Introduction by Siân Caiach
At the end of the 1990's a disastrous decision was made to "upgrade" the sewerage treatment in the Llanelli and North Gower areas which discharged into the Burry Inlet.(Loughor Estuary) The small settlement plants were closed and all sewage pumped up to Bynea and Gowerton where the foul discharge was treated by UV light. Unfortunately the plants were designed to take "dry" sewage, the assumption was that only sewage was in the sewers. In fact, massive amounts of surface water drained into the sewers and very soon the sewage plant was overwhelmed. Untreated and partially treated sewage was released into the natural waterway in increasing volumes. Huge attenuation tanks were built into the system to try to hold back the huge volumes after rainfall. After a few years the shellfish fishery was severely affected with mass cockle deaths every summer. The most likely cause of this was eutrification, too much fertiliser in the water causing algal blooms and killing the animals by asphyxiation. Not only cockles but other animals who could not move away from the sand banks such as sand eels and lug worms, were decimated. Fearful of admitting that this was a man made disaster, convinced by the Carmarthenshire County Council that massive house building was the only development possible in the area, and assured by Welsh Water that they could not afford to put things right, a Welsh Government led cover up was organised to convince everyone that although there was incontrovertible evidence that the sewage was not being treated, there was some other reason that the cockles were dying. As a County Councillor 2008-17 I was told on several occasions that the protests were only about getting compensation for the cockle gatherers and I should not be supporting them. When the Stradey Residents Association reported the matter to the European Commission is was hoped that the environmental protection of the EU directives would save the day.

Here is Robin Burn's excellent summary of events.
A Fisheries Tale
The Loughor Estuary and Burry Inlet, that part of
Carmarthen bay, bounded to the north by the southern coastline of the county of
Carmarthen, and to the south by the north shore of the Gower Peninsular is
identified by Natural Resources Wales as being environmentally sensitive. To be
precise designated as the Carmarthen Bay and Estuaries special area of
conservation (SAC),site of special scientific interest (SSSI), the Burry Inlet
special protection area (SPA) and is an internationally important wetland
site (RAMSAR).
Of importance for the
local economy, the Burry Inlet supports a cockle fishery and has supported this for many years. So
important that Sian Jenkins Hughes,
Fisheries Technical Officer of Natural Resources Wales went so far as to
announce that “ Our environment
in Wales is the most valuable natural asset we have and we have the potential
to generate more for our economy if we use it sustainably”.
This was for the occasion of the launch of Seafish’s Risk
Assessment for Sourcing Seafood (RASS) website.
Careful analysis of the content of the website casts doubt
however on the viability of the fishery, from the mixed messages delivered in
the text .Quoting from the overview of the fishery, it states that “Burry
Inlet cockles have been subject to unexplained summer mortalities in recent
years(Elliot et al(2012). NRW are currently reviewing the recommendations of
the 2012 report with a view to further progress this area of work subject to
available resources”.
It further states “The
Burry Inlet Cockle Fishery Order 1965 Management Plan sets out Natural
Resources Wales aim to develop a thriving cockle fishery in the Burry Inlet
that supports, protects and enhances the needs of the community and the
environment upon which it depends to:
avoid adverse
effects on the European designated site and local residents”
In the section designated Stock status quote”The Burry Inlet
cockle stock has been scored a moderate risk This is because although the
cockles are characterised by relatively low vulnerability (www.sealifebase.org) recent years have
seen a declining trend in the population”.
In the Habitat subsection it quotes that”The seabed effects
of the fishery are scored a very low risk. The Burry Inlet is a European Marine
Site designated for nature conservation and the management plan requires
avoidance of adverse effects on the site”.
In the Outlook subsection, the website script advise, a
moderate stock risk status an uncertain out look on the basis of atypical summer
mortality of stocks, the cause of which is still being investigated with emphasis
on pathogens and biosecurity.
Following the launch of the website and press release, the
September 21st edition of the Llanelli Star reports on a meeting
with the Welsh Governments Environment Secretary , Lesley Giffiths, with
Llanelli’s MP Nia Griffith and AM Lee Waters, to raise the on-going concerns
about the lack of progress to tackle issues facing the cockle industry, of
cockle deaths and sewage problems.
A statement from the Welsh Government spokeswoman suggested
the previously commissioned investigation found no evidence to suggest
pollution in the Burry Inlet waters.
The first indication that all was not well with the handling
of waste water in from the urban areas of the northern boundery, the southern
coast of Carmarthenshire, from the three rivers estuary at the eastern end to
the Burry inlet at the western end, came from a public notice in November
of 2008, of a request by Welsh Water/ Dwr Cymru to the then Environment Agency
for an application of consent to
discharge sewage in an emergency situation.
At the same time a request for consent to diascharge
into Dyfatty Brook from storm sewage overflow at Bryn avenue CSO in Burry Port was lodged.
