Flood and drought conditions due to the global crisis occurred in Bayat District, Klaten Regency. This is due to the rural characteristics of the area, where land has been converted from forest to agricultural land and settlements. This condition causes rainwater cannot infiltrate into the ground, thereby increasing runoff and reducing groundwater reserves. Therefore, the concept of Water Sensitive Urban Design (WSUD) is applied to this location to reduce the risk of water disasters. One of the WSUD technologies that can be applied is the permeable paving block system. This system can help infiltrate water to the ground thereby reducing runoff that causes flooding and storing water to replenish groundwater reserves. The design is planned in the pilot area of Jotangan and Krikilan Villages, Bayat District by applying a partial exfiltration pavement system. The structural design of the pavement layers is in the form of a permeable paving block with a compressive strength of 21.29 MPa with a thickness of 10 cm, a bedding layer of 6 cm, an open-graded base of 18 cm, and a drain pipe with a capacity of 3,78 mm/hour. The permeable paving block system in the WSUD pilot area can reduce runoff by 62.64%.
