This eleventh issue of the African Water Association’s semi-annual bilingual Technical Journal “SHARE WATER” explores innovative and good practice solutions to build resilient and sustainable African cities. Thus, the various articles proposed, including a brilliant case study on sludge recovery practices for a circular economy in Senegal, focus on the steps to be taken to achieve inclusive sanitation at the scale of cities in Africa. In addition, alternative solutions to water stress are proposed for better management of water resources: the Windhoek wastewater reuse model, the intercommunality underpinned by the ATPC (Community-Led Total Sanitation) approach which leads to the establishment of a water and sanitation technical service in a municipality in Niger, Molecular Bi-Orientation for high-quality PVC pipes that comply with international standards, the production of drinking water from ambient air or the treatment of water with solar energy in four West African countries.

Innovative smart metering system for water

The using of traditional water meters often leads to difficulties like long collection period, low collection ratio and high Non Revenue Water. Smart Water Meters is a brilliant system to overcome these difficulties. For example, in Zambia the performance increased to 65% after pre-paid meters installation by National Water and Sewerage Corporation (NWSC). Benefits of smart metering system are : compatibility with Africa Water Utilities, no more historical debt, cash flow improvement, automatic data collection, customer persona, efficiency improvement.
