Wastewater Treatment

At Wessler Engineering, we work closely with communities to help identify their wastewater needs and to develop cost-effective, realistic solutions. When we begin planning a project, we take into account not only the initial capital expense of the alternatives, but also the long-term operation and maintenance costs to allow our clients to make informed decisions.

We understand the many wastewater needs a community may face because we assist clients in successfully solving many of these problems. We can design and upgrade treatment plants depending on a community's need. We perform process energy audits to increase plant capacity through improved operations without spending money on capital improvements. Additionally, to ensure a successful project, our Wastewater Treatment team is also complemented by an Operations Specialist who served 12 years in the municipal sector and holds Class IV Municipal and Class D Industrial operator licenses.

At Wessler, our goal is to create efficiency for our clients by utilizing new and proven technologies in wastewater treatment. 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.
