Client requirements

In Spring 2017 40Seven were appointed by Thames Water to carry out a large river survey as part of a joint initiative between Thames Water Utilities and Environment Agency. The survey included 14 rivers, totalling approximately 630 km in length, all located within the M25 with the aim of better understanding the water quality within these rivers.


40Seven Solution

The aim of the river walk surveys was to confirm and plot the presence of any chartered or unchartered outfalls discharging in to the specified length of river. The surveys also identified any visual presence of pollution into the watercourse and included the capture of supporting information to determine the source and pathway where possible.


The Results

40Seven collected all field based data using the ‘ArcGIS Collector’ application on tablet platform IOS. The information collected included geo referenced data, high resolution photographs, outfall proformas and written descriptions of any pollution locations. The final report including plans of the watercourse and identified outfalls and pollution locations was produced through an automated report function within the Data Collection Application. The report detailed all known information about pollution sources and included photographic evidence of the identified outfalls and pollution as well as of the surrounding area.
