Water Volume in Above-Ground Pools

The Optimum water level in a pool is determined by the following picture. Pool heights are 52″ and 54″ (48″ being phased out) and your pool is filled to halfway up the skimmer. This provides equal parts of air and water going into your filtration system. Knowing this we can determine the optimum water volume your pool should hold for best filtration/circulation.

See The Charts Below:

Excavation Area Need for the Different Size Pools

Before purchasing a pool you may want to know the area the ground needs to be excavated to build a pool. You would first start with your city or town’s information regarding how far away from property lines, septic systems, existing decks, houses, etc. you need to be.

Area needed oval installation

Once you know where the pool can go you can then size up the area. The dimensions you see a pool size is not the area you need for installing a pool. The pool size is just the swim area and doesn’t account for excavation sizes and actual pool installed size.

Pro-Tip

Determine before excavation where the filtration system’s location will be (Approx). Excavate that area outward a few extra feet. Most cities and towns require electrical to be 5-6ft away from the finished pool wall. By having this space already excavated placing pumps and performing electrical duties will be easier.

Excavation and Pump Locations

The following chart will give you the excavation size needed for above-ground pool sizes.

Base Materials and the Amounts Needed for different Size Pools

Base material needed

There are two types of base materials and one common liner protection material that is laid over the base material. Mason Sand and Stone Dust are used as the base of your above-ground swimming pool. A geo-Textile material (Pool Pad) is then laid over the base material before the pool liner is installed. The following are the amounts needed for the different size pools.
