The vertical clear distance between sewers and drains shall be no less than 18 inches unless
otherwise approved by the Engineer or specifically indicated on the drawings. In locations
where sewers will pass over or under existing drains, the Contractor shall plan the laying of the
pipeline such that the drain pipe 1s approximately centered between joints on the sewer pipe.
Drains which are shown on the plans or located in the field and are damaged by the
Contractor shall be replaced with identical materials at the Contractor's expense unless the
Engineer agrees in writing that the Contractor was not at fault.
PIPING REPLACEMENT:
Replacement sections of pipe shall be installed at the lines and grades of the existing drain
pipes.
The replacement pipe shall be of the same size as the existing section to be replaced, and
shall maintain the existing invert slope.
Pipe joints shall be made using 2000 psi mortar, placed to produce a watertight seal.
Joints shall not be backfilled until approved for water-tightness by the Engineer.
