Common Questions on Installation and Maintenance

Find clear answers about our installation procedures, ongoing maintenance, and compliance requirements to help you make informed decisions about your sewage and drainage systems.

  • What does the sewage treatment plant installation involve?

    Our installation process includes site assessment, system design tailored to your property, excavation, tank placement, pipework connection, and thorough testing to ensure full compliance with UK environmental and Building Control standards.

  • How often should I schedule maintenance for my system?

    Regular maintenance is essential to keep your system functioning efficiently. We recommend annual inspections and servicing, including sludge removal and system checks, to prevent blockages and extend the lifespan of your equipment.

  • Are your installations compliant with current regulations?

    Yes, all our installations meet the latest UK environmental legislation and Building Regulations Part H. We ensure systems are designed and installed to satisfy local authority requirements and environmental agency standards.

  • What should I expect during cesspit replacement?

    We safely remove the existing cesspit, dispose of waste through licensed carriers, and install a new, regulation-compliant tank. We also advise on upgrading options if a more efficient system suits your property better.

  • Can you handle drainage repairs and CCTV surveys?

    Our team conducts detailed CCTV surveys to diagnose drainage issues accurately. We provide targeted repairs such as pipe replacement, joint repairs, and chamber refurbishments to restore system integrity and prevent future problems.
