The Clearwater 59,000 Litre Septic Tank is a high-capacity underground wastewater treatment solution designed for residential developments, commercial properties, agricultural sites, holiday parks, and other applications requiring reliable off-mains drainage. With an impressive 59,000 litre (59m³) capacity, this septic tank provides efficient primary sewage treatment for properties generating high volumes of wastewater.

 

Designed in accordance with the installation requirements and discharge standards of BS 6297:1983, the Clearwater 59,000L Septic Tank offers dependable long-term performance and effective wastewater management. Its substantial capacity allows wastewater to be retained for sufficient time, enabling solids to settle naturally and supporting the treatment process before effluent is discharged to a suitable drainage field.

 

The septic tank operates using a proven single-chamber treatment system. Wastewater enters the tank, where heavier solids settle to the bottom and form sludge. Naturally occurring anaerobic bacteria begin breaking down organic matter, while the clarified liquid effluent flows through the outlet pipe and into a drainage field for further treatment. This simple but effective process makes septic tanks a trusted solution for properties that are not connected to the mains sewer network.

 

Suitable for domestic, commercial, agricultural, and industrial applications, the Clearwater 59,000 Litre Septic Tank provides a practical and cost-effective wastewater treatment solution. When siting the tank, it should normally be located at least 7 metres from any dwelling and, wherever possible, a minimum of 10 metres from nearby watercourses. Adequate access should also be provided for tanker emptying and routine maintenance.
