Swimming in Delhi

I used to travel to India once or twice a year, but, with one rare exception, never got in for a swim. The last time I was there was 2010 and they were upgrading a pool for the Commonwealth Games (d2010.thecgf.com/dr_sp_mukherjee_swimming_stadium). I am heading back in early July and wondered if anyone has swum there? If so, can you point me to any website that might have hours (I find a lot of references to it and phone numbers, but no details on schedules)? If you have swum in the greater Delhi area (I'll be staying in Gurgaon) and can recommend any other pool, I'd greatly appreciate it.
