<br />. <br /> <br />fit <br /> <br />CHAPTER 4 <br />SANITARY SEWER DESIGN REQUIREMENTS <br /> <br />4.01 CHAPTER INCLUDES <br /> <br />A. Criteria for the design of sanitary sewer systems. <br />B. This chapter addresses the design of the sanitary sewer systems to be located within the <br />public right-of-way or a dedicated public easement. Sanitary sewers located on private <br />property, that are not in a dedicated public easement, shall not be considered part of the <br />publicly maintained sanitary sewer system. <br />C. On a case-by-case basis the City of La Porte reserves to the right to allow deviations from <br />these design criteria where necessary. These design criteria are not intended to cover <br />repairs to pre-existing facilities especially when such repair work is performed by City of <br />La Porte personnel/forces. These criteria are not intended to cover existing sanitary <br />sewer facilities located in alleys or other areas that do not conform to these criteria. <br /> <br />4.02 DEFINITIONS <br /> <br />A. Public Sanitary Sewer - All sewers that are maintained by the City of La Porte and <br />located in public easements or street rights-of-way, pre-existing sanitary sewer lines that <br />are serving the public at the time of the adoption of these regulations, and new sanitary <br />sewers that are installed in accordance with these standards. <br />B. Sanitary Sewer Main - A sewer which receives the flow from one or more lateral sewers. <br />C. Lateral Sewer - A sewer running laterally down a street, alley or easement which <br />receives flow from abutting property. <br />D. Service Lead - A sewer which branches off of a public sewer and extends to the limits of <br />the public right-of-way. It shall be construed as having reference to a public sewer <br />branching off from a main or lateral sewer to serve one or more houses, single family <br />lots, or other types of small land tracts situated in the same block, but not directly <br />adjacent to the main or lateral sewer. A service lead shall never exceed 60 feet in <br />perpendicular length from the intersecting sewer main or lateral. If the sewer is designed <br />to serve more than two houses, or the equivalent of two single family residences along a <br />street, a lateral sewer as defined above shall be constructed. <br /> <br />4.03 DESIGN REQUIREMENTS <br /> <br />A. Drawings to be Furnished <br /> <br />1. Before any sanitary sewer main or lateral sewer is constructed and before the <br />City will approve any proposed sanitary sewer for construction, plan-and-profile <br />sheets of the proposed sanitary sewer shall be prepared and submitted to the City <br />for approval. <br />2. These drawings shall become the property of the City of La Porte. <br />3. Drawings shall include at a minimum layout sheets with contours, plan-and- <br />profile sheets, and details sheets for special items. <br /> <br />B. Details to be Shown on Drawings: <br /> <br />1. The construction drawings shall show at a minimum the exact location of the <br />proposed sanitary sewer in the right-of-way, alley, or public easement with <br />respect to the edge of the particular right-of-way, survey base line, any nearby <br />utilities, 100-year floodplain elevation within the project area, major <br /> <br />Sanitary Sewer Design Criteria Page 1 of 11 <br />
