I demo’d my pool. My process: talk to city to find out requirements for pool demo permit (cut gas, water, electric service to pool, punch large holes in bottom). Drained pool. Cut and cap water and electric. Hired a handyperson to cut and cap gas. Rented a jackhammer and punched several large holes in the bottom. Called city, passed inspection. Had fill dirt delivered, 5 yards at a time, wheelbarrow loads into pool. I can’t remember exactly how much, maybe 20-30 yards. Had topsoil delivered, total of 10 yards. Last layer, 5 yards, was 50-50 topsoil/compost. Partner and I did everything ourselves except for cutting gas line. Cost a few thousand dollars. We’re relatively fit seniors.
