SCOTTISH Water has been fined £7,500 for pollution of the Caaf Water and River Garnock in Dalry.

The corporation pled guilty at Kilmarnock Sheriff Court to causing or permitting other persons to draw down the level of water in the Caaf Reservoir through an inadequately monitored open valve. This resulted in the discharge of sediment laden water, containing a high level of suspended solids from the reservoir, into the Caaf Water and the River Garnock on May 24 2015.

The Scottish Environment Protection Agency (SEPA) carried out an investigation after complaints from members of the public about the discolouration of the Caaf Water.

SEPA contacted Scottish Water to close the valve draining the reservoir in order to stop any further polluting discharge, and reported the matter to the Procurator Fiscal.

John McCabe, SEPA’s Reporting Officer, said: “The Caaf Water and River Garnock are very popular with countryside enthusiasts including anglers. As a result of this incident, water heavily contaminated with sediment from the Caaf Reservoir was introduced into these downstream watercourses at a concentration well beyond what would occur naturally, and this pollution remained visible for several days.

“If Scottish Water had been monitoring the reservoir out of hours when the incident occurred, then it is likely the pollution to these rivers could have been prevented. ”

In imposing the fine, the court said it was a serious failure which resulted in detriment to the wildlife, but the long term impact was unknown.
