MTS vs. fat, oils and grease

Fat, oils and grease in drains and sewers mix and congeal to cause blockages which can lead to flooding.

Known as FOG, these fats accumulate with other debris to create solid blockages which can rapidly overload sewer networks. Where sewers also carry rainwater, or storm overflows run into sewers, an overloaded system can cause unnecessary discharge of sewage into streams and rivers. Where there are no overflows sewage can flood into homes, businesses, parks and gardens.

Blockages account for 80% of sewer flooding incidents and UK water and sewerage companies deal with around 366,000 sewer blockages every year.

Even if a sewer does not flood, FOG in the system can affect sewage pumping stations. An MTS crew recently worked to clear a Warwickshire pumping station of fat for our customer Severn Trent Water.

Watch our team in action here, working under confined space conditions, to clear the FOG contamination from the pumping station. Aaron McCusker, Senior Network Technician for Severn Trent Water explains how to avoid putting fat, oils and grease into the system.
