If local conditions prevent a lateral separation of ten feet, what alternatives are available?
If it is not possible to obtain ten feet separation the Agency may approve construction in which the water main invert must be 18 inches above the crown of the sewer. In parallel situations where it is not possible to obtain the lateral or vertical separation, then the Agency may approve construction in which the sewer is constructed of water main equivalent pipe and pressure tested to the maximum expected surcharge head before backfilling.
