Springfield Technical Community College (STCC) will offer an online course this fall to prepare students for careers in the drinking-water industry and to help those working in the field enhance their skills. The course, called “Concepts & Practices of Drinking Water Distribution,” is being offered through the Workforce Development Center at STCC in partnership with the Massachusetts Water Works Assoc. and the Springfield Water & Sewer Commission. The training, which runs from Sept. 14 to Dec. 4, is free for students enrolled in any community college in Massachusetts. Individuals not enrolled at a community college, as well as employees at water utilities, can register for the class for a fee.
