Fire Sprinkler - Concrete Water Storage Tank

Fire Sprinkler - Concrete Water Storage Tank

Fire Sprinkler - Concrete Water Storage Tank

(OP)
Hi guys

Any guides on minimum dimensions for a low level access hatch for a concrete tank?  I have no top entry access or high side entry level.

I also need to seal the water tank as we will now be scrapping the need for a butyl liner.

cheers

RE: Fire Sprinkler - Concrete Water Storage Tank

Pressure tanks are often built with 14"x18" elliptical manways.  Storage tanks of any size normally use 24" round or larger manways.  It depends on how much it will be used and all.

If any kind of scaffolding will be used in the tank, check if there is a minimum dimension associated with the scaffolding.
