PLASTO STEEL PARK, is a premier industrial park in the state of West Bengal promoted by the West Bengal Industrial Development Corporation (WBIDC), the nodal agency in the state for industrial development. The Public Health Engineering (PHE) Department, Government of West Bengal, was entrusted with the responsibility of establishing a 20 MLD capacity Water Generation & Distribution facility to cater to the potable water requirements of the units in the industrial park.
PLASTO STEEL PARK had been assured of superior quality of service (QoS) by WBIDC. PHE faced the challenge of not only providing the required service but of creating a monitoring and control framework that would transparently assure that the desired service level has been sustained. In addition to the task of providing adequate potable water of desired quality adhering to the agreement with individual industrial unit, PHE also had the task of generating revenue from the units as per tariff structure for the potable water supplied.
PHE entrusted Shanta Colibri (India) Private Limited with the task of designing and implementing a framework that would efficiently perform the following key functions in Plasto Steel Park:
Install measurement devices that will have the desired accuracy and reliability.
Account for potable water generation, consumption by individual units and compute losses.
Monitor the quality and quantity of water supplied and the consumption pattern of individual units.
Monitor the energy parameters and consumption to determine cost of water production.
Visualize data to analyze trends, patterns and deviations.
Enable knowledge-based decision implementation process.
The Implementation Challenges
PLASTO STEEL PARK is located in a remote area and geo spatially spread over a large area.
The raw water intake facility and treatment plant is located at a distance from the Industrial Park.
Power supply is unavailable at most of the supply points to Industrial units, where available the quality of supply was poor.
The signal strength of mobile connectivity was limited.
Implementation Strategy of SCIPL- What we did
SCIPL adopted a conservative design strategy and adopted equipment and solutions that guaranteed a resilient system.
Relied on reputed OEMs, Endress + Hauser and Phoenix, to provide equipment that were suited for the design and guaranteed reliable performance. Engineered protection panels and devices to provide Ingress Protection and protect against power variations/surges (in cases where mains power was leveraged).
Adhered to industry standard and manufacturer specified installation practices stringently.
Adopted internal battery powered equipment to alleviate the unavailability of power issue at remote locations. The equipment were powered by field replaceable battery with assured minimum life of Seven years.
Leveraged GPRS over mobile network as the communication media. Adopted the light weight MQTT protocol. The publish and subscribe model of MQTT, with lightweight message packets, was the required solution under conditions where network bandwidth was constrained and unreliable. TLS encryption assured secure data communication between the sever and the IoT devices.
The management framework (SCADA) leveraged modules that have been proven in multiple deployments. The client was an integral part of the development ecosystem. The User Interfaces, Dashboards, Alarms/Alerts features, Analytical tools and Report generator addressed the exact requirements of the client and the process.
Implemented over an open protocol the framework will allow the client to plug in additional IoT devices on a future date, design their own dashboards and configure report generators.
The Outcome
A dependable system that provides reliable and traceable information for automation of system functions. Functions seamlessly in the absence of power and poor network conditions.
A paradigm shift to knowledge-based decision making system where user is guided through real time and historical data.
Visualization of information that keeps the plant personnel and management state aware.
Traceable and automated consumption information of industrial units addresses the specific objective of the implementation – Revenue Generation.
Continuous monitoring of power supply availability and quality at the intake station and in the treatment facility. The quality of supply is, pressure and quality parameters, is monitored assuring both PHE and the end consumers the quality of potable water provided.
The performance of the Pumps are continuously monitored providing for cost optimization and early detection of failures.
The analysis of trends and deviations in consumption allows early decisions on interventions required.
