manhole is absent or flow volume is noticeably decreased, the situation should be <br />investigated. Possible reasons for low or no flow are lateral collapse or more likely, <br />lateral blockage due to soil or sediment. Each of the three laterals entering the affected <br />manhole will need to be visually observed to determine which one(s) are blocked. If <br />pipe blockage is identified, the lateral can be power jetted to remove sediment buildup. <br />Power jetting or rodding should be done from the east end of the lateral, and the <br />influent and effluent header pipe at the manhole in which the rodding is taking place, <br />should be temporarily plugged. Any sediment should be pumped out of the manhole. <br />Removed sediment should be disposed in the landfill, and leachate/backwash water <br />should be pumped to a downstream manhole, or to the leachate pump station. <br />The Indian River County Utilities Department is responsible for maintenance of the <br />leachate pump station, meter, forcemain, and other onsite lift stations. They maintain <br />the float system for pump control, the electrical system, submersible pumps, and valves. <br />A flow meter has been installed on the discharge line from the leachate pump stations. <br />The Utilities Department shall insure that the leachate flow meter remains calibrated <br />and is in proper operating condition at all times. Leachate flows shall be read daily <br />with the amount of leachate recorded by landfill personnel. This will allow <br />determination of leachate production as a function of rainfall, and provide information <br />to assess the efficiency of cover and stormwater management practices. The monthly <br />leachate flow shall be reported with the monitoring facility report. Leachate <br />generation/flow records shall be kept at the landfill as part of the official operation <br />record. <br />If leachate volume exceeds the 190,000 gallon per month average flow limit, the SWDD <br />will have the option to purchase additional capacity at the subregional wastewater <br />F-17 <br />1 <br />0 <br />0 <br />a <br />0 <br />e <br />1 <br />0 <br />vvr <br />
