatment, reuse, and disposal facilities, Molzen Corbin enjoys the reputation of designing water reclamation facilities that serve to return high quality water back to the region’s aquifers, rivers, and streams. We have consistently remained at the forefront of developing innovative approaches for the removal of contaminants from wastewater to meet state and federal regulations. We maintain professional and enviable relationships with the New Mexico Environment Department (NMED), Texas Commission on Environmental Quality (TCEQ), and the US Environmental Protection Agency (USEPA).
