Tennessee man built 500,000-gallon backyard pool over decades

Micky Thornton of Covington, Tennessee, began building a large pool in his backyard in 1993, and over nearly three decades transformed it into a 500,000-gallon water playground.

Thornton initially envisioned a spacious swimming area different from typical rectangular pools, drawing on a childhood idea. He and his wife, Jane Thornton, collaborated on the pool’s design, deciding to build it across their pasture land rather than next to their house. The project wasn’t completed quickly.

Thornton gradually expanded and improved the pool, adding features like waterfalls and rock decorations over the years. He used 320 yards of gunite and 40,000 pounds of steel rebar to create a durable and expansive structure. Because the pool’s size exceeded standard residential designs, Thornton designed and built his own filtration system to keep the water clean. Over time, the Thornton’s pool became a gathering place for the community. They initially let people swim for free, but later accepted donations.

The pool hosted a variety of events, including parties, weddings, baptisms, and even a visit from the Japanese National baseball team. More than 400 people from different churches have been baptised in the pool, which Rev. Keith King called “a huge blessing to others.” Thornton’s long-term project demonstrates that ambitious goals can be achieved through dedication and perseverance.
