Water Recycling in Paper Production

In order to minimize business costs and water demand MEPCO developed an on site water recycling process. This involved the installation of screens, drum filters, dissolved air flotation units and gravity filters. The company also installed an effluent treatment plant. At a capital cost of US$5,700,000, funded entirely by MEPCO, plant water demand reduced from [...]

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 [...]

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. [...]

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 [...]

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 [...]

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 [...]

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 [...]

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 [...]

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 [...]
