Major southwestern city water supplies – Colorado

For Phoenix, it’s water is supplied through surface water sources. The northern end of the city gets water from the Central Arizona Project, which is supplied by the Colorado River and Lake Mead. The southern end gets its water from the Salt River Project.

Las Vegas gets 90% of its water from the Colorado River and Lake Mead and 10% from groundwater sources. The groundwater supplies up to 25% during the hot summer months when demand is high. In 1971 Las Vegas with a population of 126,000 residents began getting water from Lake Mead.

Today, Las Vegas has swelled to 2 million residents and increases on weekends by an additional 3 million people. Las Vegas gets a 300,000-acre feet allotment from the Colorado River each year. They only use about 240,000-acre feet and bank the rest in the groundwater table.

Proudly South African hydrogen breakthrough with Shell’s backing – Johannesburg

Hydrox Holdings engineers, based in Strydompark, Randburg, have shot the lights out with a unique hydrogen electrolyser leap forward that deploys innovative patented and already trade-marked local technology that facilitates the use of far fewer components and generates significant cost savings.

This innovative technology promises to lower the production price of hydrogen and serve as a disruptive hydrogen economy enabler.

The homegrown divergent electrode flow through (DEFT ™) technology allows electrolysers to operate without membranes at higher temperatures, which results in greatly improved electrical efficiencies.

Midkiff farmer, Encore Green team on produced water project – Texas

Amid talk of trying to expand the market for the water that’s produced alongside crude oil and natural gas beyond the oil patch, one company is putting its words into action.

Wyoming-based Encore Green Environmental had visited the Produced Water Society Permian Basin’s conference last August to promote its idea of pairing the oil and gas and agriculture industries, sparking the interest of Cody Wilson and his S&S Wilson Farms in Midkiff.

Today, the two are moving forward with a project that will treat produced water for use in irrigating the cotton on Wilson’s farm as well as producing electricity that can be sold back into the electric grid.

Solar-driven water desalination system for Maasai villages

A pilot plant was installed at a saline well in the Tanzanian Maasai village of Ndedo and supplies the population with 2000 litres of drinking water per day.

The plants are complete systems in which the water is cleaned of dirt particles, bacteria and viruses in preliminary stage and treated with self-generated chlorine in a post-treatment stage for sterile storage in a water tank.

The core of system is based on the membrane process of electrodialysis.

Solar-driven water desalination system for Maasai village, Tanzania – Tanzania

Together with nine other European project partners, Phaesun is developing innovative desalination systems based on electrodialysis technology as part of the EU development and innovation project REvivED Water.

In February 2020, a pilot plant was installed at a saline well in the Tanzanian Maasai village of Ndedo and supplies the population with 2000 litres of drinking water per day.

The plants are complete systems in which the water is cleaned of dirt particles, bacteria and viruses in a preliminary stage and treated with self-generated chlorine in a post-treatment stage for sterile storage in a water tank. The core of the system is based on the membrane process of electrodialysis. In contrast to conventional desalination technologies (thermal or reverse osmosis), electrodialysis is particularly low-maintenance and is well suited for solar power supply due to its low energy consumption. Thus, a completely self-sufficient system could be developed, which does not require any additional infrastructure or power supply.

Ontario Teachers and UTA acquire TIF’s Sydney desalination plant stake – Ontario

Ontario Teachers’ Pension Plan Board and the Utilities Trust of Australia (UTA) have increased their ownership stakes in the Sydney Desalination Plant (SDP) to 60% and 40% respectively.

Ontario Teachers and Morrison & Co, on behalf of UTA, said they have increased their holdings in SDP with their acquisition of The Infrastructure Fund’s (TIF) ownership stake in the plant. Financial details were undisclosed.

SPD, which is Sydney’s only non-rain dependent source of drinking water, supplies up to 15% of the Australian city’s needs.

GWCL Asks Teshie Desalination Plant To Operate At Full Capacity – Ghana

The Ghana Water Company Limited (GWCL) has asked the operators of the Teshie Desalination plant to, as a matter of urgency, operate at full capacity to help improve the water supply situation in the country.

The plant, which was shut down for about a year over some technical and operational challenges, resumed operation on March 18, this year.

Currently, it produces an average of 40,000 cubic metres of water daily instead of the overall capacity of 60,000 cubic metres a day.

Water & Wastewater Workers Considered Essential During COVID-19 Outbreak – California

10 workers are quarantined inside the Claude Lewis Carlsbad Desalination Plant in Carlsbad, California for the next three weeks.

The workers are monitoring and adjusting gauges and switches, watching for leaks, and completing other tasks needed to safeguard San Diego County’s only significant local source of drinking water. All 10 volunteered themselves. The Carlsbad plant is home to 40 employees overall, reported the San Diego Tribune.

The request for volunteers was a precaution against the spread of COVID-19, reported the San Diego Tribune.

Rs 12.13 bn released for CPEC projects under PSDP 2019-20 – Pakistan

The government has so far released development funds of over Rs 12.13 billion for various development projects of China Pakistan Economic Corridor (CPEC) under its Public Sector Development Programme (PSDP) 2019-20.

According to latest data issued by the ministry of Planning on Thursday, the government had allocated Rs 18 billion for around 20 projects of CPEC for the year 2019-20.

For construction of KKH phase-II Havelian-Thakot (118.057 M) part of CPEC, the government released Rs 2 billion out of total allocation of Rs 2.238 billion. The government has also released Rs 1.8 billion for preliminary design for up-gradation of main line (ML-1) and establishment of dryport near Havelian under the CPEC.

Dh3.4m prize offered to improve water desalination – UAE

Entrepreneurs are being offered Dh3.4 million in prize money to help reduce the amount of brine produced at desalination plants.

The UAE government has combined with the private sector to launch Rethink Brine in an effort to solve the issue.

Officials hope the challenge will encourage more researchers and scientists to develop new ways to tackle the problem.
