/0 Comments/in , , , /by

As part of the International Water Association (IWA) World Water Congress & Exhibition held from September 11th to 15th, 2022, experts from the PrimeWater Consortium (EMVIS S.A & EOMAP), DHI Water & Environment, Australian Water Partnership (AWP) and African Water Association (AfWA) organized on September 12th, 2022, a session themed “Earth Observation Technologies for Water Management: Building a Community of Practice” to give a background on the Earth Observation (EO) Community of Practice (CoP) and showcase the uses and applications of EO in water management in different cases and contexts. This workshop allowed to develop a call to action on what can be done practically in terms of Knowledge, technology, regulation, etc. for addressing the barriers that were previously identified and creating opportunities for the uptake of earth observations tools and services.

CAN BRANDED KIOSKS IMPROVE REVENUE COLLECTION AT WATER POINTS IN GHANA?

/0 Comments/in , , , /by

In Ghana, most water point revenues are consistently below their estimated potential because vendors do not fully enforce pay-as-you-fetch tariffs. Low revenue collection undermines the ability of water systems to cover all maintenance and operating expenses. Aquaya evaluated whether installing branded kiosks at rural water points could increase revenue collection. In the five months following kiosk installation, daily water point revenues increased by a median of 51% or 1.1 GHS (0.2 USD). Revenue increases were very variable across sites, indicating that this intervention is not equally effective in all settings.

SHARE WATER Issue 12

/0 Comments/in , /by

This twelfth issue of AfWA Technical Journal addresses water security and the mechanisms/technologies to implement for universal access to water and sanitation for African populations, including a case study of the NGO Eau et Vie in Abidjan over the five years of intervention from 2016 to 2021. This study explains how to activate institutional and technical levers to enable vulnerable populations in disadvantaged neighbourhoods to have access to drinking water at lower connection costs. This innovative approach could help reduce unbilled water while giving economically weak populations back their dignity. A success story from the Chairperson of the Kenya Professional Women’s WASH Network, Dr. Leunita SUMBA, PhD on her commitment to women’s leadership and gender is also highlighted in this issue.

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

/in , , , /by

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.
