Description
The Klargester 7,150 litre shallow dig septic tank is a high-capacity wastewater treatment solution for domestic installations where standard excavation depth is not achievable. It is commonly specified for large dwellings, replacement installations, and rural properties where site constraints such as high water tables or restricted dig depth apply.
With substantially increased capacity compared to smaller shallow dig models, the 7,150 litre unit is suited to properties with significant foul water demand while maintaining the benefits of reduced excavation depth. The shallow dig design helps to minimise groundworks time and site disruption, supporting efficient installation without compromising long-term performance.
Manufactured by Klargester, this septic tank is engineered for durability and consistent operation when installed in accordance with UK regulations, making it a trusted choice for contractors and installers working on private drainage schemes.
