Rainwater harvesting systems – TWINBLOC well extension

This is an indispensable element of a rainwater management system, allowing for optimal adjustment of the well height to the excavation depth during the installation of the TWINBLOC tank. The well extension is dedicated to TWINBLOC tanks and provides convenient access to installation elements, as well as ensuring a safe and aesthetic appearance of the entire system.

Construction and application

The well extension is made of a durable material, which guarantees its long-term operation even in difficult ground conditions. Its main task is to increase the height of the inspection chamber, which is particularly useful in the case of deeper tank placement. Installation of the extension is simple and intuitive – just put it on the existing well and fasten it with screws (not included). This allows installers to easily adapt the system to specific site conditions.
