<br />311'rl~f <br /> <br />FloGardQ1l Perk Filter System 0 & M Manual <br /> <br />Maintenance Overview for FloGard@ Perk Filter Systems <br />State and Local regulations require that stormwater management systems be maintained and serviced <br />on a recurring basis. The purpose of maintaining a clean and obstruction free Perk Filter system is to <br />ensure the system performs the intended function of the primary design. Trash and debris, floatables, <br />gross pollutants and sediment can build up in any stormwater system. This can cause the system to <br />function improperly by impeding flow in and out of the system and reducing the operating efficiency of the <br />media filters. Downstream and upstream, areas could run the risk of flooding and deleterious <br />environmental impact. <br /> <br />Recommended Frequency of Service <br />It is recommended that FloGard@ Perk Filter systems be serviced on a regularly occurring basis. <br />Ultimately the frequency depends on the amount of runoff, pollutant loading, and interference from trash~ <br />debris and gross pollutants as well as proper maintenance of upstream pretreatment devices. Howevek <br />it is recommended that each installation be inspected in accordance with the following guidelines: <br /> <br />Level 1 Inspection Service - Six (6) months after unit is placed into service, or six (6) months after a <br />Level 2 or Level 3 inspection. <br /> <br />Level 2 Inspection Service- Six (6) months after a Level 2 inspection or twelve (12) months after a <br />Level 3 service. <br /> <br />Level 3 Service - As determined by findings from Level 2 inspection service reports indicating a media <br />filter change or system repairs are required to maintain the operating efficiency of the system. <br /> <br />Service Procedures <br /> <br />Inlet Bay <br /> <br />1.
