This configuration shows the reservoir upstream of the termination of the primary <br /> pipe. Reducing rings are needed in each run leg of this containment tee, <br /> necessitating additional bonding. If the rigidity of a fiberglass bonded, very <br /> compact termination is desired, this may be the preferred method. <br /> As is illustrated by these options, the versatility of the system is very good. Other <br /> configurations are certainly possible, allowing custom adaptations for specific <br /> sites. <br /> The key to the assembly of the system with the reservoir rigidly connected within <br /> the dispenser sump is using clamshell tee to contain the primary pipe or fitting_ <br /> Closing around a pipe and adapter or elbow fitting (two legs) with a tee (three <br /> legs) allows the connection of the reservoir to the open (third) leg of the tee. <br /> If there is insufficient room inside the dispenser sump, the reservoir can be <br /> located elsewhere. The connection could be with a longer, straight run of pipe, <br /> through the sump wall to the 3-inch elbow and vertical riser, or it could be <br /> through longer tube or hose connection from the dispenser sump. The reservoirs <br /> could be direct buried or located within a secondary sump, depending on the <br /> discretion of the local authorities or requirements of state regulations. A direct <br /> buried reservoir is shown in Figure 1 D. <br /> S <br /> Figure 1D <br /> Direct Buried Reservoir and Sensor in Observation Manway <br /> If the reservoirs are direct buried, an observation manway can be placed at <br /> grade level to each reservoir to obtain access for maintenance, inspection, <br /> function checks and filling. <br /> A possible configuration for the reservoirs in a remote sump is shown in Figure <br /> 1 E. If the reservoirs are located outside the dispenser sump but are put inside <br /> another sump, a cover should be placed over the sump and a manway larger <br /> than the sump cover should be used at grade level. <br /> In all cases, it is extremely important that the top of the reservoir be above the <br /> potential water table level. The top of the reservoir is not sealed so any water <br />
