(2) My Department has encouraged recycling of effluent by municipalities more especially in water stressed areas of our country. Recently Lephalale LM has signed a contract with Resource Generation, which plans to open Boikarabelo Mine in Limpopo. Under the terms of the agreement, Resource Generation will build, operate and maintain a wastewater treatment facility at Marapong for the Boikarabelo mine site. The treated water will be pumped to the firm's planned Boikarabelo mine site through a new pipeline. Resource Generation will pay for the Marapong wastewater treatment plant upgrade works and expansion works to extend capacity to 4Ml a day, increasing to a daily 16Ml by January 2017.
Also in Lephalale, Waterberg Coal Company entered into an agreement with the Lephalale Municipal Council (LMC) to take over the management and operation of the Paarl WWTW for the purposes of supplying water to the Waterberg Coal Projects (WCP). The facility has a treatment capacity of 10 million litres per day.
