Abstract:

During extended periods of wet weather and storm events, large volumes of groundwater and surface water can infiltrate typical sanitary collection systems, resulting in design requirements to oversize the piping network. Affordable and cost-effective sewage collection systems that maintain or improve environmental protection are often sought out by municipalities and design engineers; however, traditional gravity sewers typically allow excessive amounts of infiltration and inflow (I/I) to enter into the sewer network, overwhelming the treatment plant with surges of diluted sewage and leading to requirements for bypass of the treatment process. The evolution of the small diameter variable gradient (SDVG) sanitary collection system into the watertight Small Bore Sewer^™ (SBS^™) system has proven that removal of inflow/infiltration and removal of sewage solids at source can eliminate bypass occurrences and reduce the downstream wastewater treatment plant requirements and operation and maintenance costs.
