Design of a multi phase sewage treatment works serving the city of Sharjah in the UAE.

Halcrow has been continuously involved in the development of the Sharjah Main Drainage Scheme since 1969 when the proposed development plan for Sharjah was submitted.

The first main drainage contract was let in 1974. These substantial contracts included the construction of the first phase of the sewage treatment works which was commissioned in 1978. The continuing growth in the population of Sharjah has led to a need to provide additional treatment capacity at the existing wastewater treatment plant. The existing plant has been previously expanded under Phases 1-6 and will now be additionally expanded by Phase 7, to provide an additional 75 000 m3/day capacity to the existing 156 000 m3/day capacity.
