One thing often misunderstood in drainage pipeline bedding design, is the wide range of bedding options available for specifiers. Without proper guidance and assessment of available options, the likelihood of missing out on the most cost-effective ones is always high. Structural design of pipeline installations involves dealing with three main types of load: The weight… Read more »

The new British standard for concrete pipes, BS 5911-1, offers further type testing requirements and cement mix options to improve pipe performance in a world shaped by fatbergs, Net Zero Carbon, and infrastructures durability challenges. The British Standards Institute (BSI) published a new revision of BS 5911-1:2021, the concrete pipes specification standard, earlier this month…. Read more »

Our jetting tests: How significant are the findings

Jetting_Tests_II

In late 2019, BPDA carried out a number of high-pressure water jetting tests for a wide range of gravity pipe brands available in the UK market, including both concrete and lightweight plastic pipes. In this blog, we explore how significant are the findings from these tests and what do the results tell us about both concrete pipes and… Read more »

Tip of the iceberg #6: What about HDPE pipes made of recycled HDPE?

Posted by & filed under Construction.

In September 2020, the BPDA published a new report which demonstrated why the carbon footprint of concrete pipeline products is significantly lower than HDPE alternatives. However, that study did not look at HDPE pipes made of recycled HDPE. In this very lengthy blog, we raise questions about the likely carbon footprint of pipes made of… Read more »

Tip of the iceberg #5: The importance of the “functional equivalence” concept in Whole-life carbon assessments

In September 2020, the BPDA published a new report which demonstrated why the carbon footprint of concrete pipeline products is significantly lower than HDPE alternatives. In this blog, we explain the importance of functional equivalence and why a carbon assessment of drainage pipelines should include the pipe and its surrounding bedding, not only the pipe.   What is… Read more »

Tip of the iceberg #4: The carbon emissions associated with End- of-Life and the decommissioning of pipeline systems

In September 2020, the BPDA published a new report which demonstrated why the carbon footprint of concrete pipeline products is significantly lower than HDPE alternatives. In this blog, we explore how the End-of-Life and decommissioning stage (also known as Module C) can make a significant impact and why any infrastructure asset assessment will need to look at that stage… Read more »

Tip of the iceberg #3: Why Design Life (ESL/ RSL) is a big issue in Life Cycle Assessment and carbon footprinting?

In September 2020, the BPDA published a new report which demonstrates why the carbon footprint of concrete pipeline products is significantly lower than HDPE alternatives. In this blog, we explain why the service life of construction products is such an important element in carbon footprint assessments and comparison studies. We also demonstrate how it has… Read more »

In September 2020, the BPDA published a new report which demonstrates why the carbon footprint of concrete pipeline products is significantly lower than HDPE alternatives. In this blog, we explore one of the main findings of this report: The impact of HDPE resin origins. We explain why it is important to get the supply chain… Read more »

Tip of the iceberg #1: Study reveals a plastic pipe carbon footprint significantly higher than originally thought

Posted by & filed under Construction.

In 2018, the British Precast Drainage Association (BPDA) sought the services of Circular Ecology, the consultancy behind the ICE carbon footprinting database, to help them quantify the true whole-life carbon emissions associated with concrete and plastic pipeline systems. What Circular Ecology came up with (see report here) did not only help BPDA plans to improve… Read more »
