Measurements will be made by means of9O degrees V-Notch weirs or inflatable test balls placed in the lines. Measurements shall be taken at all points where, in the opinion of the ENGINEER, the flow of water in the sewers is greater than the maximum allowable leakage. The maximum allowable rate of leakage shall be 100 gallons per inch diameter of pipe per mile for 24 hours. . In case measurements indicate a leakage greater than the maximum' allowable leakage at the outlet of new construction, additional measurements shall be taken and continued until all leaks are located and the necessary repairs and corrective work have reduced the leakage in the section being tested below the maximum allowed by the specifications. 404.2 DEFLECTION TEST Upon completion of sewer construction and backfill, the CONTRACTOR will pull a .mandrel through all lines 12" and smaller.
