“We have 121 days left of usable water in our dams,” said De Lille at a briefing to drive home the city’s water crisis.

De Lille plans to write to Western Cape Environment MEC Anton Bredell, asking for the city to be declared a disaster area, so that it can institute emergency measures.

‘Crisis’

 These would include treating waste water even further to put it in the potable system, drawing water from the Table Mountain Group Aquifer and the Cape Flats Aquifer, and in the long term, an ambitious R15bn desalination project with Eskom that would cost R1.2bn in operating expenditure (LINK).

Djibouti-Djibouti: Design, construction and operation over 5 years of a seawater desalination plant (2014!)

Contract specifications

6.Contract description:

Under the contract, the aim is to construct a desalination plant in Doraleh for the population of the City of Djibouti. This contract entails the following tasks:
1. design, construction and operation of a desalination plant comprising:
a. installations for pre-treatment, reverse osmosis, re-mineralisation and disinfection, to produce 22 500 m3/day, with civil-engineering infrastructure designed to produce 45 000 m3/day for a future development phase;

b. a seawater pumping station with an approximate capacity of 100 000 m3/day;

c. a pumping station for transferring drinking water to the [

Three firms pre-selected for desalination project (Djibouti)

Following a call for tenders issued in 2014, the European Union and the l’Office National de l’Eau et de l’Assainissement de Djibouti (ONEAD)


To overcome the overexploitation of the aquifer in the capital, PEPER calls for the construction of a desalination plant with a capacity of 22,500 m3/day, fed by a wind farm with a pumping station with a capacity of 100,000 m3/day. Some nine kilometres

Sweet water for Meerensee area (South Africa)



THE desalination plant at Alkantstrand is already in production and by the time it is commissioned on 1 February, it will supply enough water to supply Meerensee, Mzingazi and Mbonambi.

Speaking at a drought crisis meeting in Richards Bay on Tuesday, Muneka Paradzai, Project Manager at the Department of Water and Sanitation (DWS) said the salt water to drinking water plant was already producing 3.5 megalitres (Ml), which would climb to 10Ml in full production.

‘Testing is being done and the taste is excellent – slightly sweeter than consumers are accustomed to.

‘The water from the plant will be sent to the Meerensee [

Bimetallic Metal-Organic Frameworks Derived Porous Carbon Nanostructure for High Performance Membrane Capacitive Desalination

Membrane-based capacitive deionization (MCDI) is a novel method of desalination that promises to alleviate the stress of water shortage. Current techniques show limited efficiency in salt removal and experimental results suggest that an improvement in electrode materials could be the cornerstone of MCDI. In this study, bimetallic metal-organic frameworks (BMOFs) have been used as precursors to develop porous carbons for MCDI electrodes. BMOFs are a unique class of MOF that possess two types of metal ions with properties dependent on the ratio of the metal ions. In our work, we have synthesized a series of BMOFs with different molar [
