In the non-hydranted areas of rural America, the presence of reliable static water supplies plays an important role in the delivery of fire protection services. If naturally occurring water supplies are not present, then the creation of fire protection water supply sources becomes very important. The use of underground storage tanks is a common means by which to develop fire protection water supplies in areas without other water supply sources.
In Carroll County, Maryland, local government is involved in the planning, funding, installation, maintenance, and repair of regional 30,000-gallon underground fire protection water storage tanks. One such tank was recently installed in the Gamber area of Carroll County and we had the opportunity to video chronicle its installation.
The County was granted use of the parcel of land where the tank was installed through a deed of easement by the property owner. This agreement is critical to the success of the regional tank program because it takes all the burden of tank maintenance and repair off of the landowner and gives the local government full responsibility for the operational readiness of the tank.
The Gamber installation was awarded through a competitive bid process to Stambaugh's Inc - a local construction firm that completed the work in short order while having to work around numerous days of torrential rain. Public records show the project bid was awarded at a cost of $119,500.
Once installed, a 30,000-gallon tank generally meets the ISO requirements for a "credited source" since it can supply 250 gpm for 2 hours, is outfitted with a dry fire hydrant connection, has a lift less than 15 feet, and is accessible year round. In addition, the Carroll County tank must flow a minimum of 1,000 gpm and pumper access must be 8-ft or less from the tank's suction connection.
