The term sewerimplies removal of sewageor surface runoffrather than water intended for use;[1]and the term gravityexcludes water movement induced through force mainsor vacuum sewers. Most sewers are gravity sewers; because gravity offers reliable water movement with no energy costs wherever grades are favorable. Gravity sewers may drain to sumpswhere pumping is required to either force sewage to a distant location or lift sewage to a higher elevation for entry into another gravity sewer, and lift stationsare often required to lift sewage into sewage treatment plants.", "summary": "", "title": "Stormwater Gravity Main", "tags": [], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": 0, "maxScale": 0, "spatialReference": "", "accessInformation": "As-Builts, Work Orders, Perpetual", "licenseInfo": "" }
