The unique Triangular Ribs are unparalleled in ability to resist vertical and horizontal ground pressure. The series of short, flat, triangular surfaces keeps the direction of the forces in line with each rib, thus substantially increasing stiffness compared with curved ribbed tanks. In curved ribbed tanks, approximately 50% of the curved wall surface area is capable of resisting vertical loads, whereas 100% of the wall surface area of Triangular Ribs contributes to the load bearing capacity of the tank.
Material: High density linear polyethylene (safe for food contact-water tanks). Meets FDA regulations 21 CFR 177.1520(C) 3.1 Wall thickness - 0.35" +/- .03". CSA and ANSI/NSF61 approved.
Plumbing: Septic tanks are pre-plumbed with 4" solvent weld PVC pipe connections, Tee Y's, dip tubes and inspection plugs to local plumbing codes. (No plumbing in water cisterns.)
Partition: Rigid 1-+" thick plastic board. (Optional in some locations.)
Access Lids: Two nom. 24" dia. Heavy duty molded polyethylene. Each lid safety secured with 6 corrosion resistant screws. NOTE: Cistern tanks may be sealed watertight with silicone sealant under lid.
Risers: Risers for direct access from the ground surface fit over man way lids on the tank. Riser base must be lag screwed and glued to top of tank. An additional lid on the riser provides additional safety and security. (Lid on tank should remain in place for structural integrity.) See separate sheet for risers. Tanks accommodate 24" dia. Polylok and UltraRib risers.
Water Table: Maximum allowable - 1' above water level in tank to limit deflection in tank base. (Install dip tube on outside of tank.)
Installation: Maximum dirt cover above top of tank - 4 ft. Use GRANULAR BACKFILL ONLY. Remove rocks from tank surface, compact evenly underneath and around tank. Lids must be secured in place when backfilling. Use extra heavy weight, two chamber tank in wet soils. NO WATER NEEDED IN TANK WHEN BACKFILLING. Refer to full installation instructions. CSA dead load test - 25,000 lbs.
Warranty: Premier Plastics below ground tanks are warranted for 10 years against defects and degradation in the material. (See full warranty sheet).
