Frozen water is 9% lighter than regular water. That is the reason ice floats.
Owners, developers or general contractors are responsible for stormwater management on their construction sites. Stormwater runoff is rain or snow melt that cannot be absorbed by the soil and instead washes off the surface of the land. As stormwater flows over a construction site, it picks up pollutants that may be transported into nearby receiving waters such as rivers or the harbor.
To avoid this pollution, a construction site may need to obtain permits from federal, state and local authorities. Boston Water and Sewer Commission (BWSC) has prepared a helpful brochure to determine what permits and from which authority you will need. The brochure also contains compliance tips for your planning and preparation, a check list for permit application and several reference websites and telephone numbers. Visit our Doing Business page and search for Permits to find Stormwater Permits at Construction Sites.
Remember, dumping any material into the storm drains is illegal with fines up to $5,000 per day of violation. If you observe someone dumping into a storm drain, report it immediately to BWSC at 617-989-7000.
If you see a storm drain that is clogged with debris, report it to BWSC for cleaning (617-989-7000).
