TikTok 'Blue Lagoon' Owners Warn Swimmers

Owners of Brombil Reservoir, a site that went viral on TikTok, have warned the public against entering, particularly during the current hot weather. The reservoir, known for its striking turquoise color, attracted thousands of visitors, leading to traffic and littering problems. Leisure Estate Investments Ltd, which acquired the site in 2024 for £20,000, has introduced a £2 entry fee as a temporary measure to deter unauthorized visits and manage the site.

The company is concerned about safety risks associated with swimming, paddleboarding, and damage to structures. Despite access via public footpaths, barriers installed on the dam face were removed by trespassers. The £2 levy aims to fund clean-up operations and manage unauthorized access due to "inherent safety risks." The reservoir, a repurposed 19th Century colliery, plays a vital role in flood protection and supports a unique aquatic ecosystem now facing severe environmental degradation.

Nearby residents have reported suffering from traffic and litter issues following the reservoir's viral fame. Brombil Reservoir Ltd has invested in structural surveys and waste clearance since taking ownership. However, escalating compliance costs from Natural Resources Wales (NRW) for high-risk dams require significant ongoing investment. The company has repeatedly sought support from Neath Port Talbot council and local politicians without success.

Owners warn that without public sector support, they may be forced to decommission the reservoir, which would eliminate flood defenses and destroy a vital ecological habitat. Neath Port Talbot council stated that as the site is privately owned, decisions rest with the owner, though they remain open to dialogue. The council has offered advice where appropriate but stressed that any future arrangements must ensure responsible visitor management.
