Phosphorus Control for Public Water Bodies

 Evidence-based tools for councils managing lakes, ponds, and reservoirs

Nutrient Pollution Puts Pressure on Our Water Systems


Local authorities play a critical role in managing the health and accessibility of our lakes, ponds, and reservoirs. But nutrient enrichment—especially from phosphorus—continues to challenge public water bodies across the UK.


Left unaddressed, this can lead to:

  • Harmful algal blooms
  • Reduced water quality
  • Ecological imbalance
  • Public dissatisfaction and rising maintenance costs



We believe in working with councils to protect water resources that serve both people and nature.

A Proven, Regulator-Approved Tool for Phosphorus Management


Phoslock is a scientifically developed product that binds phosphorus in the water and sediment.
It’s approved by the Environment Agency (EA) and Natural England, and has been used in over 700 water bodies across the UK and internationally.



Applications include:

  • SSSIs and AONBs
  • Urban and recreational lakes
  • Event-standard open water venues (Olympics 2022, Commonwealth Games 2014)


Key benefits:

  • Long-term phosphorus binding
  • Minimal disruption during application
  • No impact on public access or wildlife
  • Aligns with existing lake and catchment management plans
