City Seeking Volunteers for FREE Plumbing Upgrades 
Beginning in April 2016, the City has developed a new approach to managing and communicating with residents and developers.  The City will maintain a master list of all residents interested in water use efficiency upgrades, including toilets, shower heads and faucet aerators. If you volunteer to be part of the program, you may be eligible to have your old, inefficient water fixtures replaced with new, high efficiency fixtures.  The developer or his contractor will determine if your home is eligible, pull a building permit and perform the work at no cost to you.  This will likely reduce your water bill and water use, while providing the needed offset for the developer.  Click HERE for program application form and instructions.
