Tuesday’s Water Wisdom 

 

Storm Lake Water Wisdom #35 brought to you this fine Tuesday from the City of Storm Lake involves Stormwater & Industrial Water Reuse. 

 

Water Wisdom continues the examination of ways to be water efficient by looking at two potential areas of water conservation. Stormwater reuse can be considered a subset of internal reuse in that it may occur within the confines of a single property, but it can also be accomplished on a larger scale beyond the boundaries of a single property. Industrial water reuse can be discussed in broad terms as any methods or means by which a commercial operation utilizes any previously used process water for another purpose which results in a net decrease in demand for potable water from the municipal source.   

The use of barrels to catch rain from rooftops for later use is the most basic of stormwater reuse methods and was covered in the June 14, 2021 installment of Water Wisdom. Stormwater reuse, however, can get much more elaborate and complex when applied on larger scales limited only by imagination and budget. One stormwater reuse practice that has been in use by the City of Storm Lake for several years but goes largely unnoticed is the use of permeable pavement and other water quality practices that capture a portion of the stormwater runoff, slow the flow, and allow the infiltration of stormwater into the ground for aquifer recharge. This is water that would otherwise have escaped as runoff. If a large volume of stormwater were to be captured from impervious streets, roofs, and parking lots and stored for later use, some level of treatment such as filtration or disinfection would be required as well as the infrastructure to move the water from the place of collection to the location of use which would inevitably add costs. Cost to benefit ratio analyses would need to be completed to determine where these practices would make sense to install.      

 

Industrial reuse could make a significant impact on potable water demand. A substantial percentage of daily potable water production is consumed by industrial customers so any changes these firms could incorporate to reuse water could potentially drive significant water demand reductions. The City of Storm Lake has been in conversations with local industries and all stakeholders involved in these talks understand the need to explore these possibilities to create green initiatives, economic development, and resilient systems. Future discussions and ongoing conversations will be necessary to determine what options could be implemented given the economic and regulatory considerations.

More tips regarding voluntary water conservations measures and tips for reducing water consumption will follow each Tuesday.  Ensuring wise use of our water resources is in the best interest of the community.  

 

Being Storm Lake Proud is not one day, one week, one month or one event.  Being Storm Lake Proud is a magnificent lifestyle!  More information about the City of Storm Lake can be found on the city’s website at www.stormlake.org.
