ABSTRACT
The modern approach to water supply network management and operation is related to the use of modern solutions from both technical and strategic perspectives. Apart from practices promoted by International Water Association (IWA) (active leakage control, pressure management, speed and quality of repair, pipeline and as- sets management), water demand prediction systems are the future. Preparing short-, medium- and long-term water consumption forecasts is the key factor these days. Short-term simulations, mainly those covering the period of 24 or 48 hours, are used to optimise the operation of pumping stations and to resolve current exploitation issues, whereas long-term analyses, covering more than one month or year, are said to support the decision-making process regarding the design and development of water supply networks. Medium-term predictions, covering weeks, are used to create time schedules for the maintenance of water supply networks and develop failure prevention procedures. Due to the lack of assessment teams and proper assessment tools, the majority of water and sewerage companies store registered time series without thorough study of the data. Information regarding the current operating status of the water supply network included in the series is not properly used and irretrievably lost.

Pantura Water Quality: Comparing the Pollution Distribution Model of Comal River and Garang River
ICBBB '18: Proceedings of the 2018 8th International Conference on Bioscience, Biochemistry and BioinformaticsSea is the estuary of rivers on land. In the sea all kind of pollutions carried by the river flow will be accumuated, which make the sea water quality worse than the river itself. Comal river and Garang river is two of the few river that flows into the ...

A fully adaptive forecasting model for short-term drinking water demand
For the optimal control of a water supply system, a short-term water demand forecast is necessary. We developed a model that forecasts the water demand for the next 48 h with 15-min time steps. The model uses measured water demands and static calendar ...
