Eel Screens and Eel Regulations Compliance

Complying with the Eel Regulations – Our Self-cleaning Filters are Eel Friendly.

If you are pumping and screening raw water you may be affected by the current Eel Regulations designed to help the recovery of populations of European Eels. The relevant legislation in the UK is ‘The Eels (England and Wales) Regulations 2009 Statutory Instrument No. 3344’.

The installation of low intake velocity eel screens ahead of pumping equipment may be a condition of your water abstraction licence.


What’s happening to the Eels?

Eel regulations - an eelThe regulations have come about due to a catastrophic decline in the eel population – succinctly described here in the Environment Agency Eel Manual Overview.

The regulations set criteria for the use of raw water and screening and pumping equipment. In simple terms, the regulations seek to ensure that Eels at all stages of life are protected.

The Eel regulations are concerned, in part therefore, with the intake velocity of pumps screens and strainers, the angle of approach and the size of mesh.

Serendipitous Design

Eel friendkly filter complying with eel regulationsBy happy chance the design of Rotorflush self-cleaning suction intake filters lends itself to compliance with current Eel Regulations. Rotorflush self-cleaning suction intake filters make ideal eel screens ahead of pumping equipment when abstractiong raw water.

Our filters operate by drawing a high volume of water through a large open area at low velocity, and backwashing debris wildlife etc. away from the mesh from inside the filter.

For most flow rates our filters meet requirements for the protection of all eels, including elvers.

Does this affect me?

The Eel Regulations affect all industry sectors abstracting, diverting or discharging into raw water, and may apply to you if:

  • you abstract more than 20 m3 in any 24 hour period
  • you have equipment (pumps, screens filters etc) that may obstruct Eels
  • or if you are installing or altering equipment that may obstruct Eels

Who is affected, who is exemptPiscesConservation1


glasseel1The Eel Regulations require companies in the UK and the EU who abstract and use raw water to ensure that their activity enables at least 40% eel “escapement”.  This is a requirement that came into force in 2015.

Ensuring that this figure is met may require specialist input by conservationists such as Pisces Conservation.

Companies can meet this and other requirements by implementing measures that reduce the harm to eels and elvers from pumping equipment and intake and outfall screens.

The Environment Agency (EA) has noted that Rotorflush filters can make an important contribution to Eel recovery, particularly for seasonal or temporary pumping applications   Section 4.5.1 of the EA “Screening at intakes and outfalls: measures to protect eel” says:

“Few manufacturers offer self-cleaning strainers that are appropriate to temporary works. One of the few available is the Rotorflush RF Series of self-cleaning inlet screens for surface-mounted pumps.”

The design of our filters gives them a low intake velocity and a high open area, enabling compliance with current Eel regulations when pumping and abstracting raw water.
