Abstract:

Adequate access to safe drinking water and sanitation is essential to health and represents a fundamental human right. The core task of drinking water suppliers is to provide drinking waterthat complies with governmental regulations. Especially small rural community water suppliesare often subject to restricting frame conditions and tend to lack capacities for ensuring thedesired product of safe drinking water. These preconditions create a particular need to supportoperators of small water supply facilities, in order to guarantee sufficient water quality. TheWater Safety Plan (WSP) concept developed by the WHO detects, assesses and managesrisks along the whole water supply chain, from catchment to consumer, and aims to prevent thewhole system from contamination. The application of this preventive management approachshall help operators, to ensure long-term and proper functioning of the system and to provide a safe product.This master thesis has the objective to contribute to the long-term sustainable operation of thewater supply system of Paroisse de Rwaza and the system extension to the non-governmentalorganisation Future for Kids, and therefore to a secured water supply with safe drinking water inthe area. In this study the water supply system of concern is examined, a quantitative andqualitative water examination is performed and a risk analysis according to the WSP approachis conducted. Based on that, Operation and Maintenance (O&M) check lists, timetables andwork instructions for a sustainable O&M of the network are developed.It was found, that the water quantity provided by the springs should be sufficient for the suppliedconsumers. However, the water quality does not meet health based quality standards andshould therefore not be used for human consumption without prior treatment. Finally, thefindings of this study recommend the elimination of the 70 determined risks through theapplication of the identified O&M activities.
