Featured Video: Safe Drinking Water Act Anniversary

As December draws to a close, let's take a moment to commemorate the passing of the Safe Drinking Water Act 42 years ago, in December of 1974. For the fortieth anniversary, the Minnesota Department of Health released this video. The reminiscences on this landmark legislation include interview excerpts with former Vice President Walter Mondale (a Minnesota native) who was part of the Senate that passed the bill.

As we get ready to begin a new year, it's worth remembering how much public water utilities have accomplished in their vital work protecting public health. Though they may sometimes feel invisible, your efforts help protect the health and well-being of the people in your communities. Whatever else this past year might have brought you, that is certainly a reason to celebrate this New Year's Eve.

Featured Video: Will It Flush?

With the holidays coming up, a lot of your customers may be getting particularly creative with their flushing activities. After all, for a lot of us the holidays mean a lot of hectic activity and a house full of guests. When the house is full, the trash is full, and the bathroom's getting worked overtime, sometimes standards can relax a bit. And who can blame them? A lot of products do say "flushable," right there on the label.

If you think your customers could use some extra information on how several commonly-flushed products actually behave once they're out of sight, this video might help. In it, Pre-Treatment Technician Tracy Stevens from the City of Spokane Department of Wastewater Management uses a jar test setup to demonstrate the dangers to sewers and wastewater pumps posed by facial tissues, flushable wipes, dental floss, Q-Tips, feminine hygiene products, and flushable kitty litter. If you need to give someone a refresher on the flushable, this video could be a great place to start.
