As I mentioned earlier, We are filling our pool using rainwater this year.

Rainwater collection for the pool.

I have also tied in the back of the house since this picture.

The good?

  • Natural (ample over time) water source.
  • Doesn’t tax the well and pump.
  • Water is naturally softened and balanced in PH/alkali content.

The bad?

  • Until the pool is nearly full and the pump/filtration can be activated, the untreated collected water is stagnating in the sun. In the interim, I set up a simple sump pump to run through the filter system to keep the water moving during this filling stage.
  • Collected water is (or quickly turns) greenish brown. Much appears to be sediment that can be brushed/swept away. Once the level reaches the filter basket and the main pump is active, a thorough vacuuming of all pool surfaces should greatly clear up the murkiness and the chemicals should do the rest.

Update 20240518: With the pool now full (mostly pump/well at 1″ per hour – as the forecasted deluges never materialized), I am switching into clean up mode. The problem is it appears our 1 year old pump is now bad. After a few weeks of collecting stagnant untreated water, it was quite putrid originally. Once I realized our pump wasn’t pumping, I swapped in a sump pump I had on hand and forced that through the pump/filter housing. After a few hours, the water cleared up considerable. However, what I really need to do is thoroughly vacuum every surface to get all of the pollen and other sediments that landed in the pool along with the seeds from the various trees. However, I can’t do that until I have a working pump running from the debris basket to the pump/filter and that won’t be delivered for a few days yet.

Damn. And we’ll be getting close to 90 tomorrow.

UPDATE 20240616:
The completed pool project is working wonderfully. Here is my final solution.

Besides making MacGyver insanely jealous, there is a method to the madness. All rainwater from the gutters flows into the pool via the elevated pipe in the middle. It is elevated because that is a regular walking path. Then, starting on the far right, that gray object beneath the ladder is where the water is supposed to flow back into the pool after the pump. However, it wasn’t until the pool was filled that I discovered this was plugged (maybe a mud dauber) so I bypassed this and have the hose from the pump (white hose beneath ladder) flowing directly into the pool. I then installed a valve below the new filter basket so I can work on pump/filter issues without the pool draining down to the bottom of the basket. The nearly horizontal hose traversing right to left is for when we flush (backwash) the sand filter and discharges close to the ground. The little “U” shape hose in the middle does nothing. This pool came with multiple options and this could be used for a heater but we don’t need it so we simple ran a hose from one connection to the other. I could also simply plug each one but haven’t found anything suitable. The hose coming from the left is another “option” that wasn’t used. However, now with rainwater pouring in during storms, this keeps the pool from overflowing and the water depth can be adjusted simply by turning this fitting to the desired level. All overflow water flows out the same discharge as the backwash/rinse modes of the sand filter. On forecasts of heavy storms or rain, I’ll hook up our RV drain hose to that discharge so the flood flows downhill away from the yard.

I know that is more than anyone cares to know but just know this set up is working “swimmingly”. (Sorry, I couldn’t resist).
