Welcome to the Spring / Summer 2016 issue of Pipelines, your eNewsletter from the Concrete Pipeline Systems Association.
Concrete has been a high performance, long-lasting material of choice for drainage engineers for over 150 years. Its durability is not in question but the benefits of a strong, heavy and rigid material in use can be overlooked. Our newly-launched Heavyweight Champion of the Drainage World campaign aims to remind you of the specific attributes of concrete that contribute to world class drainage systems. In this issue of Pipelines we outline the arguments behind our Heavyweight campaign, offer you the opportunity to participate in our competition and highlight recent innovations that enhance the use of concrete drainage in modern construction sites. I hope you find the issue enlightening.

Concrete, Heavyweight Drainage Champion
Modern drainage asks a lot of its materials. You need a system that’s totally reliable, easy to install, cost-effective, sustainable and compliant with all the relevant standards. It’s no job for a lightweight. That’s why concrete is still the UK’s best choice for sewerage systems. Concrete offers strong, stable, sustainable performance backed by over 150 years of proven success. Download our Concrete Heavyweight Champion brochure to see the arguments.

Awards recognition for Innovations from the concrete pipeline sector
Innovations championed by the Concrete Pipeline Systems Association have been shortlisted in two categories of the Ground Engineering Awards, being presented on 30 June. The Concrete Pipe Lifter, designed to make offloading and installation safer and faster, is a finalist in the Health and Safety category, plus the Circular Precast Manhole Base System, designed to use less concrete than a formed in-situ solution whilst saving time and money during construction, is shortlisted in the Sustainability category. Welcome recognition for some serious innovation.
Choosing concrete : twenty reasons why
In case any reminder is necessary, CPSA has published a guide: 20 reasons to use concrete. Ranging from cost efficiency to watertightness the brochure considers how the inherent characteristics of the material contribute to stable, long-lasting high performance. It’s an excellent summary of the reasons that concrete continues to make a make a major contribution to drainage systems around the world. Download here
High pressure resilience to blockage removal
High pressure water jetting is a common practice to clear blockages in drains and sewers and to help maintain hydraulic efficiency of the system. It is not an uncontroversial practice as the high pressures required can damage some pipeline materials. A CPSA factsheet looks at jetting pressures set out in the Sewer Jetting Code of Practice, together with the standards required by various water authorities and considers how different pipe materials are likely to cope with the pressure.

Concrete pipes and reduced imported bedding – a cost effective combination
An effective underground pipeline system consists of the pipe in combination with backfill and embedment material and its interaction with the surrounding soil. The choice of bedding material will depend both upon the ground conditions and the pipe material. Concrete, being a rigid material with inherent strength, often allows for a greater range of bedding design choices, with the potential to introduce significant cost savings. The CPSA factsheet on bedding choice outlines the technical considerations around the choice of pipeline and bedding material. Download here or refer blog post here
Inertia and its importance for buried sewer infrastructure
Heavyweight concrete provides lots of inertia, without which buried pipes and other drainage infrastructure can be more easily dislodged from their intended position, both during and after installation. Jointing force during installation and compaction of bedding material around a pipe can potentially destabilize its position, while a high water table or an episode of flooding can displace lightweight pipes with low inertia. Our blog post explains
Limiting deformation essential for quality pipelines
It is vitally important that users understand the differences between flexible pipes such as plastic and rigid pipes such as concrete and to appreciate how these materials perform in terms of structural integrity and hydraulic efficiency. Our recent blog post directs readers to recent research and case studies on the impact of using a flexible pipe material on the integrity of the installed system.
Heavyweight Champion – the headlines explained
Concrete pipeline systems have been part of the backbone to the UK’s sewerage network for over 150 years for good reason. The inherent strength of precast concrete products, their durability and their availability in a wide choice of sizes and cross-sectional shapes has made them a favourite choice. Our recent blog adds some of the detail behind the headlines in our Heavyweight campaign.
