Executive Summary:

Dungarvan Town is located on the estuary of the Colligan River and has a population of circa 9,000

persons as well as various commercial activities. There are no wet industries, with the main

industries being pharmaceutical processing. The current total population equivalent of the

agglomeration is estimated at 16,500.

Dungarvan and environs has a modern sewerage scheme, with a treatment plant located at

Ballinacourty (25,000 p.e.) capacity, which is operational since 2007. Wastewater is collected in a

number of catchments in Dungarvan and is pumped from these catchments to the main pump

station in Shandon from where it is pumped to the new waste water treatment plant in

Ballinacourty. Waste water is delivered to Ballinacourty from Dungarvan town via two rising mains

of over 6km length each. There is also a series of small catchments in the Ballinacourty / Clonea that

are pumped to the WWTP. Each pump station in the network has stormwater overflow facilities

which operate in storm conditions, when the forward pumping capacity of the stations is exceeded.

The WWTP is operated by Veolia who are contracted to operate and maintain the WWTP for a 20

year period.

The Licence required that SW2 and SW3 be upgraded by 1st November 2011 so as to be Emergency

Overflows only. As outlined in the 2010 AER, these overflows are designed as Storm Water

Overflows and cannot be converted to Emergency Overflows without a major redesign of the

network and a large capital investment. This is not achievable in the short term.

The Licence also required that SW16, SW17, SW18 and SW19 be upgraded by 1st November 2011 to

ensure that they complied with the DoEHLG’s ‘Procedures and Criteria in relation to Storm Water

Overflows, 1995’. Again, this is not achievable in the short term. The same issue regarding the

necessary redesign and upgrade of the overall Dungarvan network applies for these and the solution

is longer term and expensive. It is intended to carry out some investigative work in 2013.

The Ballinroad WWTP was replaced by a new pumping station in September 2011 and the discharge

from SW20 has now been discontinued. The full decommissioning of the plant will take place in

2013.

1. Introduction

1.1 Licence Register Number:

D0017-01

1.2 Name:

Dungarvan Agglomeration and Waste Water Treatment Plant

1.3 Site Location:

The Wastewater Treatment Plant is located at Ballinacourty, Dungarvan, Co. Waterford.

The co-ordinates for the plant are 230500E, 092150N

1.4 Description of activities at the site:

The Dungarvan Waste Water Treatment Plant located at Ballinacourty, commenced operation in July

2007 and is designed to serve a population equivalent of 25,000. The plant was procured under a

DBO contract and the management of the facility is contracted to Veolia Water by Waterford County

Council.

The Ballinacourty Waste Water Treatment Plant treats domestic, commercial and industrial effluent

from Dungarvan Town and the Ballinacourty and Clonea catchment areas. Wastewater is transferred

to the plant via twin rising mains from Shandon Pumping Station in Dungarvan Town and via a single

rising main from the Ballinacourty and Clonea areas. Waste water in the Ballinroad area was

originally treated at its own WWTP but the effluent is now conveyed to Ballinacourty WWTP, as

stipulated in the waste water discharge licence of 2009. This change in operation commenced in

September 2011. The existing secondary treatment plant at Ballinroad is due to be fully

decommissioned in 2013.

Primary and Secondary treatment of waste water at Ballinacourty is achieved by screening and grit

removal at the inlet works, settlement, secondary biological treatment (activated sludge),

clarification and sludge removal. The sludge treatment process involves dewatering and thermal

drying on site to produce a final product which meets the requirements for use in agriculture. The

treatment plant is designed to treat sludge for a population equivalent of approximately 75,000. This

figure accommodates sludges imported for treatment, which includes dewatered, belt pressed,

aerobic and septic tank sludges. Due to difficulties experienced with the thermal sludge treatment of

7

sludge arisings, lime stabilisation and land spreading was carried out for ten months in 2012.

However due to Planning difficulties with the lime stabilisation site, all sludge is now composted and

land spread.

(SW1) from Ballinacourty WWTP is via an outfall pipe and diffuser into the outskirts of Dungarvan

Harbour, off Ballinacourty Point. The secondary discharge point (SW20) is from the Ballinroad WWTP

into the Colligan Estuary. This discharge was discontinued by the 1st November 2011, in accordance

with the licence requirements.

