Water Management, Optimisation and Reuse

Welcome to our page dedicated to water management, reuse and optimisation! As the world's population continues to grow and climate change impacts our natural resources, it's more important than ever to prioritise the responsible and sustainable use of water. By implementing strategies to minimise waste, conserve resources and maximise efficiency, we can help ensure a more resilient and sustainable future for all. On this page, you'll find information on how we can work together to protect our planet's most precious resource!

Comprehensive Water Audits

A water audit can help you:

  • Reduce your water consumption
  • Optimise your water usage
  • Save you money
  • Improve your environmental sustainability
  • Meet regulatory requirements
  • Improve your reputation with customers and stakeholders

Overall, a water audit is an essential tool for any organisation looking to reduce costs, improve sustainability, and enhance their reputation. Contact us today to learn more about how a water audit can benefit your business.

Energy Recovery

Although wastewater treatment requires a lot of energy, it is a major source of clean energy. For instance, some treatment phases release methane, which can be captured and recycled to produce heat and electricity. On the other hand, treatment sludge can make for an excellent source of fertiliser. By harnessing these different clean energy sources, EPAS International can turn a necessary process into a source of energy.

Our expertise:

  • Anaerobic water treatment expertise
  • Feasibility studies for bio-gas production and reuse
  • Design of anaerobic treatment units
