Wastewater network and treatment plant contracts to be awarded in Oman, early 2013

Sponsored by

A four-year USD$75.1 million contract has been awarded for the modernization of Oman’s wastewater network in the Amerat Western Area, part of a series of contracts being awarded in the country.

Haya Water awarded the first construction contract in the Al Amerat Water Reuse Project - Contract A2 - for installation of sewer and treated effluent pipelines to a joint venture comprised of The Arab Contractors and National United Engineering & Contracting.

The contract is expected to deliver 23 km of sewers, 140 km of laterals and riders, 7 km of treated effluent line installation and 43 km of House Connections encapsulating 2,900 properties. This project will be handed over to Haya Water in August 2016.

The Muscat Water Reuse Project Master Plan has divided the Muscat Governorate into five sewerage catchments for project implementation: Al Amerat, Muttrah, Bausher, As Seeb, and Quriyat.

The Al Amerat Waste Water Project, undertaken by Haya is a component of this Master Plan. This project provides sewerage and Water Reuse treatment infrastructure for Al Amerat and Al Hajir areas (the Project Area), both of which are located in Wilayat Al Amerat.

The Al Amerat Water Reuse Project will be implemented in stages, as demand for sewerage services increases with population growth and development.

The initial (Phase 1) implementation will include gravity sewer networks, sewage pumping stations and sewage rising mains, a water reuse treatment plant and treated effluent distribution networks, which will be provided through multiple contracts and intended to be completed by 2016.

Future implementation (after Phase 1) will include extensions to the sewer and treated effluent networks, additional pumping stations and rising mains, and expansion of pumping station and treatment plant capacities.

The CEO of Haya Water, Eng. Hussain Hassan Ali Abdul Hussain said that Contract A2 is the biggest of the three network construction contracts identified in the Project, and when completed, will cater to nearly 2,900 properties in the western area of Wilayat Al Amerat.

He said: "The wastewater network aims at gradually reducing, and finally eliminating, the current complex system of transporting waste water from a property's septic tanks via tankers, thereby benefiting the population, and simplifying the collection of revenues from the various properties."

In early 2013 Haya Water plans to award three more contracts - two for networks and one for the Sewage Treatment Plant.
