Sensor network to map and predict pollution, effluents in Godavari

A group of U.S. researchers is working on a system to map undulating pollution trends in India’s second longest river- River Godavari.

  • The exercise is part of a Bill and Melinda Gates Foundation project to support the programme of the Administrative Staff College of India (ASCI) to provide city-wide sanitation improvements in urban Andhra Pradesh.
  • Sensors to monitor river pollution are an emerging technological approach in India.
  • Using a mix of methods, including satellite-monitoring, traversing stretches of the river to collect water samples and using special sensors to measure bacterial and chemical pollution, the researchers are trying to develop a cost-effective forecast system.
  • Through cloud-based data collection and real-time mapping systems, the research and implementation teams intend to demonstrate the importance and value of detecting and anticipating pollutants that enter the river in the form of human waste, organic materials, and chemical contaminants.

Objectives of the project:

  • The long-term objective is to be able to inform State officials and citizens of a probable spike in, say, levels of dangerous microbes or effluents, similar to weather and air pollution forecasts.
  • Also, it is to be able to access “raw data” that could be used to inform the efficacy of a proposed faecal sludge treatment plant and whether behavioural interventions — including incentives or punishments — to restrict activities that pollute the river could actually work.

Godavari River:

The Godavari is the second longest river in India after the river Ganges having its source at Triambakeshwar, Maharashtra.

  • It starts in Maharashtra and flows east for 1,465 kilometres (910 mi) emptying into Bay of Bengal draining the Indian states Maharashtra (48.6%), Telangana (18.8%), Andhra Pradesh (4.5%), Chhattisgarh (10.9%), Madhya Pradesh (10.0%), Odisha (5.7%), Karnataka (1.4%) and Puducherry (Yanam) through its extensive network of tributaries.
  • Measuring up to 312,812 km, it forms one of the largest river basins in the Indian subcontinent, with only the Ganges and Indus rivers having a drainage basin larger than it in India.
  • In terms of length, catchment area and discharge, the Godavari river is the largest in peninsular India and had been dubbed as the ‘Dakshina Ganga’ – the South Ganges river.
  • The major tributaries of the river can be classified as the left bank tributaries which include the Purna, Pranhita, Indravati and Sabari River covering nearly 59.7% of the total catchment area of the basin and the right bank tributaries Pravara, Manjira, Manair together contributing 16.1% of the basin.
  • Pranhita is the largest tributary covering about 34% of its drainage basin.
  • The Coringa mangrove forests in the Godavari delta are the second largest mangrove formation in the country. Part of this has been declared as the Coringa Wildlife Sanctuary, renowned for reptiles.
