H. Gravity sewers must be installed in front (under driveway/roadway pavement) of <br /> new buildings and/or under roadway pavement in dedicated Rights-of-Way, all <br /> accessible to maintenance equipment. <br /> I. Gravity Mains shall be installed a minimum of 10 feet from any existing or <br /> proposed structure (walls, trees, transformer pads, etc.). <br /> 14.02 WASTEWATER PUMPING STATIONS <br /> A. A Remote Telemetry Unit (RTU) shall be included in all pump stations that are to <br /> be dedicated to Indian River County. <br /> B. Wastewater pumping stations shall be designed to peak ultimate development <br /> flow from all contributory areas, in accordance with the Indian River County <br /> Wastewater Master Plan. Design average daily flow and peak hour flow shall be <br /> as set forth in Section 11.01. <br /> C. Design of private lift stations that may be dedicated to the County at a later date <br /> shall meet IRCDUS design standards and shall be approved by IRCDUS. Any <br /> private station that does not meet IRCDUS design standards will not be taken <br /> over by the IRCDUS. Owners of private stations shall sign a form acknowledging <br /> future upgrade requirements if Owner is to dedicate a private station to the <br /> IRCDUS at a later date. <br /> D. The County allows owners of single commercial properties, who wish to <br /> manage their own sewage collection on-site and transfer to the County's <br /> regional distribution collection system, to install and maintain a private lift <br /> station. The County does not permit more than one property to connect to <br /> a private lift station or private gravity sewer system, regardless if all the <br /> properties involved are owned by the same entity or not. If a developer <br /> proposes to extend sewer laterals form a private sanitary sewage <br /> collection system to other properties, then the properties must be unified <br /> as one parcel. If the properties cannot be unified, then each property must <br /> have their own private lift station, or the developer may install and <br /> dedicate to the County, a regional lift station that is constructed in <br /> accordance to IRCDUS design standards. <br /> E. At least 2 pumps shall be provided for stations handling flows of 700 gallons per <br /> minute (gpm) or less. A minimum of 3 pumps shall be provided in stations where <br /> peak design flow exceeds 700 gpm unless otherwise approved by IRCDUS. In <br /> all cases, standby-pumping capability shall be provided such that if any one <br /> pump is out of service, an alternate unit is available at equal or greater capacity. <br /> F. The sewage pump system shall be capable of pumping the design peak flow at <br /> the maximum computed system total dynamic head. Maximum residual head <br /> within existing force mains shall be obtained and coordinated through IRCDUS. <br /> G. Pumps shall be capable of passing spheres of at least 3-inches in diameter, and <br /> pump suction and discharge piping shall be at least 4-inches in diameter. <br /> 14 - 2 113.0. 3 <br />
