Dry Hydrants- What are they, who needs them and when are they required?
Water supply systems for fire fighting in rural areas are commonly available from cisterns, ponds, and/or underground tanks. The outlet on the system is 6” (or 4 ½ “) NST male elbow at 24” above finish grade of the driveway or is a standard dry hydrant. The outlet is located at least 100 feet from the structures. These systems are non-pressurized. A fire truck must draft water from the hydrant. As per NFPA 1142, the standard flow requirement is 1000 gallons per minute. The test procedure is normally preformed upon completion of the system before a Certificate of Occupancy is issued for new construction or at the request of a property owner. For additional requirements and specification on tanks, locations, etc. please see the dry hydrant packet below.
The site must first be inspected in-person for verification of completion. The site must be inspected for proper fittings and completed connections to the tanks, cistern or pond. During the inspection completion of access to draft site must be compete and clear of any and all obstructions. Under no circumstances shall fire apparatus be taken to the site before an in-person inspection is complete.
Water storage for fire protection supply is required for areas not on municipal water supply. Water supply is based on building size per NFPA 1142. As stated in NFPA 1142 “The AHJ shall be permitted to reduce the water supply required by this standard for manual fire-fighting purposes when a structure is protected by an approved automatic sprinkler system”. The Basalt & Rural Fire Protection District as the AHJ may allow water storage to be reduced by 75% if the building is provided with an automatic fire sprinkler system. The tank shall be filled and maintained by the owner.
