bathing water description The bay faces south towards the Bristol Channel and is approximately 650 metres in length, with the harbour and promenade to the west, Coney Bay Amusement Park to the north and Rhych Point to the east. The beach is sandy and gently sloping. The water quality sample point is located at the centre beach, opposite the car park. more like this

eso outfalls statement Storm sewer discharges near Irongate Point, Hutchwns Point, Newton Point and Newton Bay can operate when heavy rainfall overwhelms the sewage system. These protect domestic properties in the catchment from being flooded by sewage and storm water during heavy rainfall. There are numerous storm outfalls that discharge into the river Ogmore and its tributaries near to Sandy Bay. Water quality in streams or rivers may decline after periods of heavy rainfall. more like this
history statement Natural Resources Wales has developed a good working relationship with Dŵr Cymru Welsh Water and liaises regularly to identify problems that could affect bathing water quality. more like this
investigations statement Natural Resources Wales works with the local authority, Dwr Cymru Welsh Water and any privately permitted discharge consent holders to establish and resolve potential sources of pollution affecting water quality at Sandy Bay. 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 15th of May) and mid season if required (during the bathing water season). more like this
local authority statement Natural Resources Wales works with Bridgend County Borough Council to safeguard bathing water quality at Sandy Bay. Pre-season inspections are conducted in liaison with the local authority. Natural Resources Wales is a member of the Newton &Trecco Bay Management Group, facilitated by the local authority (this group does not currently have Sandy Bay within it's remit, however many relevant stakeholders attend). more like this
macro algae statement This bathing water does not have a history of large amounts of seaweed (macroalgae). more like this
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. Misconnections can occur in any modern urban area. more like this
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. more like this
streams rivers statement Streams are typically affected by sewage or industrial run off from further up the catchment. During and after periods of heavy rainfall, run off from agricultural and urban areas will be greatly increased. This bathing water is also located close to the estuary of the River Ogmore. This has a large and varied catchment, which can be influenced by agricultural, urban and industrial areas. This may result in deterioration in bathing water quality at Sandy Bay following periods of heavy rainfall. more like this
stw outfalls statement Pen-y -Bont Wastewater Treatment Works discharges into the tidal stretch of the River Ogmore, approximately 5 kilometre to the East of Sandy Bay. Disinfection through ultra-violet treatment, which is designed to reduce the levels of bacteria in the final effluent, which will help improve bathing water quality is carried out. Pen-Y-Bont Wastewater Treatment Works also has a storm outlet which, when operating during times of heavy rainfall, will discharge screened effluent into the River Ogmore. more like this

visible pollution statement Natural Resources Wales samplers make visual observations of the beach at every visit.  This includes assessments of sewage debris, animal faeces, litter and oil or tar. At Sandy Bay Porthcawl, data are available for the four year assessment period from 2015-2018. Sewage debris was observed in trace amounts on over fifty per cent of occasions and in greater amounts on one occasion in August 2015. Trace amounts of animal faeces were noted at the site on a minority of occasions. Trace amounts of litter were observed at the bathing water the majority of the time and in greater amounts on over thirty per cent of additional occasions. Oil and tarry residues were not noted at this site. more like this
working with private owners statement Natural Resources Wales continues to work with private owners regarding potential pollution sources to the bathing water. This work involves, where necessary, advisory mail drops, dye tracing and misconnection surveys. Poorly maintained private sewage treatment facilities could be a source of pollution, therefore the registration of all qualifying private sewage systems in Wales was required by 30 June 2012. The primary aim of this exercise is to provide increased protection for the environment and sensitive features such as bathing water beaches. Where discharges from properties are identified in the catchment that are not on mains sewerage, Natural Resources Wales will endeavour to ensure registration has been made, unless already a permitted discharge. more like this
zoi description The natural drainage (hydrological) catchment surrounding the bathing water is highly diverse. The town of Bridgend is located in the lower catchment, with several smaller urban areas, located along the length of the tributaries of the River Ogmore. These areas are a mixture of residential and light industry. Further into the catchment, there are some forested areas and upland hill farming, predominantly sheep. more like this

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. more like this
eso outfalls general statement The majority of sewers in 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. more like this
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. more like this
pollution management general statement 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. more like this
