Harlequin Launches New GRP “Super-Subs” Range

 

Harlequin is pleased to announce the launch of our new GRP Super-Subs range, bringing together dependable wastewater treatment performance, durable GRP construction and a distinctive new look.

Designed to work where it matters most below ground the Super-Subs range has been developed to provide a reliable wastewater treatment solution for domestic and commercial applications.

Built to Perform Below the surface

Manufactured using strong and lightweight Glass Reinforced Plastic (GRP), the new range has been designed with durability, installation and long-term performance in mind.

Its slim-profile design makes the system particularly well suited to sites where space is limited, while still delivering the dependable treatment performance expected from Harlequin.

The range combines practical engineering with straightforward installation and maintenance, providing customers, installers and merchants with a solution they can rely on.

Quiet Performance. Serious Capability.

The Super-Subs may have a playful new identity, but there is serious engineering underneath.

Key features of the range include:

  • Durable GRP construction
  • Efficient wastewater treatment
  • Designed for straightforward installation and servicing

The result is a compact, dependable wastewater treatment solution designed to quietly get on with the job beneath the surface.

A New Look for Harlequin Wastewater

The launch also introduces a bold new visual identity for Harlequin’s GRP wastewater offering.

Inspired by the unmistakable shape of the tanks and their below-ground working environment, Super-Subs gives the range its own memorable personality while highlighting exactly what these products are designed to do deliver dependable performance underground.

It represents a fresh approach for Harlequin as we continue to develop our wastewater range and provide merchants, installers and homeowners with high-quality solutions backed by decades of manufacturing experience.
