Question 1 . Provide a status update regarding the proposed Dungloe sewerage scheme upgrading works under the Water Services investment programme 2010-201 2.

Response to question 1

Dungloe/Glenties WWTPs are being progressed as one OB0 contract. The scheme is listed as "contracts to start" on the current Water Services Investment programme. Approval of the contract documents was received from the Department of the Environment at the beginning of 201 1 . Tender notices are to be advertised in the near future. A contractor should be appointed by 201 2 with a construction period o f approximately 24 months.

Response to (i)-(vi)

Ql(i) - Drawing DGWLA/C2(ii) o f the Drawing Schedule shows the location of the proposed Dungloe WWTW and DGWLA/C2(vi) gives its co-ordinates.

Ql(ii) - Drawing DGWLA/C2(iii) shows the indicative layout of the WWTW, however, as the project is being procured under a Design, Build and Operate form o f contract it will be the successful contractor that designs the plant to meet the performance specification. I attach below a table that sets out the final effluent standards as set out in the tender documents. Please note that the tender documents only require the contractor to build a plant to satisfy stage 1 loadings and effluent quality, but also show how his design could be modified to allow stage 2 requirements to be met.

'P Dungloe Sewerage Scheme Oungfoe Wastewater Treatment Plant Part 8 Renott

1. INTRODUCTION

An improved sewerage scheme is proposed for the town of Dungloe in Co.

Donegal to provide collection and treatment of wastewater in the town for the

present and future populations, There Is an existlng sewerage network in the

town and this will be refurblshed where necessary and extended to servlce

additional developments.

At present there 1s a septic tank providing primary treatment to the wastewater

generated in Dungloe. A new treatment plant is requlred to cater for the present

and future population. The proposed wastewater treatment works in Dungloe wlll

Improve the treatment of the town's wastewater by:

(a) Provldlng a wastewater treatment works with a design population

equlvalent of 2,400 to cater for flows and loads from the present and

projected populations In the town.

(b) Refurblshment of the sewerage network where requlred and extending the

network to service new developments,

(c) Connecting outlying devefopments to the sewerage network to reduce the

environmental impacts of discharges from septic tanks. "

3. OUTLINE DESCRIPTION O F THE WORKS

The Works consist of the following elements:- . A proposed Wastewater Treatment Works at Meenmore Townland,

Dungloe, Co. Donegal,

a An outfall pipeline to carry treated effluent from the Wastewater

Treatment Works to the Dungloe River upstream of the existing weir at

Meenmore Townland, Dungloe, Co. Donegal,

=

The Dungloe Wastewater Treatment Works may be procured as a design, bulld

and operate contract. The sewerage network will be procured under separate

traditional contracts.

There Is mixed residential and commercial development proposed at the location

of the existing septic tank and so a new location for the proposed works was

identified. The proposed wastewater treatment works is to be constructed on a new site north of the town, see Drawing No. 20295/PC/Ol. The new treatment

works may be procured under a deslgn/bulld/operate method of procurement.

The design population equivalent for the plant will be 2,400 p e . and lndicatlve

plant layout, sections and elevations are shown on Drawing No. 20295/PC/03.

The Treatment Works will be required to meet the effluent quailty standards as

set out In the Urban Wastewater Treatment Regulations, 2001 and in all current

regulations governing dlscharges to freshwaters.

I).

I t is proposed to discharge the treated effluent from the treatment works to the

Dungloe River, which flows into Dungloe Bay. The following are the effluent

standards to be adopted for the treatment works In Dungloe:

BOD not greater than 25 mg/litre

= SS not greater than 35 mg/iitre

Dungloe Sewerage scheme Dungloe Wastewater Treatment Plant Part 8 Report

4. IMPACT OF THE SCHEME

me design population of the proposed treatment works Is 2,400 p.e. This is less

than the threshold set out In the First Schedule of the 1989 EIA Regulations.

Envlronmental studies have been carried out to assess what mitigation measures

will be requlred for the scheme. An EIS Scoplng Report was produced and it was

decided that a full EIS would not be required

Under the EC (EIA) Amendment Regulations SI 93 of 1999, the planning authorlty

must consider whether the development In an environmentally sensitive area

such as SAC or cSAC would be likely to have a slgnlflcant effect on the

environment,

In order to determine the likely impact of the development, a number of studies

concernlng local habitats, flora and fauna have been carried out. These included

ecological assessments of the Impact of the proposed development on the key

habitats and species in the locality.

At the location of the treatment works, landscaping will be carrled out wlth

suitable plantlng ensurlng that the works merge harrnonlously with the

surrounding area. Small clusters of trees and shrubs will be planted around the

sites to enhance the overall visual appearance. Fast growing trees and shrubs

wlll be provided around the perimeter of the sites. Thls wlll have the effect of

reducing tlwvlslbllity of the works from all directions.

All bulldlngs on the treatment works site wlll be restrlcted to a maximum helght

of 7.0 metres above the existing ground level as shown on Drawing No.

20295/PC/03. All tanks and other process structures shall be buried or partially

buried so that no more than 7.0 metres projects above the finished ground level.

The hardstanding on the site will have a bitumen macadam surface and be kerbed

to form roadways and turning areas.

The main features of the proposed scheme are the provlslon of rellable collection

and treatment facilities for the existing and future resldentlal and comrnerclal

developments in the town of Dungloe which shall enhance the environmental

well-being of the area.
