Wastewater Project

Wastewater Homeowner's Manual

Congratulations Coburg!  The Wastewater Project is nearing completion! The Wastewater Treatment Plant has been online since July 2013. All street connections are complete. The final phase contractor is substantially complete and has made all tank connections.  The final landscaping and system testing continues through summer.

Wastewater Project Costs

What are the Project costs and why is it expensive?  There are many different funding sources contributing to this Project including: Federal loans and grants; State loans and grants; an Urban Renewal Distruct; a Local Improvement District; and User Fees.  This financial structure has been in place prior to the beginning of the project. 

Coburg was the second to last City in Oregon to be off septic systems.  It is a small community and wastewater tratment system that meets current Federal and State regulations is expensive when less than 500 sites comprise the initial system. 

The Project has remained largley within budget since construction began in 2010.  However, in this final hook-up phase (connecting businesses and houses), there have been some cost over-runs.  The main reason is that more existing septic systems have 'failed' than anticipated.  The Project has tried to use any existing tank that meets the current requirements.  However, far more sites had unmaintained/leaking/unpumped and/or illegally placed tanks than the engineers estimated.  This means that more failing tanks needs to be decommissioned (secured) and new tanks needed to be installed which is costing the City more time and resources.  It has also cost more disruption to the citizens' yards.  The positive is that Coburg property owners are no longer responsible for maintaining thier septic tanks.  The City will maintain the systems from now on; significantly reducing the ground contamination and decreasing the current threat of groundwater pollution. 

Direct Costs: User Fees and Local Improvement District Assessments

The direct cost to property owners for this project interim construction user fee is $65 per month/EDU.  The first billing cycle following the month that a property is successfully 'hooked-up' to the new wastewater system is the month that the wastewater user fee becomes $85 per month/EDU.  As long as the project remains on time and on budget, this will be the final user rate for a number of years.  See Fact Sheet - Cost Calculator below.

The Local Improvement District is a one time assessment on each property which will be assessed at the end of the Project.

The City has hosted multiple Open Houses during the planning and implmentation of this Project.  The most recent Open House was held May 23, 2013, 4:30-7:00p at Coburg City Hall View details (PDF).

The next Open House to discuss the Local Improvement District assessment will be held in July- tentatively - be held in July 2014.

For Developers

Wastewater Systems Development Charges (SDCs) were approved in 2013.  Wastewater SDCs have been added to the existing Water, Transportation, and Parks SDCs for new development (e.g. new houses).  

The System

Coburg is one of the largest and last Oregon cities that does not have a municipal sewer system. With a daytime influx of 3,000 employees in various commercial and industrial facilities and over 200 RV visitor spaces in town,  you will understand why replacing the the town's septic tanks with a wastewater collection and treatment system is Coburg's highest priority.

To accomplish this, the City has chosen to install a Septic Tank Effluent Pump (STEP) system to collect the the wastewater and send it to a treatment plant through pressurized lines. At the plant, a Membrane Bio-reactor (MBR) system will treat the wastewater before it is released back into the environment. This system will result in Class A effluent, the highest level water quality possible in the Oregon Department of Environmental Quality's (DEQ) rating system. Much of this effluent will be used for irrigation.

Coburg's system is modeled after an existing system in Yelm, Washington, a town of about 10,000 population. For more information, click on the links below.
