Case Studies

We publish two different (but closely related) types of case study;

  • Case Study: These are used in-house as training aids and we publish abbreviated versions of some of these on our web-site and our Newsletter.
  • Validation Study: These are used to test and improve our simulation models. We frequently compare the simulation program against site data to ensure superb accuracy.

This months selection of Case & Validation Studies are listed on the left, and a few short studies are discussed below.

  • A rising main was performing erratically and unpredictably. Our consultants identified that air would collect at locations along the pipe and would not be removed by the air valves chosen at design stage. This air was shown by simulation to be a cause of the unpredictable and excessive pressures
  • During an international audit we found that a surge study undertaken by a non-specialist consultant predicted surge pressures that were 100% in error
  • The capacity of a rising main was found to be lower than expected; on-site tests and the use of a simulation model as a 'what-if' tool allowed our engineers to identify and accurately locate a blockage. As a result, only a small section of pipe had to be excavated.
  • A surge study undertaken by our specialist engineers allowed large surge vessels (recommended by less specialised consulting engineers) to be removed from the design. The associated capital costs saved were significant.
  • A pipeline was being shutdown temporarily due to a directorate enforced by a legislative body. We helped to find suitable operating regimes that enabled continued operation with the eventual condolence of the legislative body.
