Warr Acres ratifies emergency repairs after major interceptor collapse; council OKs broad contracting authority

WARR ACRES — The City Council on Dec. 18 ratified emergency declarations and reapproved emergency contracting after contractors' CCTV footage showed severe structural failure in a main sanitary interceptor running between manholes in Ward 1.

City staff and the contractor reported that "the roof of the pipe is completely eroded away," a finding that led staff to rule out trenchless fixes such as slip-lining and pipe bursting. "If it's that bad for half the pipe, we're pretty much assuming that it's that bad for the rest of the pipe," the project lead told the council during a detailed briefing on repair options.

After evaluating alternatives, staff recommended an open-cut repair replacing the line manhole-to-manhole for roughly 140–160 feet (staff estimated about 150 feet) and upsizing to a 27-inch pipe so the city would not need to re-open the trench later. Council voted to reapprove the emergency action the city took earlier in December, giving the city manager and staff authority to proceed within budget limits and subject to further cost detail.

Contractors warned the council that specialized materials and equipment are limited. One contractor said some key expanders and heads for pneumatic/static bursting would take months to source, and that pipe diameters in the 27–28 inch range are uncommon. Staff said work is unlikely to begin before Jan. 6 because many trade suppliers and crews are on holiday, but the contractor estimated about one to two weeks of on-site work once mobilized and materials are in place.

Council members pressed staff to ask the Oklahoma Water Resources Board (OWRB) whether existing loan funds earmarked for that corridor could be applied to this emergency repair and whether using loan proceeds would require full competitive bidding. The city attorney advised that an emergency declaration provides procurement flexibility but that budget limits remain controlling; a special meeting was proposed if the repair estimate exceeds available budget.

The council also instructed staff to expand public safety protections at the site (additional barricades and pump bypass plans) and to coordinate homeowner notices; staff confirmed homeowners adjacent to the failed section have been notified. The council directed staff to provide a detailed cost estimate and funding plan before construction begins.

Next steps: staff will attempt to secure materials and confirm OWRB eligibility, return cost estimates to council (or call a special meeting if needed), and proceed with the repair under the ratified emergency authority.
