Fire Department water reservoir installation requirements
Subject: Fire Department water reservoir installation requirements for the Village of Merton Community Fire Department District, including both the Town and Village of Merton.
Following is a summary of the Fire Department requirements for the installation of new or upgraded underground water storage tanks. These requirements are in addition to any engineering specifications, which define installation. This document is to more accurately define the requirements of the Merton Community Fire Department as they apply to the use of underground water sources.
Sub dividers must provide emergency water reservoirs as follows.
5-40 lots: 1-10,000 gallon tank
41-80 lots: 2-10,000 gallon tanks
81-120 lots: 3-10,000 gallon tanks
( above 120 lots, one additional tank for every 40 lots)
1. The minimum capacity of each tank shall be 10,000 gallons or larger by order of the Fire Chief
2. Sand bedding and back fill will be used on all tank installations.
3. All tanks will be hydrostatically tested and coated to NFPA standards.
4. The finished height of the Drafting Pipe shall be 24 inches above the finished roadway surface, measuring from the centerline of the 4-1/2 inch hydrant fitting. ( This is not the distance above grade at the pipe)
5. The Drafting Pipe shall extend to within 6 inches of the bottom of the tank. The total length of the drafting pipe shall be kept to a minimum after meeting item #4. The Drafting pipe must be 6 inches in diameter and terminate with an elbow to accept a 4-1/2 male hydrant fitting with a cap and chain.
6. A screened 4 inch diameter vent pipe, with the opening facing downward, will be included on all tanks.
