Client: Damar Group
Location: Aberporth MOD Test Facility
Service division: Engineering
Sector: Water


Damar Group are a multi-disciplined service provider, delivering civil, mechanical and electrical engineering services. AFECO were engaged by Damar to provide support in the design and commissioning of a new fire fighting booster pumping station at Aberporth MOD test facility, a project that was being delivered through Kelda Water.

Kelda Water appointed Damar to design, build and commission the new fire fighting booster station to replace the old existing system that had been serving the MOD facility since the 1920’s. On behalf of Damar, AFECO oversaw the design and procurement of the booster set and assisted in the design of the Motor Control Centre (MCC) and control system, flow metering, surge protection and anti-vortexing plates.

The services provided by AFECO included:

  • Booster pump design
  • MCC design
  • Commissioning documentation
  • Commissioning management
  • Take-over testing

Bristol Water supply potable water to the region and Frome WTW treats reservoir water prior to distribution but has a historic problem of high nitrate levels entering the reservoir lines. Damar were appointed as Principal Contractor to implement a new nitrate reduction project to monitor the incoming nitrate levels and perform the right level of blending to reduce these levels to below the permitted maximum.

The services provided by AFECO included:

  • Commissioning management
  • Documentation preparation and control

Superyacht sewage system optimisation


Client: Confidential
Service division: Optimisation; Engineering
Sector: Marine


AFECO was commissioned by a privately owned superyacht to act as independent process experts in identifying the causes of the poor performance of the on-board sewage treatment system to support an on-going warranty claim. The installed sewage treatment system was designed to meet the effluent standards detailed in the Marine Environment Protection Committee (MEPC) resolution MEPC.2(VI) which was subsequently replaced by resolution MEPC.159(55) but had failed to meet operational standards since its installation.

AFECO was commissioned to survey and re-commission the plant to determine whether the system could be optimised to meet consent requirements as well as to assess the systems performance and carry out an evaluation of the design and previous performance information. The system was re-commissioned following an extensive on-board survey which included identifying all possible sources of influent to the system and reviewing the products used for cleaning to ensure they were suitably biologically friendly. The process performance was evaluated using supporting laboratory analysis and the causes of the operational problems identified and detailed in an extensive report.

The work carried out by AFECO included:

  • Design evaluation
  • Plant loading assessment
  • Full system evaluation including tracing of all possible plant inputs and yacht product usage
  • Process performance evaluation including laboratory analysis
  • Identification of process problems
  • Recommendations for system improvement supported by detailed reporting
