B. Loading Conditions 1. When installed according to the manufacturer’s instructions, the tank(s) shall meet the following design conditions: a. The tank shall withstand external loads due to soil and water table with a 3:1 safety factor against failure and without deflection beyond manufacturer’s recommended limits. Such loading shall be considered with tank empty of all liquid and external water levels at sur face of backfill. b. Tank(s) shall withstand surface H-20 axle loading of any position over the tank without failure or deflection beyond manufacturer’s recommended limits. c. Tank(s) shall resist continuous uplifting forces due to ground water pressure without rising or deflection beyond manufacturer’s recommended limits. Such loading shall be considered with tank empty of all liquid and external water level at surface of backfill. C. Testing 1. Each tank, or tank compartment, shall be tested by manufacturer with 35kPA (5psi) internal pressure. During pressure test, the exterior of the tank shall be tested to be free of leaks with soapy water solution. 2. Each completed tank shall be subjected to a vacuum test of 10 ins Hg min. to verify structural integrity. 3. Each tank shall be designed such that it is capable of being subjected to a Precision Leak Test after installation. D. Pressure Rating 1. Tank(s) shall not be subject to pressure or vacuum except while being tested in accordance to the manufacturer’s Installation Instructions, or other methods approved by the manufacturer. Tank(s) shall be vented at all times. E. Product Storage 1. Tank(s) shall be capable of storing liquids with specific gravity up to 1.1. 2. Contact ZCL’s Engineering Department or Customer Service Representative for information on allowable product storage. 2.02 Anchoring System A. Design 1. Anchors shall be of “deadman” type designed for placement on each side of the tank. 2. Anchors shall be designed with attachment points corresponding to designated anchorage positions of tank(s). 3. Tank(s) shall be attached to anchors by means of non-corroding straps which extend between anchors and over the tanks at designated positions. Straps shall attach to anchors by means of hooks. Each strap shall be capable of being adjusted for snug fit by means of a turnbuckle. 4. Anchor System shall be designed to distribute loading equally between designated anchoring points on tank 5. Anchoring system shall not interfere with the backfill beneath tanks. B. Loading Conditions 1. When installed according to manufacturer’s instructions, Anchoring System shall be capable of withstanding continuously the uplift forces caused by ground water pressure. Such loading shall be considered with the tank empty of all liquid and external water levels at surface of backfill. 2. Each component of the Anchoring System shall have a factor of safety of a minimum of 1.2:1 against failure under the most severe loading condition. Such loading shall be considered with tank empty of all liquid and external water level at surface of backfill. C. Materials 1. Anchors shall be constructed from 25 MPa minimum strength concrete reinforced internally with steel reinforcing bars. Cement equivalent to type HSb shall be provided where required to ensure sulphate resistance. All internal reinforcement is to be cross-tied to prevent pullout of hold down points. All exposed reinforcing steel is to be corrosion protected with bonded epoxy coating. ZCL Composites Inc. www.zcl.com 1.800.661.8265 {2}
