UTILITY SERVICES INFRASTRUCTURE

Introduction

The proposed Vounog Hill development site is located adjacent to the Vounog Hill/ Wrexham

Road highway south of Penyfford at the intersection with Min Y Ddol.

The proposed residential development comprises of circa 40 dwellings with a mix of two,

three and four bed homes and associated community space.

Refer Appendix A – Proposed Development Site Plan

The scope and occupancy of the proposed development will require the provision of

statutory utility company network connections as part of the planning proposals.

Initial contact has been made and informal liaison undertaken with the respective statutory

utility companies to determine:-

The scope of their existing network distribution apparatus,

Associated considerations and constraints,

Their ability to serve the development.

The following sections of this report detail the finding of the above.

EXISTING UTILITY NETWORKS

In the locality of the proposed development, and specifically within the adjacent highway

zones, there are existing Utility Company distribution supply networks.

A review of their record plans and informal consultation has determined that the scope of

these systems, and is understood to be:-

A 2” CI spur main at the intersection of Vounog Hill and Min Y Ddol.

A 180 PE distribution main with smaller branch sizes serving the properties east of

the proposed site, with a 3” AC routed east towards Blackbrook Farm.

Fire hydrants, normally referenced as FH’ are located are not identified on the DVW

record plans and will be subject to liaison and a record check with North Wales Fire &

Rescue.

Refer to Appendix D – UU Water Record Plan

Sewerage: Welsh Water (WW) Network Sewers, comprising of:-

A 150mm VC (vitrified clay) combined (foul and surface water) sewer routed from the

intersection of Vounog Hill and Min Y Ddol road, flowing north generally along the

line of Vounog Hill highway, connecting to a 250mmVC sewer at the vounog Hill and

Park Lane highway intercection.

A 225mmVC combined sewer routed between the properties on the west side of

Wrexham Road and on the east side of Berwyn Avenue flowing north to Alyn Road,

then west.

Telecommunications: Openreach (OR) Network, comprising of:-

Voice and data cables within interconnecting ducts and chambers in the highway

zones of Vounog Hill, Wrexham Road and Min Y Ddol and other surrounding

highways with specific ducts being:-

o Two lines of cable duct and chamber cableways within the highway zone of

Vounog Hill / Wrexham Road.

o A cable duct and chamber cableway within the highway zone of Min Y Ddol.

7


o A pole located on the corner of Vounog Hill and Min Y Ddol within the verge, with

overhead cables crossing Vounog Hill and Min Y Ddol.

Refer to Appendix F - OR Cable Duct & Chamber Record Plans.

General

The specific location and routes of the existing services, whilst known in general terms from

the respective Utility Company’s record plans, will require to be accurately identified along

their whole route where it is considered that they may impact on proposed works, such as

the creation of vehicle accesses.

It is proposed that this will be achieved at the early design stages, through liaison with the

respective Utility Company, consulting existing records, and the undertaking of specialist

search and survey techniques.

CONSIDERATIONS AND CONSTRAINTS

The existing utility services are primarily located within designated public highway zones and

are secured by the statutory highway status, however where specific network apparatus

extends into private land, these will likely be with formal agreements and/or

easements/wayleaves, including redundant/abandoned cables.

The existence and scope of any formal wayleaves and easements will require reviewing and

agreements reached as appropriate and necessary.

Abandoned utility services in the locality of the proposed construction will need to be located,

identified, its status checked and removed where necessary.

Any private services installations identified, whether unused, redundant or abandoned, will

need to be investigated, decommissioned, isolated and either abandoned or removed as

appropriate, as part of the development planning.

The utility services which may impact on the proposed development site area are:-

A Water main crossing the southern section of the proposed development area,

generally running parallel to Min Y Ddol.

Telecommunication cable duct(s) being potentially close to the back of road verge

against the proposed development’s west boundary.

Telecommunications pole within the verge close to the proposed development’s

south west boundary.

Street lighting columns at back of the road verges of Vounog Hill and Min Y Ddol.

