Johannesburg, 1996 / Current practice of'the rural water sector in Mozambique does not generally consider all factors
that have influenc.eon project sustainability, The urgent need to provide returnees in rural areas
with safe water, does not give adequate time to engineers, technicians and those involved in the
sector, to conceive and plan a water project property.
A Decision Support System (DSS) for rural water supply has been proposed to assist the decision
making process to be more systematic, fast and comprehensive. It requires a number of input cata
variables which are not difficult to obtain and these variables have been selected to ensure that
most aspects inherent in a successful project are considered. The main achievement of this system
is the project report, similar to a project preliminary design, and the financial results which are
important for project assessment and ranking.
The Decision Support System is a computational model which uses engineering and economics
approach to combine and process input data and information contained in its database. While the
calculation method does not need constant updating, the database has to be verified frequently
to produce reliable results. South African prices have been used in the database construction but
a correction factor facility was incorporated to adjust and make the model useable in
Mozambique.
The model has been designed to be used by planners, engineers and technicians, and funding
agencies. The model can be used by planners to assess implication of policy decisions on future
water supplies and water resources development. For engineers and technicians, the model
estimates water demands, project components sizes and quantities, and water source development
and reliability. To funding agencies, the model is a tool to determine the best investment scenario
of a rural water supply project.
