City To Color Code Fire Hydrants According to Flow Capacity

The City of Smithville will soon have to undertake a project to color code fire hydrants according to their pressure flow capacity in accordance with regulations of the Tennessee Department of Environment and Conservation.

Currently, all the city’s fire hydrant tops have the same color “red”.

The city will have to color code the bonnet/cap of the hydrants as follows:

Class C-RED- Less than 500 gallons per minute

Class D- Black bonnet or covering-Temporarily out of service.

During Monday night’s meeting of the Smithville Mayor and Aldermen, Fire Chief Charlie Parker explained that fire department pumper trucks are prohibited from connecting to hydrants that are a Class C. These hydrants may be used to fill the booster tanks on any fire apparatus by using the water system’s available pressure only (fire pumps shall not be engaged during refill operations from a Class C hydrant).

“Technically the hydrants are supposed to be color coded as far as to what pressure they flow and in accordance with that ruling fire departments are not supposed to connect to a hydrant with a red top. As you know in Smithville all of our hydrants have a red top because they are not color coded. I would like to see if we could get some extra help with seasonal workers along with our fire department personnel. Since its fire hydrants, everybody thinks it’s a fire department project but we don’t have the resources or manpower to get them tested. I have been working with the 911 system over the last couple of years and now we have most of our hydrants digitized on a GIS map so they are located and numbered but we have to flow them and paint them to whatever color they need to be and get the information entered into the computer system so we will have it. Then we are supposed to annually flow them and do a spot check. It is not the time of the year to do this now. I’m just coming to you (mayor and aldermen) to see if we can come up with a plan to get the hydrants tested because it will benefit all of us, not just the fire department but also the water department too. We have roughly about 240 hydrants already mapped out but I’m thinking it will probably be closer to 270 because there some hydrants not mapped especially near the industrial parks and Walmart that we would like to add to the GIS map too because that benefits us (firefighters) being about to look on a map and know if we have a really good hydrant especially with the ladder truck where we need higher flows of water,” said Chief Parker.

Mayor Jimmy Poss said the city might be able to hire some part time help to assist with the project.

Utilities are now required under state law to account for water used. “In order for our utility to comply, we must require that you (Smithville Fire Department) report on a monthly basis; when, where, and an estimate of how much water was used,” wrote Public Works Director Kevin Robinson, in a letter to Chief Parker.
