HS2 flow monitoring project with NHTB

Flood and pollution prevention experts, Detectronic, are partnering with Hertfordshire-based civil engineers, NHTB Consultancy, to deliver a flow monitoring survey for Thames Water in a number of sewers on the proposed HS2 line around Euston in London.

As part of the comprehensive planning for HS2, Thames Water needs to understand exactly what is happening in the sewer network in and around the areas the proposed route will take.

Explains Tom Butler, director at NHTB Consultancy: “Where the sewer network comes directly into contact with the HS2 route, Thames Water may have to move or divert sewer pipes. By implementing a flow monitoring survey, we will be able to provide them with a complete picture of how the sewer is affected by rainfall events that will then determine which pipes will need to be replaced and diverted.

“We’ve worked with Detectronic on a variety of similar projects for the last five years so they were our first choice to supply monitors and rain gauges and analyse the data over the course of the survey.”

Continues Dave Walker, commercial director at Detectronic: “We have supplied Tom with eleven MFSM flow monitors which his team will install in strategic locations within the sewer network along with three rain gauges that will be located above ground.

“Each of these monitors will transmit real-time flow data to our data centre every two minutes over the course of the survey. Following continued processing and analysis, our data analysts will be able to provide a highly accurate and detailed report of how the sewer network performs under heavy rainfall conditions that will then enable Thames Water to fully comprehend what is happening in a specific sewer pipe at any given time.”

Concludes Dave: “Every project we’ve worked on with NHTB has proven invaluable for the client in question. The report from this survey will undoubtedly provide Thames Water with an unrivalled level of detail which will help them to successfully complete any required diversion work both efficiently and cost-effectively.”
