West Penn and Walker Townships required an Act 537 sewage facility plan update. The previous engineering firm for the Townships prepared an update study over the course of four years, but the Pennsylvania Department of Environmental Protection (PA DEP) deemed it incomplete. The Townships wanted RETTEW to complete the study, incorporating as much of the previous information as possible.

RETTEW negotiated with PA DEP to accept a new scope of work to use completed components of the prior study and allow us to complete any deficient aspects of the study. Our team developed alternative solutions for the project that saved the Townships almost $8 million in design and construction costs, as well as lower projected annual operations costs. RETTEW evaluated the original needs assessment study to determine if the large public project was really necessary at this time, thereby delaying the implementation cost until growth warrants the public sewage facilities in the future.
