<br />. <br /> <br />. <br /> <br />. <br /> <br />III. <br /> <br />City of Arden Hills <br /> <br />SANITARY SEWER IMPROVEMENTS <br /> <br />A. Definitions <br /> <br />1. Sanitary Sewer Interceptors <br />A network of relatively large diameter, deep sewer pipe and associated <br />pumping stations and appurtenances. The interceptors are designed as <br />collectors for large areas within the sanitary scwcr service area. <br /> <br />2. Sanitary Sewer Trunks and Subtrunks <br />Sanitary sewer pumping stations, including associated forcemain and/or a <br />network of gravity pipes ranging in size generally from ten inch (10") <br />through eighteen inch (18") and extending away from respective <br />interceptor mains. Pumping station, forcemains, trunks and subtrunks are <br />designed as collectors for areas usually less than three hundred (300) <br />acres. Because sewer lines flow by gravity, the pipes can become quite <br />deep at some locations and very costly to install. A trunk or subtrunk <br />assessment is, in certain cases, utilized so that costs due to extra depth <br />(and/or oversizing) will be spread over the entire service district rather <br />than becoming a burden on just those properties abutting that portion of <br />the pipe network constructed. <br /> <br />3. Sanitary Sewer Laterals <br />A network of pipes, usually eight inch (8") in size that are installed eight <br />(8) to twenty (20) feet deep and are designed to serve those buildings <br />abutting a given street or easement. The laterals drain to trunks, subtrunks <br />or directly to interceptors. <br /> <br />4. Sanitary Sewer Building Services <br />Those pipes, usually four-inch (4") or six-inch (6") in size leading from <br />laterals (or sometimes from trunks, subtrunks and interceptors) that serve <br />individual buildings. The services are plugged at the property line until <br />such time that a building is connected to the sewer system. The property <br />owner must make arrangements with a licensed, bonded plumber to <br />complete the service connection. <br /> <br />5. Sanitary Sewer Availability Charge (SAC) <br />This is a charge billed to all properties at the time of connection to the <br />sanitary sewer system. The charge is the individual property share of the <br />cost of the interceptor trunk and treatment facilities that make sewer <br />service available. The charge is based on an equivalent unit basis. The <br />method used to calculate the total number of units for any specific <br />property and the current unit charge are based on the Metropolitan Council <br />Environmental Services (MCES) for expected sewage flow from various <br />dwellings or businesses. A listing of the MCES sewer availability charges <br />is available on the Metropolitan Council website: www.metrocouncil.org <br /> <br />2003 Assessment Policy Manual - Page 7 <br />
