Chinese firm wins Oman sewage network contract

9 February 2026

 

China’s Hunan Installation Overseas Engineering has won an engineering, procurement and construction (EPC) contract to build water supply and sewage networks in the Al-Khuwair 17-1 municipal planning zone in Muscat, Oman.

The contract awarded by state utility Nama Water Services (NWS) covers the construction of water supply, drainage and treated effluent (TE) systems.

The scope of work includes the supply and installation of about 30 kilometres of sewage pipelines and 15km of water supply pipelines. 

Hunan Installation has been expanding in Oman recently through contracts with NWS.

According to MEED Projects, the contractor was awarded a $37m EPC contract last March to build water distribution networks and housing connections in Khasab, Musandam Governorate.

In 2024, it won a $70m contract from NWS for a major water distribution scheme in the wilayats of Samail and Izki. The project includes reservoirs, pumping stations and more than 400km of pipelines.

Unlike its previous NWS contracts, which focused on the distribution of potable water, Hunan Installation’s job for the Al-Khuwair scheme covers water supply along with sewage and drainage networks.

Hunan Installation recently submitted a bid for another NWS tender covering the construction of a $60m water distribution network in A’Seeb, Muscat, under Package 3 (Phase 2).

The $60m project has attracted seven commercial bids:

  • Towell Infrastructure Projects (Oman): $52.08m
  • Target (Oman): $55.12m
  • Hunan Industrial Installation (China): $56.96m
  • Societe Egyptienne d’Entreprises (Egypt): $58.30m
  • Hassan Allam Construction (Egypt): $59.61m
  • United Gulf Construction Company (Oman): $73.27m
  • Petrojet & Partners (Egypt): $863.70m

NWS is also procuring for the construction of an $80m water transmission system project, which has attracted seven bids, with the lowest bid from local contractor Eastern Overseas ($52.94m).

Contracts for both projects are expected to be awarded in this quarter.
