Cape Town

This Innovative Technology Harvests Water from Cooling Towers.

To a researcher like Kripa Varanasi, an associate professor of mechanical engineering at MIT, a big nuclear power plant similar to the one that generates electricity near Cape Town, South Africa, is a fountain of water just waiting to be tapped.

The 1,800-megawatt Koeberg Station drinks in water from the nearby Atlantic Ocean and uses it as part of its thermal cooling cycle. Just as in other industrial settings, cooling towers are an inherent part of the power plant’s steam cycle.

As the reactor heats ultra-pure water to create steam to spin a turbine and generate electricity, a cloud [

Desalination for Cape Town – Numbers and Facts – South Africa




3. What about in South Africa?
In South Africa desalination is used quite widely by mines to clean up polluted mine water and acid mine drainage. Small to medium-scale desalination has also been used in coastal towns during times of drought. Six municipalities are currently using small-scale reverse osmosis plants to desalinate water for bulk water supply.

Mossel Bay has a medium size desalination plant capable of producing 15 million litres of potable water per day but the plant is currently on standby as the dams in the area are full. Standby mode requires continuous maintenance to keep the plant [

Eskom’s Koeberg nuclear power station turned on desalination plant

Eskom’s Koeberg nuclear power station today turned on its temporary mobile groundwater desalination plant, which will ease the pressure on the City of Cape Town’s water supply. “When the City of Cape Town called on the people of the Western Cape to address the water issue, we had to respond with a sustainable solution as a responsible corporate citizen,” Velaphi Ntuli, Koeberg Power Station manager said. Ntuli explained: “The desalination plant is part of Koeberg’s three-pronged water management strategy to address the current water shortages in the Western Cape while ensuring that the plant is able to provide safe [

Monwabisi desalination plant starting side preparation – Cape Town – South Africa

The Monwabisi desalination plant is one of seven projects earmarked as part of the first phase of the City of Cape Town’s Additional Water Supply Programme. Site preparation is currently under way. “It is anticipated that the Monwabisi plant will produce a total of seven million litres of drinking water per day which will be fed into the water reticulation system to supplement current supply from the dams and other water sources. “A nine-week construction period is planned for the completion of the first phase comprising two million litres. The first drinking water generated by the desalination plant is [

Desalination: Cape Town’s solution to water shortages – South Africa

Minister of local government‚ environmental affairs and development planning in the Western Cape, Anton Bredell, says the province has been managing drought conditions in some parts of the region since 2010. “Three years of below-average rainfall have exacerbated the situation and despite proactive measures like the implementation of water restrictions and programmes to clear the Berg River of alien vegetation‚ the reality is we are faced with a dire situation.” Inspired by the Target 140 Campaign implemented in South East Queensland, Australia, Cape Town embarked on reducing water usage. So far residents’ water usage has dropped below 100 litres [

Dams at 38.5%, desalination timeline remains unclear – South Africa – Cape Town

Total storage in the six major dams supplying Cape Town is down by 0.1% to 38.5% (pdf). That’s a loss of around 519-million litres — slightly less than the average day’s consumption in the city.

Cape Town’s dam levels

Leading the decrease was everyone’s favourite underperforming dam — the Theewaterskloof. The largest reservoir in the Western Cape again struggled to hold its level, dropping from 27.8% last week to 27.3% this. At the same point last year, it was 51% full. The Steenbras Upper Dam dipped to 100.4% — shedding 1% — while its Lower neighbour gained 1.1% overall. [

Cape Town scales up water augmentation programme – South Africa – Cape Town

The City’s large-scale augmentation procurement programme involving desalination, aquifers and recycling, among others, is unprecedented in scale.Yesterday, the City initiated Phase 1 of its critical water shortages disaster plan, with water rationing under way as dam levels stand at 38.5% and useable water at 28.5%. The City said yesterday that the unprecedented procurement programme is under way to help supplement water supply during this drought crisis. It is foreseen that between 130 and 240 million litres a day will be at some stage of production between December and May 2018. This includes land- and sea-based desalination, water reclamation and [

“It is illegal to sell water” Water and Sanitation Department spokesman Sputnik Ratau said – South Africa – Cape Town


.

Meantime, with water rationing underway, and dire warnings of “day zero” when supply will run completely dry, enterprising profiteers are taking advantage of the shortage. Water restrictions, threats of prosecution and a sense of panic have some residents willing to pay for alternative water supplies for gardening, swimming pools and flushing toilets.

Water and Sanitation Department spokesman Sputnik Ratau said the government was the custodian or trustee of water resources, including dams, rivers, lakes, pans, wetlands and groundwater. “It is illegal to sell water. The only case in which water is sold legally is as bottled water,” he [
