In 2015 a visit was made to Madagascar to investigate the available building materials, review the cost and determine the working conditions. The partners in this project along with the villagers of Andondona, Madagascar had several exchanges of ideas which lead to some changes of ideas evoked in 2010.
The Multi-Level Energy Plan was retained and will implemented as follows:
- Use of solar panels to generate electric power.
- Electric water pumps will be used to raise water from a river level well through a series of two 2 000 liter (528.3 Gallons) holding tanks to a 10 000 liter ( 2,542 Gallons) tank the top of hill.
- Before the water is placed in the 10 000 litertank it will be run through a purification filter.
- The water will be distributed via gravity to the residences of the village.
The basic components of the system include:
- Six solar panels as well as storage batteries, controller and inverter which will be installed in the center of the village for safety.
- An electric submersible pump at the river level well which will be installed at the river level well. This pump will be used to transfer water to the first of two holding tanks 200 meters (656 feet) up hill.
- Two 2 000 liter holding tanks and associated pumps. The holding tanks will be 200 meters apart. The second tank being up hill from the first.
- One large capacity water filter 200 meters up hill from the second storage tank. Water from the filter will be gravity feed to the 10 000 liter final holding tank.
- Water from the 10 000 liter tank will be distributed to the village homes and a school
Due to power limitation this staged pumping design will be implemented. Once the first holding tank is filled it will be pumped to the second holding tank. Once the second holding tank is filled the water will be pumped to the filter then gravity feed to the final holding tank. This process will be repeated until the 10 000 liter tank is full.
The total length of the piping used to fill the tanks and distribute the water is 2 300 meters (1.43 miles).
