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 Optimization in the Mining Sector

The site's water withdrawal is restricted to 5,794,000m3. In order to continue expanding its operations without relying on additional water resources, Lomas Bayas investigated opportunities to improve its water efficiency, including replacing the original leach pad sprinkler system with a drip system that significantly reduced the water lost to evaporation. At a project cost of [...]

Regional Water Conservation Program

?In the year 2000 the SWP, covering a service area of 1.3 million people, implemented a program promoting a per capita reduction in water use by 1% per year for ten years. Implementation of the program consisted of various measures including but not limited to: low flush and low flow home utilities, and rebates to [...]

Wastewater Reclamation and Reuse Network

?In the late 1990s Singapore initiated a program to become increasingly self-sufficient in its water supply. One component of the program, called NEWater, involves the collection of treated wastewater flows that would have otherwise been discharged to the ocean. Between 2002 and 2010 the program further established four NEWater plants with a capacity of 500,000m3/day. [...]

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 Strategy

Key to managing demand has been facilitating behavioral change in water use and consumption. The campaign to manage demand in Singapore is known as the “3P approach” and encourages everyone (People, Public, Private) to take ownership of water resource management. Also central to this approach is the Active, Beautiful, Clean Waters (ABC Waters) Programme, which [...]

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 [...]

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 [...]

Pilot Low Cost Irrigation Scheduling

An investigation was undertaken to find a solution that farmers could implement into their farming methods in order to reduce water consumption and then, in the future, seek a scaling up of that strategy. Tensiometers were trialed and made attractive to farmers through a structured field test, the results of which could then be used [...]
