FVB Case Study – Meridian Water DHN

 

  • Project Timeline: 2020 – Ongoing
  • Location: Enfield, London
  • Client: Proven Project Construction

The Meridian Water DHN project is one of the largest District Heat Network (DHN) schemes in the UK with a planned total length of approximately 20km that will supply heat to residential homes and businesses in the London Brough of Edmonton.

The scheme is operated by Energetik, an energy supply company (ESCo) established by Enfield Council, with a view to the ongoing expansion of the system to provide affordable low carbon heating and hot water supplies.

The DHN in the main utilises highly insulated (series 3) pre-insulated pipes, with the spine pipework installed in DN400 (700mm Outside diameter) size pipe. A challenging design proposition through highly congested urban roads and infrastructure.

FVB have been engaged to undertake DHN system sizing verification which has involved the hydraulic review of the proposed system, confirming lines sizes based on the confirmed and estimated connecting loads and a number of operational scenarios that were agreed with Energetik.

FVB have also been engaged to undertake the design of the main district heating distribution network in Zones A1 and B1 coupled with the provision of Principal Designer services for these work elements. FVB’s initial contract works will span 2022 & 2023 with further expansion of the network expected beyond this.

As part of the design works FVB have provided for-construction design services for the buried network, above ground sections of pipe, river and culvert crossing design and major road crossings including structural assessments, reports and designs.

Additional to the technical design, FVB have been contracted to provide the Principal Designer role ensuring that the clients responsibilities are discharged in line with the CDM 2015 regulations.

FVB works include:

  • Review of heat loads,
  • Heat network line sizing validation,
  • Review and design of pumping requirements,
  • Pumping station positioning,
  • Design of heat delivery network including river crossings,
  • Design of major road crossings,
  • 3D scanning of existing structures,
  • 3D pipework design,
  • Hydraulic modelling, review and optimisation,
  • Future connection design for extension of the DHN,
  • Principal Designer duties.
