Draft:U.S. Patent 9,765,508 B2
Pool drain invention
From Wikipedia, the free encyclopedia
U.S. Patent No. 9,765,508 B2 is a United States utility patent granted in 2017 to inventor Stanley Greberis for a system designed to aerate and disperse wastewater and greywater above ground. The patented method describes an apparatus that disperses water across a landscape surface while exposing it to air prior to discharge. The system has been associated with residential water management applications including swimming-pool backwash and sump-pump discharge.[1]

The technology has been implemented in products such as the Eco Pool Drain Fountain, which has been referenced in industry coverage of pool and spa equipment.[2]
Background
The patented system originated from efforts to address residential wastewater disposal issues, particularly the release of chlorinated swimming-pool water and other non-potable household wastewater streams. Traditional disposal methods often route such water into storm drains, sanitary sewers, or subsurface dry wells. The patented design proposes an above-ground method intended to disperse water across landscaped surfaces.[2]
Patent description
The patent describes a surface-level wastewater aeration and dispersion apparatus. According to the patent description, the system receives wastewater from sources such as pool systems or sump pumps and releases the water through an outlet designed to disperse it across a landscape surface.
The method includes exposure of the water to air prior to discharge. The design aims to distribute water over a wider area rather than releasing it as a concentrated point discharge.
Applications
Uses associated with the patented method include:
- swimming-pool backwash and overflow discharge
- sump-pump water dispersion
- greywater distribution
- landscape irrigation using non-potable water sources
Products implementing the system have been marketed for residential water management and pool drainage applications.[1]
Recognition
The invention and related water reuse concept have been referenced in environmental recognition programs in New Jersey. The New Jersey Department of Environmental Protection announced Governor’s Environmental Excellence Award recipients associated with water conservation and environmental innovation.[3]
Environmental organizations have also referenced the inventor in connection with environmental award recognition related to water management initiatives.[4]
