MajiData is the pro-poor database of the Kenyan water sector covering all urban low income areas in Kenya. A comprehensive data collection exercise started in 2009 and ended in 2011. More than 1800 urban low income areas found in the 212 cities and towns of Kenya were mapped and captured. In 2016 the decision was made by WSTF and WASREB not to only update MajiData but rather to set-up a modern database that will be connected to all existing ICT-tools of the sector institution with the support of GIZ.

MajiData presents key information on the Kenyan water sector with a focus on service delivery in urban low income areas. MajiData presents three key aspects:

  • Updated maps of all regulated water utilities in Kenya
  • Maps of all low income areas within the service areas of the regulated water utilities in Kenya

Performance of utilities:

WASREB has the mandate to monitor and regulate the performance of the Kenyan water utilities to protect the interest and rights of consumers. Benchmarking and performance ranking are key in facilitating performance improvement through competition and increases the level of transparency.

  • Key performance indicators: WASREB reports annually on the performance data of the utilities on the basis of nine key performance indicators: Water Coverage, Drinking Water Quality, Hours of Supply, Non-Revenue Water reduction, Metering Ratio, Staff Productivity, Revenue Collection Efficiency, O+M Cost Coverage and Personnel Expenditure as a percentage of O+M costs.
  • Corporate Governance: WASREB monitors the compliance of the water utilities to the corporate governance guidelines.
  • Pro-poor indicator: WASREB will soon present an indicator to monitor the level of service delivery in the low income areas within the utilities to stimulate better services for the urban poor.


The Water Sector Trust Fund has financed many projects across all 47 counties in Kenay. The focus is on water services and water resources management for the underserved areas.

  • Georeferenced information on all infrastructure that was built or rehabilitated with financial support by the Water Services Trust Fund implemented by the Water utilities in Kenya.

The overall goal of the MajiData is to contribute to a progressive improvement of water and sanitation services in Kenya’s urban low income areas through transparency.

MajiData is a joint initiative of the Water Services Regulatory Board (WASREB) and the Water Sector Trust Fund (WSTF) with the support of GIZ.

During the 2007 Annual Water Sector Conference, the need to carry out a pro-poor mapping exercise in order to collect data on the urban low-income areas was identified as being one of the priority water sector undertakings for 2008. Soon after the conference the Ministry of Water and Irrigation requested the WSTF to develop a pro-poor urban database covering all urban low income areas in Kenya. In October 2008 the data collection tools and other measures to prepare for a country-wide data collection exercise were finalised. The creation of the initial MajiData team and the testing of the data collection tools were completed in December 2008. Early 2009 MajiData became part of the H2.0 initiative. The data collection exercise started in February 2009. The exercise was completed in March 2011. With the support of GIZ, MajiData was officially launched in December 2011.

The MajiData website provides various kind of resources on the Kenyan Water Sector with a focus on urban low income areas including:

  • General data
  • Interactive maps
  • Information on national, county, water utility and low income areas level
  • Projects funded by WSTF
  • Performance reports of the Kenya water utility
