Sustainable Affordable Friendly to the Environment (SAFE) water tank
Ferrocement Water Tank Construction
Water tanks made of ferrocement are used widely in many parts of the world to store water for domestic, stock, irrigation and industrial purposes.The construction system of our Ferrocement Tanks is based on a mould of clay blocks or cement blocks, which is an eco-friendly and much cheaper alternative to the plastic PVC water tanks still used today. The cement cistern is constructed inside this mould and at the final stage of the construction process the masons remove the clay blocks of the mould.
Ferrocement tanks come in different sizes and shapes having different capacities.Within a span of just 6 days, a 5000 liter SAFE water tank is built using only locally available materials and tools.One SAFE water tank is able to provide enough clean water for 10 households to last no less than 3 months!
Your tank will be a lot cheaper than a plastic tank, have a lifetime of at least 20 years, and is easy to repair in case of cracks. The technology is extremely simple to implement, and semi-skilled construction workers can learn it with ease. Such tanks have been used on a wide scale in Asia and in some African countries, and there is huge scope for increased use for rainwater harvesting systems.
