Full Description

The use of SCADA systems at water treatment plants and water distribution networks has beenincreased considerably during the past decade. Recently our drinking water qualities have beendiscussed intensively, thus, it has been concluded that it is necessary to get more accurateinformation about how our water distribution networks really operate and control. It is clear thatsome of the water quality problems can be solved by optimal operation of the distributionsystems.In this study, some information about continuous monitoring of water quality and quantity ofdistribution systems and potable water reservoirs of Istanbul City is given. Istanbul is one of theworld's most important cities in terms of history, culture, trade and tourism and its population hasreached over 12,000,000 and total daily water consumption is around 2,000,000 msup3/sup/day.Control of the water distribution systems of this metropolitan city has been operated with aSCADA (Supervisory Control and Data Acquisition) system which consists of seven subsystemsgathering information about flow rate, water quality parameters and pressure, and water levels inreservoirs and dams. With the increasing awareness of microbial and chemical contaminants andtheir potential public health impacts, continuous monitoring of water quality parametersthroughout the distribution system becomes critical. Thus, safety and reliability of distributionnetworks are baseline components of management of water flow rates in the system. Since2,000,000 msup3/sup/day water is serviced to Istanbul City, interruption of water service results in critical problems of significant disruptions to fire protection, commercial establishments, andindustry. Therefore, the present SCADA system is utilized to increase reliability of the metropolitancity water distribution systems to prevent short-term interruptions of service, and prevention andmanagement of specific accidents and emergencies. The purpose of this work was to examine the present SCADA system and its subunits and topropose rehabilitation and upgrading framework for system renovation. Other components of awater distribution system will also affect the overall system reliability but are not considered inthis analysis. Includes 8 references, tables, figues.
