As Bengaluru struggles to stop sewage from entering stormwater drains, a recent K-100 waterway project is using Israeli techniques to purify aquatic plants.
Story so far: Despite the BWSSB relaying pipelines to divert sewage, a large amount still flows through the drains. To help fix this issue, they are in talks with private firms that plant sewage eaters.
- The technology is environmentally friendly and uses a team of experts who select the right combination and amount of aquatic plants to enter the drains.
- By using aquatic plants, the BWSSB aims to beautify the surrounding drainage area as well.
Issues faced: Experts noted that it would be difficult to provide enough space to let these remedial plants grow. There has also been a big delay in the work, with only 60% being finished. BBMP officials have blamed the BWSSB for the delay, saying that sewage drains should be managed better.
