Cockermouth Extra Care Home - Rainwater Harvesting

Another precast concrete tank supplied by Ecozi has been installed in record time at a new 68 room care home under construction by G&J Seddon at Cockermouth. The 23,000L tank was HIAB’d into final position by the delivery truck. Using these tanks eliminates extra craneage cost and the tank requires no concrete base or backfill. Compared to a GRP tank alternative the saving in installation cost is approximately £3,500. It took just 80 minutes from when the delivery truck pulled up to placement in the final position. More information about this project.

Roger McEvoy, Director at Ecozi said:

“Ecozi always uses precast tanks for commercial projects. They allow Ecozi to offer the best-in-class rainwater harvesting solutions, similar to the advanced German market where concrete tanks are common place. Ecozi rainwater harvesting systems utilising precast tanks and factory built control appliances require a full system evaluation to appreciate the cost savings Ecozi bring to a project. Savings compared to traditional systems amount to several thousand pounds by eliminating a concrete base and backfill, craneage, civils design and time to install. Ecozi control appliances require only piping hook-ups at first fix and are usually shipped later in the project cycle.”

Retrofit rainwater harvesting system at the Office for National Statistics in Newport

Ecozi has completed the supply and installation of a retrofit rainwater harvesting system at the ONS (Office for National Statistics) in Newport. The system comprises of two HyproDuo factory built, hybrid control appliances.
