Collierville Fire Department Tests Hydrant Water Pressure

The Collierville Fire Department is conducting routine maintenance on 3,445 hydrants in the Town of Collierville. During this process, firefighters will completely flush out area hydrants, freeing them of debris, and collect data regarding water pressure. The annual flow test contributes to the Insurance Service Organization (ISO) Rating, where Collierville recently moved from a Class 3 to Class 2. Water supply accounts for 40% of the ISO Rating – the highest contributing factor; the Fire Department makes up 50% and communications 10% of the total rating. The Fire Suppression Rating Schedule (the ISO rating review qualifications and numeric scale) compares the water supply available at representative areas of the community with the amount needed to fight a fire in the types of buildings there are at that location. In addition, there are some specific minimum requirements for specific classes; Collierville is required to flow 3,500 gallons of water per minute for 3 hours. The Collierville Fire Department has just started the hydrant maintenance process and will be finished by the end of November.
