Let’s take a look at how we can solve the problem of river pollution and improve the quality of the river.


Example – River Pollution

Background & Impact of River Pollution in Malaysia

  • Malaysia has 120 rivers that are sources of water supply, and 43 were located in Selangor
  • Sungai Selangor provided water to 60 percent of residents in the Klang Valley. The water treatment plant at Sungai Selangor cost about RM900 million
  • Nearly 40% of rivers in Selangor are known as dead rivers. Klang and Gombak rivers are among the most polluted water systems in Malaysia.
  • 64 cases of river contamination occurred in the past five years, with 15 in the last year alone
  • In Selangor alone, the amount of solid waste could rise to 6,000 tons by 2017. More than 19 percent of waste end up in the drains, which then causes flash floods and other health problems.
  • Consumers will face an increase in water tariffs if the current pollution of rivers in the city continues to worsen

Problem Statement

  1. What are the pollutants in the river?
  2. What is the pollution level?
  3. When is the highest pollution detected?
  4. Where is the location of contaminants?
  5. Who is contributing to the rise in pollution?
  6. How to control the pollution level?
  7. How much is the pollution level?
  8. Why is the pollution rising at a particular time?
  9. Why is the pollution rising at certain locations?


  1. IoT Middleware (FAVORIOT) 
  2. River water sensors (PH, residual chlorine, turbidity, suspended solids, COD, BOD, conductivity, and dissolved oxygen.)
  3. Water level sensors
  4. Network infrastructure (Wifi, 3G)
  5. Visualization Dashboard
  6. Analytics
  7. Crowd-sourced violation information (mobile device)
  8. GPS input
  9. Hydro morphology e.g. depth, width, flow
  10. Water temperature sensor
  11. In-situ (manual sampling)
  12. Weather sensors

Using FAVORIOT to Create IoT Dashboards

Once you have identified the relevant sensors (either developed in-house or purchased from third parties products), you can integrate, collect and aggregate all the data into a single IoT platform (i.e. FAVORIOT), which can easily create IoT dashboards via the available widgets or extract the data and create customized dashboards.
