If you have ONWASA sewer, the sewer portion of your bill can be adjusted one time per year according to the size of your pool. However, the water portion of your bill can not be reimbursed since that is water used.
Backflow is used to describe a condition that occurs when a difference in water pressure causes contaminants to enter the municipal water distribution system and/or the customer’s water piping. The two most common kinds of backflow conditions are backpressure, where a device such as a pump forces higher pressure water and contaminates into the distribution system against the existing system pressure, and back siphoning, where a suddenloss of system pressure (due to a water main break or heavy demand) causescontaminates to be drawn into the distribution system. Backflow prevention assemblies are designedto sense these conditions and react to prevent contamination.
ONWASA has adopted rules and regulations, based upon State and Federal laws, that require the installation of backflow prevention assemblies at locations that have been identified as having potential hazards to the public water distribution system should a backflow condition occur. This includes all commercial properties and residential properties meeting certain criteria identified in Article VI of the ONWASA Utility Ordinance. Backflow assemblies are also required to be tested annually by a Certified Tester to ensure they function and continually protect the public water system. A link to Article IV may be found below.
These markings mean a utility locate request has been called in for construction work that will be done on or near your property. Blue lines and flags indicate there is a buried water main or service in that area, while green lines and flags indicated buried sewer lines. Any time someone needs to make an excavation, they are required by the State’s NC811 law to make a request for all buried utilities to be located and marked prior to the performing the work. Requests may be made by calling 811, entering the information at the NC811 website or with their downloadable mobile application. This is a free service. Additional information on NC811 regulations and contacts for companies that perform locates on private lines may be found at NC811.org.
What does this mean? This is not an emergency as total coliform bacteria are generally not harmful themselves. Coliforms are bacteria which are naturally present in the environment and are used as an indicator that other potentially-harmful bacteria may be present. Coliforms were found in more samples than allowed and this was a warning of potential problems. Usually, coliforms are a sign that there could be a problem with the treatment or distribution system (pipes). Whenever we detect coliform bacteria in any sample, we do follow-up testing to see if other bacteria of greater concern, such as fecal coliform or E. coli, are present. We did not find any of these bacteria in our subsequent testing. However, we advise customers to boil water used for human consumption until we have determined that the coliform bacteria are no longer present in the system. After we have determined that coliform bacteria are no longer present we will rescind the boil water advisory.
We also rely on you the customer to report any water quality issues you may experience at your home. For a full list of water quality sampling ONWASA conducts please view EPA’s Drinking Water Watch.
If you are concerned about a particular regulated contaminant being in your home, there are independent laboratories that will analyze your water and ONWASA will be happy to provide you with those contact numbers.
