Technical Implementation
The implementation will be done with the help of GPS (surveying the wells and pipes...), solar cells (cheap and environmentally friendly energy production...), PET tubes (earthquake-proof and corrosion-free running ...), especially with materials and techniques to keep the maintenance very easy, the durability very long and the work later without any outside support. The goal of an installation is minimum of 40 cubic meters of water per day at an altitude of about 130 to 150 m, up the hill by a pump through 1,000 meters long pipeline.
The first deep-well-pump is installed in each of the existing wells. The first section of the pipeline brings water to an intermediate tank, half the hill up, for example, near a small settlement.
The second pump is installed in the intermediate tank. It pumps the water up to a bigger tank. This main tank is located slightly higher than the village itself, to ensure even distribution to other groups of settlers under the hill. This two-step installation works much cheaper than a single, more expensive pump and also makes it easier to distribute the water.
The water tanks are manufactured by the same men from Sumba, which also produce the concrete cylinders for the wells. This production team is able to produce tanks in high standards.
An installation includes three small hats for the watchman and maintenance materials in the near the fountain, at the intermediate and the main tank.
Each installation has a very high life expectancy, because the materials will not rust and will operate with nearly no maintenance. The lifetime of the installation is in all situations over 10 years continuous operation. This is the case for all wells, pipelines, tanks and solar installations and the control units.
