Pool water flow issue
Doug,
Thank you for your prompt attention and response, we will be discussing pool operations with staff to make sure we do not have issues going forward.

Doug,
Works for me. As I said, our criteria for success is no overflows. We have no problem with discharge into the sewer system. The other part of the email were just options if you wanted
to adjust the discharge point to use the storm system.
Like your idea of adjusting the system pumping capability to make it “operator proof.”

Doug,
I understand your response, however at this time and during the permitting process which included discussions with COAB staff, our teams understanding was that the discharge was to go
directly to the clubhouse sewer system. The system is installed as staff had directed. The direction was to discharge into the sewer system at the rate not to over tax the system.
The system is currently in good working order and is being discharge routinely, there have been no issues prior to or after the pool overflow incident. Unfortunately due to an error
on our part the system overflowed which we believe was inadvertent. The proposed resolution is adjusting the pumps to a lower RPM to reduce the flow, our pool contractor has advised
that this can easily be accommodated. In addition, the club management can effectively provide operational instructions and post signage. Re: draining the pool; the pool is new therefore
I do not see it being drained for years, the marsite should last 12 to 15 years therefore at that time the club can permit draining the pool into the storm system or discharge into
the lawn area for treatment.
As always the club management and development team will work with the city to meet regulatory requirements and find a solution.
Respectively,
Doug Maier

Bill,
We appreciate that training and operation of the pool discharge as designed should eliminate the sanitary sewer overflow potential. Success to us is no overflows.
As part of this discussion, we researched the discharge of pool water into the stormwater system and found it is not allowed by our NPDES permit and would be consider a violation we
would have to report. Discharge to the stormwater system from the pool would have to be dechlorinated. There was no chlorination limit mentioned in the regulations just that discharge
of chlorinated pool water is not allowed. Possibly there is a way to do that with discharge into a grassed area or sand trap, but that may be an operational issue for the golf course.
Maybe ABCC could test the discharge downstream to confirm it is chlorine free before it hits the ponds.
We would be happy to review any stormwater discharge alternative, if requested.
Thanks,
Doug

All:
I apologize for taking this long to respond but I had surgery Monday and figured it would be best to wait until I was off pain pills.
As you all may recall or read in Rick’s email string attachment, the agreement was that only one filter would be backwashed at a time. Apparently, Billy Parry did not pass this info
along to Brad at Crown Pools, so they put all 5 filters in backwash at once for an hour or more to bring the pool level down, or so I am told. Normal operation is as I explained in
the emails back in April, so as long as the restriction to do one filter at a time is followed, no problem will occur. We have suggested posting a large sign above the filters with
this requirement and properly training whoever is going to operate the pool.
The pool was over full because the overflow in the collector tank was set too high. My understanding is this has been corrected. The overflow is a 2” gravity pipe. It is too small to
cause any issue in the collection system. I believe it is currently connected to the backwash sump. It may be redirected to the closest storm drain, if desired, as it is basically
a mechanism for disposing of rainwater. It allows the pool to return to normal level slowly. Why this was not allowed to happen, after correcting the overflow height, and the pool was
“pumped down” I do not know.
Contact me with any questions.
