Catchment Description

Brewery Bay surface water catchment boundary map

The catchment surrounding Bay ny Carrickey beach is approximately 1.44 km2.

The Colby river and Cott ny Greiney stream discharge into the bay either end of the designated bathing water. The surrounding catchment is mainly agricultural with small urban areas. During adverse weather there is a likelihood that the nutrient concentration from the rivers discharging into the bay are elevated which could increase the concentrations of bacteria.

Pollution Risk Forecasts

This bathing water is subject to short term pollution. Short term pollution is caused when heavy rainfall or high tides wash faecal material into the sea from livestock, sewage and urban drainage via rivers and streams. At this site the risk of encountering reduced water quality increases after rainfall and typically returns to normal after 1-3 days.

Investigations Statement

The Environmental Protection Unit is not currently investigating any pollution incidents within this catchment. To report any water pollution; please call +44 1624 685885 or email

Pollution Management

It is the Environmental Protection Unit's role to drive improvement of water quality at bathing waters that are at risk of failing higher standards. It is natural for water to run off the land to the sea. Water quality at a bathing water is dependent upon the type and area of land (the catchment) draining to the water and the activities undertaken in that catchment.

Stream and Rivers

The annual report on the routine water quality monitoring data is produced by the Environmental Protection unit.

Any reports of pollution will be investigated by officers and water samples collected if necessary.

Working with Manx Utilities

Brewery Bay combined sewer overflows map

The urban areas of Gansey and Port St Mary have combined sewer networks. These networks are maintained by Manx Utilities with the foul waste being transported to Meary Veg sewage treatment works via the IRIS network.

Due to the combined sewer networks serving nearby residential areas, during periods of adverse weather the combined sewer overflows at Gansey Point, Gansey Mill and The Shore Hotel may discharge into the rivers which lead into the bay. Modelling of the Manx Utilities infrastructure shows this is not likely to impact on the bathing water quality.

Manx Utilities are working to review the Gansey Mill overflow through network modelling and monitoring to determine the frequency and quantity of spills. With this data they will be able to determine if the overflow is necessary and if so install a screen and telemetry to further protect bathers at this location during periods of adverse weather.

Working with Local Authorities

Surface water can flow into the sea from outfalls and highway drains. This can affect water quality, particularly after periods of rainfall.

Heavy rain falling on pavements and roads often flows into surface water drains or highway drains, ending up in local rivers and ultimately the sea. The quality of bathing water may be adversely affected because of such events.

Working with the farming community

During and after periods of heavy rainfall, run off from agricultural areas is greatly increased, and the quality of the bathing water may be adversely affected. The Environment Protection Unit are working with farmers to encourage better farming practices and improve water quality in the surrounding areas.