At the time emergency sewage discharge consent was in place in Burry Port
from the Heol Vaughan pumping station into the Khymer Canal.
Representations of
concern were made on the 5th of December 2008 to the Envronment
Agency, a reply issued by the Agency was made on the 11th of
February 2009. The Agency confirmed that “the applications were consented as
they are for improvements under the AMP scheme to existing assets in the area.
The new pumping station proposal is to replace an existing pumping station
and will not discharge under storm conditions. The consent is for discharge in
an emergency only.
The application for the combined sewer overflow is to
replace two existing combined sewer overflows in the area. The new overflow
will have extra storage and limit the spill frequency to one spill a year.
In the period between the 5th of August, until the
9th of November 2008 ,three heavy rainfall events occurred, that
resulted in prolonged spillages of 4.5 hours in August,a 20 hour spill in
September, and a 36 hour spill on the 9th of November.
In 2009 the accolade of a blue flag beach standard for
Cefn Sidan was not awarded.
As a result of the November 2008 recorded spillages, Dr Lewis
Keil was invited to attend the November19th. 2008 Pembrey & Burry Port Town
Council meeting.
Members informed Dr Keil ,that they were very concerned,
that, there had been eleven recorded spills at the Khymer Canal since January,
especially as the canal is inert, and located in an area used for local events,
and surrounded by properties. These spillages had occurred since the
pumping station was upgraded and before completion of the new development at
Chandlers Yard where there are already problems with the sewage system.
Dr Keil agreed that spillage levels were too high, he stated
that, combined overflows which discharge are normal,but were not anticipated at
the Khymer Canal, as models approved by the Environment Agency, had
predicted one spill a year.
On the 6th of January 2009 Dr Keil, after the
November 2008 meeting, wrote to the Council. In his letter he wrote” I had
advised of the complete refurbishment of the Ashburnham sewage pumping that was
due in summer 2008. Despite this work being undertaken, there were spills in
September, October and November 2008”, he also “advised that it was
difficult to see what else can be done to reduce spills.”
Finally he offers that”In the short term, the designers are
checking the system to see if adjustment of the pump trigger levels can be
altered to reduce the number of the storm spills. If this is not
successful then a very costly alternative,such as piping storm sewage to the
estuary, would be required to solve the problem.
On the 5th of February 2009, a call for a
ministerial meeting on water quality, in the Burry Inlet, calling for action
through the assembly, and Europe, following the disappointing news that the
Blue Flag award, had been withdrawn from Cefn Sidan beach. The loss of the
award had increased local concerns about water treatment, and the impact of
large scale housing developments on the insufficient and over used water
treatment works during periods of heavy rainfall. The local Assembly Member had
arranged to meet the Minister for the Environment on the 11th of February
to express concerns. A meeting with the Member of the European Parliament, had
also called a meeting to discuss the level of concerns of the estuary.
On the 12th of February the then Environment
Agency Wales, reacting to the February the 5th press release, in a
Position Statement offered the following comments “It is important to
know that combined drainage systems such as those in Burry Port pumping station
are deliberately designed to allow discharges to the sea or rivers under
certain controlled conditions.
During heavy rainfall, the pumps cannot pass forward all the
sewage to the sewage treatment works, and the dilute sewage is allowed to
overflow into the sea or the river. This storm sewage as it is called, is
screened and requires a licence (called a consent), from the Environment Agency
which contains conditions that Dwr Cymru Welsh Water must adhere to.
If the combined drainage system was not able to operate like
this, then under heavy rainfall conditions, it is likely that domestic and residential
properties, would flood with sewage.”
Setting aside the assertions of the various regulatory
authorities, whose responsibility is to maintain the directives, in reality the
situation cannot be further from the actuality, that, on March the 26th
2015 the European Court ruled that the Government of the United Kingdom was in
breach of the Urban Water Treatment Directive at Llanelli, and Gowerton, and is
awaiting a judgement to be handed down by the Court.
The European Court judgement is the culmination of several
years of investigations, discussions by various lobby groups to determine the
truth behind the observations of many individuals, that all was not well in
terms of fishery expectations, and that the well being of the estuary and the
inlet was far from being healthy.
In May 2017the European Court finally handed down the ruling
but did not fine the United Kingdom for the breach of the Urban Water Treatment
directive.
This case shows how toothless the EU environmental regulations can be.They rely on the local governments to uphold them, local people to report problems and can be soft on breaches. In this case the European Court took almost 10 years to rule on pollution in the Burry Inlet. A ruling of guilt against the UK brought censure but no punishment. Welsh Water cannot afford to install new treatment facilities and are currently digging up central Llanelli to put in new drains to separate ground water drainage from the sewers. Spills continue and the cockles have not recovered. No wonder the people of Llanelli voted to leave the European Union!
