Orifice flow control is where an orifice plate helps control/restrict the flow of water into a sewer or sewage treatment management system.
At Cotterill Civils, we stock the ORIFLO Range of orifice plate flow control chambers. These are designed to support SuDS management and the sewer infrastructure as part of a designed attenuation system, helping prevent flooding by controlling the flow into the main sewer.
Oriflo flow control chambers are a highly affordable option to manage surface water flows on site, this can prevent flooding.
At Cotterill Civils we stock the ORIFLO 300 series, the ORIFLO 450 series, the ORIFLO 650 series and the ORIFLO 1050 series, which all have different purposes and can be versatile to meet your needs.
The ORIFLO 300 is specifically designed for pre-filtered surface water from small modular/crate attenuation systems and permeable surfaces.
The ORIFLO 500 Orifice Flow Control Chamber comes in two designs:
OFCP500 – This model is classed as an unprotected orifice chamber and is designed to be installed downstream of pre filtered surface water run off ie. permeable paving and cellular/crate attenuation systems.
OFCC500- This model is a protected orifice chamber and is designed to be installed downstream of tank and attenuation systems.It has a removable Silt Trap,which protects the orifice from silt and debris entering from the upstream pipework/storage.
The ORIFLO C SERIES is designed to be utilised in SuDS applications, where water is not pre-filtered. Typically downstream of medium to large attenuation systems.
