ROMOLD Discharge Chambers
Discharge chambers in the ROMOLD DN1000 or DN625 platform are a logical solution for pressure sewer discharge into gravity lines.
This is where the liberation of hydrogen sulfide gas, caused by long residence times, can be the most disruptive. Receiving the sewer into a full plastic manhole chamber solution negates this corrosion risk, and also prevents any scouring that may occur in a concrete manhole. The chamber can be ventilated to a Green Dome filter at this point.
ROMOLD discharge manholes are constructed to meet project specifications and offer a number of solutions dependent on Council preferences.
