CityWat

CityWat enables a user to create a model object, which has a range of sub-models that can be added to it. Each sub-model represents a different water management process (e.g. abstraction, distribution, etc.) at the city scale. Information is shared via updating the model object's state variables, thus updating these state variables correctly ensures preservation of mass balance. Model objects also have a range of parameters that are used in the various sub-models. These parameters are currently set to represent the lumped values for London's urban water cycle. Implementation of options or interventions is simple to do in CityWat, provided that the options can be translated to a lumped city scale. We provide a list of options at a London scale.

When running in simulation mode, CityWat simply loops over all of the included sub-models for each timestep - daily in its current form. This provides extremely fast run times (under 1 second for over 40,000 timesteps on a 3GHz PC).

CityWat is not a GUI-based software and requires basic programming skills to use. We made this choice because each city's water management is so unique that attempting to generalise all possible urban water cycles into a unified software was considered unfeasible. Indeed there are tens of existing GUI-based urban water cycle softwares available, yet we considered none suitable to model our problem without significant and complex modification. We decided it was far easier to make a simple but highly customisable software.

Statement

The CAMELLIA project ( https://www.imperial.ac.uk/environmental-and-water-resource-engineering/research/camellia/) required the creation of a water management model for London that covers supply, wastewater and river quality. Our aim was to perform mass balance calculations and make operational decisions covering the entire urban water cycle at a lumped citywide scale. We wanted a software that is simple but highly customisable so that it can accommodate the unique operational situation that London's water finds itself in. We could not find an easy to use and open-source modelling software up to the task. Thus, we created CityWat.
