Advances in production techniques for precast manholes offer multiple advantages for the construction sector. Innovations championed by BPDA members mean manhole installation can be completed in about an hour, with a much higher success rate when compared with traditional techniques. Precast manhole systems are easier to install, but they also improve onsite safety and raise… Read more »

A report into Sweden’s water and wastewater networks anticipates a long-life for the next generation of pipes. The authors of Sustainable water and wastewater pipe systems of the future, which has been published by the Swedish Water & Wastewater Association (SWWA), argue that the networks currently being installed should have an operational life of at… Read more »

What is the maximum jetting pressure acceptable for concrete pipes?

Posted by & filed under Pipes & Manholes.

In the UK, high pressure water jetting is widely used to clean and mostly to clear blocked sewer pipelines – often as an emergency operation. The European Standard BS EN14654-1:2014 Management and control of operational activities in drain and sewer systems outside buildings, Part1: Cleaning, states that “Maximum safe working pressures to avoid damage will… Read more »

What is the minimum depth of cover needed for concrete pipes?

Posted by & filed under Pipes & Manholes.

concrete drainage

Minimum cover depths for concrete pipes vary depending on the vehicular traffic loading likely to be sustained by the pipeline. There are various industry specifications and Standards that state values for minimum cover depths based on these loading conditions. Most loading conditions used for design either relate to patterns of wheel loading generated from main… Read more »

Advice for specifying precast concrete manholes

Posted by & filed under Pipes & Manholes.

concrete manhole

When inspection or maintenance of buried wastewater drainage systems is required a manhole is specified. They are most often built at the point where one pipeline connects to another, where a pipeline changes size, direction or gradient and at a spacing that enables equipment to be used effectively. Here we detail some advice for specifying… Read more »

Effective Drainage for Poor Ground Conditions

In any construction project, bad ground conditions can create a wide range of problems and can even bring construction to a halt. This is why when Peter Harding Construction began work at St Wilfreds Academy in Blackburn, they knew they needed a drainage solution. The solution had to combat the poor ground conditions, not hinder… Read more »
