Germany-headquartered PWT Wasser and Saudi Arabia's Al-Masar Al-Hadeeth signed a contract on 14 October 2026 to build a wastewater treatment plant in Jizan, in southwestern Saudi Arabia, serving the King Abdullah District at a treatment capacity of approximately 11,356 cubic metres a day (MEED). The deal, awarded by the state-owned National Water Company, is valued at approximately $20m and uses membrane bioreactor (MBR) technology to treat municipal wastewater (MEED).

What happened
Reporting on 14 October 2026, MEED said Germany's PWT Wasser and Saudi Arabia's Al-Masar Al-Hadeeth have signed a contract to build a wastewater treatment plant in Jizan, in southwestern Saudi Arabia, that will serve the King Abdullah District (MEED). The plant will use membrane bioreactor (MBR) technology to treat municipal wastewater and is being built for the state-owned National Water Company (MEED).
The contract is valued at approximately $20m and covers the treatment plant, sludge treatment facilities, pumping stations, wastewater collection facilities and associated sewage networks (MEED). PWT Wasser is a subsidiary of Saudi Arabian pipe and water-infrastructure manufacturer Amiantit, and according to regional tracker MEED Projects the Jizan award is PWT Wasser's first major water infrastructure project in Saudi Arabia (MEED).
The Jizan contract is part of Saudi Arabia's wider expansion of wastewater treatment infrastructure. In 2025, Sharakat selected Alkhorayef Water & Power Technologies as the preferred developer for a separate public-private-partnership project in Jizan comprising a cluster of 12 small-scale sewage treatment plants with a combined treatment capacity of 74,700 m³/d and individual plant capacities between 1,800 and 15,000 m³/d; that $150m scheme also involves laying 166 km of collection pipelines, tanker discharge points and effluent connections, and as of August construction works had yet to commence (MEED).
Specification read
In buyer units, the reported Jizan plant sits at 11,356 m³/d, which is 11.356 MLD; on a population-equivalent basis that is roughly 75,700 people at the 150 litres per person per day planning figure often used for municipal sewage, though the source does not report influent BOD or COD so any organic-load design check has to be confirmed against the tender documents (MEED). Because the contract specifies MBR technology, the project sits at the biological stage of a typical municipal train — screening and grit removal upstream, an MBR basin with submerged membranes in place of a separate clarifier, then tertiary polishing and disinfection before reuse or discharge; the contract also covers sludge handling (MEED). For a reader running a similar 10–12 MLD municipal plant on the same feed class, the deal confirms MBR is the technology of choice for new Saudi National Water Company tenders in this size band, and that integrated delivery (treatment plus collection networks, pumping and sludge) is being packaged in a single award, which is the scope profile you should set up in an enquiry for Mbr Membrane Systems and Integrated Sewage Treatment packages, while a Municipal plant profile in the 10–12 MLD class is the closest reference point for sizing blowers, membrane area and sludge handling.
