Hamburg Wasser – KASHWASA and KUWASA

The project participants

  • International partners
  • German partners

KASHWASA

Kahama-Shinyanga Water Supply and Sanitation Authority (KASHWASA) (Shinyanga, Tanzania) produces and treats water from Lake Victoria in Northern Tanzania, conveys it through the transmission main of over 600 km and supply water in bulk to eight Water Supply and Sanitation Authorities and 170 Community Based Water Supply Organizations. The service areas include several Districts with a population of 1 Mio people.

KUWASA

Kahama Water Supply and Sanitation Authority (KUWASA) is supplied with bulk treated water from KASHWASA. KUWASA is located in Kahama Municipal in Shinyanga Region. Currently, Kahama Municipal has an estimated population of 308,296 people. The water service coverage for Kahama is 82% and its one of the top three Water Utilities in Tanzania with high performance.

Hamburg Wasser

HAMBURG WASSER is a group of public water and wastewater utilities providing water and sanitation services to more than two million consumers in the metropolitan region of Hamburg, Germany. There are two separate legal entities in the company – Hamburg Water Works (Hamburger Wasserwerke GmbH) and Hamburg Public Sewage Company (Hamburger Stadtentwässerung AöR) – they were combined in 2006 under one roof with a common aim, structure and procedures, as well as identical management for the first three hierarchical levels. The Federal State of Hamburg owns both companies.

Netze BW

Netze BW (Stuttgart, Germany) is the largest water supply company in Baden-Württemberg and ensures the supply of drinking water to the city of Stuttgart with its more than 600,000 inhabitants.

Capacity development on all aspects relating to drinking water supply

Improving the performance of the water supply network and optimising water treatment

The overall project goal is to establish a sound long-lasting cooperation in partnership between KASHWASA, KUWASA, HAMBURG WASSER, and Netze BW

The project

The overall project goal is to establish a sound long-lasting cooperation in partnership between KASHWASA, KUWASA, HAMBURG WASSER, and Netze BW.
The concrete goals and targets are the following:

  1. Improved operation and maintenance of drinking water infrastructure
  2. Management support and strategic planning

Improvement of water supply network performance

Water leakages in distribution networks are generally perceived as a waste of resources and damaging to the environment. During times of water scarcity, the topic of water leakage is prominent. With the increasing trend towards sustainability, economic efficiency and environmental protection, the minimization of water leakages is one priority of this partnership.

In addition, an initial rough analysis for the introduction and operation of energy generating measures (turbine operation) for energy recovery from the water supply network will be carried out by the peers to determine whether this is a viable and cost-effective option for KASHWASA.

Optimisation of treatment processes in the drinking water production

KASHWASA produces drinking water by collecting raw water from Lake Victoria and transport it to the water treatment plant where it is treated and then pumped as bulk water to KUWASA. The partners will jointly analyse and assess the water treatment facilities at KASHWASA’s to develop and implement an action plan for the optimisation of the treatment process as well as for the reduction of chemical use and energy consumption.

Development and implementation of a GIS unit

GIS is an essential tool for an efficient operation and management of water utilities. The peers from the GIS department in Germany will team up with their counterparts from KASHWASA/KUWASA to provide technical assistance in the development and establishment of a GIS unit and provide training and best practices in the application of the equipment and software.

Management support and strategic planning

In this area, the self-assessment of utility performance for the identification of baseline institutional performance is to be supported and an agreement of roles & responsibilitiesis to be concluded. The focus will also be on supporting the self-assessment of the performance capacity of the water supply networks and an exchange on strategic planning and benchmarking to define institutional development strategies.
