There are storm and emergency outfalls that discharge to the sea, and to the Buck
Beck, Louth Canal and Laceby/Freshney catchments. These are designed to operate only
during emergencies or heavy rainfall and to protect properties from being flooded
by sewage. 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

Anglian Water has worked with the Environment Agency over a long period to help make
improvements to their sewerage infrastructure in and around Cleethorpes. Significant
improvements have been carried out to Sewage Treatment Works, the pumping stations
and sewage infrastructure. This has contributed towards major improvements in bathing
water quality.
The Environment Agency regularly carries out investigations to identify sources of
pollution in the catchment. The Environment Agency does this by monitoring the quality
of streams and visiting sites. The Environment Agency gives advice on compliance with
regulations and good practice as appropriate.
The Environment Agency works with North East Lincolnshire Council (NELC) to identify
and rectify issues that may impact bathing water quality. NELC promotes sustainable
tourism and is involved in a number of campaigns to raise awareness and to reduce
contamination from pollution, litter and dog fouling.
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 49% of visits. This bathing water does not have a history of large amounts
of seaweed (macro algae). The beach is sandy.
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 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. There may
be occasional brown foam at the edge of the water or on the beach, this is due to
algae in the water breaking down.
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, wind 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 11 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 are several rivers which flow into the sea close to Cleethorpes bathing water.
These rivers will receive run off from both urban and rural areas, which may have
the potential to reduce bathing water quality. The Environment Agency works to improve
water quality and rivers and reduce potential sources of pollution.
There are two large Sewage Treatment Works nearby: Newton Marsh sewage treatment works,
serving Cleethorpes town was fitted with ultra violet disinfection in 1995. This works
discharges to Tetney Haven, to the the south of the bathing water. Pyewipe (Grimsby)
Sewage Treatment Works, to the north was improved by Anglian Water in 2001 to protect
the bathing water quality of the area, and discharges via a long sea outfall. The
treated sewage from these works is not believed to impact bathing water compliance.
Environment Agency samplers make observations of litter present on the beach at every
visit, this includes assessments of sewage debris, litter and tar. At Cleethorpes
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 29% of visits. Tarry residue was not noted at
this site.
The Environment Agency works with farmers to promote best practice and reduce potential
sources of contamination. Part of the catchment area around Cleethorpes is within
a Catchment Sensitive Farming Medium Priority area, and part of the Laceby Beck catchment
is within a High Priority area. Catchment Sensitive Farming (CSF) is a partnership
between Defra, the Environment Agency and Natural England. It works with farmers
to reduce water pollution from agriculture.
The Buck Beck, the River Freshney, Laceby Beck and Louth Canal flow through urban
and rural areas before reaching the sea. There is some industry in the in lower reaches
of the Freshney River. The Buck Beck outflows to the sea 2.5 km to the south of the
beach, the River Freshney and Laceby Beck 4km to the north, and the Louth Canal approximately
5km to the South. Close to the beach are urban areas.
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 role of the Environment Agency 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.
