How Inground Swimming Pools Work

All swimming pools function identically – no matter the size, shape or whether it’s a residential or commercial pool. Swimming Pools all use a combination of chemical treatment and filtration to to keep the water in your pool clean and circulating.


Most inground swimming pools work with a pump, filter, chlorinator and heater

Most inground swimming pools require the following components:

  • Basin
  • Motorized pump
  • Chemical Feeder
  • Water Filter
  • Drains
  • Returns
  • PVC plastic piping connecting all elements

When in operation, water is continuously pumped, filtered, chemically treated and returned back to the pool again. Your pools pump system keeps the water free of dirt, debris and bacteria. Heaters are frequently used to keep the pool water at optimal temperatures for swimming.

Step#2 – Permit Process

Your contractor will have the experience preparing the necessary paperwork to ensure that the permitting process with your local municipality goes quickly. Engineered structural plans are provided for all swimming pool designs and soil conditions. Comprehensive plans are submitted with all information required by governing municipality. Local service providers are alerted prior to excavation to ensure that underground utilities are not disturbed.


Your pool contractor is experienced at obtaining the proper building permits for your local area.

Step#3 – Pool Layout

Once the engineering and permitting is complete, your pool contractor will do a precise layout that ensures that your new pool is built per your approved construction plans. Upon your final approval, your contractor will be ready to dig! Your pool design is painted on the ground, allowing you to better visualize the shape and position of your pool in your yard. This gives you the ability to make design and pool location changes prior to excavation. Pool elevation, or height, is established to ensure proper water drainage.


Your pool contractor will do a precise layout to ensure your pool is built to specifications before digging.

Step#4 – Grading & Excavation

Excavation equipment is brought in and your pool contractor will begin digging the hole for your pool. This is an exciting part of the building process as your pool begins to take shape. Bobcats®, are generally used for most conditions. Your pool is hand contoured to ensure a smooth transition from your vertical walls and radius coves to the floor of your pool.


Excavation equipment is brought in to dig the hole for your swimming pool.

Step#5 – Steel Framing

Your pool contractor will place heavy reinforced steel, or rebar, inside the newly-excavated pool at the bottom, sides and top and completely wrap it around the perimeter of the structure to create what is called the bond beam. A four bar bond beam is used in the perimeter of your pool to increase the strength. Steel added to the walls and floors of the pool offers protection from expansive soil conditions on the outside and water pressure from the inside. Concrete blocks used for for spacers in the bottom and sides, providing a thicker, sturdier pool structure.

Step#6 – Plumbing & Electrical

Your pool contractor will install piping as well as the proper equipment to efficiently purify and clean your pool water. At this point an electrical crew will install power panels at the equipment pad, providing electricity to pool pumps and lights.

Step#7 – Gunite / Shotcrete

If your pool is made of Gunite or Shotcrete your pool contractor will begin constructing the shell of your pool with a concrete mixture that contains either concrete or sand or concrete and rocks. Under great pressure, this material is blown on with air, forming a tight bond around the steel rebar structure.  This enables your contractor to create a structure that’s worry free and offers a lifetime of enjoyment.

Step#8 – Tile / Rock / Masonry

Your pool contractor can construct many artistic effects through the use of decorative rock, tile and masonry. These are key design effects including waterfalls, grottos, jump rocks, and many other features to make your swimming pool truly unique and blended with the surrounding landscape.

Step#9 – Decking & Coping

At this point your pool is almost complete and your pool contractor will bring in crews to complete the decking and coping phases. This is the cap and surrounding walkways of your pool. Typically constructed of concrete, pavers, flagstone and travertine.


Choose from many different materials for your decking and coping

Step#10 – Interior Finish

The pool is almost ready to fill with water. At this phase your pool contractor will cover the entire interior of your pool with a high quality interior finish that seals, protects and enhances the look of your pool for many years to come.
