According to said method, in a first step the water (1) is subjected to preliminary mechanical purification in at least one mechanical purification device (5, 8) and in a second step is subjected to biological purification in at least one biological purification device (12, 13). The water (1) is transported by gravity during and between the purification steps and the purified water (1) is optionally returned to the swimming pool (4).
