INNOVATIVE ACCESS CHAMBER FOR WASTER AND STORM WATER NETWORKS

“We see these manholes and the connections

as a solution to the ingress problems we are

currently experiencing.

“Anthony Clough [owner of ORCCA] has been

most accommodating in his assistance with our

unique problems on the Coromandel. I would

have no hesitation in recommending his service

or the products.”

Viv Eyberg, Capex Programme Manager,

Thames Coromandel District Council‘The chamber may be used as a terminal point

for gravity sections in either network and as a

non man-entry chamber at the end of a ramped

riser or extended connection where two dwelling

sites are to be connected to the principal line.’

Rodney District Council

“Water Engineering Consultants would be

delighted to discuss benefits of the ORCCA

manhole with any of your future clients.

We look forward to installing many more ORCCA

manholes.”

Benefits of an ORCCA

MADE OF POLYPROPYLENE: A strong, well

proven and durable material for a long service

life. Standard AS/NZS 5065 allows the use of

polypropylene pipes and fittings for drainage and

sewerage applications.

• VERSATILE: Applications range from using

as an access chamber in private properties to

stormwater quality treatment in rain gardens.

• LIGHTWEIGHT: ORCCA can be carried by a

person and installed by two persons easily and

quickly. This is particularly useful to minimise

inconvenience to residents in retrofitting situations

in private properties where access is difficult.

• SAFE: ORCCA ensures safety of operators

against confined spaces, as it does not require

man-entry for maintenance.

• EASY TO INSTALL: One person can easily

install an ORCCA, ensuring the required quality. A

second person is necessary primarily to meet the

OSH requirements relating to excavations.

• EASY TO MAINTAIN: ORCCA’s sloping base

does not allow sludge build up and high self-

cleaning flow velocities keep the outlet pipe clear

of blockages, requiring virtually no maintenance.

• ACCESSIBLE FOR CCTV / HYDROJETTING 88˚ rubber ring PVC bend joins up to PE or PVC pipes

on the main line

Only a ‘Y’ junction is needed to connect to the line. This eliminates the need for many different fittings

as the ‘Y’ can be rotated to achieve the desired 2% grade.

The Vortex effect results in self cleansing

and high flow rates
