Re: Request to increase the Max. Daily Flow Rate
Dear Ms. Johnson,
We would like to increase the Max Daily Flow Rate on our IUP Number 4002 from .011
to .014. The reason for the request is because we want to dump the clean water from
our pressure tanks to the System rather than evaporating the water. Please fell free to
call me if you have any questions of need any additional information.
Sincerely,
Bill Hoover
