Supply, Installation and Commissioning of Internet of Things (IoT) based water quality monitoring system at Sembakkam Lake, Chennai

Request for Proposal June 2021 A. PURPOSE

The Nature Conservancy is seeking proposals from vendors for the design, supply, establishment, and annual maintenance of Internet of Things (IoT) based water quality monitoring system at Sembakkam lake, Chennai.

B. BACKGROUND

The Nature Conservancy is a global environmental nonprofit working to create a world where people and nature can thrive. Founded in the U.S. through grassroots action in 1951, The Nature Conservancy has grown to become one of the most effective and wide-reaching environmental organizations in the world. Thanks to more than a million members and the dedicated efforts of our diverse staff and over 400 scientists, we impact conservation in 72 countries and territories: 38 by direct conservation impact and 34 through partners. Our mission is to conserve the lands and waters on which all life depends.

The Nature conservancy along with its partner organisations Care Earth Trust and Indian Institute of Technology - Madras are working towards restoration of urban wetlands. Together we are working on the restoration of the 100-acre Sembakkam Lake using Nature Based Solutions (NBS). This will act as a demonstration pilot showcasing holistic and science-based wetland restoration methods. The pilot project aims to improve the storage capacity and water quality of the lake, creating an ecologically designed recreational space and improved biodiversity habitat for the native flora and fauna. With the technical expertise provided by FINISH consortia (a consortium of FINISH Society, Indian Leather Institute Foundation and the Solutions centre), we are setting up a nature-based wastewater treatment system at the lake to treat the wastewater entering the lake. Our target is to treat the wastewater and improve the water quality of the lake to Category D of the surface water quality standards prescribed by the Central Pollution Control Board (CPCB) for propagation of wildlife and fisheries. Through these efforts, the project aims to impact revival of water bodies, restoration of biodiversity habitats and enhance quality of life of the people by demonstrating a replicable model for restoration of wetlands.

Through the course of this project, we are engaging with other key stakeholders in the city including various local and state government bodies, private sector, academia, and NGOs to impact wetland conservation efforts at scale. The technical wing of IBM service corps is supporting the development of the water quality monitoring design using Internet of Things (IoT)-based technology. Based on the learnings from our work at this lake, we plan to develop recommendations and guidelines for sustainable and scientific methods for wetland restoration and long-term monitoring for sustainable outcomes.

C. EXPECTED OUTCOMES FOR THE WATER QUALITY MONITORING

In view of long-term monitoring and to perform adaptive management of the restoration approach at Sembakkam lake, we propose to monitor the restoration outcomes on a regular basis post restoration. Water quality is one of the key health indicators of the lake. We plan to monitor the water quality parameters using IOT based systems. This approach enables for ease of access and demonstration of advanced technologies for lake monitoring.

We intend to monitor selective water quality parameters that represents lake health and indicate the working efficiency of the wastewater treatment system installed at the lake. The water quality parameters that we propose to monitor are pH, temperature, electrical conductivity, total dissolved solids, turbidity, dissolved oxygen, and free ammonia. The system should be set up in such a way the lake water quality is regularly monitored by the project proponents (TNC and its partner organisations) and in the later stage made public to other stakeholders such as Public Works Department ( PWD), community and academia. The online monitoring is expected to provide alerts/ red flags on dashboard application if the water quality of the lake goes beyond the acceptable limits of CPCB surface water quality standards (for Category D for wildlife and fisheries propagation). Hence the monitoring system is expected to have in place the required devices and mechanisms for triggering alerts to stakeholders, if there is any deviation observed beyond the desired water quality limits.

D. SCOPE

The scope of work for the vendors shall consist the following.

- Site Assessment and development of a suitable plan for installation of IOT based online water quality monitoring system as per the technical road map prescribed in Annexure II. This includes identification of a suitable location and space for placing the sensors and all services required to establish the complete IoT monitoring system, determining the required devices/ components and their quantification. - Supply and installation of online water quality monitoring sensors for pH, temperature, electrical conductivity, total dissolved solids, turbidity, dissolved oxygen and free ammonia. - Set up of online water quality monitoring system with all essential accessories including but not limited to water quality sensors, control panels, underwater cables, dashboards, providing network connectivity to end users, developing a security system etc as per Annexure II. - Development of a dashboard for visualization and analysis of data collected from water quality sensors such as via graphs, charts etc. - Development of mechanism to send alerts to users if the water quality of the lake goes beyond the prescribed limits of CPCB surface water quality standard D meant for propagation of wildlife and fisheries. - Devising a security mechanism for minimising risks from tamper, theft, damage from public access, movement of boats and damage by any animals. - Regular maintenance of the water quality monitoring system for a period of two years. - Developing a plan and timeline for implementation of works. - Solution should be compliant to but not limited to the requirements prescribed in Annexure II (No of Users, Data Frequency, Data Back-up policy, Data Security, System Availability, etc.).

Note:

- The IoT interventions should be designed in a manner that can withstand an event like flood and drought. - The vendor will need to work in close coordination with the wastewater treatment solution provider so that the water quality monitoring sensors are placed at the outlet of the wastewater treatment systems at site and at a place where water will be available throughout the year.

ANNEXURE I

ADDITIONAL INFORMATION ABOUT THE SEMBAKKAM LAKE

Sembakkam Lake (also known as Hastinapuram Lake) extending over a 103 acre is one of the lakes draining into the Pallikaranai Marsh through a cascading system of lakes. It is located at 12.9234° N and 80.1588° E. The current water storage capacity of the lake is 10.12 million cu.ft with a peripheral length of 3.309 km.

Figure 1 Sembakkam Lake and its inlets

The lake extends over three local bodies covering Sembakkam Municipality on the Southern and Eastern sides, Pallavaram Municipality on the Northern side and Chitlapakkam town panchayat to its Eastern side.

There are huge number of encroachments along the north-western boundary from which sewage is being directly let into the lake and can be attributed as the non-point sources for contamination of lake by sewage. The western boundary, being upstream, receives inflow from 22 inlets as shown in the figure above. These are primarily storm water drains to carry the runoff in the catchment area and the excess flow from Selaiyur, Chitlapakkam and Rajakilpakkam lakes. Due to the lack of proper sewerage system, the sullage from the house sewers is being directly discharged into the lakes through these inlets. Annexure II
