Leakage shall be defined as the quantity of water that must be supplied into the pipe section being tested to maintain a pressure within five pounds per square inch (5 psi) of the specified leakage test pressure after the pipe has been filled with water and the air in the pipeline has been expelled. No installation will be accepted if the leakage is greater than that determined by the formula:
L = (ND X Square Root of P) Divided by 7,400
Where: L = allowable leakage, in gallons per hour
N = number of joints in the length of pipeline tested
D = nominal diameter of pipe, in inches
P = average test pressure during the leakage test, in
pounds per square inch (gauge)
Leakage gallons per hour = (# of joints) X (Pipe Diameter) X (.00148)
All pressure and leakage tests are performed at one hundred and twenty pounds per square inch (120 psi).
Revise 5th sentence as follows:
..... Waterworks line by the use of a reduced pressure backflow assembly.
Revise 6th sentence as follows:
..... pressure of one hundred and twenty pounds per square inch (120 psi).

A Sensus SR 5/8 inch x 3/4 inch meter must be installed across the check valve and routinely read to detect any unauthorized usage on the sprinkler line. This meter will be installed, read and billed the minimum rate only, at the customer's expense. A complete set of drawings of a proposed sprinkler system installation must be submitted to the Department of Waterworks for approval. All taps, tie-ins and installations will be made at the customer's expense. See Detailed Specifications Section for sprinkler system installation requirements.
A Diagrams and Detailed Specifications Section is proposed as Section VI. Detailed Diagrams and Specifications.
- Fire Hydrant Detail
- Canal Crossing Casing Drawing
- PVC Casing Diagram
- Reduced Pressure Backflow Specifications and Diagram
- Sprinkler System Specifications and Diagrams
- Pipe Deflection Diagrams and Charts
These detailed specifications will be referenced in the written body of the regulations.
