The value of the assets of a city water and sewer system will most often amount to millions of dollars. Maintaining those assets will cost the city substantial monies in the annual budget. But proper maintenance will actually result in significant long-term savings. Maintenance extends the life of equipment, lines, pumps, etc., putting off costly replacements. Also, poor maintenance usually results in more operational problems. This often will cost the city in overtime pay or even having to contract outside workers to make repairs and restore service. Employees should follow regular maintenance schedules and make necessary repairs as needed.
