The Environmental Services Division hosts a free Environmental Matters Webinar Series twice a month. The webinars will cover a variety of topics related to water and the environment. For each webinar you attend before June, you will get one entry into a raffle for a FREE rain barrel (open to City of Superior residents only). To learn more and register for webinars and see the topic list, please visit www.ci.superior.wi.us/webinar. Each webinar lasts about a half hour. The webinars are being archived and can be watched anytime after their presentation.
