Wellington Water Live Modelling
❄
| Wellington Water Limited (WWL) are Ngā Wai Hangarua (stewards of the water) that aspire to Te Ika Rō Wai, a state of harmony between water, environment, and people. WWL follow the principles of Te Mana o te Wai and partner with mana whenua to value the mauri (life force) of water and the deep connection between water and people. WWL seek to realise higher benefits from increased access to data and better computational capabilities. Live and real-time modelling solutions present the potential to improve operations and make more informed decisions to enable better understanding and operation of networks. These advancements provide opportunities to manage networks and ensure the efficient delivery of water services to customers. WWL has undertaken a project to adopt live network models for the wastewater networks that WWL operates. The aims are to improve operational forecasting, provide early warning, advise emergency management, and inform resource consents. Info360 / ICMLive is a software solution that integrates InfoWorks ICM catchment modelling with real-time data acquisition and analysis. This will allow WWL to receive forecasts based on past and current observations and future rainfall predictions. High confidence real-time modelling requires good data input. WWL are trialling the method with the Miramar catchment, a subset of the Wellington strategic model. This model has been calibrated and is simplified so that simulations can run rapidly and with sufficient accuracy for their needs. WWL have derived processes to transform various data sources such as from SCADA, Moata, Lutra, NIWA, Hilltop, and YR and store it in a centralised data warehouse. The data warehouse has potential further benefits beyond the use case for real-time modelling. The data outputs from ICMLive aim to enable WWL to perform various tasks such as automatically acquiring and quality checking data, receiving instant alerts for action, conducting scenario analysis, performing risk assessment, and improving operations. The aspirations of this project are to mitigate overflows into the harbour and enhance water quality, thereby ensuring a safe swimming environment for the public; increase catchment knowledge and realise potential quick wins; and demonstrate the benefit in resolving their pressing business issues and roll out to additional catchments. |
