Wastewater

Increasingly stringent water quality requirements demand improved wastewater treatment techniques to protect our water resources. Welch Comer utilizes both state of the art technology and classic solutions to provide our clients with cost effective wastewater systems.

Wastewater systems can be challenging to design, construct, and permit. Our experience with planning and designing wastewater systems and our reputation and relationship with regulatory agencies allows our staff to efficiently design and permit wastewater projects. Welch Comer wastewater designs include sewer collection lines, lift stations, and wastewater treatment systems, such as recirculating gravel filter systems, to award winning membrane bio-reactors that produce Class A wastewater suitable for human contact.
