Another Fast Assembly of a Rocla CDS® for Maroondah City Council

Thank you and congratulations Maroondah City Council on your choice of proven Rocla CDS® P2018 recently installed to protect the local Mullum Mullum creek in Ringwood, Victoria like no other GPT can.

The CDS® was safely, capably, and quickly assembled by Winslow Constructors with DN1800 Inlet and outlet pipes feeding treated water onto an energy-dissipating slab and into the creek.

With a heritage of the largest installed capacity of GPTs, Rocla partners with forward-thinking asset owners, consultants, and customers – like Maroondah Council, designers Engeny and Winslow – to develop Proven, Trusted, Durable, and Effective stormwater solutions.

With proven research and years of university testing, CDS® continues to lead the market as the original with no equal for proven effectiveness. Ask us – for sizing and complimentary industry-leading design at
