Leakage Reduction in Primary Schools

The significance of the project is in its simplicity and cost-effectiveness, if only because it can be easily replicated at thousands of other schools and public buildings leading to huge water savings. More significantly, much of the “wasted” water that was targeted by this type of project would otherwise be lost to evaporation and evapotranspiration [...]

Leakage Reduction in a City

In 2008 a joint venture of Acwa Power and Suez Environment were awarded a seven-year water services management contract, under which a number of measures have been implemented to reduce unaccounted for water. The project was divided into two pilot stages, the first targeting the implementation of Pressure Regulating Valves in 16 district zones, and [...]

Metering of Non-Revenue Water

?In 2010 EMM launched, as a result of the significant gap, a campaign to consolidate multiple connections into single metered supplies. While the replacement of meters was the main feature of the project, other important components included identifying illegal connections and repairing leaks. The project ended up being the overall winner of the South African [...]

Irrigation Scheduling in Grape Farming

In order to minimize water use Shelanu Farm, a small but highly intensive farm  using modern technology, optimized its water irrigation scheduling based on data automatically received from soil moisture (capacitance) probes and analysis using a sophisticated computerized monitoring and management system. Soils around the farm vary considerably and the automated system allows variable irrigation [...]

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 [...]

Irrigation Network Renewal

The Project involved real-time monitoring and control of flows, lining the main channel, installing sprinkler and drip irrigation system and a central data repository of irrigation system flows and abstractions. The water entitlement aspect of the project was developed to help transition from inefficient practices and low value crops to efficient practices and higher valued [...]

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 [...]

Direct Dry Cooling in the Power Sector

Matimba Power Station is the largest direct-dry-cooled station in the world, with an installed capacity of greater than 4,000MW. It makes use of closed-circuit cooling technology reducing water consumption to around 0.1 liter per kWh of electricity distributed; this, in comparison to wet cooling system power stations use 1.9 liters per kWh is a significant [...]

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 [...]

Advanced Pressure Management

The leakages resulted in very high water use in most properties and high levels of non-payment, since the customers couldn’t afford to pay for new taps and toilet fittings, let alone their high water bills. The Khayelitsha Pressure Management Project was therefore commissioned in 2001 to improve the level of service to the community by [...]
