The project at hand entailed the design of a sewer extension to accommodate the expansion of the Herman Melville Museum in Pittsfield, MA. As a part of this expansion, the museum abandoned their current onsite sewage disposal system as its capacity was not large enough for the expansion. Therefore, a sewer extension was needed to tie into the public sewer system on Holmes Road. However, a conflict with the proposed sewer extension arose as there was a drainage culvert that must be crossed. Therefore, a carefully planned solution was proposed to determine the best way to extend the sewer with relocating the drainage culvert.
