RESUMEN:

The objective of this assignment is to audit the energy efficiency in the operations of DAWASA and DAWASCO, leading to suggestions for improvement in utilization of energy and reducing costs.

The Ministry of Water (MoW) has initiated a reform process to reorganize the Dar es Salaam Water and Sewerage Authority (DAWASA) and the Dar es Salaam Water and Sewerage Corporation (DAWASCo) who are responsible for delivery of water and sewerage services in the city. Under the proposed reorganization, DAWASA will be responsible for bulk water production and wastewater treatment, while DAWASCO will be the downstream distributor of water supply and will be responsible for sewerage service provision for the city. In their new mandate, they will both be major consumers of energy.

The poor operational efficiency of these utilities in Dar Es Salaam is one of the major reasons for the more than 50% of Non-Revenue Water that it faces. Poor management practices and mis-utilization of resources are also potential factors contributing to the inefficiency. The lack of a culture of promoting energy efficiency is one of the other reasons contributing to the above. Anecdotal information indicates that on average the energy spending of the two utilities is estimated to be 16% of their overall operation expenditure.

Conservation of energy by these utilities can go a long way in addressing the operational inefficiency of the utilities, and contribute to the reduction of the NRW that the city is facing. The process will begin by developing an understanding of the present status of energy consumption across the operations of the two utilities, and based on this, identify ways of improving energy efficiency.

An audit of the two Dar es Salaam water utilities, DAWASA and DAWASCO, is proposed to identify the current levels of their energy usage, and identify the scope of improvements in efficiency of energy usage.
