May 09, 2019

The City of Crestwood Council approved the purchase by Louisville MSD of the City of Crestwood’s sewer system at their meeting on May 1, 2019. MSD already operated and maintained the Crestwood sewer system. This agreement simply moves the ownership of the system to MSD. Crestwood residents will no longer pay the Crestwood debt surcharge—resulting in a lower bill—and will benefit from being a part MSD’s larger system that can provide economies of scale, access to greater resources, more employees to respond to issues, and a dedicated customer service call center.

Bowl Patrol

MSD’s “Bowl Patrol” campaign offers a light-hearted approach to the issue of what to and what not to flush (hint: only “the three Ps” = pee, poo and toilet paper). Though the campaign uses humor to convey its message, the ramification of split-second bathroom decisions plays out in large—and frequently expensive—ways for Louisville MSD.
