Wastewater Collection

Wastewater is generated by residential, commercial, industrial and other users in a community. If handled improperly, wastewater can create a number of health hazards for citizens, as well as a number of environmental concerns.

We work with clients to solve a variety of wastewater collection system problems, such as capacity issues stemming from undersized gravity or low-pressure sewers, or inflow and infiltration. We provide cost-effective solutions, specifically designing sewer extensions or rehabilitating existing sewer systems. We implement these solutions successfully, on budget, and on time.

At Wessler, our goal is to create efficiency for our clients by utilizing new and proven technologies in wastewater collection systems. No matter the size or complexity of the project, we provide expert knowledge and service. We are also familiar with funding agencies and can provide assistance to clients in applying for project grants and loans.
