Turbidity

Muddy river

Helping you minimise the effect of turbidity

The measurement of turbidity, the cloudiness or haziness of a fluid, is a key test of water quality. Heavy rainfall causes increases in the levels of suspended particles in rivers, increasing the level of treatment needed and therefore the cost incurred in bringing the untreated water up to drinking water quality. This additional treatment can increase the cost of production by up to five times.

About the turbidity model

Our turbidity model enables the relationship between heavy rainfall and turbidity to be modelled, helping you to manage resources and minimise the impact of high turbidity events.

We will work with you to establish the relationship between rainfall and high turbidity events. This understanding can be used to set up a forecast service to help you predict when river conditions will be difficult or expensive to treat, providing guidance to your Control Centres.

Key benefits

  • Predict high turbidity events with our operational forecasts
  • Reduce the amount of chemicals needed to treat water reducing expenditure
  • Abstraction at treatment works can be scaled back gradually and other resources used

Alternatively:

  • Network storage can be increased in advance of a predicted increase in turbidity so that the output from treatment works can be reduced

"The solution was designed and delivered to one of South West Water's works in Cornwall and has proved so successful that we are continuing work to establish the possibilities of implementing it on our river sources in Devon." Mike Wigmore, South West Water.
