Dead animals found in Brentford canal linked to sewage

Dead animals have been discovered washing up in the Brentford Lock basin, a stretch of canal in West London, prompting concerns among residents about the water quality. The issue is believed to be exacerbated by plumbing misconnections, which are reportedly sending untreated sewage into local waterways. This problem has been highlighted by residents at a meeting of the Brentford and Syon Area Forum.

Sewage and Health Concerns

Paul Keane informed local councillors on Monday, September 21, that the problem is worsened by the summer heat. He stated that dead aquatic animals, primarily found in the Brentford Lock basin where the Grand Union Canal flows before meeting the River Thames, showed signs of E. coli and botulism. Mr Keane explained that botulism toxins thrive in warm, shallow water, a condition created by stagnant conditions that also accelerate E. coli growth. He noted that the water has to be hygienic, especially for water sports activities, and that there are times when it is not.

Mr Keane clarified that he did not believe Hounslow Council was at fault but stressed the need for a comprehensive strategy to address the issue if the canal is to be used more, particularly by children. He described the situation as a 'very difficult issue' that requires an 'overall strategy'.

Cross-Borough Collaboration

Councillor Katherine Dunne acknowledged that work is being done across boroughs to tackle the problem. She mentioned a River Brent catchment area group and confirmed that officers in Ealing and Brent councils are investigating misconnections. Councillor Dunne stated that while the issue originates in those boroughs, it affects Hounslow. The Canal and River Trust reportedly conducts water tests before water sports events and has found the water to be 'generally quite clean'.

Next Steps for Residents

The Committee Chair, Councillor Dan Bowring, thanked Mr Keane for raising the matter, noting that the affected sites are within the Brentford West ward. He advised residents to contact their local ward councillors, adding that all councillors in Brentford and residents would be concerned about this situation.
