Oman Wastewater Services Company (Haya Water) is preparing to award a contract in early 2015 for package two of a wastewater network extension project in Seeb.

The local Galfar Engineering & Contracting is the low bidder among the five companies that submitted proposals, with a price of RO21.5m ($56m). Gulf Petrochemicals Services & Trading, also local, is the second-lowest bidder, with RO25m.

The work involves surveying, and the provision, installation and commissioning of gravity sewer networks and connections to houses and existing networks in zones 2,3,5,7 and 8. It also includes monitoring systems for the sewers constructed.

The bidders are:

  • Al-Wataniyah United Engineering Company (local) – RO25m
  • Consolidated Contractors Company (Greece) – RO34m
  • Galfar Engineering & Contracting (local) – RO21.5m
  • Gulf Petrochemicals Services & Trading (local) – RO25m
  • United Gulf Construction Company (Kuwait) / Gharbia Enterprises (local) – RO29m

Haya Water is planning similar sewer extension projects across Greater Muscat as it aims to increase the percentage of residents linked to wastewater networks from 19.4 per cent in 2013 to 93.1 per cent in 2025.

Haya Water has been responsible for wastewater services in Greater Muscat since 2006 and all of Oman since 2014. It plans to invest a further RO1bn in new water schemes in the sultanate until 2018, and RO1.7bn by 2025 in order to improve connection and wastewater treatment rates.
