MANHOLE ODOR - PRESSURE RELIEF VALVE

Trapped air in sewer systems is one of the causes of flooding in public space. In case of a sudden surge of storm water, trapped air in the sewer system, creates overpressure in the sewer. After heavy rain a sewer could quickly overflow.

Westatlantic Tech Corp offers an effective mechanical check valve system that prevents odors from escaping the sewer system through a manhole cover, but allows pressure relief in the event the system becomes flooded during heavy rains.

The valves odor control does not depend on filters or chemical liners, rubber seals keep the system odor tight for normal operations and opens when the pressure increases from rising water in the pipe/manhole system.

The consequences of traped air may result in flooding of house connections, causing overflowed damage, Manhole covers could be dislodged from manholes, resulting in a hazardous situation in the roadway or sidewalks.

Even a complete manhole cover, including the surrounding pavement could be separated from a fast and increase in pressure. Manhole pressure and odor control valves installations help offer a a innovative and effective solution to the problem.

Manhole Odor control Valve and pressure relief valve fit most city manhole sizes

Mandole control valve operations:

Normal operation valve closed no odor escape

Bypass Valve allows water to enter drain system

 

Heavy Rain Sewers Running Full

If pressure builds Valve opens to release pressure in the system

Valve closes again when rain event is over - Odor control valve closed.
