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 [...]

Groundwater Conservation

The Government of Yemen, in collaboration with The World Bank, implemented the ground water conservation project in 10 of the 13 catchments in the country, with focus on sub-catchments where aquifer depletion rate was most critical. An integrated approach using a combination of supply side and demand side interventions was implemented to increase the available [...]

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 [...]

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 [...]

Advanced Pressure Management

The leakages resulted in very high water use in most properties and high levels of non-payment, since the customers couldn’t afford to pay for new taps and toilet fittings, let alone their high water bills. The Khayelitsha Pressure Management Project was therefore commissioned in 2001 to improve the level of service to the community by [...]
