Designing Underground Water Tank

[abisabo]

I need advise on which steps to carry when I am designing a concrete underground tank. Its my first time to do it. It has to collect water from a weighbridge building roof and attached office building.We came up with this because we want the to reserve the rainwater for future use like watering plants etc.

Thank You.

Why not a pre-manufactured tank? Is it too large?

I had a project that needed a cistern for fire water and we used a manufactured polyethylene tank. The supplier could provide a tank for the 200,000 gal requirement.

My only advise on the subject is to watch the plumbers and installers like a hawk. On some tanks we were installing they forgot to put the connector pipe between the tanks before pouring concrete and they had some not-fun clean up to do. Then a plug was left out causing 3000+ gallons of water to leak out of the tanks and under the building...
