13.05.070 System evaluation.
If an on-site system takeover is approved, a thorough system examination shall be performed by an engineer employed by either the applicant or WSSC. Resulting as-built plans and certifications submitted to the WSSC by the owner’s engineer for evaluation shall include certain specific sewer and/or water information, as follows:
(a) Sewer.
(1) Manhole inspection reports shall include:
(i) Identification (with photos) of all manhole defects (damaged walls, missing steps, leakage, corbel/frame interface, bench).
(ii) Identification of manhole material including the type of frame and cover and connections (parged, gaskets).
(2) Sewer CCTV videotapes completed in the following manner:
(i) Sewer segment videotaped in its entirety (obstructions, if encountered, shall be removed and the segment re-taped).
(ii) Recording shall be VHS format.
(iii) Segment shall be plugged and picture quality free of steam or distortions.
(3) Sewer CCTV inspection reports shall include:
(i) Identification of segment televised.
(ii) Location, diameter and address of each connection.
(iii) Identification and location of all pipe defects (open or leaking joints, cracked or broken pipes, sags or bellies in the segment, root penetrations).
(b) Water.
(1) Prepare an inspection summary of the water system inventory to include:
(i) Leaking service connections, valves or mains.
(ii) All valve curb boxes or meter boxes requiring grade adjustment and those which are not accessible or operable (key must fit nut).
(iii) Missing and nonstandard curb cocks, curb boxes and covers.
(iv) Identify the potential need for water line looping to ensure circulation or the installation of additional valves to isolate smaller segments during future service disruption.
(v) Each individual dwelling unit (e.g., single-family house, townhouse, and/or each commercial building/unit) which will require an inside water meter and an outside cut-off valve, and the proposed location of each meter and valve; the locations where curb boxes/valves and inside meter yokes (horns) must be installed; and the location of the master meter to be abandoned.
(vi) The location of valve stem extensions which must be installed so that the operating nut is between two and four feet below finished grade.
(vii) The location of fire hydrant lead valves.
(2) Perform flow tests of all fire hydrants in the system and report results. (Amended during 2019 codification; PD 98-01 § VII)
