Why are people still power washing on-campus?
Scheduled washing of buildings, parking structures, and hard surface areas ensures that rain water does not carry contaminants to the storm drain and exit to our oceans.We use high-pressure washing when dry methods of cleaning will remove hard surface debris such as oil, mold, and other pollutants. When high-pressure washing is necessary, we use low-flow high-pressure equipment. Because it is illegal for any of the water to exit down the storm drain, we block all appropriate drains. Water that does not evaporate is captured and either reused or diverted to campus foliage or an appropriate sanitation drain.(Learn more about UCSD Storm Water Management Program and Sewer System Management Plan.
