Comprehensive Solutions and Expert Workmanship

  • Survey & Diagnostics of Existing Systems

    Sewage treatment systems and soakaways deteriorate over time. All plant and materials have a lifespan and soakways become clogged.

    If left unchecked, a minor fault can deteriorate quickly, leading to irreparable damage and serious pollution. As a system owner, it is your legal responsibility to prevent pollution.

    If you are in any doubt that your system is operating correctly act quickly.

    We offer a free visit and initial diagnostic survey.

  • Design & Installation of
    new systems

    Whether you are developing a new site or replacing an old system, we will ensure you get the most efficient and cost-effective solutions for your drainage needs.

    Off-grid sewage treatment systems must comply with a range of design standards and legal requirements, and we will deal with it all from start to finish.

    We will hand over a fully compliant system at the best possible price.

  • Licensing, permits
    & registration

    SEPA requires that all sewage treatment systems in Scotland meet strict standards and be registered. In some cases this is extended to a full licence to discharge.

    We will make sure that your system is correctly designed, registered and/or licenced to meet your legal obligations and help you comply with your ongoing responsibilities to manage and maintain your system.
