HDPE CDS

The most efficient and durable hydrodynamic separator for storm sewers

Our CDS is also offered in HDPE! Same technology, same performance now offered in a single-piece structure 50% lighter than the heaviest component of a concrete treatment device.

  • Complete range offered from 910 mm to 3050 mm (36 in to 120 in) in diameter.
  • Simple installation; like an HDPE manhole, therefore similar to a traditional concrete manhole, but in one action only!
  • Single-piece, HDPE CDS doesn’t require any assembly on-site.
  • As they are made from HDPE, it provides excellent resistance to de-icing salts, abrasives, chemicals and vibration.
  • Soleno’s HDPE structures are designed to perfectly adapt to all types of pipes.
  • Designed to resist CL-625, H-25 and HS-25 loads.
  • Offered exclusively by Soleno in Quebec and the Atlantic Provinces.
Model shown: HDPE CDS-5 with two inlets
*Than the heaviest component of a concrete treatment device.

Advantages and Benefits

The 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.

  • 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.
  • Easy access for maintenance, no work in confined space.
  • A separate sump for sediment retention prevents the resuspension of sediments during peak flow events.

Why choose HDPE CDS?

Efficient Technology

The performance of the CDS lies in the unique configuration of its central separation cylinder. This one creates a vortex that forces the sediment to move towards the storage sump as the floating debris are held in the centre of the separation screen. The oils are retained by the oil baffle.

Thanks to its unique profile, the continuous deflection separation screen, made of stainless steel, prevents any risk of clogging and facilitates maintenance.

Because of its configuration, the separation screen modifies the path of debris by redirecting it into the vortex, in the centre of the system.

Single-piece in HDPE

HDPE structure offered in single-piece compared to a traditional concrete structure which can have more than 3 pieces!

  • Simplified installation; similar to a traditional concrete manhole, but in one action only!
  • All-in-one structure; no assembly required on-site.

Single-piece structure 50% lighter!

The complete HDPE structure is 50% lighter than the heaviest component of a concrete treatment device.

All-in-one Configuration

The CDS treatment system combines all the structures required in a traditional treatment system, by combining the functions of an inlet, a bypass structure and a junction unit into a single structure.

Applications

  • New treatment installation;
  • Replacement of traditional treatment system;
  • Pre-treatment for infiltration and bioretention;
  • Retention of sediment and debris upstream of watercourses;
  • Pump protection.

HDPE, a durable material

High-density polyethylene is an extremely durable, effective material with a lifespan that can exceed 100 years! In fact, it is the most ecological choice for mastering storm water. HDPE is resistant to corrosion, abrasion, de-icing salts and vibration, ensuring long infrastructure life. This material is a much better choice than concrete, thanks to its cost and low environmental footprint.

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.
* General Use Level Designation

Operation

Steps

    1. Runoff and storm water enter the CDS through the main sewer lines or through the CDS surface grate.
    2. Sediments, floating debris and oils are directed to the central separation cylinder.
    3. The vortex created by the movement of the water forces the sediment to move towards the storage sump, where it will be retained.
    4. Floating debris are held in the centre of the separation screen; its unique design redirects debris to the centre of the vortex, preventing long-term clogging. The oils are retained by the oil baffle.
    5. Water that is now free of sediment, oil and debris is discharged under the oil baffle and redirected to the outlet.
