New build

Biwater are carrying out development works for a large-scale water and wastewater treatment contract in the cities of Erbil and Sulaimani. Works will alleviate the current strain on existing infrastructure and reduce the region’s reliance on dwindling groundwater reserves to deliver long-lasting environmental benefits. The development works benefited from a loan financed by UK Export Finance (UKEF). In 2016, the finance deal was awarded the Best Deals Award by Global Trade Review (GTR) and the Export Credit Agency Highly Commended Award by the Trade & Forfaiting Review (TFR). The current stage of works involves 'emergency works' alleviating water scarcity across the region, with a focus on extending the water supply network. Pipe installations are underway.

Jeddah

Saudi Arabia

New build

A reclamation plant built for Jeddah was one of the first of its kind in the country. The reuse facility was built to treat secondary effluent from the existing sewage treatment works to produce irrigation water, as well as water for limited domestic use as ‘greywater’. As such, it was important the treated water from the reuse plant meet all World Health Organisation (WHO) standards to be safe for human consumption, in any quantity. The scope of works included an off-site storage reservoir and the interconnecting pipework. The process design was based on in-depth laboratory testing.
