Installation Of Solar Power System Construction Essay
Moshi Urban Water Supply and Sanitation Authority is currently operating three boreholes which depend on electric power from TANESCO to operate the submersible water pumps. Moreover the Authority has plans to explore more boreholes to supplement the diminishing surface water abstraction capacity.
The use of electric power from TANESCO has two major constraints to the Authority which are high tariffs and erratic power supply. Due to high tariffs, the cost of running the boreholes has become higher than the revenue received from selling of the abstracted water. Also, due to erratic power supply the population served by boreholes faces irregular water supply.
According to MUWSA’s 2011/2012 annual report data, electricity cost for running the boreholes was ………….. while the revenue realised in selling the produced water was ……….. this shows that, the running costs are higher than revenue by …..%. Because the Authority has plans to explore more boreholes, the electricity costs may trend hampers the sustainability of the Authority.
The overall objective of this project is to implement the solar energy power system as an alternative source of power that will cut down the costs of operating the boreholes. The solar power systems will be installed at every borehole and the electricity from TANESCO will remain at borehole stations as a backup power.
This project is intended to facilitate cost-effective water production and ensuring steady supply of water to the customers served through boreholes. The project will install solar energy power systems into three boreholes, and it is expected to reduce the boreholes operation costs by ……%.
This project is expected to cost………TZS and will be implemented for the period of …….years.

2.0 PROJECT CHARTER AND STAKEHOLDER MAP
2.1 Project background and rationale.
Moshi Urban Water Supply and Sanitation Authority was established by Waterworks Act CAP 272 charged with the responsibility of providing water supply and sewerage services in Moshi Municipality, Kilimanjaro region. It was first established in 1994 as autonomous commercial oriented water department, supervised by an Advisory Board as an outcome of implementation of the National Water Policy of 1991.
In July 1998 MUWSA became an autonomous Authority with full operational, managerial and financial powers in accordance with Water Act No.8 of 1997. However, currently MUWSA operates in accordance with Water Supply and Sanitation Act No. 12 of 2009. The Authority operates as category “A” and thus finances all its operational costs and part of capital investments, leaving the obligation of major capital investments to the Government.
MUWSA has an average water production of 25,500m/day, which comes from natural underground aquifers through springs and boreholes before being transported through 18.4km of water transmission mains and distributed in a network having a length of 249 km. Springs contributes …….% of water produced while boreholes contribute …….%. Springs uses gravity supply system while boreholes use electric pumps.
Since MUWSA finances all its operational costs, electricity is the cost centre that has been rising annually. The electricity bill has risen from TZS ……in 2011/2012 annual budget to TZS ……… in 2012/2013. Also production from boreholes has dropped from ……m3/day in financial year 2010/2011 to ……m3/day in 2011/2012 due to intermittent power supply.
For those reasons MUWSA intends to install solar energy power systems into existing three boreholes for the aim of reducing the boreholes operation costs by ……% and ensuring steady supply of water to the customers served through boreholes.
