The feature uses points to represent data and has nine subtypes; discharge structure, junction chamber, lift station, pump station, diversion chamber, diversion point, production well, treatment plant and storage basin. A discharge structure is a building that consists of concrete box culvert that discharges sewage into a body of water or an interior drainage system. A junction chamber is a section in a sewer system where the flow from one or more sewers joins or converges into the main sewer. A lift station is designed to move wastewater from lower to higher elevation, particularly where the elevation of the source is not sufficient for gravity flow, and all mechanical components are held underground. A pump station is used to move wastewater to higher elevations in order to allow transport by gravity flow and all mechanical components are held above ground. A diversion chamber is a chamber designed to direct a stream into a channel or channels. A diversion point is a specifically named place where water is removed from a body of water by canal, pipe, or other conduit. A production well is a development well used for production of water for injection purposes. A treatment plant is where the process of removing contaminants from wastewater and sewage is performed. A storage basin is an area to store wastewater in a man-made or earthen reservoir. |
