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.
