Qatar’s Public Works Authority (Ashghal) has awarded the local National Industrial Contracting Company (NICC) the QR 154.98m ($42.6m) third construction package at its sewage treatment plant in south Al-Khor.

The contract involves the construction of 31 kilometres of vitrified clay sewers and 7.5km of trunk sewer.

It also includes construction of 1,200 manholes, 185 of which will be located in shafts used for micro-tunnel sewer installation and 1,700 house connections to provide ground access to entire sewerage network.

The processed sewage will be used for irrigation around the city. The project is scheduled for completion by Q3 2012.

The project is part of a larger scheme by Ashghal to install new sewage treatment works to serve the City of Al-Khor.

The treatment works will serve Al-Khor’s expected population of 36,000 people.

NICC is a subsidiary of the local Nasser bin Khalid Group (NBK).
