Design and Construction Standards

The design of the domestic hot water system shall comply with the International Building Code, latest edition, and the 1986 Georgia Energy Code. The water temperature shall be regulated producing maximum 120°F at lavatory and shower head discharge. Water storage facilities and tempering valves shall be utilized at the above temperatures dependent upon capacity of facility.

Restrooms, custodial equipment and mop sink rooms, and mechanical rooms shall have floor drains with the floor sloped toward the drain. Trap primers shall be installed on all floor drains.

The use of interior sewage lift station is prohibited. If necessary the lift stations shall be located outside the building, accessible to vehicular traffic lanes, and properly landscaped to conceal the dome of the pumping unit.

Storm lift pumps shall be located in below grade mechanical or equipment rooms where an accumulation of water occurs. The discharge shall be to the storm water system.

Automatic, battery powered flush valves are preferred in public restrooms.

Preferred Mfg.: Sloan Royal, Sloan Regal or Zurn

All buildings should be designed to have automatic sprinkler systems. Exceptions will be on a case by case basis with the approval of the University. The systems will be operative when the facility is presented for final inspection.

Restroom and laboratory faucets shall be all brass construction with replaceable brass valve control units.

Preferred Mfg.: Chicago, T & S, or equal

Each facility shall have a single shut-off valve on the domestic water supply.

Restrooms shall have valves on the hot and cold water supplies to each fixture so that the unit can be shut-off without disrupting the entire building water service.

Each zone or floor of a facility shall have shut-off valves on hot and cold water supply lines for maintenance of the facility.

Preferred Mfg.: (Manufactured in U.S.A, no imports): NIBCO, Crane, Stockham or Hammond

Underground PVC piping shall have tracer wire and tape installed along with the pipe.

Water piping installed inside of buildings shall be copper. Water piping outside of buildings shall be cast iron or schedule 40 PVC.

Preferred Mfg.: No preference

Provide mop sinks in Custodial closets. Mop sinks shall be minimum 24" x 24" low "shoulder" type, with 3" curb, splash guards and proper fixture hardware.

Provide at least one (1) hose bib with vacuum breaker service every 50 - 75 feet of building perimeter. Recessed hose bib spigots are discouraged.

Concealed spigots on lawn or sidewalks are prohibited.

Preferred Mfg.: American Standard, Kohler

Backflow preventers will be installed on every water supply and fire system supply lines connected to the campus water system. The preferred location of the backflow preventer is in the ground floor mechanical room.

Adequate space will be provided around every backflow preventer to permit testing and repair by maintenance personnel. Backflow preventers in mechanical rooms will be close to the floor. A minimum of twelve inches is required. Backflow preventers will be installed in such a manner as to permit testing without shutting down water to the facility. Where possible, the use of two smaller backflow preventer assemblies rather than one large one on incoming lines is suggested.

All backflow preventers will be tested and certified prior to turn over the Georgia Southern University.

Devices should be selected based upon the "Manual of Cross- Connection Control" by the Foundation for Cross-Connection Control and Hydraulic Research, University of Southern California, and the EPA's Cross-Connection Manual.

Also, see Site Work (Backflow Preventer).

All hose bibbs, mop sinks and other fixtures that permit the attachment of hoses will be equipped with vacuum breakers.
