Since 1425 AH, Prince Sultan Institute for Environmental, Water, and Desert Research at King Saud University has pioneered two techniques for harvesting and storing rainwater and floodwater. One involves drilling wells for groundwater recharge, the other entails constructing industrial cisterns. The institute has validated the efficacy of these methods through meticulous implementation and evaluation of their outcomes. The first method was executed in 22 dam basins in Riyadh, Qassim, Hail, and Madinah regions, the second was used in the governorates of Dhurma and Ushairat Sudair. These approaches have significantly increased groundwater reserves, elevated water levels in nearby farm wells, improved water quality, and mitigated the risk of floods. The institute also conducted scientific studies in the field, together with government agencies, including one aimed at reducing the risk of floods in Riyadh City, and one that identified prime locations for implementing developed methods in Wadi Lith and Wadi Fat imah, which were subsequently endorsed by the Makkah Region Development Authority. According to the institute, similar studies will be conducted with government agencies and royal reserves. Source: Saudi Press Agency
