Wastewater monitoring to study the temporal and spatial representativeness of flow and pollution discharge measurements

Résumé

Measuring flow-rate and pollutant discharges through sewer networks is required for legal, technical and management reasons. This paper presents an experimental study combining continuous monitoring of flow and water quality parameters with studies of the velocity and suspended solids spatial distribution in order to understand both the question of temporal and spatial representativeness of continuous measurements. The experimental site has been chosen to investigate the situation in both a uniform and a complex situations, it is formed by the junction of two channels. Three measurement points were selected: upstream, downstream and at the junction. Firstly, the context of this project is reported, secondly the experimental investigations and data validation procedure are detailed and finally the results are presented and discussed. Logical and statistical automated methods were used to validate data. The necessity of the application of data validation procedure was proved for faulty data detection and faulty data correction. The ranges of quantity (heights, velocities and so flow rates) parameters were determined using continuous monitoring. Some trend evolutions and ranges were noted for temperature, conductivity, pH.
