Rubicon Water’s latest ASX announcement, dated 28 September 2026, covers the selection of a joint venture bid incorporating its technology for an irrigation modernisation project in Morocco’s Tadla region.

About Rubicon Water

Rubicon Water Limited is an Australian water technology solutions company. Its Total Channel Control (TCC) technology, automated canal regulation gates and NeuroFlo software platform are designed to monitor and control canal flows and water levels in real time.

Selection for the Tadla project

According to the announcement, the Office Régional de Mise en Valeur Agricole du Tadla (ORMVAT), a Moroccan Government agency, announced through Morocco’s public procurement portal that a joint venture bid had been selected as contractor for an irrigation modernisation project. The bid was submitted by a joint venture between Rubicon’s Spanish and Moroccan partners and includes approximately A$12 million of Rubicon solutions. The portal announcement was made on 25 September 2026.

The selection followed separate administrative, technical and financial assessments. Under Moroccan tender law there is a statutory 15-day appeal period, after which the project is expected to proceed to formal contract execution.

Scope and contract terms

The project will modernise regulation and operation of the main canals serving the Béni Moussa irrigation perimeter, which covers approximately 69,600 hectares. About 27,000 hectares within the perimeter have been or are being converted from gravity irrigation to pressurised drip irrigation. The existing regulation infrastructure has been operating since the 1950s.

Rubicon’s scope includes TCC technology, automated canal regulation gates, communications infrastructure and the NeuroFlo platform, supplied through a contracting arrangement with its Spanish and Moroccan partners. The contract will be denominated in euros and includes secure payment terms. If executed, it would be Rubicon’s largest contract in the EMEA region and its second-largest single contract outside Australia.

Pipeline context

Rubicon said Tadla is one of five major incremental opportunities totalling A$47 million categorised as ‘Trade’ in its FY26 results presentation, alongside the Canalone contract awarded in late August. The company said it continues to progress towards securing these and other opportunities.

Sector context

Irrigation modernisation projects in agricultural regions often involve government agencies, public tenders and multi-party contracting structures. Selection through a procurement portal is typically followed by a formal appeal window and contract execution before work begins.

Water-management technology is generally evaluated on its ability to deliver stable, accurate water delivery across canal networks, particularly where farms are moving to pressurised drip systems.

Risks and uncertainties

The selection is not yet a signed contract. The appeal period must pass, and Rubicon’s contract depends on the joint venture being contracted and the project being commissioned. Contracts of this kind can be subject to delays, changes in scope or tender challenges.

Rubicon’s contract is euro-denominated and delivered through partners, which introduces currency and counterparty considerations. The A$47 million of ‘Trade’ opportunities mentioned by the company are opportunities rather than secured contracts.

What's next

The next step described in the announcement is the end of the 15-day appeal period, followed by formal contract execution if no challenge arises. Rubicon said it is already working on further opportunities across the region and continues to progress the other major opportunities classed as ‘Trade’.
