Indian Institute of Technology, Madras (IIT-M) asked the Corporation to follow its designs for the stormwater drain work.
Story so far: The drains on Ramasamy and Lakshmanasamy Salai were higher than the houses, putting them at risk during floods. In some stretches, the drains are being constructed in bits and pieces, and aren’t connected to each other. IIT-M has asked the Corporation to follow its tried and tested design.
- The IIT-M design has the top slab on the road level instead of above it. The water inlets should be at road level.
- This will enable the draining of the runoff. The gradients of the stormwater drain should be maintained so that collected water can flow through it without stagnation.
Keep a check: Experts say a live monitoring mechanism is needed to ensure the designs are being followed. IIT-M could conduct random checks for any flaws.
