Managing our water supply is becoming a bigger priority as demand for water increases. Welch Comer’s experience and capabilities provide our clients with innovative solutions for improving water supply, treatment, and distribution, while also implementing conservation programs to reduce demand.

Water is a basic necessity and water providers have both a social and regulatory responsibility to provide safe drinking water. Welch Comer understands our client’s need to meet these responsibilities and our engineering team works collaboratively with our clients to design, construct and operate safe and reliable water systems. Our depth of experience allows our staff to efficiently and effectively analyze, design, and observe construction for all aspects of a water system.
