Pizza Hut – GRU Auto® Automatic grease trap was installed at Pizza Hut in 2020. The drainage around the site had been experiencing blockages. Severn Trent Water approached Clearflow to install a system that would prevent further blockages. Pizza Hut decided on the G.R.U Auto Automatic grease trap due to the ongoing costs of emptying a passive grease trap. Plus the fats, oils & grease the G.R.U Auto recovered can be recycled and sold back to their oil suppliers.
