# Water storage container made of cement mortar reinforced by layers of steel mesh (WHO et al. 2003).
# A water tank constructed on a reinforced cement base with sides of wire meshes and cement mortar (Sharma P et al. 1980)

==Explanation==
Ferrocement water tanks are made of steel mesh and wire, covered on the inside and
outside with a thin layer of cement-and-sand mortar. The tanks can be used for individual
households or for whole communities, and they provide a relatively inexpensive and
easy-to-maintain storage method. To avoid bending forces in the material, most
ferrocement tanks have curved walls, in the form of a cylinder, a globe or an egg WHO et
al. 2003).

A ferrocement tank consists of a reinforced cement base with a wire mesh to form the sides
and shape of the tank. The wire mesh when in position is then covered with cement mortar
plaster to complete the water storage tank. The tanks are usually made on site but small
tanks can be made off-site and transported to its point of use (Plumbing Working Group
2008).

Ferrocement tank is a viable alternative for a remote site where access is difficult. The tank
is a simple form of construction. It is durable provided the materials are of good quality and
the mortar is correctly mixed. The larger tanks require welded mesh of approximately 4mm
in diameter. The small tanks may only require chicken wire mesh for reinforcement. These
tanks are often used for drinking water storage. To protect the water from any
contamination and insects the tanks should be fitted with protective covers (Plumbing
Working Group 2008).

==Example==
“Rooftop catchment systems gather rainwater from the roofs of houses, schools, etc., using
gutters and downpipes (made of local wood, bamboo, galvanized iron or PVC), and lead it to
storage containers that range from simple pots to large ferrocement tanks.” WHO et al.
2003)
