About Wastewater Treatment

We believe our company’s success in wastewater treatment is due in part to the fact that our principals are heavily involved in projects from conception through completion. For many projects, the principals serve as the technical leaders, providing direction, reviewing work, and assisting in making decisions. At Plummer, we typically seek input from clients prior to setting direction, rather than relying on client reviews, which helps promote a truly collaborative effort and leads to better facility designs. Our wastewater treatment team conducts performance evaluations, provides master plans, assists with process and equipment selection, brings facilities into compliance, and provides start-up assistance, operator training, and troubleshooting. 

Whether designing a new treatment facility or upgrading an existing one, we help address issues related to growth, optimization, aging infrastructure, and regulatory compliance.
