Saudi Arabia’s National Water Company (NWC) has tendered a contract for the construction of 10 sewage treatment plants as part of the next phase of its long-term operations and maintenance (LTOM) sewage treatment programme.

According to the original scope, the Eastern A Cluster (LTOM14) package will have a total treatment capacity of 184,440 cubic metres a day (cm/d) at an estimated cost of $180m.

The bid submission deadline is 30 September.

The tender follows recent contract awards for North Western A Cluster Sewage Treatment Plants Package 11 (LTOM11) and the Northern Cluster Sewage Treatment Plants Package 10 (LTOM10).

MEED exclusively reported that a consortium comprising China’s Jiangsu United Water Technology, the UAE’s Prosus Energy and Saudi Arabia’s Armada Holding had been appointed as a contractor for each of these projects.

Package 11 will have a combined capacity of about 440,000 cm/d at an estimated cost of about SR211m ($56.3m).

Package 12 will have a combined treatment capacity of 337,800 cm/d at an estimated cost of about SR203m ($54.1m).

In April, NWC also opened finanical bids for North Western B Cluster (LTOM12) of its sewage treatment programme.

The contract covers the construction and upgrade of seven sewage treatment plants with a combined capacity of about 162,000 cm/d.

MEED previously reported that the following companies had submitted proposals:

• Alkhorayef Water & Power Technologies (Saudi Arabia)
• Civil Works Company (Saudi Arabia)
• Miahona (Saudi Arabia)
• Beijing Enterprises Water Group – BEWG (Hong Kong)
• Al-Yamama (Saudi Arabia)

These bids are currently under evaluaton, with an award expected in the coming weeks, a source said.

The tender for the North Western C Cluster (LTOM13) project had been put on hold, although it is understood that this is now likely to be the next package to be tendered.

Under the original scope, this package covers the construction of 10 sewage treatment plants.

In total, the LTOM programme comprises 19 packages split into two phases. This contract for LTOM10 was the first to be awarded under the second phase of NWC’s rehabilitation of sewage treatment plants programme.

As MEED understands, there have been several discussions in recent months regarding changes in scope details and potential expansions. This involves potentially grouping some upcoming projects.

NWC previously awarded $2.5bn-worth of contracts in the first phase. This comprises nine packages covering the treatment of 4.6 million cm/d of sewage water for the next 15 years. Phase two of the programme includes 10 packages covering 117 treatment plants.
