bathing water description |
This is a small and tidal cove, found on the south east of the Gower peninsular. On
a high tide the beach is almost non-existent and pebbly, but on a low tide, the sand
is exposed, along with numerous rock pools. A coastal path joins Limeslade with Rotherslade,
Langland and Caswell Bay. The water quality sample point is located at the centre
of the Bay.

eso outfalls statement |
Limeslade Pumping Station has an emergency overflow, which can discharge to the west
of the beach. It has not been known to discharge during the bathing water season over
the last five years.
Mumbles (Knab Rock) Sewage Pumping Station has an emergency and storm overflow, approximately
a mile from the water quality sample point. This can discharge off Mumbles Head, but
only at certain times of an ebbing tide.

history statement |
Until 1999, Swansea's sewage was discharged directly to the sea from the Mumbles Headland,
less than 1.5 kilometres away. In 1999, Swansea's sewage system was significantly
upgraded, when a new Wastewater Treatment System was installed at Fabian Way. This
resulted in a vast improvement to the water quality at Limeslade Bay.
More recently, Natural Resources Wales has been working with Dŵr Cymru Welsh Water
to trace the sources of pollution in the public and private surface water drains of
the Limeslade catchment.

investigations statement |
Natural Resources Wales works to establish sources of pollution around Limeslade Bay.
Some of this work is carried out in partnership the City and County of Swansea and
Dŵr Cymru Welsh Water.
Inspections are carried out by Natural Resources Wales in partnership with the local
authority and the water company. These are carried out pre-season (before the 1st
of May) and mid-season if required (during the bathing water season).
Following several bathing water sample failures, Natural Resources Wales carried out
visual inspections and water quality sampling of the culverted surface water drain.
Investigations concluded that the drain was polluted by wrongly connected waste water
pipes from household sinks and washing appliances.
It is believed that, this has been the cause of some bathing water failures at Limeslade.
Natural Resources Wales has been working with the City and County of Swansea and Dŵr
Cymru Welsh Water to trace the pollution back to individual properties and resolve
the problem.

local authority statement |
Natural Resources Wales works closely with the City and County of Swansea to monitor
and maintain bathing water quality at Caswell. Meetings are held on a quarterly basis.
Investigations and inspections are carried out in collaboration.
At Limeslade, Natural Resources Wales has been working with the City and County of
Swansea to trace the sources of pollution in the public and private surface water
drain back to individual properties. The Council then work with the owners to stop
the pollution at the source.

macro algae statement |
This bathing water does not have a history of large amounts of seaweed (macroalgae). |

misconnections statement |
Modern sewerage systems have two separate systems, one takes foul sewage to sewage
treatment, the other takes rainwater runoff through surface water drains to rivers,
lakes and the sea. Misconnections occur when waste water pipes are plumbed into surface
water drains instead of the foul water sewerage system. This can give rise to pollution
when the waste water is discharged directly to the environment through the surface
water drain. For example, a washing machine or toilet may be incorrectly plumbed so
that it discharges to the surface drain rather than the foul sewage drain.

phytoplankton statement |
Phytoplankton (microscopic algae) naturally increase in number at certain times of
the year. This process is known as a phytoplankton bloom. These algal blooms can occur
at any beach during the bathing season and are usually noticeable by a surface scum.
This beach has a history of such blooms.

zoi description |
The natural drainage (hydrological) catchment surrounding the bathing water is a narrow
steep valley. There are no watercourses running onto the beach, but the rocks in the
area are limestone, which allows any rainfall to percolate through the rock fissures
and resurface at the beach. Some of the rain falling in the catchment is directed
into a surface water drain, which flows onto the rocks at the top of the beach.
The area is relatively urban and residential, with a cricket ground and allotments
at the top of the valley.

algae general statement |
Seaweed (macroalgae) and phytoplankton (microscopic algae) are a natural part of the
marine and freshwater environment. Below we note whether these have been recorded
in quantities sufficient to be a nuisance.

eso outfalls general statement |
The majority of sewers in England and Wales are “combined sewers” and carry both sewage
and surface water from roofs and drains. A storm overflow operates during heavy rainfall
when the sewerage system becomes overwhelmed by the amount of surface water. The overflow
prevents sewage from backing up pipes and flooding properties and gardens. An emergency
overflow will only operate infrequently, for example due to pump failure or blockage
in the sewerage system.

local authority general statement |
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 as a result of such events.

pollution management general statement |
It is the Environment Agency and Natural Resources Wales role to drive improvement
of water quality at bathing waters that are at risk of failing European 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.
