The reflecting pools at the September 11 Memorial in New York City have undergone a meticulous refurbishment process, ensuring they remain a symbol of reverence and reflection. The pools, which replaced the Twin Towers, were drained and cleaned, and new waterproofing materials were installed. Nightly maintenance includes filling the pools with fresh water and adjusting the water level to maintain the ‘never-ending’ waterfall effect. The pools are now clearer and more reflective than ever before.
