We are happy to announce a substantial extension of our rainwater harvesting activities in Walalane, Senegal.
Walalane, located in the Sahel, is a special village to us because 4 years ago we installed the first new RainCAP foil sheet tanks systems in that place. By then two tanks were installed, with the support of the Dutch ‘Hofstad Lyceum’, able to collect up to 65.000 liter of rainwater per year.
With the villagers it was upfront agreed that they would pay a user fee of 5 CFA per liter (0,008 euro/liter) to make good for operational expenses and to pay the salary of the water manager. Starting June 2012 people have been paying as agreed for the production of water and as a result the system could be secured and properly maintained:
Soon it appeared however that people from other villagers were also coming to Walalane to buy the water because of its outstanding quality resulting in a better health and lesser diseases.
The rumor spread rapidly and demand for the produced water in the Walalane water increased likewise such that the village had to put the water sales for outsiders on rations so that its own people remained in the position to buy enough water for themselves.
Part of the money that was earned with water sales was put aside by the villagers to extent the RainCAP tank capacity. With the support help of the Austrian Development Organization and the locally active NGO Caritas Kaolack it recently became possible to extend the project substantially:
Soon from now an additionally 100.000 liters of rainwater will with collected and purified for human consumption. We will aslo will improve a dilapidated concrete tank using a variety of foil sheet materials. Once the tank is repaired it can store up to 1.500.000 liters of rainwater collected from the ground surface. Interestingly we will install a floating roof in this gigantic tank to prevent the water from evaporating rapidly. The collected water will be used to boost the agricultural farming activities in and around Walalane.
