Co-UDlabs _TA_IKT-03-TEST Testing the hydraulic performance of full-scale prototypes of a novel manhole

The design of manholes dates back more than 100 years and there is a lack of research on improvements in the geometry and configurations of manhole’ structures. This project presents an innovative manhole design suitable for use in narrow streets, particularly in hilly regions providing cost-effective and space-efficient solutions for separate urban sewer networks to improve and ameliorate the adverse environmental impacts of storm drainage systems. It addresses the challenges of disruptions to city streets and flooding events in downstream networks by mitigating the flow energy inside the storm chamber and enabling separate sewer pipes to be accommodated in one trench. The new shape of the manhole generates a new flow pattern for stormwater. It is therefore important to understand the hydraulic properties of the newly designed stormwater manhole chamber. The structural and hydraulic properties of a physical scale model of the new design have been assessed before at a lab at Liverpool John Moores Unviersity (LJMU) in the UK, and the results showed that the new manhole design provided structural integrity, stability, and significant improvements in hydraulic performance compared with the conventional system. The dataset of this Transnational Access Project - as a part of the Europen Union funded project Co-UDlabs (Collaborative Urban Drainage research lab communities) - is about the hydraulic performance of the new manhole system tested at a full-scale demonstration facility at IKT - Institute for Underground Infrastructure (Germany).