1.5 Company Environmental Policy (where available):

Waterford County Council is committed to environmental protection and improvement as part of its

role in Local Government and its statutory obligations. It does not have a specific environmental

policy as all such policies are included in the Councils Strategic plan, but not in a format suitable for

extract to this document.

1.6 Company Organisational Chart for Environmental Management:

The organisational structure was developed in 2013. Waterford County Council has divided the

Water Services Operations & Maintenance Team into three relevant individual teams namely;

• the Waste Water Team,

• the Pollution Control and River Basin District Team and

• the Drinking Water Quality & Supply Team.

All of the above listed team members have duties in other areas of work under the umbrella of

Water Services Operations & Maintenance.

2.1 Monthly Influent Monitoring:

Influent Monitoring was carried out monthly in accordance with the requirements of Condition 4.15 of

the licence.

Source: Operator PMS Reports

2.2 Discharges from the Agglomeration:

All licensed parameters are included in the monitoring programme (under Schedule B of the Licence) and

monitoring results are complete for 2012. Metal and Organic Compounds were not analysed in 2012, as

there were not any issues in 2011 sample results.

Faecal Coliforms, Escherichia coli and Intestinal enterococci were monitored monthly in accordance with

the licence.

The receiving water body for the discharge from the Dungarvan WWTP is designated as a Bathing Water

approximately 2km north of SW1 at Clonea Beach. This beach retained its Blue Flag Status in 2012 and

2013. Thus, the bathing waters at Clonea were not adversely impacted by the discharge from the

Dungarvan WWTP. This is the only designation on the receiving waters.

It was noted in the 2011 AER that the ELV of 10mg/l for TON was exceeded on two occasions, {January &

July}. There was no exceedance in 2012, thus indicating that the 2011 exceedances were of an isolated

nature. There are no requirements to upgrade the plant. The matter will continue to be monitored.

There are 5 No. WPA Licensed Activities in Dungarvan. Of these, two relate to a pharmaceutical company,

one relates to a mart, one relates to a petrol station and one relates to a hotel. The petrol station and

hotel discharge domestic-type wastewater only and there is no evidence of impact on the WWTP from

these facilities in 2012 or heretofore. The mart has a licence to discharge 25m³/day of wash waters from

their operation (one day per week) as well as domestic effluent from the facility. There has been no

impact noted on the WWTP in 2012 or heretofore. The discharges from the Glaxo Smithkline sites are

largely domestic-type because the plants are producing finished products only and are not wet processes.

Their licence sets typical discharge parameters to sewers with additional limits for Copper, Zinc,

10

Sulphates, Chlorides, OFGs, Surfactants and Phenols. Their monthly analyses and annual environmental

reports show satisfactory compliance with the discharge licences. There has been no evidence of impacts

from their discharges on the WWTP in 2012 or heretofore.

As can be seen from Table 2.3.1, the average removal efficiency for COD is 87.75%, for BOD is 97.03% and

for Suspended Solids is 93.88%. These rates of removal show that the Dungarvan WWTP is performing

well and treating the effluent load effectively.

The removal efficiency for Total Nitrogen is 51.63% and for Total Phosphorous is 43.39%. These results

indicate that while the plant is operating at its current capacity that Nitrogen and Phosphorous removal is

adequate to meet the requirements of this licence. Given that the plant is operating at circa 66% of the

design capacity, these N and P removal efficiencies indicate that the plant is performing well on these

processes.

12

2.4 Treatment Capacity Report:

The Dungarvan WWTP has a design capacity of 25,000 population equivalent. This translates to a

hydraulic capacity of 15,000m³ (3 DWF) and 1,500kgs of BOD. The current population equivalent as

calculated by the PRTR tool is 17,565. This equates to 70.26% of the design capacity. The average daily

flow into the WWTP was 8,853m³. This equates to 59.0% of the design capacity. The average daily BOD

load in the influent to the WWTP was 1,052kg/day. This equates to 70.1% of the design capacity.

As can be seen from the foregoing, there is currently sufficient capacity left in the plant to ensure that

there is no environmental risk posed to the receiving waters with the current loading on the plant. It is

extremely unlikely that the loading will increase to the point of being a risk in the next three years.

