Measuring rainfall provides BWSC with important data used in monitoring the efficiency of our sewer and drain systems during storm conditions. We use this information to evaluate the capacity of our infrastructure and plan proactive maintenance projects. This data can assist in monitoring stormwater runoff into Boston Harbor and the Charles, Neponset and Mystic Rivers.
BWSC maintains solar powered rain gauges on top of public buildings throughout the city. These gauges log measurements of precipitation and report data every five minutes. BWSC provides this information and uploads this rainfall data on a regular basis. BWSC reports rainfall data as far back as 1999, depending on the year of installation for the various gauges.
