Is it legal to dump potable water to a open ditch drainage?
if the water is potable in origin and no significant additions have occurred during usage or transit, there should be no issues with discharging it to a ditch. A discharge is defined by the Clean Water Act as the addition of any pollutant (including animal manure or contaminated waters) to navigable waters. Navigable waters are broadly defined as any surface water source, whether in man-made ditches or natural streams, that leave an owner’s property.