2.5 Ambient Monitoring Report:

Schedule D of the licence requires: “Summary report on ambient water quality of Colligan Estuary and

Dungarvan Harbour pursuant to the requirements of the Shellfish Directive (2006/113/EC).”

This report is provided under Section 6.3 Shellfish Impact Assessment Report of this report.

2.6 Data Collection and Reporting Requirements under the Urban Waste Water

Treatment Directive:

Data collection for Urban Waste Water Treatment returns for Dungarvan has been prepared and

uploading via the EDEN on-line system. The on-line WWTP database for Waterford has been updated with

respect to WWTP details and complaints for all WWTPs including Dungarvan. This was completed in

advance of the closing date of 26th February 2013.

2.7 Pollutant Release and Transfer Register (PTRR) – Report for 2012:

A Pollutant Release and Transfer Register (PRTR) Report has been prepared for 2012. It was prepared in

conformance with the Agency’s guidelines for the PRTR. The influent monitoring data and waste arisings

data were utilised to complete the PRTR calculation tool. Priority and hazardous substances have been

estimated by the use of this PRTR calculation tool. The report was uploaded through the EPA’s on-line

system on 26th

February 2013. The relevant pages from the uploaded PRTR are included in Appendix B of

this report.

There was a total of 3,186,530m³ of treated effluent discharged from the WWTP in 2012 with fugitive

emissions of 58,209m³ as a result of stormwater overflows from the plant. There were no releases to

sewers or other wastewater networks nor any releases to lands from the WWTP. There was on-site

treatment of sludges which were then transported off-site for lime stabilisation / composting and land

spreading. There were off-site transfers of grit and screenings also.

There was a significant increase in discharged treated effluent from 2011, this increase can be quantified

as approximately 52%, which can be attributed to the exceptionally wet summer, and the additional

incoming volume from Ballinroad.

14

2.8 Pollutant Release and Transfer Register (PTRR) – Report for 2013:

Since the PRTR report for 2012 was carried out using the EPA’s calculation tool and PRTR template, there

is no requirement for the Council to submit proposals for 2013.

3. Operational Reports Summary

3.3 Agency Monitoring and Enforcement:

As per the 2011 AER; “A site visit and audit was carried out by the Agency on November 24th 2011. The

Council awaits the report on the audit and will address the audit and any issues/recommendations in the

2012 AER for Dungarvan.”

In addition an Audit was undertaken on 23rd October 2012.

Emission sampling and analysis carried out by the Agency is contained in Appendix A.

The 2011 Audit refers to:

Flow Meter

2.6 The flow recorder is not maintained. Please outline why no maintenance is necessary.

Maintenance of said meter is undertaken since the Audit.

Notifications, Records & Reports

6.1 Since the last audit, all discharges from the waste water works have not complied with the Emission

Limit Values as set out in Schedule A of the Licence (subject to condition 2 of the licence).

6.2 There have been notifiable incidents since the last audit – Total Oxidised Nitrogen exceedances from

Jan - July 2011.

6.3 The incident was not reported to the EPA. Please review EPA incident notification guidance

(attached).

These matters were addressed in the 2011 AER.

The 2012 Audit refers to:

The 2012 Audit did not highlight any matters that were in need of corrective action.

A sample was taken during the Audit, the results of which are provided in Appendix A.

4. Infrastructural Assessments and Programme of Improvements

4.1 Storm water overflow identification and inspection report:

“4.12.1 The licensee shall, prior to the date for submission of the second AER (required under Condition

6.12), carry out an investigation for the identification and assessment of storm water overflows. A report

on the storm water overflows shall be submitted to the Agency as part of the second AER. The assessment

shall include a determination of compliance with the criteria for storm water overflows, as set out in the

DoEHLG ‘Procedures and Criteria in Relation to Storm Water Overflows’, 1995 and any other guidance as

may be specified by the Agency.”

Report:

An assessment of the overflows was carried out in 2010 and included in the AER for 2010, as required by

the Licence. There is likely to be a significant redesign of the entire Dungarvan sewerage network to

enable all of the secondary discharge points to meet the licence requirements. The cost for these works is

likely to be very high and the timeframe for completing them would be in the medium term rather than

the short term.

