SECTION 252:631-3-17. Water system connections

(a)   PWS systems must not allow the connection of a new customer without an approved sewage disposal system, as defined in OAC 252:641 (Individual and Small Public On-Site Sewage Disposal Systems) or OAC 252:656 (Water Pollution Control Construction).

(b)   PWS systems shall:

(1)   not allow a physical connection between a line carrying a public drinking water supply and a line carrying water of unknown or questionable quality.

(2)   not allow connections from any PWS system to any device or system that poses a health threat unless it is equipped with an air gap of at least 6 inches or two pipe diameters, whichever is larger, above the overflow or drain pipe. The installation of a reduced pressure zone backflow prevention device will be considered in lieu of an air gap. To allow maintenance on the backflow prevention device, the design shall include a diversion line with equal backflow prevention. Do not locate backflow prevention devices in a pit or vault where they can become submerged. A fire suppression system is not considered a hazardous water supply.

(3)   not allow a cross-connection between a public water system and any private water system.

(4)   provide an air gap at all points where finished water is connected to a drain.
