The award for best sewerage and drainage services has been given to Chandigarh for being the only city in India which has prepared a concrete action plan to treat its sewage effluent as per the Central Water Pollution Control Board standards before its disposal into natural streams. The coverage of waste water network is 100 per cent. Around 59 per cent of the waste water is treated for secondary treatment and 14.25 per cent of waste water is recycled which is used for irrigation purposes in green belts, parks etc. The cost recovery in waste management is 80 per cent.

The MC is also executing a project for conservation of drinking water by harvesting tertiary treated sewage for irrigation of green spaces under JNNURM at Rs 36.80 crore. For this project, a 50 MLD Sewage Tertiary Treatment Plant is being installed at Diggian which will treat sewage water up to tertiary level.
