IND ,o-oi%'. Optional PI3r'hg Sumps Models PS42.22S, PS42-308, SPS42.22A, SPS42-30A For Secondary Contain- ment of Pumps 8 Piping The piping sump provides containment of a submersible pump leak and also provides a termination point for double- wall piping systems. The piping sump is constructed of fiberglass—a proven mate- rial for long-term performance— and features a 30 year struc- tural and corrosion warranty. Compared to other unreinforced plastics, the rigid fiberglass construction minimizes piping sump deformation during back- filling to assure liquid -tight seals at side and bottom penetrations. Tanks and piping sumps are shipped together for improved jobsite logistics, which mini- mize jobsite delays and cost over -runs. The piping sump is installed on top of the manway cover where the submersible pump is located. Primary piping is installed from the submersible pump to the dispenser. When the double-wall piping is installed over the primary piping, the double-wall pipe connects to one of the two factory installed fittings in the side of the piping sump. In the event of an accidental spill from the primary piping, the f iNed product will drain to the piping sump. Any spill from the submersible pump is also contained by the piping sump. All of the piping sump cr. ation s, which are used for electrical and piping Veft- nections, can be sealed to provide a "watertight" con- tainer. A friction fit lid (Model Series PS) prevents rain water from entering through the top of the piping sump. Since the top is not sealed, the piping sump will fill with water if the groundwater table exceeds the top of the piping sump. As an option, the piping sump can be specified with a bolt -on gasketed lid (Model Series SPS) to provide an "airtight" container which can be used in areas with high ground- water conditions or where the owner wants to test the tightness of the secondary piping and sump. O/C Tanks recomn)ends con- tinuous electronic monitoring to warn the tank operator of an excessive accumulation of petroleum product in the piping sump. An optional piping sump sensor for continuous electronic monitoring is available. This sensor is compatible with the optional O/C Tanks supplied electronic control panels. The piping sump is available with either a 22" ID or 30" ID manway bolt pattern. To maximize tank anchoring safety factors when the tank is not mechanically anchored, fill the piping sump with gravel. If gravel is not used to fill the piping sump, a maximum of two piping sumps (or one piping sump and one unfilled manway riser) may be used with tank sizes 10,000 gallon capacity and larger. Only one unfilled piping sump (or one unfilled manway riser) is per- mitted with tank sizes less than 10,000 gallon capacity due to possible buoyant forces. completed Piping Sump Installation with Optional Sump Sensor S„ g., Foam Board Fittings for electrical connections .-- Piping sump.. diem installed) Turbine" 3" FRP bell coupling Primarypipe-- .Junction box" Optional piping Double wall sumpsensor- pipe* • I 'Optional sump sensor kit is available from Owens-Corning "Contractor supplied items New Extra reinforcement required above piping sump: M5 rebar B" on center both ways (2 layers), additional reinforcements extend 4'm all directions from the center of the piping sump.
