The video is incredible! It really showcases the size and depth of the pool. Is that a drone you had chasing the bobcat driver? Sure would be one way to make them move quickly! The pure size of your pool must have made the clean up an epic task. Well done! Good luck getting your downstairs sorted. Hopefully by summer you can relax in the pool.

It was so amazing to see everyone step up, evaluate the situation, compose a plan, and come back so strong and fast! Damaged drywall and flooring removed, insurance claims filed, rebuilding, pool SLAM Processing, and of course, helping neighbors with all of the above too! A fine reminder that even when our emotions are intense, progress can still be made and we're never as alone as it might seem. Ask for and offer teamwork and see what happens!

Update on the pool project

*Replaced and Stained 400 LF of 6’ Cedar Fence with 2x6 rot boards
*Installed 11 Little Gem Magnolias
*Placed 14 cubic yards of Rainbow Gravel
*Installed 3 pallets of sod
*Added thermal covers and reel
*Heated up pool





Some fun calculations for pool nerds on the initial pool heat-up. [emoji851][emoji851][emoji851]

THEORETICAL

85,000 Gallons * 8.3454 Pounds/Gallon = 709,359 Pounds of water
Measured Temp Beginning: 59.5 Degrees F
Measured Temp End: 76.6 Degrees F
709,359 * (76.6 – 59.5) = 12,130,039 BTU

Master-temp HD 400K BTU efficiency: 82%
Natural Gas heat factor: 1.030

Theoretical Natural Gas BTU’s required: 12,130,039 / 0.82 = 14,792,730 BTU
Theoretical Natural Gas CF required @ 1,030 BTU/CF: 14,362 CF


ACTUAL

Beginning Meter Read: 47,300 Cubic Foot.
End Meter Read: 65,500 cubic foot
Metered consumption: 18,200 CF
2 pound meter factor: 1.1173
Total Cubic Footage Consumed: 20,335 CF
(Total BTU’s consumed: 20,945,050)

Price per cubic foot: $0.0062352
Price: $126.79

Assumption on difference between theoretical and actual: 6,000,000 BTU energy lost through *Radiant heat loss through cover and equipment
*Heating up pool shell
*Heating the dirt surrounding shell and pipes

Prior to the covers, I was losing between 1/4” and 1/2” of water a day to evaporation in the relatively dry air of a Houston ‘winter.’
That worked out to about 450 gallons a day, or 8,729 BTU/ gallon x 450 gallons ~ 4 MMBTU.
It wasn’t worth trying to heat it as it would cost $31 a day in gas just to counteract the evaporation portion of the heat loss.

I’ll keep an eye on the ongoing gas consumption to maintain swimming temperature water and update later on.

That landscaping looks great! Does it feel good to have it done?

How many covers are there? Do they all fit on the reel?

What is the reel at the end of the pool in the 1st pic? Thinking the swim lane markers but not sure.

How do you get the cover out of the "indents" of the pool?

It’s starting to feel good. Still have some deck work to finish up but it’s really close to being done done.

There are 5 sections. The main section (19’x82’) spools onto one spindle and the 4 side sections spool onto 2nd spindle. For practical purposes, we would really only be moving the main section for swimming during the winter. 76 degrees is perfect for lap swimming but a bit chilly for splashing around with the kids.

The reel at the end is for the (3) lane lines. Two of them are in the pool but the center line we left out for now.

When the weather warms up we will float the side covers to the end of the pool and reel them up on the 2nd spindle.

Those little trees don't pose a threat to the pool, do they?

Do the non-main covers attach to the main lanes cover or just float next to them?
Pool is lined with a 100mil root barrier along back wall. We went with little gem magnolias because their leaves are easy to scoop up, and they stay fairly vertical in their growth.

Side covers are hooked on lane lines and float separate from the main cover.
