(a) Sewers must be built so as to remain true to line and grade. The inclining grade of the bottom of the sewer after completion shall be such that, after flooding, the flood water will drain off so that no remaining puddle of water will be deeper than one-half of an inch on pipe larger than thirty-six inches internal diameter or smaller and three-quarters of an inch on pipe larger than thirty-six inches internal diameter. Any section of pipe that does not comply with the specifications at any time previous to final acceptance of the work shall be replaced or relaid.
(b) The contractor will be held strictly responsible that all parts of the work shall bear the load of the backfill. If cracks one-hundredth of an inch develop in the pipe within one year from the date of final acceptance of the work, the contractor will be required to replace at his or her expense all such cracked pipe. To this end, the contractor is advised to purchase pipe under a guarantee from the manufacturer, guaranteeing proper service of sewer pipe under conditions established by the plans, specifications and local conditions at the site of the work.
