Lake Oswego City Council Special Meeting: Approval of Emergency Water Main Repair Contract - August 26, 2026
Lake Oswego City Council Special Meeting: Approval of Emergency Water Main Repair Contract - August 26, 2026
The Lake Oswego City Council held a special meeting on August 26, 2026, to consider approval of a contract for emergency repairs following a water main failure on Del Prado Street. Public Works Director Eric Caruni and Assistant City Engineer Arush Navani presented an overview of the incident and the proposed work.
Presentation on Water Main Break and Repairs
- Incident Summary: On the night of Friday, August 21 (approximately 11 PM), a 12-inch cast iron water main installed in 1971 failed on Del Prado Street. The break released several thousand gallons of water per minute. Crews from Public Works, Fire, and Police responded immediately. The pipe was shut down and a temporary repair completed by 7 AM Saturday, with service restored by 1 PM Saturday after flushing, disinfection, and bacteriological testing. A boil water notice was issued for the affected area and lifted Sunday at 2 PM.
- Damage and Cleanup: The water flow damaged pavement along Del Prado and carried debris (soil, gravel, vegetation) onto nearby streets. Public works crews cleaned approximately three-quarters of a mile of roadway and removed about 25 cubic yards of debris from stormwater facilities. Geotechnical engineers assessed the base material. A temporary 10-foot section of ductile iron pipe was installed to restore service.
- Permanent Repair Plan: The city plans to construct a new 600-foot ductile iron pipe and abandon the old cast iron pipe. This approach was chosen because the road already needed reconstruction and replacing the pipe will provide another 60-70 years of useful life. The contract with Torney Excavation is on a time-and-material (force account) basis, consistent with Oregon wage rates.
- Budget and Schedule: The council was asked to authorize up to $1 million, though staff estimate the final cost will be less. Work is targeted for completion by October 15, 2026, barring supply chain issues.
- Infrastructure Context: The city has 122.2 miles of water lines, of which 57% (70 miles) is cast iron. A risk-based Capital Improvement Plan prioritizes replacement of high-consequence pipes (e.g., larger mains, those under major roads). This 12-inch main had high potential consequences, justifying the expedited replacement.
- Public Alert System: This was the first use of the county’s public alert system for a utility notice. The city learned lessons about geographic targeting; follow-up meetings with the county are planned. Approximately 50% of residents receive utility bills electronically, and reminders to sign up for alerts will be included in bills and at the upcoming disaster preparedness fair.
- Property Damage: Staff acknowledged possible property damage and stated that any claims will be handled through the city’s insurance process.
Key Outcomes
- Motion and Vote: Councillor Winland moved to adopt Resolution 26-5-1 approving the contract, seconded by Councillor Verdict. The motion passed unanimously (6-0). Councillor Afkin was excused.
- Council Praise: Multiple council members commended the rapid response, clear communication, and professionalism of staff across departments (Public Works, Fire, Police, GIS, Legal, and City Manager’s office).
Meeting Transcript
Okay, this uh good afternoon. This Thursday, August 27th, 2026 uh meeting of the Lake Osego City Council is now called to order. Ms. Hawkins, please call the role. Air Buck. Here. Councillors Wenlin. Here. Verdict. Here. Corrigan. Here. Edmund Smans. Here. Counselor Afkin is excused. And Councilor Mabu. Yeah. Thank you very much. Well, we've called this special meeting just for one purpose, and that is to consider the approval of a contract to handle the repairs on the recent Del Prado Street water main failure. We have our public works uh director and city uh engineer Eric Caruni here and assistant city engineer Arush Navani, and we appreciate you being here to talk to us about uh the contract. Great. Thank you, Council and Mayor, for taking the time out of your summer evening to have this meeting because it is critical for us in order to keep moving on this project. Um we really appreciate your time this evening. We'll try to keep it brief, but we thought we'd also give you an update a little bit about what happened, kind of a recap of that and and where we're headed in the next several weeks. Um before I do that, though, uh I just do want to say it's going well, if something like this can. It is actually going really well with our uh collaborative approach with all of our different teams out at maintenance with our engineering team and our inspectors all stepping up and making this the priority of the week for the public works department, and it's gone well, and I'm very proud of the accomplishments we've made and the collaboration that we're uh going to have, hopefully, with this with this contractor. With that, I'll turn it over to Mort, who's going to give us um a brief overview of the situation. Thank you, Erica. Uh thank you, Mayor and the counselors. I would also like to thank you for making this a special meeting on a short notice. I would also like to thank the city manager's office and our legal team because they work magic that we were able to uh get this meeting together and the contract thereafter in less than 48 hours. So, with that, I would like to share with you uh what we are facing with and what we are doing and what we have done so far. And so the event at uh last Friday night around um 11 o'clock. Uh we had a 12-inch uh cast iron pipe in Del Prado Street uh failed. And the pipe was installed back in 1971 to give you a little bit of uh the context of the age of the facility that failed. And then immediately our public works and the fire department and the police department responded uh to the emergency and our public works crews uh shut down a 12-inch main. Uh, just to give you a little bit of an idea, it's not an easy task to shut down the 12-inch main that has over 100 PSI of pressure in it. So it's not like uh sort of a kitchen faucet, if you will. Yeah, we were losing you know several thousand gallons of water a minute. So that takes some time. Um and then once we secured the site, we contacted the tourney um excavation uh contractors, and they responded immediately in the middle of the night, and we were able to actually complete the repair by seven o'clock in the morning. Except there are several other steps you have to take after the pipe is sick. You have to flush the line, you have to disinfect it, you have to test it. Uh so the service came online around one o'clock Saturday afternoon. It's still extremely responsive and quick. Uh, because of the amount of water we have lost, and some limited areas have lost basic pressure. It's it's uh normal standard or procedure that you issue a limited boil water notice until you repressurize the system and also take the necessary test, which is basically bacteriological testing. That we did that immediately, and then we could leave the boil water Sunday afternoon at two o'clock. Just to give you an idea, the impacted area is Del Prado, and the break was right around here, but the force of water actually have damaged significantly all the pavement along the way, if you will. And I have some pictures I'll show with you to see what water can do.
