Stormwater Drainage Hydraulic Calculations
Budget: $250 – $750 USD
I need a complete set of hydraulic calculations for a new stormwater drainage network whose primary objective is to improve water quality before discharge. The layout will rely on three key elements—culverts, storm sewers, and strategically located retention ponds—so every calculation must dovetail with those components.
What I expect from you is a clear, technically sound model that shows how each pipe, culvert, and pond will convey, detain, and treat runoff under various design storms. Please incorporate industry-standard methods (Manning, Rational, SCS, or similar) and any reputable software you normally use, then document all assumptions, equations, and safety factors directly in the report.
Once the numbers are final, translate them into concise tables summarizing peak flow rates, velocities, detention volumes, and required dimensions. A brief narrative explaining how the proposed system meets local water-quality criteria will round out the submission. If you work in CAD or GIS, feel free to include plan sheets or screenshots—anything that helps me plug the design straight into permitting.
When I can open your package, see the calculations reproduce correctly, and trace how each element achieves the targeted pollutant-reduction goals, the project will be considered complete.
