Water Intake Solutions

Water from surface sources is used for many reasons and purposes; be it by municipalities for drinking water treatment or by industry (such as Desalination, Energy, Land Drainage, Irrigation and Hydropower, Oil & Gas, Petrochemical) for make-up and cooling. Ovivo’s combination of passive or mechanically cleaned screens and fish protection solutions are specifically designed to meet the challenges and considerations that need to be kept in mind in the design of a suitable intake. Additionally, further downstream finer filtration as well as the on-line removal of scaling and fouling material is achieved using Ovivo’s performance enhancing equipment.

Further Details

Ovivo offers a full line of equipment for use in the design and provision of intakes from raw water intake screens for conventional potable water treatment plants to multi-million combined cooling water intakes for industrial use. Ovivo’s design and engineering teams have the expertise to provide the high quality equipment needed. 

Together with a number of challenges (specified below) and considerations that need to be kept in mind in the design of a suitable intake, our experience in water abstraction has also led us to look closely at our environmental responsibilities, with particular focus on fish protection and handling systems. 

  • Almost all surface water will contain debris of one sort or another (from solid waste to jellyfish swarms) that has the potential to damage an intake pump or downstream installations and, as such, it must be removed
  • Debris must be conveyed to safe disposal point, which may be some distance from the intake - and almost certainly at a different level - and in a suitable manner for discharge
  • Debris loading can vary; conveying systems must be designed to be sufficiently robust to cope with heavy loads
  • Additional debris grown inside the intake piping as well scale and fouling of the downstream process equipment has to be eliminated.
  • Water levels in rivers and lakes can vary from season to season, while in tidal areas level changes can be dramatically dependent on the state of the tide
  • Increasingly, abstraction licences are only granted after a suitable environmental impact assessment has been completed, and these often take into account the impact on local aquatic species
  • Design volume of flow required
  • Intake equipment must perform reliably 24/7 in some of the world’s most challenging environments.  Robust design and ease of maintenance are important considerations.

All of these factors must be taken into account to ensure an effective and reliable raw water intake and cooling water system design, and Ovivo, through its Brackett Green technology, is one of the  most respected brands in the world.
