Drainage & Water Management Products – PBM October edition, 2021

From the pages of PBM’s October edition, we take a look at the latest drainage & water management products.

Webinar series
ACO Water Management is undertaking a series of webinars and podcasts discussing the ways in which the construction industry can better protect the UK’s biodiversity and wild habitats, reflecting the impact of climate change and following on from the IPCC’s recent landmark report.

Accordingly, ACO’s Habitat Matters series is exploring the proactive steps the construction industry can take to create an environmentally sustainable future. Collaborating with 60 partners and supporters, the campaign brings together a number of industry leaders, government representatives, and partner organisations to highlight how the construction industry can help integrate habitat preservation into the built and urban environments.

The series includes eight webinars and six podcasts, which started in late August and continue to the end of October in advance of COP26 in Glasgow. The first in the series, ‘Future Cities Encompassing Natural Systems’, looked at how biodiversity action plans & biodiversity net gains can affect planning, how sustainable drainage systems (SUDS) play a vital role in urban environments and how building retrofit can help and benefit nature.


Brett Martin
Pictured following its use in the redevelopment of the former Mission Hall, a listed Victorian building in the Bradmore Conservation Area of Hammersmith in West London, the authentic detailing of Brett Martin’s Cascade cast iron-style rainwater system was deemed to be an integral part of the restoration. Neil Davies Architects and its client specified a Cast Iron Style Hopper in the Gothic design in Porcelain White to bring period authenticity to the distinctive façade, whilst a 105mm Round Downpipe in Porcelain White was also installed to match the white painted cement render.

In addition to Porcelain White, Cascade is available in a choice of eight heritage colours including Classic Black, Anthracite Grey, Oxford Blue, Chartwell Green, Olive Green, Graphite Grey and Sandstone. The complete range delivers the traditional appearance of cast iron with the convenience of modern plastic materials whilst Cascade is also UV stabilised to ensure “a maintenance-free system that will stay looking great and working well for years”.


BPF Pipes Group
Plastic Inspection Chambers Guidance
With advancements in sewer inspection technology, including more compact cameras and inspection units, there is an ever-decreasing need for manholes to be installed. Above-ground working is now the default, with below-ground working and access to manholes limited to specific situations (for example deep installations and intersections of multiple property drains).

Accordingly, in Water UK/OFWAT’s Code for Adoption, Annex C Design and Construction Guidance (Version 2.1 May 2021), inspection chambers are recommended for many points of access to the public sewerage network.

The BPF Pipes Group is strongly committed to the provision of clear and consistent technical information which is easily accessible to developers and designers. It has published a new guide which summarises where, what and how many access points are required for the construction of drains and sewers across all parts of the UK.


Hunter Plastics
Extended colour offering
Reflecting broader design trends, Hunter Plastics has extended the colour offering of its rainwater systems to include over 150 RAL colours in a range of matt and textured finishes. From post-box red and deep teal to bright pink and sunshine yellow, the new colours are available on the 112mm Half Round, Surefit 125 and 114mm Squareflo rainwater systems — all manufactured to meet British Standards.

The bespoke colour service is easy to access, with customers simply required to note the RAL reference of their desired colour, and include this when placing the order through their normal route.


Described as the original linear floor drain and the invention that helped create Unidrain, the ClassicLine featured patented wall and floor flanges which enable the drain to be positioned against the wall yet keeping the surfaces 100% waterproof. First introduced in 2003, the series has expanded and now includes six different options in brushed stainless steel — the Column, Stripe, Anniversario, Classic, Square and Inca, each with their own stylish grating design.
