cd. Sewer collection lines shall be designed to flow half full and have velocities of two (2) feet per second or have a minimum slope as approved by the Louisiana Department of Health and Human Resources.
de. Lift stations shall be designed with a minimum of two (2) pumps and each pump shall be capable of pumping three (3) times the average flow of one hundred (100) gallons per capita per day. All sewer lift stations shall be three (3) phase 230-volt design.
ef. House connections shall be a minimum of six (6) inches in diameter and shall be installed by the developer from the collection line to the property line of each lot. Individual service lines sealed with a plug shall be provided for each lot located on the side of the street upon which the sewer main is located and a single line crossing the street with the use of a wye is permitted to service two lots. The minimum cover at the end of each sewer service line shall be thirty (30) inches with a maximum of forty-eight (48) inches above the edge of the roadway or top of curb where curbs are proposed (unless approved otherwise in writing on a case by case basis by the Director of Public Works/Wastewater to address special situations). "H/C" shall be stamped in curbs and sewermarkers (which shall be submitted to the Parish for review and approval) shall be placed 12 inches off the edge of roadways without curbs, and shall be located perpendicular to the lots sewer house connection in straight roadways and radial to the lots sewer house connection in curved roadways.

A 4" minimum diameter schedule 40 white PVC pipe shall be installed immediately in front of the house connection plug and shall extend no less than twenty-four (24) inches and no more than forty-eight (48) inches above the nearest edge of the roadway when curbs are not to be utilized or the nearest top of curb when curbs are to be constructed.
