Among the suburban stations, four per cent of the stations scored within the range of 70 per cent to 80 per cent, whereas 14 per cent stations scored 50 per cent.

The survey also found that out of 720 stations, 25 per cent had provision for water conservation, 18 per cent of them had mechanism for rainwater harvesting and nine per cent had provision for water reuse.
