FACTS: The City has adequate capacity to support current and planned future development.
- The reservoir has an estimated current capacity of 1,100 acre feet which is 358 million gallons
- The Water Treatment Plant (WTP) capacity is 8.5 million gallons per day (MGD) and currently is producing 2 MGD to meet the needs of the City
- The WTP has room for additional expansion
- The highest demand for water during summer months has been 5 MGD
RUMOR: Is the City pumping raw sewage into Rickreall Creek?
FACTS: Sewer overflows can occur when rainwater or groundwater enters the underground pipes that carry sewage to the treatment plant. The extra water can cause the pipes to overflow at the treatment plant, and result in the release of untreated sewage into the environment. Sewer overflows are quite common in the Willamette Valley, due to the winter rainfall. However, sewer overflows at the City of Dallas Wastewater Treatment Plant are rare and, when they occur, generally last only a fraction of a day. The City has been working to address sanitary sewer overflows by replacing older, leaking underground pipes, and removing direct connections where rainwater enters the sewer system. Over the last 3 years, the City has invested more than $1.5 million in projects to address rainwater or groundwater entering the system. System overflows during the last 5 calendar years are shown below:
|Year||Number||Description of Overflow(s)|
|2014||1||March 8 for 5 minutes (equipment malfunction)|
|2015||4||December 7 and December 18 due to a continuous storm*|
|2016||1||November 24 & 25 for 24.5 hours|
|2017||3||January 1 for 17 hours, February 5 for 15 hours, and February 9 for 14 hours|
*The overflows in 2015 occured during the storm cycle which resulted in a federally declared disaster in the state of Oregon
This winter, the Willamette Valley has experienced extreme rainfall. As a result, sewer overflows are above our average of about 1 per year. The City has experienced 4 overflows over the last 4 months due to the abnormal precipitation. When overflows occur, the City follows our State and Federal permitting requirements and protocols. One of the requirements is to post signage downstream of the treatment plant. As a precaution, the signage always stays in place for several days - much longer than the duration of the overflow. For further questions, please contact the City at 503.831.3562.
