Based on the newly developed concept of the rainwater utilization potentiality in urban area (RUPUA), RUPUA at the research site including the Beijing Olympic Park is estimated as 2,230,000 m3. Three measures were taken for increasing the rainwater utilization: sunken lawns, permeable bricks and water storage tanks. Their influences on the runoff change were discussed and different cases of rainwater utilization measures were researched. When all three measures were taken as designed, average annual rainwater utilization at the research site would be 414,000 m3, which is about 18.6% of the total potentiality.
