Ontario Municipal Code Art. 6 Monitoring and Inspection

(a) The City Inspector shall inspect all facilities installed by the contractor to insure compliance with the improvement plans, design specifications and requirements as described in § 6-8.813.

(b) Upon completion of the installation and backfill of newly installed systems, and prior to filling the pipeline with water for the pressure test, the contractor shall notify the City that the pipeline system is ready for video inspection. Said notification shall be made at least three (3) working days in advance of the actual video inspection date. The video inspection will be made by a video inspection company approved by the City shall be made in the presence of the City’s Inspector.

(1) The video inspection company shall provide the City with the color DVD or electronic video file and a written report detailing the condition of the interior of the mainline and joints. Subsequent to review of the video file and report by the City, the City will notify the contractor within three (3) business days that they may then proceed with the filling, testing, and disinfection of the pipeline; or the City will provide a list of corrective measures that must occur prior to acceptance.

(2) Should remedial activities be necessary, the reconstruction methodology shall be approved by the City prior to commencement of the work. Upon completion of the remedial construction, the contractor shall once again notify the City that the newly installed systems are ready for a video inspection. The City reserves the right to re-video any portions of the water system they determine may have been affected by the reconstruction work activities.

(a) A minimum four (4)-hour hydrostatic pressure test shall be performed and successfully completed in accordance with AWWA C600 or C605.

(b) The contractor shall apply test pressures at an approved outlet or fitting located within five (5) feet vertically of the lowest point of each pipe section to be tested and securely plug such fittings. Where air valves or other suitable outlets are unavailable, the contractor shall provide approved taps and fittings for air release, and securely plug these.

(c) Flushing of mains with water at a velocity of at least two and one-half (2.5) feet per second over its entire length shall be performed using an eccentric reducer. Velocity through outlets and fittings shall not exceed twenty five (25) feet per second during flushing.

(d) Leakage shall be computed as the total quantity of water pumped into the pipeline during the test period, including water added to reach the specified test pressure for the final time. Leakage shall not exceed the rate specified for the type of pipe tested. The contractor shall repeat the testing until the leakage does not exceed the specified leakage rate. The contractor shall repair all visible leaks regardless of the amount of leakage at their sole expense. All tests shall be completed in the presence of the City Inspector who shall record the results.

(a) Prior to bacteriological tests, an application for shutdown must be submitted pursuant to § 6-8.828.

(b) Bacteriological tests shall be analyzed by a certified ELAP laboratory with approved fields of testing for said matrix.

(c) Passing bacteriological tests on two (2) consecutive days shall be achieved prior to connecting the pipeline to the existing water system or placing the pipeline into service. Satisfactory bacteriological results shall conform to the following:

(1) No total or fecal coliform.

(2) A heterotrophic plate count less than 200 colony-forming units (CFU) per milliliter (ml).

(3) Presence of chlorine residual at or below a concentration that does not interfere with the bacteriological testing and compromise the results.

(d) If the initial chlorination fails to produce two (2) consecutive days of passing bacteriological tests, chlorination shall be repeated until two (2) consecutive days of passing bacteriological tests are achieved.

(1) If the third attempt fails to obtain two (2) consecutive days of passing bacteriological test, then the City reserves the right, and at the sole expense of the contractor, to have the contractor clean the newly installed pipeline using a high-velocity flow that produces a neutral output discharge or other technology that removes excessive dirt or debris that has entered in the new installation that conforms to water conversation and NPDES requirements.

(e) Laboratory reports shall be furnished upon issuance to the City and shall include, but not be limited to chain of custody, lab work sheet or summary letter imprinted with the laboratory’s name, address, and phone number. The report shall specify the field tests, laboratory analysis and results, and shall be signed by the laboratory director. The Engineer may require that laboratory reports be accompanied with any other form or document to ensure compliance with this section.

(a) Shutdown of the City’s in service potable lines shall be requested through an application. Said application shall be submitted to the City ten (10) working days before the first bacteriological test begins.

(b) Shutdowns are generally performed during Monday through Thursday between 9:00 a.m. and 4:00 p.m., unless granted in writing by the Engineer.

(c) The Inspector shall sign off the application when all bacteriological testing has passed, and results are accepted by the City.

(d) After all bacteriological tests have passed, the contractor or developer shall have ten working days to perform the shutdown. If there is failure to perform the shutdown within the ten working day window, bacteriological testing shall be performed once to insure pipeline sterility has been maintained.

(e) Water will be turned on when pipeline has passed all bacteriological testing. There are no exceptions.

(f) For non-steel pipelines, sixteen (16)- inches or less, the maximum time allowed is six (6) hours unless granted in writing by the Engineer.

Title to all water facilities, whether installed by the City or a developer, shall be vested in the City upon completion of all work, testing, chlorination, inspection and acceptance for use.
