Application of Spatial Technologies in the Maintenance of Water Distribution

DAWASA is a Public utility with higher value of non-revenue water about 37% which exceeds the required limits of 20% and more than 20,000 customers complains in every month (water leakage, lack of water, water meter, water bill). Non-revenue of 37% is the authority's major issue, implying that every month the authority lost about Tsh6.9 Billion monthly revenue collection due to the loss of water as non-revenue water. Dawasa lost 37% of capital invested in chemicals and electricity in monthly in water production as non-revenue water. Also non-revenue water of 37% reduces the ability of the utility to provide sustainable service to customers and increases complains to customers of leakages and lack of water. The research design employed in this investigation is descriptive. The study was conducted at the Ubungo Regiona of DAWASA area, with a sample size of 42 respondents. Purposive sampling was utilized to select four senior staff members, ensuring relevant information for the research objectives. Both primary and secondary data were collected to ensure accuracy. A questionnaire survey was administered to 42 operational staff, and four managerial staff were interviewed. Data analysis was performed using SPSS version 26 and Excel. The Relative Importance Index the extent to which factors affecting maintenance practices contribute to non-revenue water can be applied to spatial technology. The Relative Importance Index (RII) was used to determine factors affecting maintenance management practices contribute to non-revenue water. The factors that show RII significance concerning to this issue are Material quality, Water project design practice, Technology indicating its critical importance. Human activities (construction work)), Network duration), Construction technology practice, Water quality, Water meter duration and Water pressure were the main variables considered in the regression model. The developed model was validated using historical data to assess its predictability and accuracy. The findings highlight the effectiveness of the developed maintenance management system, resulting in spatial technology for water distribution in DAWASA. Qualitative pressure results in bars compared the design and operational of the water network shows the higher the pressure occurs during the operation lead to pipe burst especially at the joint.
