Sanitary Sewer Design

Though we take them for granted sanitary sewers tend to be the defining element of the developability of land. For reasons of public health, sanitary sewers are generally the deepest buried utility element in a development. Because, short of installing lift stations, sewers are designed for gravity flow, the depth of the nearest connecting point defines the maximum depth of the sewers, which in turn impacts other utilities that need to cross the sewer. Varying minimum slope requirements, spacing of manholes to accommodate cleanout, and accessibility concerns amongst municipalities also affect design.

Preliminary design of sanitary sewers is often one of the steps undertaken by Landplan Engineering to assist Clients in identifying the feasibility of a development, identifying potential connection points and the means of connectivity (gravity, lift station, or small scale wastewater treatment). Landplan assesses site grading issues and future connectivity to additional phases of development to generate cost-effective solutions. These solutions balance maximizing the developable area within a site while minimizing the length and complexity of the system of sewers to be installed. Design services are often accompanied by regulatory assistance with permit applications and filings for extension of sanitary sewers.
