Use of Seawater in Dual Municipal Water Supply

The project to use seawater for flushing toilets was initiated 50 years ago, and has helped to ensure that the city is able to meet its water demands. Since its launch, the system has expanded and now comprises 45 service reservoirs, 40 pumping stations and over 1,400km of pipes with corrosion protection. The seawater is [...]

Reducing Business Risk through Municipal Leakage Reduction

The intervention to improve conditions involves a public-private partnership between several key players (industry, local government and funding agencies), and their attempt to reduce water risks, stress and costs, while increasing water supply to the municipality. This requires a high of buy-in from stakeholders, education and capacity building, repairs and reinvestment of audited ring-fenced savings [...]

Mine Water Recycling

The 2006 expansion provided the opportunity to change how water was managed on site and initiated a series of site interventions to reduce the amount of freshwater abstracted from Lake Argyle, replacing it instead with lower quality water mainly abstracted from mine dewatering activities. The project involved the construction of two dams to collect the [...]

Managing Water Towards Zero Discharge

?In 2010 Procter and Gamble (P&G) established the Planta Milenio manufacturing facility in the basin. In order to minimize business risk and environmental impact the plant was designed to minimize the volume of water that would be abstracted from the basin for business operations. The total groundwater abstraction of the site had the potential to [...]

Improving Water Availability through Wastewater Treatment

This project, implemented over a 10-year period, improves available resource through the capture and treatment of urban and industrial wastewater flows and returning them for direct or indirect re-use in irrigation. A key element to the project’s success was the enaction of policy and legislation that enforces the “Polluter Pays” principle, enabling waste water treatment [...]

Groundwater Recharge

?In order remedy the situation, attention was focused on the Omdel aquifer near the mouth of the Omaruru River which had the largest storage capacity at 150 000 000m3. Previous research had also identified that natural recharge in the system was reducing as a result of heavily silt-laden floodwaters clogging normal recharge pathways. The scheme [...]

Groundwater Conservation

The Government of Yemen, in collaboration with The World Bank, implemented the ground water conservation project in 10 of the 13 catchments in the country, with focus on sub-catchments where aquifer depletion rate was most critical. An integrated approach using a combination of supply side and demand side interventions was implemented to increase the available [...]

Aquifer Recharge with Stormwater

?As a result a number of strategies have been developed to address the supply demand imbalance and secure sustainable water supplies into the future. Recognizing that up to 90% of demand for potable water supply could be replaced with a non-potable supply, the City of Salisbury implemented the collection, storage and distribution of stormwater run-off [...]
