Background Information

St. Mary’s Mumias girls High school is located in Mumias Central Division, Nabongo Location, Ekero ward, Mumias sub- county, Mumias Constituency. The school has a total of thirty eight (38) teachers of which twenty (20) are female, 18 are male, Eleven (11) are BOG and 15 support staff. The school has total number of 860 students including one girl with disability. The population of the school is comprised of students from form one (210), form 2 (208), form 3 (265), form 4 (177). The school is now ranked as one of the best National schools in Kakamega County. This is as a result of devolution that is gradually taking place in Kenya, thus putting pressure on the schools infrastructure/facilities (need for more WASH facilities in the School). The school has a total of 17 classrooms, 24 toilets (day time) for the students and seven (7) toilets for the teachers. The school has nine dormitories and inside there are a number washrooms and bathrooms.

(Editor's Note: While this many people may have access on any given day, realistically a single water source can only support a population of 350-500 people.  This community would be a good candidate for a second project in the future so adequate water is available. To learn more, click here.)

The school has ten hand washing facilities for students and one for the teachers and support staff.


The school’s main source of water is a bore hole and 3 plastic tanks with the capacity of 9000 litres. These tanks are not sufficient to serve the high population of the school and also during the dry seasons, there is not enough water to meet the needs of the whole population, teachers and support staff included. As a result, the students are forced to use as little water as possible which may not meet their needs such as drinking, bathing, cleaning and washing. This has lead to a high demand for the construction of a bigger rain water harvesting tank to accommodate the needs of all the school’s population and hence be able to arrest the situation.

The sanitation is a challenge since 32 toilets are not enough considering the population of more than 860 students therefore it is not sufficient to accommodate all the students, resulting in long lines. This has made the school to request the organization (WEWASAFO) to consider them to construct additional toilets so as to meet all the needs of the student.

The students admitted that they always wash their hands after toilet use though they have to queue for long time so as to wash their hands. This results into a lot of time wasted by the students. In most cases, they are late for classes and sometimes being punished for being late in the lessons.

Project Type

For a rainwater collection system, we build gutters around a building with good, clean roofing to channel rain where we want it. From there, the water falls through a filtered inlet pipe into a high-capacity storage tank, the size of which is based on population and average rainfall patterns. In the tank, water can be stored for months, where it is easily treated and accessed. Learn more here!