It is intended to carry out an initial detailed assessment of the existing network in 2013, vis-a-vis the

requirements set out in this licence. This will then enable a programme of works to be drafted and cost

estimates produced. Given the likely high cost of any improvement programme, it is probable that such

works will need to be funded under the Water Services Investment Programme. The AER for 2013 will

include an update on the status of the Storm Water Overflows in Dungarvan.

4.2 Report on progress made and proposals being developed to meet the

improvement programme requirements:

4.2.1 Summary of Improvement Programme:

Licence Condition 5.1: The licensee shall, as a part of the second AER (required under Condition 6.12),

prepare and submit to the Agency a programme of infrastructural improvements to maximise the

effectiveness and efficiency of the waste water works in order to:

a) achieve improvements in the quality of all discharges from the works; The WWTP is new,

commissioned in 2007. There are no proposals for improvement as it is showing compliance with

the licence.

b) meet the emission limit values specified in Schedule A: Discharges, of this licence;

Schedule A1 relates to the treatment plant, and our compliance level is shown in Table 2.2.1 of

this report. There were no compliance issues in 2012.

Schedule A2 is for a discharge that was discontinued in September 2011 in accordance with the

requirements of Schedule A3.

Schedule A4 does not have ELVS associated with the discharge points.

c) give effect to Regulation 2 of the Waste Water Discharge (Authorisation) Regulations 2007 (S.I.

No. 684 of 2007); Section 2 of S.I.684 is a statement of the purpose of the said regulations and is

quite general. It is the Council’s opinion that there are no works currently required to give effect

to this regulation.

d) reduce Total Nitrogen loadings in the discharge to the maximum practicable extent: The nitrogen

removal from the existing plant is more effective than expected from a plant of its type. The

ability of the plant to maintain the licence ELV of TON is not expected to continue when the load

on the plant begins to approach the design capacity of the WWTP (25,000 p.e.). Compliance has

been achieved in 2012 as a result of the plant’s current operating parameters and loading. It is

recommended that further monitoring of loading and TON concentration in the discharge be

carried out and, if and when necessary, a programme of works can be prepared to upgrade the

WWTP. It is anticipated that the loading from the agglomeration will not alter significantly in the

short-term as residential development in the town has virtually stopped.

e) meet the obligations of Condition 1.7. This refers to treatment capacity at the WWTP and this is

currently within capacity on the principal determinant of biological loading. The Plant has a design

capacity of 25,000 p.e., which is equivalent to 1,500Kg of BOD per day for the year 2022. The

plant was constructed with a design capacity equal to the ultimate requirement for the year 2022.

The current average daily loading to the plant, as per tables on the mass loadings Table 2.3.1 of

this report is 1,052 kgs/day of BOD. The plant is operating at approximately 70.10% of its ultimate

capacity.

4.2.2 Update of Improvement Programme Report:

Report on progress made and proposals being developed to meet the improvement programme

requirements namely those set out in Schedule C of the licence. This summary report shall provide detail

on all measures proposed and undertaken under Water Services Investment Programme for

agglomeration, including progress reports on infrastructural works and a statement of compliance with

timeframes set out in this licence.

4.2.2.1 Schedule C of the licence - C.1 Improvement Programme for Primary Discharge

4.2.2.2 Schedule C of the licence - C.2 Improvement Programme for Secondary Discharge

Specified Improvement: Implement a programme of works to ensure SW2 and SW3 only discharge in the

event of an emergency, that is, during pump failure and/or power failure at the associated pumping

station.

Report: SW2 is the storm overflow from Shandon Pump Station. Dungarvan sewerage scheme comprises

a number of sub catchments each delivering to individual pump stations, from where a multiple of Dry

Weather flow is pumped forward in the network until the waste water arrives at Shandon Pump Station.

Each pump station has an overflow facility that is reached when rainfall invades the network and forward

flows are at their limit. These pump stations act as storm water overflow facilities. Shandon pump station

has its own contributing catchment as well as the pumped inputs from the other peripheral stations.

SW2 is the main pump station pumping to the Waste Water Treatment Plant. Its pumping capacity, via

two rising mains is 650m3 per hour to the plant. Any flows into the station in excess of this are overflowed

via a screen to a storm well and subsequently discharged by pumping to the Colligan Estuary.

