The first, a circular tank of almost 36m in diameter and a height of 4.3m, was built using 94 pre-cast concrete panels as a pre-treatment tank for agri-based feedstock.

The second rectangular tank – 63m in length and 8.4m wide with a height of 4.3m – was made up of 136 pre-cast concrete panels and put into operation as the main treatment tank.

Each of Whites Concrete’s Sealwall units are jointed using a tried and tested compressible hydrophilic jointing method.

Steel fixings hold the precast units together, making a visibly robust system.

The wall units are factory-cast to very high quality standards, and designed to the exacting requirements of the Water Retaining Concrete Code of Practice BS8007, and Eurocode EC 1992.
