Annual general report of the controller and - Parliament of Tanzania

The revenue relating to water and sewerage charges at
DAWASCO represents the operator element of the water
and sewerage tariff billed to customers during the year.
The Corporation inherited a customer data base from the
previous City Water Services Limited. The data base had a
number of weaknesses namely:
• Preparation and issue of incorrect bills due to incorrect
meter readings and estimated consumption. Inaccurate
meter readings are attributable to faulty meters and
inability of the meters to cope with instances of low
water pressure in the network that occur from time to
time.
• Numerous instances were detected during the year of
active water connections that have not been billed.
• Numerous instances were noted during the year where
meter readings could not be matched to customer
accounts in the billing database. This indicates
instances of unrecorded revenue but has not been
quantified.
• Failure to achieve the Key Performance targets
stipulated in the Lease Agreement between DAWASCO
and DAWASA
The Corporation is required to achieve the Key
Performance Indicators (KPIs) and Key Performance Targets
(KPTs) agreed by Dar es Salaam Water and Sewerage
Authority (DAWASA) and DAWASCO as stipulated in the
Lease Agreement dated 2 September 2005 as amended and
restated as of 12 th December 2005.
During review of the Key Performance Indicators (KPIs) and
Key Performance Targets (KPTs) indicated that during the
year the Key Performance Targets (KPT’s) outlined in the
table below were not achieved by the Corporation.