This discharge would comply with Formula A discharges to non sensitive areas according to the DoECLG‘s

‘Procedures and Criteria in relation to Storm Water Overflows, 1995’. Using a population of 9,000 with a

domestic contribution of 200litres/day and an industrial loading of 400m3 per day, Formula A flows are

calculated as 9,000x0.200 + 1.36x9,000 + 2x400 = 14,840m3/day = 618m

3/hr. This is less than the 650m

3

pumping capacity of the pump station.

Discharge at SW3: This discharge is also a storm water overflow. The pump station is designed to pump

forward multiple times the dry weather flow. The capacity of the pumps is up to 230m3 hour forward via

the network to Shandon station. The contributing catchment population is not calculated so the

compliance of the Storm overflow threshold against Formula A flows is not available. Given the design

philosophy adopted for this new station, it is quite likely compliant, as the design was carried out using a

computer simulation model.

Discontinuation of SW2 and SW3: Both these discharge points are storm overflows as well as pump

stations. Elimination of these discharges will require a complete re-design of the collection system, the

pump stations and the Waste Water Treatment Plant. The nature and extent of the work involved could

21

not be implemented by the local authority under its own finances and would have to be put forward

under the WSIP (Water Services Investment Programme). The current WSIP programme is 2010 to 2013

and the required works for planning are not in this programme. The next WSIP will be under the control

of Irish Water, and the format for this new investment programme is not yet available to Local

Authorities. Therefore Waterford County Council can not establish the funding time lines for these works.

An extensive design and modelling of the network must then be carried out to evaluate the performance

of the storm overflows and to then agree with the Agency as to the appropriate direction to take.

Currently this design/ planning has to be carried out as a scheme “under planning” under the Water

Services Investment Programme (WSIP), due to the size of the design task and the implications for works.

If the scheme is deemed to require from the planning stage to stop discharges at SW2 and SW3, the

whole of Dungarvan Sewerage scheme has to go forward for Planning and design and this will include the

New Waste water treatment plant. A similar and smaller agglomeration of Tramore is currently at

planning stage for network improvements, including reducing Storm water overflows. This scheme is

currently estimated to cost €11m. Given the larger network of Dungarvan and its layout, the likely costs of

such measures would exceed €20m.

Condition 5.6 requires that SW2 and SW3 only discharge in the event of an emergency in after 1st

November 2011. As clearly outlined above, this is a very complex task that involves more than simply

increasing storage at the two pump stations. The necessary storage volumes would not be economical or

practical. The only possible solution is the network upgrade outlined above. This is not feasible within any

short to medium timeframe and, therefore, this licence condition cannot be met by Waterford County

Council.

However, it should be noted that these Discharges were not intended to work as emergency overflows

only and the Dungarvan network that was upgraded in 2004/2005 was designed with these overflows to

act as Stormwater Overflows which complied with the DoECLG’s ‘Procedures and Criteria in relation to

Storm Water Overflows, 1995’. It is possible that the Council may seek a Technical Amendment to this

licence condition in the future.

4.2.2.3 Schedule C of the licence - C.3 Improvement Programme for Storm Water Overflows

Specified Improvement:

Upgrading of sewer network, as required, to ensure Storm Water Overflows comply with the criteria

outlined in the DoEHLG’s ‘Procedures and Criteria in relation to Storm Water Overflows, 1995’ for SW16,

SW17, SW18 and SW19. These improvements are to be made by 1st

November 2011.

Report: The specified date for these works has not been met. A full assessment of the Dungarvan network

needs to be made to see whether or not these Storm Water Overflows comply with the guidance or not.

This has not yet been prepared. If they are not in compliance with the guidance, then a programme of

works is likely to be required to upgrade the full Dungarvan network to ensure the overflows do meet the

requirements of the guidelines. As outlined in the Section 4.2.2.2 on SW2 and SW3, this is a very

significant body of work that will be expensive and will not be in place in the short-to-medium term

future.

4.2.2.4 Schedule A of the licence - A.3 Discharges to be discontinued.

This discharge was discontinued as per the licence requirements.

