Wastewater Collection


Wastewater is generated by residential customers, commercial businesses, industrial clients and other users in a community. If not handled properly, wastewater collection system problems can create a number of health hazards for the public, as well as pose a threat to the environment.

Wessler works with communities to solve a variety of wastewater collection system problems, such as capacity issues stemming from inflow and infiltration or undersized sewers. We provide innovative and cost-effective solutions, specifically designing sewer extensions to maximize future growth potential or rehabilitating existing sewer systems to get the most out of the infrastructure already in the ground. We implement these solutions successfully, on budget and on time.

At Wessler, our goal is to maximize efficiency for our clients by utilizing new and proven technologies in wastewater collection systems. We also are familiar with funding agencies and can provide assistance to clients in applying for project grants and loans.

No matter the size or complexity of the project, Wessler provides expert knowledge and service.
