6. Local Authority Pages

Introduction

These pages provide details of drinking water quality data by local authority area. Each area page is divided into public and private supplies. In the public section a summary of water quality compliance data is included for water supply zones which cover the local authority area. It is important to note that some supply zones cover more than one authority area, and where this occurs, the results for the whole zone will be included on more than one authority page.

Details of selected water quality incidents are included under the appropriate local authority area. Tables summarising all water quality incidents may be found in Section 5 under the appropriate region.

DWQR is grateful to local authority environmental health departments for supplying comments on public water supplies and data on private water supplies in their areas. A map showing local authority areas appears below.

ABERDEEN CITY COUNCIL Region: North East Supply zones in Aberdeen City Craigie Glendye Invercannie Mannofield East Mannofield North Mannofield South Mannofield West

Quality of Public Water Supplies

Scottish Water carried out at total of 9,618 tests on tap samples taken in the six water supply zones within Aberdeen City boundary. The table below provides details of the main parameters tested and totals for the other parameters.

There were no manganese failures within the city in 2005. This is in contrast with 2004, when there were 16 failures. Scottish Water has carried out work at Mannofield WTW to install manganese removal, and this would appear to have had a beneficial effect.

The number of samples containing coliforms was 15 in 2005.

Local Authority Comments

Aberdeen City Council Environmental Health Department report that they were generally satisfied with the quality of water supplied to the area by Scottish Water in 2005. They feel that their organisation has a good relationship with Scottish Water and that water quality information provided to themselves and the public during 2005 was generally accurate. They comment that they have received fewer complaints from consumers about water quality in 2005 than in 2004.

Quality of Private Water Supplies

There are 107 private water supplies in the area. These are broken down as follows:

The local authority is responsible for testing and monitoring the quality of private water supplies. Data from samples taken in 2005 are summarised below:

ABERDEENSHIRE COUNCIL Region: North East Supply zones in Aberdeenshire Aboyne, Ballater, Braemar, Craighead, Craigie Crathie, Forehill, Gallowhill Banff, Glendye Herricks, Invercannie, Lintrathen, Lumsden Mannofield East, Mannofield North, Mannofield South Mannofield West, Rhynie, Turriff, Whitehillocks

Quality of Public Water Supplies

Scottish Water carried out at total of 17,975 tests on tap samples taken in the water supply zones within Aberdeenshire. The table below provides details of the main parameters tested and totals for the other parameters.

In common with Aberdeen City, an improvement in manganese compliance was seen as the number of manganese failures fell from eight to one. Coliforms were found in 16 samples taken from supply zones covering Aberdeenshire.

Details of Selected Water Quality Incidents

The freezing of a sodium hypochlorite dosing system during cold weather resulted in a failure of the disinfection process. Although this triggered an alarm at the treatment works and via the telemetry system, human error meant that this was not passed on to the works operator, delaying remedial action. Samples taken soon after the incident was discovered showed the water to be bacteriologically satisfactory.

Scottish Water agreed to improve the systems in place for passing on alarms and to improve the chlorine dosing system at the works to make it more robust.

The DWQR acknowledges the proposed work to improve the system for passing on telemetry alarms and will be monitoring this. It was noted that no samples appear to have been taken to confirm chlorine residuals had been restored following the incident.

Local Authority Comments

Aberdeenshire Council Environmental Health Department did not provide any comments on the quality of the public water supply in their area during 2005.

Quality of Private Water Supplies

Aberdeenshire council area contains by far the largest proportion of private water supplies in Scotland. The council was unable to provide data on private supplies for 2005. In 2004, there were 8,387 private water supplies in the area. The data for 2004 are broken down as follows:

The local authority is responsible for testing and monitoring the quality of private water supplies. No data from samples taken in 2005 was provided by the council. The data shown is 2004.

Local Authority Comments

Angus Council Environmental Health Department report that they were generally satisfied with the quality of water supplied to the area by Scottish Water in 2005, with their own sampling showing only a few sporadic bacteriological failures. They feel that their organisation has a satisfactory relationship with Scottish Water and that water quality information provided to themselves during 2005 was generally accurate, although they would like Scottish Water to more clearly define the area likely to be affected when reporting water quality failures.

DUMFRIES AND GALLOWAY COUNCIL Region: South East Supply zones in Dumfries and Galloway Afton, Auchneel, Barclye, Black Esk, Black Esk Winterhope, Cargen, Carsphairn, Glengap, Kettleton, Killyour, Langholm, Larchfield, Lochenkit, Lochinver, Moffat, Palnure, Penwhirn, Penwhirn Barclye, Penwhirn Palnure, Ringford, Terregles, Winterhope

Quality of Public Water Supplies

Scottish Water carried out at total of 10,919 tests on tap samples taken in the water supply zones within Dumfries and Galloway. The table below provides details of the main parameters tested and totals for the other parameters.

Sample compliance in the area deteriorated slightly for many parameters compared with 2004. The number of samples containing coliforms increased from seven in 2004 to 11 in 2005. The failures for iron increased from 15 to 19 and for trihalomethanes ( THMs) from nine to 13. Many of the failures for the last two parameters originate from the Newton Stewart area, served by Penwhirn and Barclye WTWs.

Details of Selected Water Quality Incidents

A blockage in a chemical dosing system resulted in a loss of coagulation control and water leaving the works in excess of the PCV for aluminium.

A disruption to the coagulation process resulted in poor water quality and standards at the treatment works for turbidity and colour being breached. A telemetry fault meant that operational staff were not notified of the problem and discovered it during a routine visit the following day. Water quality was restored and a number of remedial measures have been put in place to prevent a recurrence.

Local Authority Comments

EAST AYRSHIRE COUNCIL Region: South West Supply zones in East Ayrshire City Afton Amlaird Bradan A Bradan B Corsehouse Daer A Glassford Neilston

Quality of Public Water Supplies

Scottish Water carried out at total of 10,467 tests on tap samples taken in the water supply zones within East Ayrshire boundary. The table below provides details of the main parameters tested and totals for the other parameters.

Details of Selected Water Quality Incidents

A blockage in a chemical dosing system resulted in a loss of coagulation control and water leaving the works in excess of the PCV for aluminium.

Loss of treatment process control resulted in high aluminium concentrations in distribution and resulting exceedences of the regulatory standard. There were no reported exceedences of the aluminium standard in distribution, although there was clearly the potential for this to have occurred. Scottish Water has addressed site specific issues.
