Revision history [back]

The use of plastic plastic tanks for rainwater harvesting is becoming increasingly common as rotational moulding factories become more common, resulting in the cost of feedstocks decreasing. In East Africa you have kentainers in Nairobi, Rototanks in Uganda, and the name of the factory in Addis Ababa escapes me.

Plastic tanks have the advantage of being cheap and relatively easy to transport and install.

The plastic is generally not UV stabilised, so can be serviceable for 2 to 5 years unless a shade is provided. I would think that the costs of plastic would be similar to those of ferro cement. I have used both. Ferro cement has a tendency to creep, and once cracked is difficult to repair.
