The connection shall be blocked up with stone, brick or concrete to insure a firm support for such connection and to resist all settlement in backfilling. The blocking shall be held in place by fine, dry earth firmly tamped around same.
Where excavation is in sand, clay or light earth, the water curb connections must be laid in a trench separate from any sewer lines.
Where excavation is in rock or shale, the water curb connection may be laid in the same trench which contains the sewer line, providing that a space of at lest two feet is provided between respective center lines of water connection and sewer materials, and an eighth-inch shelf is provided on which to lay the water curb connection, such shelf to be at least two feet higher in elevation than the sewer line.
The water curb connection will be placed in the exact location as called for on the plans and will run between the water main and a point three feet beyond the curb line.
At the point three feet beyond the curb line, a shut off valve shall be connected, mounted on a blocking of stone, brick or concrete to resist settlement.
A curb box shall be mounted over the gate valve in such fashion as to be centered over the operating nut and be plumb with the top of the box at the finished grade of the tree lawn.
