Implementation of WHO water safety plans for small utility units in the Republic of Moldova [8.58 mb]
Zusammenfassung (Englisch)

This thesis presents preparative studies on the path towards implementing the WHO Water Safety Plans for the city of Telene?ti in the Republic of Moldova. The WHO Water Safety Plans (WSPs) are a risk-management approach to ensure drinking water quality in a sustainable way. The main focus of the WSPs is to improve the water quality in the long run based on actions at the catchment area, rather than implementing treatment options which might be expensive for some regions of the world. The technical conditions of the water supply and sanitation systems of Moldova are heavily degraded due to lack of maintenance and investments, so that water utilities cannot reliably provide safe drinking water. This work specifically investigates the situation of the Telene?ti water supply system. A broad collection of data has been assembled to describe the fundamental parameters and characteristics of the existing utility services and to spot the major risks and the extent and effectiveness of existing control measures. Major issues include a strongly increased ammonium content in the source water and recurring microbial contamination cases. These are presumably caused by organic sewage leaching or waste washout, common use of pit latrines, and widespread livestock keeping, as well as due to the frequent pipe breaks and possibly through unauthorized access and related backflow. Structured along the modular WSP development process, this thesis analyses and comments on each module, outlines evident risks in the water utility of Telene?ti and gives recommendations to help the course of a future WSP implementation. It thus serves as a viable starting point for WSP pilot studies and could stimulate an active development in water system management in the region.
