Doosan Heavy Wins Sewage Treatment Contract in the UK

by with No Comment News

Doosan Heavy has announced that its UK subsidiary Doosan Enpure had recently been awarded the contract for the Guildford Sewage Treatment Works Relocation project by Thames Water, UK’s largest water and wastewater services company. Doosan Enpure partnered with BAM Nuttall to form a consortium for the project in which it will be participating as the main contractor. The project is valued to be approximately KRW 180 billion.

The Doosan Enpure consortium will be demolishing the existing sewage treatment works in Guildford, which lies southwest of London, and will be replacing it with a new sewage treatment facility built at a nearby site, one that is equipped with upgraded sewage and sludge treatment capabilities. Doosan Enpure will be taking on the overall engineering, procurement, installation and commissioning work. The project is scheduled to be completed by late 2026.


“This is truly significant as it is the first time we are participating as a main contractor for a project ordered by Thames Water, which is UK’s largest water and wastewater services company,” said Inwon Park, CEO of Doosan Heavy’s Plant EPC Business Group. He added, “We aim to successfully carry out the project by leveraging Doosan’s superior sewage treatment technology and will be using this as a basis to strengthen our foothold in the constantly growing global water treatment market.”

In 2019, Doosan Enpure was selected as a contractor for the AMP (Asset Management Plan) framework, a UK government-led fixed-term initiative. Through the initiative, the company is endeavoring to win more orders in this sector by engaging in numerous projects, such as the expansion and renovation of water and wastewater facilities in Yorkshire and the Midlands, in the years leading up to 2025.

SSEM secured $202 million Industrial Wastewater Treatment Plant Contract

by with No Comment News

Saudi Arabia’s Marafiq (Power and Water Utility Company for Jubail and Yanbu) awarded the contract to expand Industrial Wastewater Treatment Plant No. 8 (IWTP8), Phase 4.

The Project location is in Jubail, eastern region of Saudi Arabia.

The project has been awarded to Saudi based construction firm, Saudi Services for Electro Mechanical Works Co. (SSEM).

The value of signed contract is SAR 757,500,000 (USD 202 million).

As per the temrs of the contract, SSEM will expand the existing Industrial Wastewater Treatment Plant No. 8. The Phase 4 expansion will enable the plant to treat industrial wastewater with a 125,000 cubic meters/day of liquid waste in addition to its current capacity.

The project completion period is 36 months.

The expansion of IWTP-8 will use the latest technologies to enhance the capabilities to preserve the environment and ensure full commitment to the Royal Commission’s environmental regulations.

At present, in Jubail, Marafiq is having the total network length of approximately 1,200 km for sanitary and industrial wastewater. All wastewater is collected through a pipeline network will be delivered to the Industrial Wastewater Treatment Plant (IWTP8) and the Sanitary Wastewater Treatment Plant (SWTP9).

At present, IWTP-8 is having design capacity of 148,000 cubic meters/day and SWTP9 is having design capacity of 159,000 cubic meters/day.

SUEZ TO EQUIP WORLD’S LARGEST MABR WASTEWATER-TREATMENT SYSTEM IN CANADA

by with No Comment News

Suez Water Technologies announced that the Region of Waterloo (Canada) has selected SUEZ’s ZeeLung technology to equip what will be the largest Membrane Aerated Biofilm Reactor (MABR) system in the world at the Hespeler Wastewater Treatment Plant, in Ontario. The innovative technology will support the regional government’s objectives to deliver better water quality while improving nutrient removal, reducing energy and maximizing the treatment capacity and performance from existing assets.

“This is a first-of-its-kind project for Canada that will demonstrate ZeeLung’s benefits: the ability to quickly and easily upgrade existing wastewater treatment plants on a cost-effective basis, with little disruption to on-going operations,” said Kevin Cassidy, executive vice president engineered systems for SUEZ – Water Technologies & Solutions. “The technology allows customers to increase the treatment capacity of their plants, for a better water quality in a compact footprint while also reducing energy consumption.”

ZeeLung technology is used to upgrade conventional activated sludge plants for nutrient removal and capacity expansion. ZeeLung employs a gas permeable media to deliver oxygen to a biofilm that is attached to the media surface. Oxygen is delivered through the media by molecular diffusion, which is done without the use of bubbles. In conventional wastewater treatment, 60% of the energy used is consumed by blowers that deliver bubbles to provide the oxygen necessary for the biological process. With ZeeLung technology, oxygen is delivered without bubbles, which reduces the energy required for oxygen transfer by up to 4-times. This allows plants to significantly reduce their energy footprint while also increasing capacity and improving treatment quality.

The Region of Waterloo, in southwestern Ontario serves a total population of more than 600,000 people using its 13 wastewater treatment plants to process 180 million litres of wastewater per day. To meet the projected population growth, the secondary treatment process of the Hespeler plant has to be upgraded. The new contract follows an 8-month pilot which demonstrated the ZeeLung technology and refined the design for full-scale implementation.

When commissioned in 2021, the 9.34 MLD upgrade will be the largest implementation of MABR technology in the world.

National Water Company (NWC) takes up SAR204 Million Water and Wastewater Projects

by with No Comment News

The National Water Company’s (NWC) General Directorate for Water Services in Qassim region announced that it started the implementation of a number of key projects that aim at increasing wastewater services coverage, developing radical solutions for overflows and reducing the environmental impact of wastewater pollution, in addition to improving operational circumstances and supporting the water systems in the region, at a cost of more than SAR204 million.

Eng Abdulmuhsin Muhammad Al-Furaihi, General Director of Water Services in Qassim, said that the directorate is implementing a project for wastewater networks and domestic connections to the east of Buraidah city, costing more than SAR57 million, and comprising the laying of more than 55,700 meters of pipelines, main and sub-networks. Additionally, 3,225 house connections will be installed, with a total of 24,832 new customers benefiting from the project.

Al-Furaihi added “we are also implementing a project for laying wastewater networks in different areas of the city (phase three), costing over SAR87.7 million, comprising the laying of more than 88,000 meters of pipelines, main and sub-networks, in addition to the execution of some 3,916 domestic connections serving more than 30,150 new customers.” The two wastewater projects will save the region 540 wastewater tanker-trips.

The General Director said that work is currently in progress to implement a project for building an operational strategic reservoir with all its attachments east Buraidah, with a cost of more than SAR59.5 million and capacity of 50,000 m3/day in phase one, to enhance operation and boost the water storage systems in the city.
