Annual general report of the controller and - Parliament of Tanzania

– IPTL and Songas accounted for about 90% of TANESCO
revenues.
6.5.2 Noted Anomalies on Water Supplies Sector
It has been noted that, large part of the Water and
Sewerage Authorities uses the old distribution networks,
this leads to significant divergence from the average
industry unaccounted water level, illegal connection,
experience inconveniences in billing and collection system
and below the industry average revenue per shilling spent
on electricity as explained below:-
• Indequate Revenue from Water and Below Average
Revenue per shilling spent on power
Unaccounted for water at DUWASA is 40%, this is above
industrial average which stands at 31.8% and, electricity
expenses at DUWASA are above industry average,
consequently revenue per 1 Shs. spent on electricity is
below industry average. Management should strive to
control electricity expense. The Authority revenue has
increased by 1% while its expenditure has increased by 14%
from last financial year.
• Metered Customer, Water Billing and Revenue
The Billing system at TAWASA is open to every staff of the
section from senior to junior staff whom cannot pass
entries for amendment of bills. Further, most of the
amendments made, lack proper supportive documents and
authorization such as customers’ written complaints
approved by the Managing Director or any other officer
delegated by the Managing Director to do so, and some
customers are not metered. This could make it difficult to
hold any one responsible incase of embezzlement of
revenue by unscrupulous employees. It is recommended
that, all adjustment of bills should be supported by written
complaints from the customers and be authorized by the
Managing Director or the Business Manager jointly with the
Finance Manager on his behalf.
