If you’re tired of frequent cesspit emptying, unpleasant smells, or concerns about environmental compliance, it might be time to upgrade to a sewage treatment plant. At Proseptic, we specialise in replacing outdated cesspits with modern, efficient systems that meet UK regulations.

Why Replace Your Cesspit?

Cesspits are:

  • Outdated – They don’t treat waste, just store it.
  • High maintenance – Regular emptying is costly and inconvenient.
  • Risky – Overflow or leakage can lead to fines and environmental damage.

Upgrading to a sewage treatment plant means:

  • Better environmental outcomes.
  • Cleaner, treated effluent.
  • Fewer maintenance costs.
  • Long-term legal compliance.

How the Replacement Process Works

1. Site Survey

We assess your current system, drainage layout, ground conditions, and access.

2. Regulatory Checks

We manage planning permission (if required) and Environment Agency permits for discharge.

3. Safe Decommissioning

Your old cesspit is safely emptied, cleaned, and either removed or backfilled.

4. System Installation

We install a compliant sewage treatment plant with full groundworks, soakaway/drainage field (if required), and electrical connections.

5. Testing & Handover

We test the system, show you how it works, and provide servicing guidance.

Benefits of a Sewage Treatment Plant

  • Better for the environment and property value
  • Compliant with 2020 General Binding Rules
