Virginia City leaders press for short- and long-term fixes after wastewater bypasses and basement flooding

Paul Christiansen, an operator with PeopleService, told the Virginia City Council’s Committee of the Whole on July 1 that recent rain events produced flows far beyond normal levels at the city’s wastewater plant and that emergency bypasses had been used to protect public health.

“We opened the bypass at 03:20AM on Saturday, June 21,” Paul Christiansen said, describing operator action during the June 20–21 storm. He told the council that normal daily flows are about 800,000–900,000 gallons per day but that flows spiked to about 10,000,000 gallons per day during the June 17 storm and to about 8,000,000 gallons per day on June 21. Christiansen said the plant can handle roughly 3,000 gallons per minute through its treatment process but that the influent pumps and other limiting factors mean operators sometimes must bypass the plant to prevent sewage backing into basements.

Why it matters: councilors and residents said hundreds of homes experienced basement flooding and sewage backups after the storms, and several speakers urged quicker short-term protections while the city pursues longer-term engineering fixes and funding.

Christiansen described the mechanics and limits: the plant has about 3,000,000 gallons of on-site retention and an influent flow meter that reads up to roughly 12,000 gallons per minute before becoming submerged and losing an accurate reading. He also described the bypass device as a roughly 40-inch pipe whose valve requires about 100 turns to open and “takes about 15 minutes to open.” He said operators must notify the Minnesota duty officer and collect bypass samples when bypasses occur. “Property human health has to come first before environmental compliance,” Christiansen said.

Public works director Jim Rosvid told the council the city’s collection system, not PeopleService, makes the call to open bypasses; operators at the plant carry out the physical operation and sampling. Rosvid said the city’s lift stations and aging pumps add operational constraints and that recent inspections show many pumps and casings are old and in need of replacement. He confirmed the city stages and uses portable pumps and that staff are working around the clock during high-flow events. Rosvid said the city has three large portable pumps available (two diesel, one gasoline) and that adding more pumps would be expensive.

Councilors pressed for actionable steps. Councilor Pam Paulson moved — and Councilor Motley supported — a motion directing staff to contact regulatory agencies about the potential to increase sanitary sewer outflow capacity and the distance of the outfall. That motion passed. Council later approved a separate motion authorizing the public works director to stage pumps and take operational actions to mitigate flooding; that motion passed on a 6–1 roll call.

City engineer Matt Reed and PeopleService offered immediate and longer-term ideas at the meeting: additional bypass or relief pumps placed further out in the collection system; targeted retention (holding) basins or ponds like those used in nearby communities; expanded smoke testing and targeted I/I (inflow and infiltration) investigations; homeowner education about sump pump discharge and check valves; and a team-based plan combining city staff, the engineer of record, and PeopleService to develop a prioritized capital plan.

Not all details were resolved at the meeting. Councilors asked for clearer records about whether a plant bypass occurred on June 17; Christiansen said the plant did not bypass on the 17th and that a bypass was opened at 03:20 a.m. on June 21, while members of public works and some councilors reported differing recollections. Christiansen said flow meters and SCADA trends provide detailed time-series data and agreed to share those records with city staff and the engineer of record.

What happens next: Council directed staff to assemble a pathway for action — combining operations, prioritized repairs, and funding options — and to pursue regulatory and permitting conversations. Christiansen and PeopleService told the council they will work with city staff and the engineer of record to provide data and technical input for that pathway. Residents who suffered damage asked the council to seek immediate, demonstrable relief while longer-term projects are funded and scheduled.

Ending: Council members stressed the issue combines aging infrastructure, extreme rainfall, and private-property drainage issues. Staff and councilors said they will return with more detailed recommendations, cost estimates and permitting guidance so the council can weigh short-term emergency measures against longer-term capital investments.
