    A decision support system is a way to model data and make quality decisions based upon it. It's widely used in the world for the various kind of process automation. Decision support systems that just collect data and organize it effectively are usually called passive models where they do not suggest a specific decision but only reveal information. An active decision support system actually processes data and explicitly shows solutions based upon that data. The water is found almost everywhere on Earth. Water resources like rivers, lakes, which provide water contain a lot of pollution, garbage unfit for consumption. Some diseases take time to present visible signs, but it does not mean they are inactive in your organism. To be clean, the water should undergo a number of treatments necessary to make it drinkable. So it is must to have purification technology for the waste water. So the waste water treatment plants act a major role in these issues. When considering the procedures taken after the water treatment process was always based on manual calculations and recordings. Water purification plants may interact with lots of manual processes. It means the process taking much time consuming. So the final evaluation and chemical, biological treatment process get delayed. So to prevent those types of draw backs there are some computerized programmable calculation and analytical techniques going to be introduced to the laboratory staff. To solve this problem automated system will be a solution in which guarantees the rational selection. The technological influence to the system is HTML, MySQL, php and some other web developing technologies. Current issues in the computerized water chemistry analysis are not much deep in progress. For an example the swimming pool water quality calculator. The validity of the system has been verified by test running and comparison with an existing plant data. Automated system will make the life easier in productively and qualitatively.

    Water Quality Index Calculation and Management System

    Water quality data recording and manipulation has always been a manual procedure in local water resource management agencies. The Water Quality Index Calculation and Management System was developed as a partial solution for these shortcomings. It calculates water quality index automatically after entering the basic data into the system. It can accurately generate necessary reports daily, monthly and yearly. Web- based online system has been chosen to facilitate the Water Quality Index Calculation and Management System. Open source PHP and SQL were used to develop a comprehensive design program for a waste water treatment plant.With the use of powerful problem solving feature of the HTML this system was developed. The program can also be used to check the design details of an existing plant to know the expansion works needed for increased hydraulic and organic loadings occurring in future.The purpose of this study is to present the development of a modular online system package for simulating the performance of the selected treatment.The computer program for the design of water treatment plant was test-run and the results were compared with those of the existing plant. The program is interactive. The program has been fed with relevant input data for each unit of treatment plant and executed. Data are entered as and when necessary as per the guidance obtained from the program.Major output of this system is giving a final conclusion about the treated water in a water treatment plant. Also it calculates values for the water quality parameters like turbidity and total water hardness etc. Different user can get customized details and information from the system.The proposed system benefits to all the people who use water quality reports by increasing the efficiency and mobility in an effective manner. Also waste water treatment plants play a major role in the system. The main goal of the Water Quality Index Calculation and Management System is to popularize it among water professionals.
