We install reliable sewage treatment systems for homes and businesses across Cornwall. These units treat wastewater so it can be safely discharged, making them ideal for properties without mains drainage.

Choosing the right system depends on factors such as property size, water usage, soil conditions, local regulations, and the level of treatment needed.

We assess these requirements in full and recommend the most suitable domestic or commercial sewage treatment plant, installed in line with current regulations.

How do Sewage Treatment Plants Work?

A treatment unit separates solids, uses aeration to support bacteria that break down waste, and produces cleaned effluent for safe discharge. Most systems use a small amount of electricity to power internal components.

  1. Wastewater enters the primary chamber where solids settle.
  2. The liquid moves into a biozone, where air is circulated to encourage natural biological treatment.
  3. The final chamber holds water that is typically around 95% clean and ready for safe discharge into a drainage field or, where appropriate, into nearby watercourses.

Our Installation Process

Assessment: We review your property, usage levels and site conditions to identify the most effective system.

Percolation Testing: Before installing drainage fields, we test how well the soil absorbs water.

Excavation & Installation: Our experienced team handles all groundworks and installs the system in full compliance with regulations.

Drainage Fields: These allow treated water to filter through the soil, removing any remaining contaminants naturally.

Benefits of Modern Treatment Units

  • Environmentally friendly: Clean, filtered water can be safely discharged into drainage fields, rivers, streams, and other bodies of water if approved by the local environment agency.
  • Efficient & affordable: Many systems are energy-efficient and require minimal electricity to effectively breaking down waste.
  • Long lasting: With proper maintenance, most sewage treatment plants can last up to 20 years or more.
  • Off-grid: A reliable solution for sites with no mains drainage connection.
