Just posted more photos as well...
To start our pool is actually 55m long, but we have two Stark bulkheads, each 2.5m wide that make the pool 50m. With the bulkheads the pool can be configured to two separate 25y or 25m pools. At the end of the photo of the diving board is also jumbo-tron, 2 stories wide, by 1 story tall.
The pump room also has its own pdu ventilation system and dehumidifier. The chlorine room too has its own ventilation system.
The box behind the co2 tanks is actually a controller for the co2 tanks, showing use which tank is being used, how much is left, and the output psi. It also includes tank heaters. The yellow tank next to it is where the co2 is mixed with the pool water before going into the pool. We also have a co2 detection system, with alert features on each entrance to the room.
We also use muriatic acid, but in our usage, its costs more for acid than co2, if you take out the cost of the co2 system.
The acid we use is 41%, and we connect our acid pump straight to the barrels, without mixing. I just have to wear a gas mask when changing out the barrels.
The whole pump room except where the paco pumps are is actually above the grade of the pool deck, and at ground level. The pit where the pumps are 20’ below the pump floor, and are 5’ below the pool deck. The pumps pull water from the surge tank, and when the draining the pool can’t be used after about 5’ of water has drained. The white pump to the right of the paco pumps is our drain down pump and agitator pump. I have pics of the agitators in action, as well as one showing the strainer.
The strainers need only be cleaned about 5 times a year, and we use a powerwasher to clean all of the lent and debris they collect.
The sand filters allow us to only have to backwash about 6 times a year.
The uv system, though expensive, was installed for crypto and dbp control as it allows us to keep the chlorine at about 1.6 ppm.
Also in the picture with the sand filters, you can see the uv control unit on the wall, and our becys orp/ph controller.
