Qatars Public Works Authority (Ashghal) will not tender the engineering, procurement and construction (EPC) contract for Musaimeer Pumping Station near Doha until early 2015.
The tender issue date was originally scheduled for 17 August 2014.
Fifteen companies submitted documents for prequalification in August 2014, after the deadline was postponed from 30 June.
Ashghal has not released the shortlist of prequalified companies.
Work was scheduled to commence on the project in April 2015 and be completed in 2016.
The station, near Hamad International airport, will provide surface water and ground water drainage for southern Doha. It will have a capacity of 2 cubic metres a second (cm/s), and a maximum of 20 cm/s. The scope of works includes the construction of the proposed pumping station and 7 kilometres of marine outfall pipelines.
US-based CDM Smith is providing consultancy, design and construction supervision services on the project.
Ashghal is investing heavily in water infrastructure, with megaprojects such as the Water Security Mega Reservoirs project and the Inner Doha Resewerage Implementation (Idris), both due for contract awards. Smaller projects in the tendering process include Facility D IWPP, Al-Dhakira sewage treatment plant, awarded in December, and an expansion of the water treatment plant for Doha Industrial Area.
