Where access to groundwater is limited, rainwater harvesting in underground tanks can be an effective and low-cost solution. Water stored in the rainy season can be used in the dry season and lifted from the tank with a rope pump or with a FlexiEmas pump (see PVC pumps), which can elevate water up to 30 m.
The government, with support from organisations such as UNICEF and IRCSA (International Rainwater Catchment Systems Association) started a programme to construct one million rainwatertanks in Brazil.
Practica foundation is testing various options for low-cost storage and groundwater recharge like the "Reed cement tank" and the "Tube recharge"

Capacity
For example 3500 liter.
Costs
Material costs for EMAS tanks consist of sand and four 50 kg bags of cement for each tank.
