NO-DIG Live 2021

East of England Arena & Events Centre, Tuesday 14th September – Thursday 16th September 2021.

No-Dig Live is free to attend and a must for anyone within the installation or refurbishment of underground utilities.

No-Dig Live offers exhibitors the opportunity to showcase products and equipment in a live working environment and is the only forum in the UK where manufacturers and suppliers can display and demonstrate products at an event that is focussed entirely on trenchless technology.

Conference Programme

Innovation Panel – This 2 hour session is an exciting opportunity for a handful of very select and appropriate ‘new’ initiatives and innovations to be presented to the panel of representatives from the UK utility companies. This forum is designed to solve the problems and needs the utility companies have with the solutions and innovations of our members as well as No-Dig Live exhibitors and the whole of the underground infrastructure industry.
OnSite Central are following the session with a pavilion and catered lunch, for networking between the innovative companies who presented and the utility companies who formed the panel.

Mini-Masterclass – Pipe Jacking & Micro tunnelling
A half day event for visitors to hear from experts in the field of the Pipe Jacking & Micro Tunnelling Sector presenting an overview of design criteria, machine choice and site based case studies.


1st European NODIG Conference
This inaugural one-day conference will be a high-level technical conference focused on the topic Rehabilitation Design for Pressure and Gravity Pipes. Each session will be opened with a Keynote paper from a leading industry expert.
The morning session will cover presentations specific to Gravity Sewer Rehabilitation with presentations on gravity sewer liner design methods in UK, France and Germany, a pressure testing case study and control and verification of in large diameter UV CIPP liners. The afternoon session will focus on Pressure Pipe Rehabilitation with presentations on international Standards, key design considerations for pressure pipe liners using HDPE and CIPP and a case study of a water main lining project. DELEGATE REGISTRATION IS NOW OPEN

Lunch time workshop – Structural calculation of Liners according to DWA-A 143-2
The DWA Method applies to the static calculation of liners and installation methods with any cross-section. The revision and transformation into a generally accepted engineering rule became necessary in particular due to the concept of partial safety factors for the actions (loads) and resistances, which was introduced with EuroCode 1. Another reason was the new regulation for heavy goods traffic applicable to bridge construction.

The presentation shows the basic procedure for the structural analysis of liners according to worksheet A143-2 of the German DWA. Among others, the following are addressed
– Pipe soil system
– Host pipe conditions (HPC)
– Host pipe condition I: The host pipe is able to bear the load alone. In this case, the liner only has to ensure sewer tightness.
– Host pipe condition II: The host pipe alone is not able to bear the load and has longitudinal cracks at four points on its circumference.
– Host pipe condition III: This host pipe condition corresponds to host pipe condition II with the crucial difference that the stability of the host pipe-soil system is no longer verifiable. In this case, the liner has to bear not only groundwater loads, but must at least partially help to cope with all influences, such as soil, traffic and superimposed loads.
– Host pipe condition IIIa (informative only): host pipe deteriorated beyond host pipe condition III, fragmented and not able to transmit forces in joints. Liner must be designed as a new installed pipe taking special consideration in account.
– Load models and their superposition
– Partial safety concept
– Approval: Stresses, deformations, soil limit stress, stability, inner pressure, uplift, dynamic proof and if time permits, a live calculation example will be presented.


Drilling Contractors Association (DCA)
The DCA is a technical association of the horizontal directional drilling (HDD) industry in Europe. The HDD method has established itself worldwide as a technical and economic alternative for the underlaying of obstacles in the field of pipeline laying. During No-Dig live Scott Stone will deliver a presentation focussing on the DCA as an organisation & will include some high level case studies which will give a greater understanding as to what is possible with the application of HDD ..

The Green Alliance – Working together to achieve net zero
On Thursday 16th September the Green Alliance will hold their first face to face seminar which will provide a series of presentations that address the challenge posed by climate change and the impact it is having on our environment and will include updates on the presentations that have been hosted virtually throughout the year. The Green Alliance was formed by The Pipeline Industries Guild and UKSTT to explore, share and promote the industry’s drive towards net zero and reduction in environmental impact.
