Sanitary Sewer Overflow Due to Vandalism, Warning Signs Still Posted

Due to vandalism, sewage has overflowed directly into Mill Creek and into the Columbia River. The sewer pipe has been cleared and the pipe has been repaired. No more sewage is overflowing.

Out of an abundance of caution, signs have been placed at locations of public river access on the Oregon shore of the Columbia River, from The Dalles Riverfront Park to West Mayer Park boat launch. The signs say: “Warning - Contaminated Water - No water contact” and give phone numbers to call for information.  These signs will remain in place at least until Thursday September 29, 2022 to allow time for water quality testing. Read the full press release here.

Water Distribution

Hydrant Flushing Picture

Routine Flushing of Fire Hydrants

Water mains are flushed annually in order to:

  • Clean out deposits, sediments and rust from our distribution pipelines;
  • Minimize water quality problems;
  • Test fire protection water pressures;
  • Exercise hydrant valves; and
  • Identify hydrants that need to be repaired or replaced.

Motorists and pedestrians are asked to avoid driving or walking through the water coming directly from a hydrant while the main is being flushed. If it is not possible to avoid the area, please proceed with caution.

The Water Distribution Division manages the operation and maintenance of a complex water distribution system consisting of transmission mains, water booster stations, pressure regulators, storage reservoirs, and groundwater sources. Premium water quality is maintain through the efforts of water system sampling, water quality, complaint investigation, backflow protection and needed system upgrades.
