Client: JR Pridham Services Ltd
Location: Goshall, Stour Marshes, Kent, UK
Service division: Controls
Sector: Water

The Environment Agency (EA) are a public body whose aims are to protect and improve the environment. As part of this role, the EA are responsible for the operation of a number of pumping stations, one of which is Goshall pumping station, located in the Stour marshes in Kent. The EA have made a number of operational improvements at the pumping station, including the installation of a new remote monitoring station. As part of these upgrade works, the pumping station required a new control panel to be designed, built and installed on site.

JR Pridham Services are an EA approved contractor, offering a wide range of services that include electrical engineering, instrumentation and control. Pridhams were requested to design, build, install and commission the new pumping station control panel, the design and build component of which was subsequently awarded to AFECO to deliver on their behalf.

Due to space constraints on site the panel had to be built as two separate units, one housing the pump starter and the other housing the controls. The panels were designed, built and FAT tested to be fully compliant with the EA requirements and delivered within the allocated budget and timeframe.

The services provided by AFECO to this project included:

  • Design and build of two Form 4 panels in GRP
  • FAT testing
  • SAT testing
  • Documentation
  • CAD drawings (GA’s & schematics)

Basingstoke WwTW control panel

Client: JR Pridham Services Ltd
Location: Basingstoke WwTW, Basingstoke, Hampshire, UK
Service division: Controls
Sector: Water

Basingstoke WwTW is a sewage treatment works with a population equivalent of 100,000 and is owned and operated by Thames Water, the UK’s largest water and sewerage company, serving a population of 14 million across London and the Thames Valley. A number of process improvements have been made at the site by Thames Water, including the installation of a new sludge dewatering facility. As part of this process, the washwater system was upgraded and as a consequence a new washwater feed pump panel was required.

JR Pridham Services are a TW approved contractor, offering a wide range of services that include electrical engineering, instrumentation and control. Pridhams were requested to design, build, install and commission the washwater panel within a 6 week programme. AFECO had previously carried out a site investigation and prepared the project brief on behalf of the Client and due to the rapid turnaround required, AFECO were commissioned by Pridhams to undertake the project on their behalf, the scope of work for which included:

  • Design and build of a Form 4 panel in 316 stainless steel
  • FAT testing and documentation
  • Site installation and commissioning

The panel was designed, built and FAT tested to be fully compliant with Thames Water F15 Package Plant Specifications. The project was delivered successfully, within the specified timeframe and budget.

Food waste anaerobic digestion projects

Client: EcoGenR8 Ltd
Location: London, UK
Service division: Engineering
Sector: Waste; Water; Energy; Power

EcoGenR8 develops and manages waste treatment and renewable energy supplies in the UK with a primary focus on producing biogas through the anaerobic digestion of organic wastes. In 2011, EcoGenR8 were awarded a contract to develop a portfolio of energy from waste (food waste anaerobic digestion) projects with Thames Water, the UK’s largest water and sewerage company. Thames Water serve a population of 14 million across London and the Thames Valley including  an established network of over 30 anaerobic digestion sites.

Anaerobic digestion has been used to treat sewage sludge for many decades. As well as reducing pathogens in sludge, the process produces valuable biogas which is converted to electricity and heat through CHP (combined heat and power) engines, or upgraded to natural gas quality (biomethane) and injected directly into the gas grid.

EcoGenR8 partnered with Howard Tenens, a sustainable logistics company, to develop the Thames Water opportunity, the focus of which is to sweat existing assets and maximise synergies with current operations in order to develop a portfolio of sites that will have the capability to treat food waste and generate a combination of renewable electricity and biomethane. The project  incorporates detailed technical and commercial development, including:

  • Definition of the market potential
  • Development of technical and financial models
  • Identification of technology, waste, construction and operational partners
  • Planning and permitting applications
  • Securing contracts required for financing

AFECO are providing ongoing support to EcoGenR8 in developing the technical aspects of this project and in particular site investigations, technology evaluations and assessment of integration with existing assets.
