The following features should be added to Infoworks ICM for modelling temperature impacts for Heat extraction or heat insertion projects:
- Sewage temperature to be added in WWG file as a pollutograph parameter and can also be defined in a diurnal pattern to consider trade temperature profiles
- I&I temperatures can be extra entered
- Linear heat losses can be defined for standard pipe configurations towards an equilibrium temperature
- Temperature mixing at each node, based on WQ simulation engine
- Heat extraction or insertion possible at any model node
In-sewer water temperature monitoring has been around for a while. It is useful for identifying groundwater infiltration, potential heat recovery locations, optimising chemical dosing, predicting H2S build up and other key sewer processes. A dynamic in-sewer water temperature model as part of ICM simulations would enable temperature verification within a network, opening up a whole new area of model directed wastewater planning interventions.
