Onn Point were appointed to assist a private client as they wanted to upgrade an existing septic tank to a treatment plant. The outdated septic tank was successfully replaced with a modern treatment plant that met the latest environmental standards. This upgrade, using the help of soakaway design calculations, not only improved effluent quality but also ensured compliance with regulations.
Full scale infiltration tests were carried out in line with BS6297 confirming ground conditions were suitable for the use of infiltration. A sustainable drainage strategy diverting the existing system to a treatment plant was produced, allowing treated effluent to discharge to a foul field drain.
