the fourth consists in protecting the structure, the location and the catchment area (covering the capture box with a layer of soil and grass, enclosing the basin, setting up a protective gutter on top and around the spring of in order to intercept runoff flows and the digging of a small channel to remove unused water) as well as making arrangements, for example by providing small areas for washing nearby in order to facilitate the work of the women the third concerns creating the exterior structure of masonry for the drawing location, and of a concrete slab so that the spring does not turn into a quagmire. The seal should be carefully provided for using a layer of clay or a plastic tarp, or better yet, both. The capture box is then covered with mortar. Once the filtering has been carried out using gravel, one or several drainage pipes are attached to the end of the trench and a blockage wall at the exit is created using clay or concrete. This trench is then filled with large rocks or stones that filter it and allow the water to flow easily. A trench is dug in order to recover the water a little further away so that it does not become polluted in contact with the last layers of land that it passes through. the second has for purpose to gather the streams of water into a well or capture box. the first consists, after having conducted studies beforehand on the land, purity of the water, flow, consumption and expectations of the population, in cleaning, brush clearing, weeding, earth removal and crushing down to the impermeable layer of the ground, with the assistance of the population, the perimeter of the spring. The process generally comprises 5 steps : It can be applied if the spring emerges easily on its own with a sufficient flow. Spring catchment in Cameroon Photo Ch.Le Jallé PSEau PSEau For the two other cases, please refer to the other data sheet "Spring catchment and arrangement with Reservoir or with Drainage". Here, we will cover only the simplest case. Finally, if the emergence of the spring is diffuse (wet or swampy land, for example) or deep, drainage must be provided upstream of the spring. If a similar case is encountered but with a flow that is less than that needed for consumption, a reservoir must also be built. If its emergence is very precisely located and not deep (less than 2m) and if the planned consumption is less than the flow of the spring, the simplest method described here will be used. The choice for the method depends on the characteristics of the spring (location, flow, extent, consumption to be satisfied). There are 3 main methods for the catchment and arrangement of a spring : a simple method, and another more elaborate one if adding a reservoir is desired and a last one for drainage. These are mostly inhabitants of rural mountain villages or underprivileged areas, but also average-sized towns when springs can be found.Ĥ) What does this process involve ? How is it used ? The catchment of springs can also be more elaborate and associated with the construction of a mini-network for water distribution serving via gravity one or several villages that are far from the catchment site. Dig dug arrangement dailymotion free#Obtain quality water by drawing from a spring.īecause it is a process that is simple as well as inexpensive that has been used since ancient times and makes it possible to obtain pure water, near and easy access, and most often free of charge.
