GEORGETOWN, Guyana – August 17, 2026 – Bangladesh-headquartered engineering contractor Sigma Engineers Ltd Inc. has announced it will pursue formal legal action against Guyana’s Opposition Leader Azruddin Mohamed over damaging public claims related to the award of some GY$12 billion in state contracts issued by Guyana Water Incorporated (GWI), the firm confirmed in an official statement released Monday.
In the statement, the company issued a full categorical rejection of the claims brought by Mohamed, describing the opposition leader’s assertions as serious misrepresentations of key facts. Having already retained specialized legal counsel to address the matter, Sigma Engineers is moving forward with all appropriate legal remedies to address the false statements, per the company’s announcement.
“Further updates on both our operational activities and the specific allegations raised will be released at a proper juncture, as our legal team continues to review the details of this case,” the company added.
Mohamed made the allegations in a 12-minute audio-visual address posted to Facebook earlier on Monday, in which he also named Mohamed Aqtar Ali – the brother of sitting Guyanese President Irfaan Ali – in connection to the contracts. As of Monday afternoon, neither the state-owned water utility GWI nor President Ali had issued a public response to the opposition leader’s claims.
To correct what it calls widespread misinformation about its origins and contracting history in Guyana, Sigma Engineers explicitly denied the false claim that the firm was incorporated just five days before being awarded a government contract. The company clarified that its parent entity was originally established and has operated continuously in Bangladesh since 2003, and it completed formal registration to do business in Guyana on October 6, 2022. Its first contract in the country was awarded following a full competitive public bidding process overseen by Guyana’s National Procurement and Tender Administration Board (NPTAB) in 2026, the firm confirmed.
Sigma’s track record of water infrastructure projects in Guyana dates back more than three years: In August 2023, GWI first selected the Bangladesh-based firm as the lead contractor for a new water treatment plant serving communities from Soesdyke to Craig along Guyana’s East Bank Demerara. A year and a half later, in March 2024, GWI awarded Sigma additional contracts to deliver two more water treatment plants in Cummings Lodge and Caledonia. By October 2025, the new Cummings Lodge facility – constructed by Sigma at a total cost of GY$1.3 billion, with a large workforce of local Guyanese staff – was completed.
Addressing the naming of Mohamed Aqtar Ali, the President’s brother, Sigma Engineers confirmed that Ali has been contracted to the firm’s Guyana operations as a senior technical consultant. The company stressed that Ali holds no ownership or formal affiliation with its parent Bangladesh-based entity.
Sigma Engineers emphasized in its statement that it remains fully committed to operating in full compliance with all Guyanese laws and regulatory requirements, while upholding the highest standards of professional conduct, accountability, and integrity across all its projects. “We respect the principle of due process, and we believe all public discussion regarding companies operating in Guyana must be rooted in accurate, verifiable information,” the statement concluded.
