The City of Hays Water Resources Department has contracted with Pro-Pipe to conduct sewer line cleaning and inspections at the locations shown on the attached map. Cleaning will begin Wednesday, August 21, 2019. Pro-Pipe should be completed with the entire project on Friday, November 1, 2019.Door hanger notices will be placed on homes and businesses affected prior to cleaning.See attached map for detailed locations.Work will begin at the North end of the project area and proceed South until completedDuring this process, residents may experience a rumbling sound, in addition to the possibility of water entering your sink, bathtub and/or toilet. Sewer lines can develop air pressure or a partial vacuum from the cleaning process. Usually any excess air pressure or vacuum will dissipate through the plumbing vents, but occasionally there are facilities with inadequate plumbing vents (i.e.: no vents, undersized vents or obstructed vents). In this case of inadequate venting, air pressure could escape through the toilet, floor, sink, tub or shower drains, causing water to splash out or a vacuum could draw the water out of the fixture traps allowing unpleasant odors.If you will not be home or on vacation during the time of sewer line cleaning, please protect your home by keeping your toilet lids down.The City of Hays apologizes for any inconvenience this may impose. Performing this preventative maintenance by cleaning the sanitary sewer will improve the sewer's performance and significantly reduce the chance for future sewer backups and related problems.Should you have any questions or concerns, please feel free to contact Pro-Pipe’s project manager at 909-568-7070 or the Water Resources Department at 785-628-7380 or via email email@example.com.
