His 500,000-gallon aquatic masterpiece is the result of dedication, creativity, and a dream that refused to fade.

Thornton’s dream of a massive backyard pool began nearly three decades ago. Inspired by his love for swimming and a desire to create a unique family retreat, he started building in 1993. The initial phase involved digging a large hole and lining it with a polyethylene mat, which was later replaced by a rubber liner and ultimately a spray-on concrete finish. This evolution reflects Thornton’s commitment to improving and expanding his dream pool over the years.

Measuring approximately 95 feet across at its widest points, Thornton’s pool is a sprawling aquatic wonderland. The pool features a sandy shallow area created with 18 pickup loads of sand and a deep end that allows for high dives and flips. One of the pool’s standout features is a captivating waterfall where visitors can sit behind, look through, or let the water cascade onto them, adding to the natural, scenic beauty of the setting.

Innovative Filtration System

Thornton’s ingenuity shines in his custom-designed filtration system. He consulted with pool builders but ultimately decided to devise his own system. The filtration system includes a massive underground pit filled with well strainer casing and sand, allowing gravity to push water through slowly, resulting in clean, filtered water. Thornton’s innovative approach ensures the pool remains pristine despite its enormous size.

Overcoming Challenges

Building a 500,000-gallon pool came with significant challenges. One of the most daunting was filling the pool, which takes three months of continuous pumping from a well Thornton dug specifically for this purpose. The well produces about seven to eight gallons of water per minute, highlighting the immense scale of the project and the logistical hurdles Thornton had to overcome.

A Labor of Love

Thornton’s backyard pool is more than just a personal achievement; it’s a labor of love shared with family and friends. His wife, Jane, contributed to the pool’s aesthetic by handling the horticulture and insisting on its strategic placement away from the house. The pool has become a communal space, hosting events ranging from birthday parties to weddings, and even baptisms, with over 400 people baptized in its waters.

Financial Investment

The financial investment in such a massive project is substantial. Thornton estimates that maintaining the pool costs about $200 a month in electricity and involves using 100 pounds of chlorine tablets each week. Despite the ongoing costs, Thornton’s passion for his pool remains unwavering, as he continues to invest time and resources into maintaining and enhancing it.

Community and Family Enjoyment
