Pressure Management in Municipalities

To tackle the problem, a pressure management system was installed to control the pressure of the incoming bulk water, allowing for a reduction of supplied water to Sebokeng and Evaton during off-peak periods with a consequent reduction in leakage. The project was constructed using labor-based methods and a high level of stakeholder consultation to ensure [...]

Wastewater Reclamation to Meet Potable Water Demand

Part of a larger comprehensive program decades in the making to ensure water security for the city, direct potable water reuse in Windhoek actually started back in 1968. The scheme, in an effort to update and become more efficient, received an upgrade in 2002 in the form of a new plant designed to provide a [...]

Managing Evapotranspiration Using Quotas

Because overexploitation of groundwater across the basin is estimated to be 9 billion cubic meters annually, a program was developed to address the supply demand balance within the river basin, recognizing the impacts downstream. A 7-year program was developed (ending in 2011) that involved the implementation of an integrated water and environmental management strategy in [...]

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 [...]

Integrated Watershed Management

Kothapally village comprises 465ha of mainly cultivated undulating farmland with a population of 1,492 supported by semi-subsistence agriculture in the area. The level of resource degradation before project implementation was serious – characterized by low rainwater use efficiency, high soil erosion and a lack of soil stabilization or infiltration enhancement mechanisms. The project placed an [...]

Improved Water Distribution Management

?The Water Use Association (WUA) in the Lower Vaal area manages the distribution of irrigation water to hundreds of farmers over 1,120km of ageing canals and 1,873 abstraction points. The process needed to make it more efficient required difficult institutional reform combined with critical self-examination of operation and management practices. Coupled with a lack of [...]

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 [...]

Emergency Water Demand Management

The crisis situation at Gamka Dam can be attributed to several factors, namely, low rainfall, uncontrolled water consumption (up by 44% in six years), insufficient planning and the high cost attached to new water resource development options. More important than the contributing factors however was the reaction; by the time the town emerged from the [...]

Domestic and Business Retrofit Project

The initial aim of the program was to encourage residents of Sydney to consume less domestic water. Since then, Sydney Water has expanded the initiative to incorporate businesses, helping them to reduce their water consumption and to benefit from reduced costs. They did so by promoting the use of efficient devices, inspect mains infrastructure, reach [...]

Behavioral Change Initiative

?The project has shown that it is possible to deal with a shortage of water in an urban domestic setting, using a cost efficient, quick, ecological and contention free approach. Using a partnership approach, with funding coming through multiple sources (mostly through The European LIFE programme), the project focused on public engagement through the media, [...]
