Condo Management Not Doing Their Job -- Owner Rights???

I own a Condo in Mass. I received a letter from the condo association that they have a water/sewer bill of $39,454.65 It doesn't indicate how long it took for this amount to accumulate. I don't think the bldg. manager is running things correctly.

What rights do I have to make sure all building bills are being payed on time?

Also how can I make them fix water leaks in the bldg. that should have been fixed 3 years ago after part of the roof blew off?

Thanks!!!
