Handeni Trunk Main Water Supply and Sanitation Authority (HTM-WSSA) operates one of 8 National Projects (NP) in Tanzania. Up to the year 2004, NPs were governed and supervised directly by the Ministry of Water. Thereafter, NPs have been declared commercial water utilities under the MoW Directorate of Urban Water Supply with the long-term objective to cover costs for Operation & Maintenance. HTM-WSSA supplies via a pumped and gravity supply scheme currently (2014) 260,000 beneficiaries in North-Eastern Tanzania, which live in the rural districts of Handeni and Korogwe in Tanga Region. The scheme comprises two intakes at the Pangani River, one treatment plant, 6 pump stations, 316 km of trunk mains and 150 km of primary distribution network. The effective service area covers 2,400 km2 which itself spans over 5,000 km2. Within the service area of HTM fall 76 service centers of different size ranging from villages over rural and urban centers to the Handeni district capital.
The beneficiaries’ water demand has exceeded the schemes design capacity of 180,000 people. Further hardship to the continuity of water services pose the absence of preventive maintenance, upgrade and expansion of the supply scheme after its completion in 1985 (commissioned by KfW) as well as unreliable power supply. Today out of the 260,000 beneficiaries living in the service area, 42% receive water service between 12 and 24 hours per day, 29% receive less, and the remaining 29% receive no water at all.
Since December 2011 a GIZ development advisor has been deployed in HTM Water and Sanitation Authority to assist with the organizational development of efficient and effective use of limited resources. For the necessary overhaul of the scheme to be able to serve in bulk 500,000 beneficiaries by the year 2030, Business Cases have been elaborated for the rehabilitation and extension of HTM water supply network. Partnerships with the private sector have been considered to achieve sustainable bulk water supply to its service area. Through performance-based management contracts, ventures in energy efficiency, renewable energies and social entrepreneurship, synergies with formal and informal private sector stakeholders shall be created to assure water security and universal access to safe water in its service area.
