We add several other chemicals to the water. Chlorine is added for disinfection to prevent disease. Ammonia is added to the finished water to combine with the chlorine to reduce the amount of free chlorine and to provide a longer combined disinfection residual. The City will perform testing of customers water for identified problems or concerns. We have a routine testing program in the distribution system to test for bacteria and chlorine residuals.
Daily testing is performed for a variety of other parameters.
Other chemical testing is performed quarterly and annually. Q. My water pressure has dropped off and seems to fluctuate. The water distribution system has various pressure zones. Your water pressure will normally vary only slightly within each zone. If you are seeing a drop or increase in your water pressure, there could be a problem in your building.
