2024 Bathing Water Profile for Margate Fulsam Rock

  • The bathing water is a resort beach on the north Kent coast close to Margate town centre. It is a gently shelving sandy beach with a harbour wall at the western end and a lido at the eastern end. There are extensive underwater rock formations just offshore along the length of the beach which are exposed at low water. A promenade sits above the beach with public gardens behind.
  • There are storm overflows about 900m west of the bathing water and a further storm overflow 1.5 km to the west. Discharges from these storm overflows occur when heavy rainfall overwhelms the sewerage system but the overflows are designed to ensure that bathing water is protected.
  • Prior to 2007, treated sewage was discharged from Margate long sea outfall 4 km from the bathing water. Since 2007, flows from Margate long sea outfall, together with flows from Broadstairs long sea outfall, have been transferred to Weatherlees sewage treatment works for further treatment and UV disinfection. The treated sewage is then discharged out of Margate long sea outfall. Under the programme of works for Southern Water (from 2020 to 2022) investigations within the catchment were carried out. This will help to identify where bathing water improvements may be needed in the future.
  • For the four year (2020-2023) assessment period where data is available, seaweed (macroalgae) was assessed as being sufficient to be objectionable for 2% of visits, with 83% of visits noting the presence of seaweed (macroalgae). The shore can become covered with seaweed, depending on tides and the weather. Groynes, rocks and other fixed objects may have a covering of seaweed which can be slippery.
  • 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.
  • For the four year (2020-2023) assessment period where data is available, phytoplankton (microscopic algae) was not assessed as being sufficient to be objectionable, but was observed as being present on 5% of visits. Phytoplankton (microscopic algae) increase in number at certain times of the year. This process is known as a phytoplankton bloom. Blooms of phytoplankton can result in the water appearing discoloured or a foam forming on the water. The risks to human health from contact, ingestion or inhalation with marine algae that currently occur in UK coastal waters are considered to be low. However, some individuals may be more sensitive and display some reactions. A common marine algae found in UK coastal waters is Phaeocystis, which is often mistaken for sewage as it forms foam and a brown scum, but it is non-toxic.
  • This bathing water is subject to short term pollution procedures. The Environment Agency makes a daily pollution risk forecast at this site based on the effects of rain, tide and seasonality on bathing water quality. These factors affect the levels of bacteria that get washed into the sea from livestock, sewage and urban drainage via rivers and streams and how they disperse. When these factors combine to make short term pollution likely we issue a pollution risk warning on this website and the beach manager will display a sign advising against bathing at the bathing water. After a short term pollution event, levels of bacteria typically return to normal after a day or so but it’s possible to have several warning days in a row. Details of the work to reduce the sources of bacteria at this bathing water are detailed in this profile. In 2023 no pollution risk warnings were issued for this bathing water. All bathing waters have the potential to be affected by a pollution incident and if this occurs a pollution risk warning will be issued with associated advice against bathing on this website.

  • There is an underground culverted stream which enters the sea through an outlet nearly 1 km to the west of the bathing water The stream drains surface water from the surrounding urban area, this can lead to reduced water quality after rainfall in the adjacent area.
  • There is a treated sewage treatment works discharge 4 km from the shore of this bathing water which is designed to protect bathing water quality.
  • Environment Agency samplers make observations of litter present on the beach at every visit, this includes assessments of sewage debris, litter and tar. At Margate Fulsam Rock for the four year (2020-2023) assessment period where data is available, sewage debris was not noted at this site. Litter was not assessed as being sufficient to be objectionable, but was observed as being present on 35% of visits. Tarry residue was not noted at this site.
  • The bathing water is situated in a low lying area. The natural drainage (hydrological) catchment surrounding the bathing water is approximately 10 hectares and comprises just the local urban area.

    • 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.
    • The majority of sewers in England 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.
    • 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.
    • It is the Environment Agency 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.
    • Discharges from sewage treatment works have improved substantially in England since the 1980s.
