Collecting Roof Run-Off

A system for collecting, controlling, and disposing of runoff water from non-residential farm buildings.

Description

Gutters, downspouts, and other water conveyance devices prevent roof runoff water from causing severe erosion or mixing with animal manure and transporting pollutants to waterways.

Benefits
  • Improves water quality.
  • Reduces soil erosion.
  • Increases infiltration.
  • Protects buildings and other structures.
Planning
  • Does runoff need to be diverted away from structures or contaminated areas?
  • Will the runoff be collected and used for other purposes?
Tech Notes
  • Contact our office for free guidance.
  • Runoff may empty into surface or underground outlets.
  • Outlets must not discharge near wells, septic system drain fields, basements, or buried tanks.
  • Discharge runoff a minimum of five feet from the building. The discharge area must slope away from the structure.
  • Avoid discharging outlets directly into surface waters.
  • When feasible, divert runoff onto pervious landscapes such as lawns, infiltration trenches, and natural areas.
Maintenance
  • Keep roof runoff systems clean and free of debris and obstructions that reduce flow.
  • Inspect regularly and perform repairs to ensure proper function.
