Jaywick is a small coastal village with large caravan parks to the west. The quiet
and sandy beach has recently been extended with additional sand. The fish tailed and
other rock groynes have significantly enhanced the beach.
This bathing water is included in the Surfers Against Sewage “Safer Seas Service”.
This service can alert you to Combined Storm Sewer Overflow discharges via a phone
App and in addition, it includes the Environment Agency Pollution Risk Forecast warnings
where they are available. Further details of the service can be found at - http://www.sas.org.uk/safer-seas-service/
The treatment works at Jaywick was improved in 2001 and this has helped protect bathing
water quality An Anglian Water improvement scheme will be completed by March 2022.
For the four year (2020-2023) assessment period where data is available, seaweed (macroalgae)
was not assessed as being sufficient to be objectionable, but was observed as being
present on 90% of visits. This bathing water does not have a history of large amounts
of seaweed (macro algae). However groynes and rocks, platforms or other fixed objects
may develop 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. Misconnections
in the surface water system were identified following an extensive study by the water
company. Some were corrected when they were found and consideration is being given
to the best way to fix the others.
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 2% 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.
There are no active pollution risk forecasts made at this bathing water. However any
bathing water has the potential to be affected by a pollution incident and if this
occurs a pollution risk warning with associated advice against bathing will be issued
on this website.
The Jaywick and St Osyth ditches flow out to the west of the beach. They run across
the western end of the beach and may be a source of reduced water quality after periods
of heavy rainfall.
Environment Agency samplers make observations of litter present on the beach at every
visit, this includes assessments of sewage debris, litter and tar. At Jaywick for
the four year (2020-2023) 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 81% of visits. Tarry residue was not noted at
this site.
Jaywick is within the Stour and Colne Catchment Sensitive Farming area. This is a
partnership between Natural England and the Environment Agency. Its aim is to work
with farmers to enhance farming practices and reduce run off from farmlands.
The Tendring Peninsula is generally flat, rising to 30 metres above sea level. The
area is predominantly rural apart from the coastal resorts. Agriculture in the catchment
is mixed arable and livestock and there is no heavy industry. Much of the village
is below high water level. St Osyth ditch and Jaywick ditch are near-by (to the west)
and both flow through small rural catchments. The beach is backed by urban areas and
grazing marshes, with arable farming further inland.
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.
