Dear Patrick
Congratulations with reducing the cost rainwater storage tanks. One of your lessons learned is using local knowledge.
There are several organisations in Tanzania with knowledge on rainwater harvesting. One is the SHIPO SMART Centre in Njombe.
They promote the so called WIRE BRICK CEMENT TANK. So making tanks with bricks or blocks and support these bricks outside with wire.
Cost of Materials / cubic metre is 20 -30 US$ depending on size.
Another technology is the so called The TUBE RECHARGE, so using the ground as storage. This is only viable with shallow water levels of 10 to 30 m deep where it is possible to make hand dug or hand drilled wells, but where possible, it is cheaper than any storage tank
A third option is the EMAS Underground tank. EMAS says that tanks of 7000 litres can be made with 6 bags of cement.
Water can be pumped out with a 40US$ EMAS pump. For more information see websites of EMAS and SHIPO
Succes with your work

I also wish to work out some solution to recharge the depleting natural water sources in the Hill districts of Uttarakhand (India). Can I have some constructive suggestions please.

Wonderfully executed project in Tanzania.
I also wish to work out some solution to recharge the depleting natural water sources in the Hill districts of Uttarakhand (India). Can I have some constructive suggestions please.
