Water Recycling in the Food Sector

Unilever, a global consumer goods firm, opened their $72m factory in Durban in 2012. It’s their second largest dry food goods factory. To reduce the use of municipal water supply, the factory makes use of alternate sources of water, such as rainwater harvesting from a 22,000m3 roof and condensate recovery. In addition, it recycles most [...]

Water Reclamation for Reuse and Groundwater Recharge

Designed in collaboration with the US Environmental Protection Agency (EPA), the project also included the construction of a new reclaimed water distribution network and the construction of Rapid Infiltration Basins for groundwater recharge. At a project cost of $US344 million, financed primarily through municipal bonds complemented by a grant from the US EPA, it succeeded in [...]

Water Loss Management Program

The aim of the WLMP was to support smaller Local Water Utilities (LWUs) in their efforts to reduce leakage from their drinking water distribution systems. The batching of projects under WLMP also allowed eligibility with federal government funding criteria. Specialist knowledge and equipment were provided to LWUs in order to help identify, develop and implement [...]

Water Efficiency Audits of Steam Systems

To improve on water resource efficiency, CWW in 2010 launched a program focused on assisting business customers better understand how they can make steam systems more efficient. Steam systems were targeted because energy efficiency improvements are typically effective with a high likelihood of implementation. The program involves conducting site audits and the provision of training [...]

Reducing Water Losses in a Large Distribution Network

There is real pressure on the city to reduce and stabilize demand. To resolve the matter a number of measures were taken, these include: the replacement of water mains across the city, pressure management aimed at reducing night time pressures, active and passive leakage controls, continuous monitoring of reservoirs and towers, and other infrastructure upgrades. [...]

Water Demand Management Scheme

The action taken took the form of a comprehensive water demand management program with six goals in mind: reduce the high percentage of non-revenue water, reduce high static water pressures, reduce average daily demand, increase total revenue, provide constant and efficient service to consumers, and conserve water that was becoming increasingly scarce. At a project [...]

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 [...]

Water Authority Conservation Program

The security of supply is dependent upon reducing per capita demand, in particular those arising from landscape irrigation and evaporative cooling which make up 60% of the total demand. Subsequently, the Southern Nevada Water Authority (SNWA) instituted a number of aggressive water conservation programs from 2000 onwards that included monetary incentives, education and regulatory policies. [...]

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 [...]

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 [...]
