UKDN Waterflow create new grading system to reduce drainage pollution

Posted: Monday 25th March 2019

UK drainage and wastewater management company – UKDN Waterflow (LG) Ltd – have created a new grading system which aims to give non-industry professionals and homeowners the ability to grade their drainage system and understand when professional help may be required, as well as identify when their drainage system may be breaking the law.

There is still an estimated 150,000 to 500,000 UK homes with some sort of drain misconnection. In aid of reducing drain pollution and improving drain performance, UKDN have created the Optimum Performance Code which provides an easy to read and understandable coding system for non-industry professionals.

The current CCTV survey grading system - provided via the Water Research Council (WRC) or smart sewage inspection software from WinCan or Innovyze - illustrates the condition of any given drain on a scale of 0 to 5, with 0 being the best and 5 being the worst. It is a suitable coding system but is often considered too technical for domestic users and non-industry professionals.

The Optimum Performance Code aims to position the drain grading system alongside the widely recognised EU Energy Efficiency Directive for common household appliances. This way, it brings complete clarity to drain inspections at all levels, whether it concerns household foul sewers, surface water sewers or industrial-size sewers. The Optimum Performance Code is split into five distinct grades for judging the condition of a drain and sewer.Clear descriptions without the jargon make it easy to evaluate when professional action needs to be taken for proper drain maintenance, such as drain unblocking services, CCTV drain surveys or drain cleaning – which means that illegal scenarios that present risks to tenants and neighbours, for instance, can be prevented.
