What is the Three Basin Rule and how does it impact wastewater treatment?

Sandy is subject to more wastewater regulations than almost any other City in Oregon. The Three Basin Rule - a state drinking water regulation originally adopted in the 1970s and last amended in the 1990s - permanently caps the volume of effluent that can be discharged in the Clackamas, Santiam, and McKenzie river basins.

Why are wastewater issues preventing the issue of new land use permits for development?

We are running up against the limit of how much treated wastewater the City can discharge, which is why the City is moving forward with this comprehensive approach. These discharge limits are determined by the Three Basin Rule. If we exceed that limit, we will be fined by the federal and state governments.  Under the federal Consent Decree, we are required to implement a permanent solution and are limited in issuing new land use permits for housing and businesses until we do.

Is the City trying to secure other funds to reduce the cost to ratepayers?

Yes. We have secured multiple state grant from the legislature, including $5 million in 2025.  We are working to have additional funds appropriated by the state. We’ve also been able to secure low-interest loans from the state and federal government, and continue to look for additional ways to lower the cost to ratepayers.

What will be the cost to ratepayers to update our wastewater systems?

We project that ratepayers will see significant increases on their wastewater charges, likely 10-14% per year for the next eight years. The overall cost of these projects is over $200 million. In 2025 we secured $5 million from the Oregon Legislature to support these projects, which will reduce the cost to ratepayers. We recognize that this will be hard for the community, particularly given other recent increases.

Why has the City not addressed this issue before now?

The City has taken a number of interim steps over the years, but this city council was willing to take on the task of finding a long-term solution. They recognize it is important to the future of Sandy to not kick this can further down the road.

What other options did the City consider before making this decision?

Options considered including doing nothing, upgrading the existing wastewater treatment plant, increasing irrigation of local nurseries, letting treated wastewater soak into the ground, temporarily storing untreated or treated wastewater, relocating discharge to Deep Creek, sending wastewater for treatment to another Clackamas County treatment plant, relocating discharge to the Sandy River, and sending wastewater for treatment to Gresham.

Why are you proposing switching wastewater services to the City of Gresham?

We need a comprehensive approach to meet our wastewater needs, both now and in the future. We are under a federal consent decree that requires us to implement a comprehensive solution, and to maintain a moratorium on new land use permits until we’ve done so. After an extensive and deliberative review of all options, we have concluded this is the best long-term solution for the City.
