Monitoring systems in water supply

Modern water supply systems require continuous monitoring of water levels in water springs, water pressure in pipelines, water flow, residual chlorine, pump status and other required parameters and their transmission to a remote control center.  In addition to remote monitoring, the system must also provide safe remote control of equipment used in water distribution: water pump operation, shut-off valve regulation, chlorine dosing equipment etc. In addition, the system must also provide feedback and information on the execution order. In addition to the above mentioned system, it is also necessary to enable the reception and transmission of signals and information of measurement control equipment which will, if necessary, be upgraded to the system in the future.

The present situation as well as the future development of water supply systems supplying water to certain broad areas necessitates the introduction of a system of remote monitoring and management of water supply facilities, ie the entire water supply system, with a view to providing quality, reliable and economical supply of consumers with potable and industrial water.

When designing a project for the management and supervision of a particular water supply system, the following elements are particularly taken into account: Satisfying the hydraulic conditions in the system, ie maintaining the required pressure, volume and flow of water, ie ensuring sufficient amount of water in all water tanks; reducing the amount of electricity consumed, in such a way that the available quantity of water is optimally distributed for the gravity supply of the consumer. Reduction in the amount of electricity consumed is carried out so that tank filling is carried out predominantly or completely, if possible, during the period of lower electricity tariffs, while for a longer period the water tank tariff is not full or full to the level  obtained on the basis of the statistical forecast the amount of water is sufficient until the lower electricity tariff period. This forecast depends on the time of the day, aswell as the weather conditions. Based on the forecasted amount of water required, water levels are to be charged (during the period of lower electricity tariffs there is no problem of forecasting, but reservoirs full to maximum capacity); Monitoring of water loss in the system, based on flow metering on individual pipelines, ie water level in watercourses; notifying the person at the Dispatch Center about system malfunctions.

These conditions dictate the introduction of such an information system that quickly and reliably informs about all conditions and changes in the water supply system.  It is very important that the information system is implemented in such a way that all devices and portable protocols fully meet all of the above mentioned requirements.

Long years of experience in the implementation of the system of remote monitoring and management of water supply systems, legal changes and environmental awareness have resulted in the development of innovative solutions in the water supply sector:
An application for the production of an inventory of the quantity of water involved
Application for detecting and reducing losses on water supply systems
