The City of Roswell recently released its latest Water Quality Report highlighting the status of the water produced by the city’s water system. You can read the full report to learn the details. (Suggestion: You may want to go to the last page of the report first to look over the definitions, which will help you better understand the rest of the report.)

Here are some further insights related to Roswell’s water supply and its delivery system to get it to the citizens:

The city’s water production is overseen by Central Control. The city has 30 wells – 20 are production wells and 10 are irrigation wells – scattered through the south end of town. The production wells feed the city’s water supply while the irrigation wells are leased to farmers. However, irrigation wells also serve as backup in case they need to be added to the production system to maintain the city’s water supply.

 The wells feed water into the distribution system to customers, as well as into the city’s six storage reservoirs. The wells and reservoirs are coordinated to work together to meet the demand of customers. The six reservoirs together can hold 24 million gallons of water.

 At each well site, the water is disinfected with chlorine gas before heading into the city water system. Water Production Supervisor Jesus Talamantes oversees the water system and ensures the water is disinfected properly. Wells are checked twice each week, with workers making sure the disinfecting chlorine levels are appropriate and that the wells’ production levels are properly regulated to the water demand in the city. In addition, the area surrounding each well – known as the “area of influence” – is maintained regularly in order to prevent contaminants from seeping into the water as it is being produced by the well.


Water is tested monthly to ensure it remains safe. Samples are taken from a variety of locations at different points along the water system and tested so any excessive contaminant levels or unsafe substances can be detected and the situation rectified. In the Water Quality Report, you will see different dates on different sample results because state regulations differ as to the frequency of testing for different substances.


According to available records, Roswell has never had to issue a boil water advisory or had any serious health issue occur with the water supply.
