2013 Bathing Water Profile for Lusty Glaze

  • Lusty Glaze is a privately owned beached in Newquay Bay on the north coast of Cornwall. It is a sandy beach resort approximately 220 metres wide backed by cliffs and the town of Newquay.
  • Cornwall
  • The sewage treatment scheme for Newquay, which provides secondary treatment and ultraviolet disinfection, was completed by South West Water in April 2000. Extensive sewerage work to combined sewer overflows in the Newquay area was also carried out at that time.
  • The urban area of Newquay immediately behind the beach is served by a combined (surface and sewer) system. There are no outfalls from the system onto the beach.
  • This bathing water does not have a history of large amounts of seaweed (macroalgae).
  • 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.

  • Streams and rivers are typically affected by human sewage, animal slurry and runoff from roads. The Porth Stream flows the sea 350m northeast of this beach. The Environment Agency have monitored the stream since 1990 and found that it does not affect the bathing water.
  • The outfall for the Newquay STW discharges into the sea approximately 2.4km northwest of Lusty Glaze bathing water at Towan Head. This discharge is disinfected and designed to protect bathing water quality.
  • The catchment surrounding Lusty Glaze is approximately 3,680 hectares. There is no stream which enters the sea at this bathing water, however, the mouth of the Porth Stream is 350 metres (m) to the northeast. The Porth (Whipsiderry) Stream is approximately 12 kilometres (km) (18km long including major tributaries) and rises near Ruthvoes at the eastern edge of the catchment close to the A30. The stream feeds the Porth Reservoir eight kilometres inland then flows to the coast at Porth where it enters the sea at the northern end of the beach. The steep catchment means rain runs off rapidly into the stream especially towards the coast. Land use is mostly agricultural, with around 20 farms. The rural areas are a patchwork of improved grassland, arable and mixed woodland. The urban areas include parts of Newquay, St Columb Major and Indian Queens and there are caravan sites within the catchment.

    • 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 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.
    • 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 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.
    • Discharges from sewage treatment works have improved substantially in England and Wales since the 1980s.
