LONDON ,UK, MAY 16, 2019 -- Water utilities have a major challenge working with local food businesses to prevent fats, oils and grease entering the sewer network, but a combined data and marketing approach could be the answer, says Michael O'Dwyer, founder and chief executive, SwiftComply.
Fats oils and grease (FOG) in the sewer network are a £90 million a year headache for water utilities in England and Wales. While giant fatbergs get all the press coverage, there are hundreds and thousands of smaller blockages that the water companies are tasked with clearing day-in day-out.
Growing urban populations and denser concentrations of food outlets, along with legacy sewer networks, are all contributing to FOG build-up in the network. And while larger food production facilities have to comply with environmental trade effluent regulations, unlike in the US and Ireland, no such rules exist for the 500,000 food service establishments (FSEs) in the UK.
In an ideal world, the problem would be solved if every FSE installed a grease-trap. Correctly-sized, well-maintained equipment is the first step to prevention. Capturing FOG at source and at scale would also provide the opportunity to generate significant biofuel resources, providing a stimulus to circular economy initiatives.
SwiftComply is working closely with UK utilities in combined digital and face-to-face education and engagement programs. One of the aims is to collate data to better understand the food businesses using the sewerage networks.
Yorkshire Water has partnered with SwiftComply, and with support from City of York Council, to deliver a food service engagement pilot in the York city area to tackle an increase in issues relating to FOG and fatbergs. SwiftComply will engage both digitally and physically with around 1,000 food businesses to assess and improve their onsite FOG management practices.
The project campaign will involve SwiftComply establishing and publishing a website and digital media campaign to engage with food businesses. Further to this, food businesses will be provided with the opportunity to opt into an onsite FOG Risk Audit, carried out by the SwiftComply team. Food businesses will be provided with a report detailing areas they can improve and reduce their FOG Risk, along with support to manage these changes.
Initially, above-ground data on the number of restaurants, their GPS coordinates, cuisine-type and contact details are collected using specially designed cloud-based software. This information can then be expanded by finding out more about onsite FOG management from site visits, telephone interviews and digital questionnaires.
The questions being asked include – Is a grease-trap installed? Is it correctly-sized and fit-for-purpose? How is it maintained? Where is the captured grease disposed to?
The data builds up a valuable resource for the utilities to tap into, facilitating much more robust decision-making around effective FOG education programs with local business owners. The FSEs are also provided with digital and paper educational materials promoting best practice kitchen grease management.
This includes washing-up practices such as advice on the dry-wiping of greasy cookware, crockery and equipment; along with guidance on safe storage of waste oil. The rule of thumb being to remove as much oily waste as possible before it comes into contact with water.
