One of the main challenges Water Distribution faces is the maintenance and replacement of cast iron water pipes used in the 1930's and later years to establish the City's water system. Cast iron can deteriorate which causes breaks in the supply system. Through comprehensive research and compiled leak history that goes back over 10 years, the department replaces the old lines with pipes made of modern PVC.
Another area the department is responsible for keeping in good working order is water valves. If a valve is not working properly when there is a water break the water main can not be isolated and repairs made in a timely fashion.
