The water stored saves people from the daily task of walking long distances to fetch water from sources which are often contaminated. The water in a taanka is usually only used for drinking. If any year there was less than normal rainfall and household tanka do not get filled, water would instead be obtained from nearby wells and tanks to fill ...
It is easy to add water-efficient applications but it is the proper maintenance and inspection of it which will lead to long-term changes. A water conservation plan can be created, including adding various goals and benchmarks for both the employees and the company. [31]

The well-water is known to attract insects, animals, and many other germ breeding organisms. These stepwells, being a common space in frequent use by the inhabitants of the area, were considered to be a source of spreading epidemics and diseases.
A check dam is a small, sometimes temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity. [1] Check dams themselves are not a type of new technology; rather, they are an ancient technique dating from the second century AD. [ 2 ]
configuration of domestic rainwater harvesting system in Uganda. [1]Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off.. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground w
When the water in the well is below the water table level, the pressure at the bottom of the well due to the water in the well will be less than P g and water will be forced into the well. Referring to the diagram, if z is the distance from the bottom of the well to the well water level and z T is the distance from the bottom of the well to the ...
Fresh water can have widely ranging pH values depending on the geology of the drainage basin or aquifer and the influence of contaminant inputs . If the water is acidic (lower than 7), lime, soda ash, or sodium hydroxide can be added to raise the pH during water purification processes. Lime addition increases the calcium ion concentration, thus ...
