Springfield hears plan to extend metro wastewater service to Creswell and Goshen; engineers flag local constraints and funding questions

Lane County and regional wastewater officials on Tuesday asked the Springfield City Council to support advancing a metro plan amendment that would let the Eugene–Springfield Metropolitan Wastewater Management Commission (MWMC) accept sewer flows from Creswell, Goshen and the Short Mountain Landfill.

Dan Hurley of Lane County Public Works and MWMC and consulting staff outlined alternatives and preliminary costs for the multi-jurisdictional project. They said a new local treatment plant would cost roughly $70 million, while connecting the communities into the existing metro system would be in the $40 million–$45 million range. Staff also discussed a proposed additional financing component of about $12 million to be taken on by Creswell or Lane County to support the connection; together those figures place the connection option near $52 million in cited planning estimates. (Transcript contains a garbled single-line figure that staff clarified in presentation as the $40–45M plus $12M components.)

Consultants and MWMC staff said the regional plant appears to have capacity to absorb most of the new flows over a 20-year buildout, but they flagged local constraints that require further engineering: the Glenwood pump station and McVay/McVeigh trunk lines could need upgrades to convey Creswell/Goshen flows to the plant. MWMC Executive Director Matt Statter said the plant has "available capacity in excess" at the system scale but acknowledged localized needs where costs and who pays must be worked out.

Presenters emphasized operational and environmental benefits if the landfill’s leachate—about 25 million gallons a year, staff said—could be directly piped rather than trucked on Highway 99. Vincent Marielo and consultant Catherine Geese described that hauling leachate by truck can require dozens of truck trips during wet weather and creates carbon and safety costs that a pipeline could eliminate.

Councilors repeatedly pressed who would pay for needed upgrades in Springfield’s local lines and whether existing ratepayers would be protected. Staff said the proposed cost-recovery approach relies on MWMC’s system development charge (SDC) methodology, which charges new users for a share of past and future capacity; staff also proposed a 5% ongoing out-of-network surcharge on new flows so existing ratepayers would not shoulder added operating costs.

Councilor questions focused on timing and disruption: a full engineering design and detailed capacity analysis remain to be done; the earliest major construction needs—for example, a fourth pump at Glenwood—could be years away depending on buildout. Staff described a multi-step process that would include a joint planning commission review, public hearings among affected jurisdictions, and intergovernmental agreement amendments before any final council action.

Mayor and several councilors expressed general support for continuing the policy conversation while insisting that agreements protect Springfield ratepayers and define who pays for localized upgrades. Lane County and Creswell staff said Creswell faces a state mandate and is actively pursuing a financing plan; staff asked councils to indicate policy support to proceed to planning and technical work.

Next steps: staff will present further engineering and financial analyses in coming months and pursue the Metro plan amendment and interagency agreements; no formal vote was taken at this meeting.
