For the construction of the school, it is essential to create a basic hygienic supply and to provide clean water. The necessary expertise and financial resources for technical solutions are lacking on site. Therefore, the Iyolwa project group has been working on the planning and dimensioning of sanitary facilities and water filtration plants since March 2015. The execution of the project is divided into the following project phases:
For the sanitary complex, we decided to build so-called urine-diverting dry toilets. Explained in more detail are the operating principle and reasons for choosing this technology and the maintenance and operating concept. Training of school staff and pupils takes place at regular intervals.
For the construction of the aboveground cistern with water treatment plant for the girls’ shelter, a slow sand filter system was used. Personnel have also been trained for this purpose. In addition, the use of sand filters in private households was trained in workshops.
The technical building was built using environmentally friendly ISSB technology. For this purpose, bricklayers were trained, and workshops were held for students of the Technical School Iyolwa.
Two underground cisterns with a total capacity of 80,000 litres were built to supply the school with water. This includes a water treatment plant and an elevated tank. Slow sand filters and ISSB technology were also installed again.
