There are no known misconnections in this catchment.
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.
Streams are typically affected by sewage or industrial run off from further up the
catchment. The bathing water is not influenced by any freshwater inputs, the main
river in the area is the Braint and that enters the Menai Strait south of the beach
and is not known to have any impact on bathing water quality.
It is 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. The following sections serve to highlight potential sources of
pollution, conditions under which they may arise and measures being put in place to
improve water quality.
