Concrete CDS

The most efficient and compact hydrodynamic separator for storm sewers

The concrete CDS continuous deflection hydrodynamic separator is exceptionally efficient. It effectively controls and treats over 60%* of suspended solids, oils and floating debris from runoff water before discharge to an outlet.

Easy access for maintenance, no work in confined space (1).
O-ring gasket into the walls of the system make it easy to connect all types of pipes: HDPE, PVC and concrete (2).
A separate sump for sediment retention prevents the resuspension of sediments during peak flow events (3).
Complete range offered from 900 mm to 3600 mm (36 in to 144 in) in diameter.
Simple installation, similar to a traditional concrete manhole.
Designed to resist CL-625, H-25 and HS-25 loads.
Offered exclusively by Soleno in Quebec and the Atlantic Provinces.

New! Our CDS is also offered in HDPE. Discover now!

Advantages and Benefits

Designed for specific treatment rates, CDS provides customized solutions for each project.
For the same flow rate, CDS is the most compact option on the market, in diameter and height.
It saves money by reducing the footprint, unit size and excavation requirements.
It effectively removes 100% of floating and neutrally buoyant debris over 2.4 mm in diameter and recovers oil.
It provides a large storage capacity for oil, debris and sediment, reducing the frequency of maintenance.

Applications

New treatment installation;
Redesign or modernization of an existing structure into a treatment structure;
Replacement of traditional treatment system;
Pre-treatment for infiltration and bioretention;
Retention of sediment and debris upstream of watercourses;
Pump protection.

A High-performance Product

That exceeds environmental requirements

Canada’s Environmental Technology Verification (ETV) program provides independent assessment of new technologies by providing assurance to sewer system owners and managers that environmental performance claims are valid, credible and supported by test data. This program provides a clear assessment of the environmental potential and value of the submitted technology.

The performance of the CDS hydrodynamic separator has been verified by the ETV Canada program and approved by Quebec’s MELCC.

Proven and Approved

The best performing hydrodynamic storm water treatment system, based on MELCC evaluation criteria.
CDS is also approved by the Washington State Department of Ecology (GULD* certification level) and the New Jersey Department of Environmental Protection (NJDEP).
Tested in various environments; in the laboratory and at dierent sites, this system has proven itself for over 20 years.
