Spanish/local team wins Egypt wastewater treatment deal

10 June 2025

Spain’s Acciona and the local DHCU have been awarded a €35m ($40m) contract by the Construction Authority for Potable Water and Wastewater (CAPW) to manage the operation and maintenance of phase two of the Gabal El-Asfar wastewater treatment complex in Egypt for eight years.

The contract involves rehabilitation and upgrade works across two plants within the complex, each with a treatment capacity of 500,000 cubic metres a day (cm/d).

In 2022, Acciona and DHCU were awarded the contract for the operation, maintenance and enhancement of phase one of the plant, which has a capacity of 1.5 million cm/d.

In 2013, Acciona, with local firm Hassan Allam Construction and Germany's Passavant, was awarded the contract to construct the Gabal El-Asfar wastewater treatment plant. It was designed to handle 500,000 cm/d of wastewater and was completed over a four-year period.

Acciona has also partnered with CAPW to manage the water infrastructure for the upper-level supply network in New Cairo, a satellite city located approximately 30 kilometres east of the capital. This project involves sourcing water from the Nile River, transporting it to a drinking water treatment facility, and ensuring its treatment and storage before distribution to consumers.

Gabal El-Asfar is said to be the largest wastewater treatment facility in both Africa and the Middle East, and ranks as the third largest globally in terms of treatment capacity, processing 2.5 million cm/d to serve the eastern regions of Cairo – home to approximately eight million residents.
