Siva Ramalingam Nurtures Around 300 Trees using Greywater From His House


Siva Ramalingam devised a way to reuse greywater to water and maintain trees in his neighbourhood.

Product or concept

Devised a method where the greywater from his street is used to maintain the neighbourhood trees.

Problem being solved

To increase and maintain the green cover in the city’s streets.

Process or technology involved

  • Water from bath and kitchen usage is channelled into separate drums that are installed like sumps.
  • To avoid any kitchen waste to get in the way, a filter is fixed that strains away everything.
  • The water is then pumped out through a small motor and let flow along the street through a simple underground pipe network and released through taps at different points. 

Sustainability benefits

  • Using simple plumbing network, reduces amount of greywater entering drains.
  • Reduces the heat during summer seasons due to increased green cover.
  • Reorganizing greywater plumbing network in residential areas reduces requirement for water sources utilised specifically for city trees’ green cover maintenance.

User segments that will benefit
