A splash pad or spray pool is a recreation area, often in a public park, for water play that has little or no standing water. This is said to eliminate the need for lifeguards or other supervision, as there is little risk of drowning. Typically the water is either freshwater, or recycled and treated water, that is typically treated to at least the same level of quality as swimming pool water standards. These splash pads are often surfaced in textured non-slip concrete or in crumb rubber.
