Louisville Pool Closing

Yes, following Louisville MSD's pool draining guidance. Do not drain during or within 48 hours after rain, dechlorinate first and let the pool sit at least 10 days after chemical treatment, then discharge no faster than 30 gallons per minute to a grassy area large enough to absorb it or a sanitary sewer cleanout on your property. Never direct the water toward neighboring properties. Confirm the details with MSD before draining.

Before the first hard freeze. NOAA's 1991 to 2020 normals put the median first fall freeze on November 7 at Louisville International and November 3 at Bowman Field. The airport also averages about 74.0 nights a year at or below 32 F, so water left in pool pipes, hot tub plumbing or fountain lines is at risk every winter. October is still mild with an average high of 70.5 F, so closing too early invites algae under the cover.

Jeffersonville's Wastewater Billing Adjustment Policy points pool owners to the city's drainage ordinance, which requires pool water to be discharged into the storm water system or the ground. Pool chemicals are not to reach surface waters or storm drains, so the water must be neutralized first. A pool drain connected to the city sewer has to be rerouted to a storm sewer before a pool fill credit is granted. Confirm with the city's Wastewater Department before draining.

Once the season is over and temperatures are consistently falling, but before the first hard freeze. Closing too early in warm water can encourage algae to establish under the cover, while leaving it too late risks the freeze damage the closing exists to prevent.

Balancing the water and adding winter treatment, lowering the water to the correct level, blowing out and plugging the lines and draining the pump, filter and heater. Accessories are removed and stored and the cover is fitted. The order matters, which is why it is done as one visit.
