IS Code for Design of Water Treatment Plant

India has been facing severe water scarcity in recent times, making it crucial to design and maintain efficient water treatment plants. The Bureau of Indian Standards (BIS) has established an "IS Code for Design of Water Treatment Plant" to set standards for the design, construction, and operation of water treatment plants in India.

Scope of IS Code for Design of Water Treatment Plant

The scope of the IS code is to provide guidelines for designing and constructing water treatment plants that can produce safe and high-quality drinking water. The code provides guidelines for designing water treatment plants for surface water, groundwater, and seawater. Additionally, the code sets standards for the selection of appropriate treatment technologies, water quality parameters, and performance evaluation of the treatment plant.

IS Code Requirements for Water Treatment Plant Design

The IS code for water treatment plant design provides the following guidelines:

Site selection: Water treatment plants should be located in areas that are easily accessible, have sufficient water availability, and have suitable soil characteristics for the construction of structures.

Design criteria: Treatment processes, tank sizing, pumping requirements, and instrumentation should conform to the design criteria specified in the code.

Water quality: The IS code specifies water quality parameters that need to be monitored and maintained throughout the treatment process, including pH, turbidity, color, hardness, and total dissolved solids.

Treatment processes: The code provides guidelines for the selection of treatment processes such as coagulation, sedimentation, filtration, disinfection, and membrane filtration. The code also specifies the order in which the processes must be followed to achieve optimal treatment efficiency.

Operation and Maintenance: The code provides guidelines for the operation and maintenance of water treatment plants, including the monitoring of water quality, the calibration of instruments, the replacement of damaged equipment, and the maintenance of records.

Benefits of Following the IS Code for Water Treatment Plant Design

By following the IS code for the design of water treatment plants, stakeholders can derive several benefits. The code ensures that water treatment plants are designed and constructed to provide safe drinking water that meets the specified quality parameters. Additionally, following the IS code for operation and maintenance ensures that the treatment plant operates efficiently with minimum downtime.

Compliance with regulatory requirements: Compliance with the IS code ensures that the water treatment plant adheres to regulatory requirements specified by the Central Pollution Control Board (CPCB) and the State Pollution Control Boards (SPCBs).

Increased public confidence: By following the IS code for water treatment plant design, stakeholders can increase the confidence of the public in the safety and quality of drinking water supplied to them.

Conclusion

The IS code for the design of water treatment plants is a comprehensive guide that ensures the design, construction, operation, and maintenance of water treatment plants that produce safe and high-quality drinking water. Following the code ensures compliance with regulatory requirements and increases public confidence in the safety of drinking water. By adhering to the standards set in the IS code for water treatment plant design, stakeholders can create a sustainable future for the country's water resources.
