Abstract
Accessible domestic water is a recognized basic human right. Reduced supply of water
causes high financial and social costs. This study used cost-based valuation approaches to
estimate the economic value of Mindu Dam water provision to Morogoro Municipality. It
focused on assessing water accessibility, estimating the degradation cost and the
replacement cost of water provision. It involved both quantitative and qualitative data that
were analysed by descriptive statistics and content analysis respectively. The study found
that 80% of respondents depend on non-public water sources (boreholes, wells, rainwater
and other sources), lacking metered connections to portable water as compared to 20%
with access to metered connections. Due to pollution, the municipality loses about 1 168
756 011 TZS per year for water treatment while the public suffer from sanitation and
hygienic problems as social costs due to inappropriate water supply. By using boreholes
alternative, the replacement cost of Mindu Dam is 64 074 304 515.07 TZS in the
investment year and 39 828 547 584 TZS per year thereafter. The water supply across the
study area was insufficient and partly unaffordable with increasing costs of water
treatment that are not accounted for decision-making. Finally, the study recommends to
the government and relevant authorities to make use of the economic analyses and
valuation data to refine decision making to manage sustainably natural ecosystems for
water provision to avoid degradation and the due socio-economic costs and loses.
