  • history statement
    In the past the main water company assets affecting this bathing water were from four storm overflows from the tunnel sewer along Bournemouth seafront. These overflows were Hengistbury Head, Bournemouth No 1, Boscombe Pier and Fisherman's Walk. Improvements were made to Fisherman's Walk by Wessex Water in 1993. Hengistbury Head pumping station (PS) and combined sewer overflow (CSO), and Boscombe Pier CSO were improved in early 1999. Bournemouth No.1 PS and CSO were improved in June 1999. Improvements to the treatment capacity and storm storage at Holdenhurst Sewage Treatment Works (STW) were completed in 1994. Ultraviolet (UV) disinfection and additional storm storage was installed at Holdenhurst STW by April 2001. In 2009 the CSO at Branksome Chine, which is part of the East Poole drainage system, was also improved.
  • macro algae statement
    For the four year (2018-2021) assessment period where data is available, seaweed (macroalgae) was not assessed as being sufficient to be objectionable, but was observed as being present on 62% of visits. This bathing water does not have a history of large amounts of seaweed (macro algae).
  • phytoplankton statement
    For the four year (2018-2021) assessment period where data is available, phytoplankton (microscopic algae) was assessed as being sufficient to be objectionable for 4% of visits, with 4% of visits noting the presence of phytoplankton (microscopic algae). Phytoplankton (microscopic algae) naturally increase in number at certain times of the year. This process is known as a phytoplankton bloom. This bathing water does not have a history of phytoplankton blooms. 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.

    • 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 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 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.
    • stw outfalls general statement
      Discharges from sewage treatment works have improved substantially in England since the 1980s.
