Title 124 - NEBRASKA DEPARTMENT OF ENVIRONMENTAL QUALITY
Chapter 19 - Floor Drains
001 A floor drain in a dwelling garage may be connected to an onsite wastewater treatment system provided the drain does not receive oil, paint, engine cleaner or hazardous materials and meets design requirements of Section 002. These drains are designed to handle snow and ice melt along with occasional exterior vehicle washing.
002 A floor drain in a dwelling garage that is connected to an onsite wastewater treatment shall meet the following design requirements:
002.01 The drain shall have an integral mud trap and oil separator.
002.02 A valve shall be located immediately following the drain that shall normally be left closed.
003 The design capacity of the onsite wastewater treatment system shall be increased at least 75 gallons to account for a dwelling garage floor drain connection to the system.
004 It is recommended, but not required, that a permanent sign or plate be placed on or within view of the drain stating "WARNING - Water Only! Floor drain leads to an on-site system". This sign is intended to remind current and future owners that the garage drain leads to an on-site wastewater treatment system that cannot properly treat some types of wastes.
005 The discharge of motor vehicle wastes or maintenance shop wastes to a septic system or to a soil absorption system is prohibited. The connection of a floor drain from a maintenance shop to a septic system or soil absorption system is prohibited.
