NEW – Water Free Milk Powder Factory

The project achieved a reduction in water abstraction from the initial 2 000 m3 per day to 0 m3 per day by treating the condensate to a potable level and re-using it in the manufacturing process. Residual wastewater is treated and utilised for cooling and cleaning. The project was driven by the need to protect [...]

NEW – Maximizing water reuse at a brewery

Since 2008 the plant has been under pressure to reduce its water use. Firstly to reduce the overall cost of water that was as high as $3.05 per m3, and secondly to help SCC lower its water use of water per beer ratio under 3.5 hectolitre per hectolitre (Hl/Hl) and meet the goals of the [...]

Water Reuse in the Power and Steel Production Sector

In order to reduce the combined water footprint of the sites, the power plant cooling system has been improved to reduce freshwater demand. Blowdown water that was previously discharged to the ocean is now transferred to the steel plant. In addition, wastewater from the steel facility is being treated for reuse in the power plant [...]

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 [...]

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 [...]

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 [...]

Improving Water Availability through Wastewater Treatment

This project, implemented over a 10-year period, improves available resource through the capture and treatment of urban and industrial wastewater flows and returning them for direct or indirect re-use in irrigation. A key element to the project’s success was the enaction of policy and legislation that enforces the “Polluter Pays” principle, enabling waste water treatment [...]

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 [...]
