TECHNICAL STORMWATER MANAGEMENT W TAN K R_TANK OPERATION, INSPECTION & MAINTENANCE Operation Your ACF R-Tank System has been designed to function in conjunction with the engineered drainage system on your site,the existing municipal infrastructure, and/or the existing soils and geography of the receiving watershed. Unless your site included certain unique and rare features, the operation of your R-Tank System will be driven by naturally occurring systems and will function autonomously.However,upholding a proper schedule of Inspection&Maintenance is critical to ensuring continued functionality and optimum performance of the system. Inspection Both the R-Tank and all stormwater pre-treatment features incorporated into your site must be inspected regularly. Inspection frequency for your system must be determined based on the contributing drainage area, but should never exceed one year between inspections (six months during the first year of operation). Inspections may be required more frequently for pre-treatment systems. You should refer to the manufacturer requirements for the proper inspection schedule. With the right equipment your inspection and measurements can be accomplished from the surface without physically entering any confined spaces. If your inspection does require confined space entry,you MUST follow all local/regional requirements as well as OSHA standards. R-Tank Systems may incorporate Inspection Ports, Maintenance Ports, and/or adjoining manholes. Each of these features are easily accessed by removing the lid at the surface. With the cover removed, a visual inspection can be performed to identify sediment deposits within the structure. Using a flashlight,ALL access points should be examined to complete a thorough inspection. Inspection Ports Usually located centrally in the R-Tank System,these perforated columns are designed to give the user a base-line sediment depth across the system floor. Maintenance Ports Usually located near the inlet and outlet connections,you'll likely find deeper deposits of heavier sediments when compared to the Inspection Ports. Manholes Most systems will include at least two manholes-one at the inlet and another at the outlet. There may be more than one location where stormwater enters the system,which would result in additional manholes to inspect. Bear in mind that these manholes often include a sump below the invert of the pipe connecting to the R-Tank. These sumps are designed to capture sediment before it reaches the R-Tank, and they should be kept clean to ensure they function properly. However, existence of sediment in the sump does NOT necessarily mean sediment has accumulated in the R-Tank. After inspecting the bottom of the structure, use a mirror on a pole(or some other device)to check for sediment or debris in the pipe connecting to the R-Tank.
