The examination of plans is based upon the supposition that the data on which the design is based are correct, and that necessary legal authority has been obtained to construct the project. The responsibility for the design of structural features and the efficiency of equipment must be taken by the project designer. Approval is contingent upon satisfactory disposition of any requirements included with this report. Water supply plans are examined with regard to the location, construction and operational features of the design and maintenance of all parts of the system which may affect the safety and sanitary quality of the water. Examination is based on the standards of this department. This project consists of the installation of the following watermains: 1. 1,375 lineal feet of 8-inch PVC watermain. REQUIREMENT(S): 1. The disinfection of the watermain shall be performed according to AWWA Standard C 651. If the tablet or continuous feed methods are used, the completed watermain shall be disinfected for 24 hours with at least 50 ppm available chlorine, with a residual of at least 10 ppm throughout the length of the main at the end of the 24 hour period. 2. The watermain should be pressure tested at 150 psi for at least two hours with not more that a 2 psi pressure drop during the last hour of the test. 3. All tees, bends, and hydrants should be provided with reaction blocking, tie rods or joints designed to prevent movement. 4. Hydrants placed where the groundwater table is less than 8 feet below the ground surface shall have the drain hole plugged and be equipped with a tag stating the need for pumping after use. COMPLIANCE: No construction shall take place except in accordance with the approved plans. If it is desired to make deviations from the approved plans, the State Department of Health should be consulted and approval of the changes obtained before construction is started; otherwise, such construction is installed without proper approval, and in addition may create dangers to public health.
