10/18/2018 – Testing, testing, 1, 2, 3

Play boulders and logs for the new splash park Membrane cassette testing using potable water

With most of the work on the exterior of the Clean Water Facility complete, crews are moving inside to start testing the facility’s new state-of-the-art equipment. Equipment throughout the plant is tested first with clean, also called potable, water. The membrane cassettes that will help remove microscopic solids from the flow coming into the facility are currently being tested.

Continuing work on splash park

Crews are continuing to work on the splash park, including work on the boulders and the area that will become the river feature. Want to know what they will look like? Check out the photo below of the future play rocks and logs that will serve as key features of the splash park.

Fun fact of the week

Potable water, like the water we use during testing, is water that is safe to drink or to use for food preparation. The word potable comes from the Latin word potare, meaning to drink. Here’s a tip to help during your travels, the word potable is the same in French. You’ll always know how to ask if water is safe to drink while you’re in Paris!
