Introduction to DTS

DTS = Distributed Temperature Sensing

Measuring temperature along a fibre-optic cable in a sewer pipe

Method to identify inflows in sewer pipes


22 June 2012

Why DTS

Very rich and visual data, allowing targeted response

Unprecedented type of information from sewer system

Significant detail in both time and space – not a snapshot

Low level of interference and cost effective

Intelligent identification of problem within sewer system

Successful where many other approaches have failed

wastewater entering a storm water system

flow direction

Applications: storm sewers


22 June 2012

Application: foul sewers

STORM EVENT

STORM WATER INFLOWS

WASTEWATER INFLOW

FLOW DIRECTION


22 June 2012

Large inflow (creek)

Applications: foul sewers


22 June 2012

DTS projects

Netherlands: 15+ projects for municipalities (Eindhoven, Den Haag, Breda,

Almere, etc.) on-going research projects

Germany: 2 projects for Water Utilities (Wuppertal, Emmerich) 1 research project (initiative)

Denmark: 1 project / research for municipality (Aarhus)

UK: 1 pilot project for Water Utility (Anglian Water)


22 June 2012

Typical reasons for using DTS Illicit connection or inflows to storm/foul sewers systems

capacity improvement -> sewer: reduce CSOs

-> WwTP: prevent expansion

flooding of sewers or pumping stations

reduction in energy consumption, pump wear, dosing chemicals (sewer, WwTP)

reduction in pollutant load via WwTP effluent


22 June 2012

Particular UK issues

Transfer of private sewers regulation 2011

Achievement of Environmental discharge consents

Operational efficiency

Looking towards AMP 6

22 June 2012

Trial Site – Little Wakering (Southend)

Suffers from frequent flooding Local pumping station exceeding

capacity Previous attempt to identify inflows

inconclusive


22 June 2012

Trial Site – Little Wakering

Deployment of DTS in partnership with Kwakernaak (Dutch) and Barhale contractors

2 monitoring cables deployed (650m & 950m)

Sewer monitored for 4 weeks Initial results have identified a number of

storm water inflows
