Why the Work Mattered

Purpose and Operating Need

The channel could carry the design flow, but debris accumulation created a practical failure mode; removable screens preserved maintenance access.

Engineering Approach

Engineering Approach

Specification scope: 304/316 stainless screens, 0.25-0.5 in openings, 12-gauge screen material, 34-degree tilt, bracket mounting to concrete tank pad side wall and drainage channel far wall, slotted guide rails, lift-out handles, optional hinged/latch design, 1/4 in stainless brackets, 1/2 in stainless anchors, 3-in minimum embedment, 1 in x 1 in x 1/8 in stainless angle frame, 3/8 in rods/cross-bracing, 1/4 in stainless edge bar, quick-release pins/bolt locks, and optional neoprene/vibration pads.

Measures & Operating Detail

Engineering scope and design basis

Designed removable screening to improve maintainability, reduce debris carryover, protect the step-down weir from clogging, and reduce long-term stormwater-maintenance burden.

Specified 304/316 stainless screens, 0.25-0.5 in openings, 12-gauge screen material, 34-degree tilt, bracket mounting to concrete tank pad side wall and drainage channel far wall, slotted guide rails, lift-out handles, optional hinged/latch design, 1/4 in stainless brackets, 1/2 in stainless anchors, 3-in minimum embedment, 1 in x 1 in x 1/8 in stainless angle frame, 3/8 in rods/cross-bracing, 1/4 in stainless edge bar, quick-release pins/bolt locks, and optional neoprene/vibration pads.

Designed measures to reduce drainage clogging risk, using removable 304/316 stainless screens, 34-degree tilt, 0.25-0.5 in openings, and bracket-mounted attachment to the tank pad and channel wall, by designing removable debris screening into the channel.

34-degree tilt; 0.25-0.5 in openings; 12-gauge stainless; bracket-mounted removable design.

Project ownership and delivery context

Owned the full project lifecycle: capital planning and prioritization, need definition, feasibility and scope development, engineering and AFE justification, procurement and vendor coordination, construction sequencing and field oversight, commissioning, turnover, and post-startup support. Connected operating requirements with technical scope, funding decisions, execution readiness, and the needs of operations and maintenance.

Developed the reinforced channel, debris screens, five-step weir, outlet basin and stabilization scope. Curbing, grading, landscaping and wastewater-collection interfaces were coordinated with the work. The system reduced sediment carry by more than 90 percent while providing a maintainable runoff path.