5. Environmental Liability and Financial Provisions

5.1 Statement of Measures:

7.2.1 The licensee shall as part of the AER provide an annual statement as to the measures taken or

adopted in relation to the prevention of environmental damage, and the financial provisions in place in

relation to the underwriting of costs for remedial actions following anticipated events (including closure)

or accidents/incidents, as may be associated with discharges or overflows from the waste water works.

The statement of measures and assessment of risks associated with Dungarvan WWTP is contained in the

ELRA issued with the 2010 AER for this licence, as far as it is possible to ascertain these risks. On the issue

of underwriting costs: Waterford Co. Council has a long term contract in place for the operation of the

waste water treatment plant and is committed to financing same. Local authorities are state bodies and

dependant on Government for funding. Financial provisions for remedial works, if required, would come

from current annual revenue funds, as far as these would be available.

As from 1st January 2013, Irish Water will be the responsible financing authority for this DBO Contract.

5.2 Environmental Liabilities Risk Assessment:

7.2.2 The licensee shall arrange for the completion, by an independent and appropriately qualified

consultant, of a comprehensive and fully costed Environmental Liabilities Risk Assessment (ELRA) to

address the liabilities from present or planned discharges. A report on this assessment shall be submitted

to the Agency for agreement as part of the second AER (required under Condition 6.12). The ELRA shall be

reviewed as necessary to reflect any significant change to the volume or character of effluent discharged,

and in any case every three years following initial agreement (the results of the review shall be notified as

part of the AER).

The 2010 AER contained a copy of the ELRA for the Dungarvan Agglomeration. There have been no

significant changes to the volume or character of effluent discharged since that assessment was prepared,

nor are there any expected changes to the effluent discharged. Thus, there has been no requirement to

provide a new ELRA for the 2012 AER. The next revision of the ELRA will be due in 2013 and reported on

in the 2013 AER, unless otherwise recommended by the Agency.

This assessment was prepared and included in the 2010 AER, as required under the Condition 5.8. It did

not appear to show any significant issues with E coli and in 2010, all sampling showed that the shellfish in

Dungarvan were compliant with the guidelines.

The monitoring results for 2012 are shown in the Table below received from the SFPA and the DoECLG.

Appendix C: Responses to the Agency’s Assessment of the 2011 AER.

C.1 Treatment Capacity Report:

“Explain differences in the number of reported incidents between database and AER” – “Review

Incident classification”

With reference to Section 2.4 Environmental Incidents and Complaints of the 2011 AER;

“There were two exceedences of ELVs that are deemed non-compliant in accordance with Condition 2

of the Licence. These were not notified to the Agency owing to a misunderstanding with respect to

when they were to be reported. It was believed that the overall number of exceedences was still less

than outlined in Condition 2 and that the results would be notified in the AER for 2011. Such non-

compliances will be notified to the Agency as soon as possible should they occur in the future.”

This section outlines how the error occurred due to a misinterpretation of the licence and that this

was now clarified; “Such non-compliances will be notified to the Agency as soon as possible should

they occur in the future.”

C.2 Improvement Programme Progress:

“Is the Improvement Programme on time with the Schedule A3 and C dates? - If no, what is the

scheduled completion date?”

“upgrade of SW2 & SW3 to emergency overflow due 01/11/2011. No date is given and WCC may

seek a technical amendment in this respect”

Agreed, Waterford County Council will seek a Technical Amendment to this requirement once the

solution has been defined and funding provision / funding timelines identified.

C.3 Assessment of Licence:

“Is there a need to advise the EPA for consideration of a technical amendment/review to the licence?

- List reason - Eg. Additional SWO identified - IP dates not being met and will not be met in the short-

term”

“From the EPA assessment of the AER, is there a need to request/advise the EPA of any modifications

to the existing WWDL? - List reason - Eg. Additional SWO identified, failure to complete specified

works within date - IP dates not being met and will not be met in the short-term”

It has not yet been established the extent of these works, the associated costs and the funding

streams required to provide such works.

45

C.4 Report Statistics:

“Has the Improvement Programme passed or will pass the Schedule A3 & C Dates?– What is the

Estimated completion date? - upgrade of SW2 & SW3 to emergency overflow due 01/11/2011. No

date is given and WCC may seek a technical amendment in this respect”

Agreed, Waterford County Council will seek a Technical Amendment to this requirement once the

solution has been defined and funding provision / funding timelines identified.
