Lack of water and sanitation has greatly hampered the development record of various parts of the country. The socio-economic progress of many regions across the country has been slowed down due to a lack of water resources.The challenge has been to bridge the gap in existence in terms of water and sanitation for most households in the country. The water harvesting project will utilize gravity to direct the flow of water to storage tanks. These tanks storage units will be located on community land where residents can have easier access to it. Furthermore, schools also provide the conducive environment to be used for the rainwater harvesting systems.

Despite such efforts to increase access to water, the reality in most developing countries shows that there remain various obstacles. Principally, water pathogens continue to cause household challenges such that water-related diseases are contributing to morbidity rates and economic burdens in Kenya and other similar countries in the developing world. Worldwide, a primary cause of increased morbidity and premature mortality remains waterborne-related infectious (bacterial, viral and parasitic) and non-infectious (food intolerance- or intestinal disease-caused) diarrhoea, leading to about 2 million each year.

During periods of water shortage, most people in East Africa turn to rain-fed pots or cisterns as the alternative water supply. Rural domestic rainwater management was therefore affected by the inadequacy of information, which is also exacerbated by poor roads and insufficient resources (such as lack of rural electrification and limited access to information sources, e.g., the Internet). The implementation of the rain water harvesting project will improve access to and quality of water, this could help sustain the progress achieved towards the Millennium Development Goals and beyond.
