Zero Dust Limit Breaches in 2025: A Major Environmental Milestone at Havant Thicket Reservoir

27 November 2025

Future Focused Construction, Powered by Partnership

Future Water is proud to announce that throughout the 2025 earthworks season, no breaches of dust limits were recorded at Portsmouth Water’s Havant Thicket Reservoir project. Dust levels remained well below the recommended construction threshold of 45 µg/m³ for PM10, demonstrating our commitment to environmental excellence and community wellbeing.

Continuous Monitoring and Transparency

From March to October, our Future Water Environment Team carried out continuous 24/7 on-site dust monitoring at three agreed fixed human-receptor locations. This was complemented by daily off-site checks using Environment Agency–approved handheld equipment. Both the fixed and handheld monitors provided live data, ensuring full transparency and enabling us to share results openly with local authorities on a weekly basis.

Maintaining Standards During a Dry Summer

Despite a particularly dry summer, our team maintained exceptional standards through:

  • Daily on-site dust inspections
  • Strict site speed limits
  • Effective dust management across the site

Going beyond compliance is part of how we work. Every day, our vehicles use collected rainwater from the reservoir site to dampen haul roads and working areas — a simple, sustainable step that helps protect air quality even during the hottest, driest weather.

We also carried out targeted monitoring close to nearby properties, reassuring residents that dust is effectively managed.

A word from our Environmental Manager –

Maintaining air quality isn’t just about meeting compliance, it’s about protecting our workforce, our neighbours, and the environment. Achieving zero dust limit breaches this season reflects the commitment of everyone on site.”

Terry Bellingham, Future Water Environmental Manager for Havant Thicket Reservoir
