Water bill increase from washer & dryer

[Bharath Janakarajan]

I have been cautioned to avoid washer/dryer in building due to water bill increase. I live in NJ and think it would be a good amenity to attract tenants. This is a 2 family (3 bed,1bath units) and there is washer/dryer already available in the basement. On Moderate to heavy usage, want to get thoughts and experience on what kind of increase in water bill is expected, are we talking 25% or are we talking about 50,75 or 100%.

Thanks,
