<P> Fire pumps are needed when the local municipal water system can not provide sufficient pressure to meet the hydraulic design requirements of the fire sprinkler system . This usually occurs if the building is very tall , such as in high - rise buildings , or in systems that require a relatively high terminal pressure at the fire sprinkler in order to provide a large volume of water , such as in storage warehouses . Fire pumps are also needed if fire protection water supply is provided from a ground level water storage tank . </P>
