Introduction

SECTION 1.1: INTRODUCTION

Agglomeration: Enfield / Johnstown Bridge Waste Water Works

Licence No: D0131-01

Enfield/Johnstown Bridge Waste Water Treatment Plant (WwTP) was built in 2002 and is operated

and maintained by Meath County Council. The waste water treatment plant was built to serve the

agglomeration of Enfield Co. Meath and Johnstown Co. Kildare. The facility has an engineered design

capacity of 3,500 p.e, the plant is licensed for 3,770 but it continues to provide satisfactory treatment

at a loading of 4,053 p.e.

The WwTP includes screening, grit removal, two extended aeration tanks, phosphorus removal,

sludge thickening, a sludge beltpress and a storm tank. The primary discharge from the WwTP is into

the River Blackwater (Longwood).

The following Annual Environmental Report (AER) has been prepared as per Condition 6.10 of Meath

County Council’s Discharge Licence D0131-01 and includes all information requested under schedule

D of this licence.

SECTION 2.1: FLOW REPORT.

Final Effluent Flow Meter

Due to the hydraulic arrangement at Enfield / Johnstown Bridge WwTP and in particular the

respective levels of the plant, the entire length of the outfall pipeline is regularly flooded by the

adjacent Blackwater River and for this reason it is not possible to install a final effluent flow meter. A

flow meter cannot operate accurately and continuously in these submerged conditions

For the purpose of AER and PRTR calculations, Meath County Council, taking into account losses

through sludge wasting, dewatering etc has estimated the daily final effluent flow to be 95% of the

total daily influent flow recorded at the plant. See SECTION 2.2: INFLUENT AND EFFLUENT FLOW

REPORT.

Comments:

Note 1: An average BOD of 178mg/l, as calculated in Section 2.10, was used to

determine the current p.e loading on the plant.

Note 2: The average daily influent flow used to calculate the current plant loading is

the average of the all the daily influent flows recorded in 2010. See SECTION

2.2 INFLUENT AND EFFLUENT FLOW REPORT.

Note 3: Annual Mass Influent Flow, calculated in SECTION 2.2 INFLUENT AND

EFFLUENT FLOW REPORT.

Note 4: The current p.e loading at Enfield WwTP for 2011 is approximately 3,051.

SECTION 2.10: SUMMARY REPORT ON CURRENT PLANT LOADING.

In Section 2.9, Meath County Council has used an average BOD result of 178 mg/l to

determine the current plant loading at Enfield WwTP. In 2010 influent results were

determined from grab samples and not 24hr composite samples. As a result, on a few

occasions, grab sampling coincided with supernatant return from the plants PFT (Picket

Fence Thickeners) and hence this resulted in unusually high BOD spikes. For the purpose of

the plant loading calculations Meath County Council has omitted any BOD results over

300mg/l as these results are not characteristic of typical domestic waste water influent and

do not give a true reflection of the plant loading.

Influent at Enfield WwTP is now tested from a 24hr composite sample and as a result the

average BOD up to June 2011 is 134 mg/l. This figure is more representative of domestic

waste water influent and with an average influent flow of 1,366 m3/d (2010), the current p.e

loading at Enfield WwTP for 2011 is approximately 3,051.

Influent results with a BOD less that 300 mg/l

SECTION 4.1: STORM WATER OVERFLOWS IDENTIFICATION AND INSPECTION REPORT

As per Condition 4.12 of this licence an identification and inspection report was conducted and

submitted to the EPA ON June 15th

2010. Over flow has been deemed to be in compliance with

DoEHLG Procedures and Criteria in Relation to Storm Water Overflows but recommendation has been

made to record exact frequency of overflows onsite.

SECTION 4.2: IMPROVEMENTS PROGRAMME

LICENCE CONDITION 5.1: PROGRAMME OF INFRASTRUCTURAL IMPROVEMENTS.

MCC will prepare a programme of infrastructural improvements to maximise the effectiveness and

efficiency of the wastewater works. The programme will be in accordance with the licence Schedule C

Specified Improvements: Reduction in Total Phosphorous concentrations of primary discharge to

0.5mg/l by 01/01/2011.

LICENCE CONDITION 5.2: ASSESSING THE PROGRAMME OF INFRASTRUCTURAL IMPROVEMENTS.

MCC conducted a thorough assessment of infrastructural improvements of all Storm water Overflows

(SWO) associated with the Enfield waste water works and any recommended works will be

undertaken in 2012 subject to available funding

LICENCE CONDITION 5.3: PLAN FOR IMPLEMENTATION OF INFRASTRUCTURAL IMPROVEMENTS.

There were no developments or infrastructural works carried out by Meath County Council during the

AER period 01/01/2010 to 31/12/2010.

LICENCE CONDITION 5.4: PROGRAMME OF MEASURES FOR GATHERING, RECORDING, AND RETENTION OF INFORMATION

As-Constructed drawings and Mechanical & Electrical drawing are available for inspection, centrally at

Navan WwTP. The information includes all the infrastructural components of the waste water works.

SECTION 4.3: DEVELOPMENT/INFRASTRUCTURE WORKS.

There were no developments or infrastructural works carried out by Meath County Council during the

AER period 01/01/2010 to 31/12/2010.

SECTION 5.1: STATEMENT OF MEASURES.

Annual Statement:

Meath County Council will take all reasonable measures to prevent environmental damage. Meath

County Council is also reviewing its environmental liability pollution insurance to ensure the costs of

all remedial actions following an anticipated events, accidents or incidents associated with discharges

or overflows from the waste water works are covered.

SECTION 5.2: ENVIRONMENTAL LIABILITIES AND RISK ASSESSMENT (ELRA) REPORT.

As per condition 7.2.2 of the licence, Meath County Council had prepared a comprehensive

Environmental Liabilities Risk Assessment (ELRA). The assessment was conducted by Rowan

Engineering Consultants Ltd. and was submitted to the EPA on the 27TH

May 2011.
