history statement The need for sewage treatment around the northern part of St Austell Bay was identified to protect the bathing waters at Polkerris, Par, Shorthorn, Crinnis, Charlestown, Duporth and Porthpean. The South West Water sewage treatment scheme for Polkerris, which provides fine screening, was completed in 2003. A sewage treatment works (STW) for Par at Merthen Farm (north of Crinnis) was built by South West Water in 1992 and commissioned in 1993. The scheme included the collection of sewage from Par, Charlestown, Duporth, Porthpean and part of the St Austell catchment, and transfer via a tunnel sewer to Par STW where it receives secondary treatment before being discharged through a 1.3 kilometre (km) sea outfall south of Fishing Point in St Austell Bay. The scheme also included extensive resewerage and removal of various untreated discharges and a primary treated effluent discharge at Par Spit. The storm tank at Par STW and Harbour Road (No.2) pumping station storm overflow were improved by April 2006. The sewage treatment scheme for St Austell North (Luxulyan), which provides secondary treatment and ultraviolet (UV) disinfection, was completed in early 2006. Improvements to the storm discharge from St Austell North STW were also made at that time.
local authority statement The urban area of Porthpean immediately behind the beach is served by a combined (surface and sewer) system. There is a surface water outfall from the slipway. more like this
macro algae statement For the four year (2015-2018) assessment period where data is available, seaweed (macroalgae) was assessed as being sufficient to be objectionable for 8% of visits, with 86% of visits noting the presence of seaweed (macroalgae). The bathing water can become covered with large amounts of seaweed, depending on tides and the weather. This bathing water does not have a history of large amounts of seaweed, but that it can be noticeable from time to time. more like this
phytoplankton statement For the four year (2015-2018) 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 4% of visits. 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. more like this
stw outfalls statement The outfall from Par STW discharges to the sea approximately 3.4km east of this bathing water. This discharge is designed to protect bathing water quality. more like this

visible pollution statement Environment Agency samplers make observations of litter present on the beach at every visit, this includes assessments of sewage debris, litter and tar. At Porthpean for the four year (2015-2018) assessment period where data is available, sewage debris was not assessed as being sufficient to be objectionable, but was observed as being present on 2% of visits. Litter was not assessed as being sufficient to be objectionable, but was observed as being present on 32% of visits. Tarry residue was not noted at this site. more like this
working with farmers statement During and after periods of heavy rainfall, runoff from agricultural land is greatly increased, and the quality of the bathing water can be reduced. more like this
zoi description The catchment surrounding Porthpean is approximately 48 hectares. There is a tiny stream 250m long which flows through Lower Porthpean before entering the sea at the southern end of the beach. The catchment slopes steadily from the west to the east. A large part of the catchment is taken up by a golf course, and the rest is urban and agricultural land with just one or two farms. The small settlements of Higher and Lower Porthpean are in the south of the catchment. 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 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. 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 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. more like this
stw outfalls general statement Discharges from sewage treatment works have improved substantially in England since the 1980s. more like this
