PUBLIC NOTICE: City of Seaside Annual Water Main Flushing Program

The City of Seaside Water Department will begin its annual water main flushing program over the next two months (October and November). During this time period you may experience turbid or "redish" color water. This may include a slight alteration to taste and a mild odor may be present.

The water is safe for consumption and should clear up after running your taps for a few minutes (usually three to seven minutes). If the condition continues, please notify Seaside Public Works at (503) 738-5112.

The Seaside Water Department is a division of Seaside Public Works and operates 24 hours a day, 7 days per week, 365 days a year. The City of Seaside thanks all residents and businesses for their understanding during this annual maintenance program to keep the water system safe and effective.

As a City of Seaside water customer, you expect your drinking water to be completely safe.  The Seaside Water Department is committed to delivering you the highest quality and healthiest water possible.  To help assure these high standards the City has a cross connection control program, as required by EPA and the Oregon Department of Human Services (DHS).  The cross connection program requires the use, regular maintenance, and inspection of backflow devices which prevent back siphoning of water through irrigation or fire suppression devices.  Such back siphoning could introduce harmful substances into your household plumbing or public distribution main.  Protection is assured through a special backflow prevention valve.  If backflow occurs, water would run backwards through your pipes and into the drinking water system.  This could potentially introduce contaminants to the drinking water system.  Fortunately, you can help make certain this does not happen.

  • Irrigation Systems: Ensure an approved backflow assembly is installed, is in good working order, and tested annually.
  • Swimming Pools and Hot Tubs: Ensure that if a water hose is used to fill these units it is protected with a hose bib vacuum breaker installed on the faucet.
  • Residential Boilers: Ensure an approved backflow assembly is installed, is in good working order, and is tested annually.
  • Private Wells:  Ensure that wells are not connected to a public water system.

Oregon Administrative Rules; Chapter 333-61-070 requires public water suppliers to carry out cross connection control inspection programs, discontinuing water service to customers who fail to install an approved backflow assembly where a potential cross connection may exist.  The device must be tested and certified annually by a certified testing company and the certification is to be paid for by the home or business owner.  For assistance with backflow issues contact Seaside’s Water Department at 503-738-5112.


The main source for the City of Seaside’s drinking water is the south fork of the Necanicum River nestled in the west slope of the Coast Range between Sugarloaf Mountain and Kidder’s Butte.  The City’s water right on the south fork is for 8.0 cubic feet per second (CFS) or 5.2 million gallons per day (MGD).

During the summer, when demand is high and flows are low, the City augments its water supply from the main stem of the Necanicum at Peterson Point with a 7.0 CFS or 4.5 MGD water right.  The advantage to the south fork source is that water can be gravity fed to the 50 million gallon raw water reservoir.  Water must be pumped into the raw water reservoir from the main stem.

The distribution system in Seaside serves a permanent population of 6,100 people but must be capable of serving a much larger tourist-based population in the summer.  The piping system is comprised of 43.4 miles of water main of various materials from 2” to 24” in diameter.  

The City of Seaside has an average daily use of about 1.8 MGD and a highest day usage of about 3.3 MGD.  Every year the City publishes and distributes to its water customer a Water Quality Report or Consumer Confidence Report (CCR) for the year 2019 outlining the water quality and water quality issues for the year.
