We are working on 8 story retail/residential building 90,000SF each floor, 95 ft High from the fire department access.
Pressure at street level is available at 70 psi. One fire pump station is to supply entire sprinkler system and 7 standpipes. Problem here is the Project Architect has not seen the building would need a secondary water source to supply fire protection system.
City has required that water tank as the secondary on-site water supply, in addition to main supply from the city water.
Roof structural is not able to support the weight of water tank and the only places abailable for water tank placement for the building is on 1st floor and the basement.
Can anyone please let me know 1)how would supply line from water tank is sized 2) how would the supply line taps to main fire water supply.
Would water tank need its own Boost Pump Assembly to keep stored water pressure to city water supply pressure?
