For over 33 years, Browne has proudly served as the framework provider for Thames Water's reservoir maintenance, supporting the vast network of reservoirs that supply water to millions of Londoners and into the Thames Valley. In 2025, Browne undertook some of its most ambitious projects yet, with major works completed simultaneously at two of London’s largest water treatment works—Coppermills WTW and Hampton WTW. Combined, these two sites provide over half of London’s water supply, making their efficient operation essential for the city.
Browne’s skilled workforce, with more than 50 operatives working across both sites, played a key role in delivering these projects on time. Coppermills WTW, in particular, saw crews working seven days a week to meet deadlines, underscoring Browne’s commitment to maintaining London’s water infrastructure. Despite the significant manpower needs of these projects, Browne continued to service the rest of its Thames Water, Southern Water, and South East Water reservoir maintenance commitments without disruption, demonstrating the company’s operational strength and resource management.
As the demand for high-quality maintenance work on water assets grows, Browne remains a key partner to Thames Water, ensuring the reliability and safety of London’s water supply.
