Stormwater&Sewers seminar at World Water Day 22 March

Published: 25 March 2022

On World Water Day 2022, which had as its theme "Groundwater: making the invisible visible", it was the start-up of Stormwater&Sewers new seminar series within the themes Sewers and Resource Efficient Small Sanitation Systems.

About 40 participants listened to Annelie Hedström and Inga Herrmann when they told about how groundwater, wastewater and LPS systems are connected. They presented some results from the compilation of knowledge about experiences of LPS systems that showed difficulties in dimensioning these systems. Results from a recent study on wastewater flows from more than 300 properties, which were also published in a HaV report, were also presented and provide more data to keep in mind when dimensioning LPS systems. The take-home-message was nevertheless that the study does not provide an answer as to which flow to start from when dimensioning for development areas and that more studies may be required.