8


The creation of vehicle access from Vounog Hill and Min Y ddol may impact on the existing

line and cover levels of the existing utility cables, pipes, ducts and apparatus crossing the

access, resulting in the cables, pipes and ducts having to be lowered or protected as part of

the Statutory Highway condition in creating the access.

This would be conditional upon:-

Consideration of the position and depth of the utility services;

Formal approval from the respective Utility Company, and

A requirement for diversions, replacements and reinforcement of utility services

affected.

Any change to the access road line and level would likely impact on the following services:-

Electrical LV cables

Lighting columns and associated electrical cables.

Gas main pipes

Water main pipes

Telecommunication cable ducts and voice and data cables contained within.

Street lighting columns and the associated LV cables.

NEW SUPPLIES FOR THE PROPOSED DEVELOPMENT

The proposals for the development have been reviewed as part of this planning statement in

order to be able to determine the utility services demand for the proposed properties

An assessment of the utility services in the vicinity of the existing site has been undertaken.

The scope of the development’s requirement for electric, gas, water, sewerage and

telecommunications are understood to be within the utility network capacities presently

within the surrounding district, and in conjunction with the respective Utility Company

through application and negotiation, their networks can be modified, reinforced and

extended into the proposed development to serve the development and the occupants.

It is anticipated at this stage that the scope of the required utility installations will be:-

9


SPEN Electrical Supply

Informal liaison with SPEN has indicated that the existing HV network local to the site has

the potential capacity to supply the proposed development via a new substation which will be

required to be located within the proposed development site area.

The proposed new substation would be a network apparatus being operated by the supply

network company, with SPEN LV distribution throughout the proposed development and

individual supplies to all properties, street lighting and any other communal requirements.

All properties would be individually metered.

West & Wales Utility Gas Supply

Informal liaison with West & Wales Utility Gas has indicated that the existing LP distribution

network within Vounog Hill would likely need to be reinforced to provide gas for a space

heating, domestic hot water generation and cooking provision.

The reinforcement would likely be the up-sizing of the existing main in the highway zone of

Vounog Hill, from the larger pipework approximately 600 metres north of the site.


Dee Valley Water Supply

Informal liaison with DVW has indicated potentially that the existing mains network

distribution within Vounog Hill could supply the proposed development however this will

need to be subject to a network check before confirmation.


The DVW standard supply arrangement is for 1.0 bar (10 metres head) pressure at the

development site boundary, and whilst the current network operational water pressures in

particular locations may exceed this, it cannot be relied upon as a guarantee available

pressure to the development.

The fire hydrant requirements for fire fighting, within the development area, would be as

determined by North Wales Fire & Rescue.

Welsh Water Sewer Outfall

Informal with WW has indicated that the existing combined sewer within Vounog Hill beyond

Park Lane could be capable of receiving the foul drainage outfall from the proposed

development, however a this would be subject to a system check.

Surface water from the development will be subject to constraint and disposal by either

soak-a-way within the site and/or attenuation prior to any discharge to a drain ditch

employing SuD’s disposal and management requirements.

10


Openreach (OR) Telecommunications

A cable duct connection will be capable of being sought from Openreach’s local existing

cable duct and chamber network in Vounog Hill to a position to suit the development.

The new BT Cable duct connection and network will be capable of carrying voice and data

cables to provide broadband internet to the development, as required by the property

occupants.

Currently, Openreach are advising that in the locality of the proposed development

‘superfast’ broadband is available (i.e. potentially capable of speeds up to 80Mbps download

and 920Mbps upload capability), albeit but subject to individual orders and locations.

The location of the BT ‘enabled exchange/cabinet’ is referenced Caergwrle status ‘Fibre

Enabled’ cabinet 7, technology FTTC, and is approximately 3000 metres south of the

development.

UTILITY REPORT CONSIDERATIONS

This utility supply assessment report is based on the respective Utility Company records and

the statutory requirement for them to provide connections where planning and development

is approved.

The information provided does not replace a requirement for a legal land search to be

undertaken to identify land ownership, covenants, rights of way, wayleaves, easements, and

rights under Acts of Parliament.

The assessment has been undertaken without any on-site surveys and it is understood that

these will be carried out at an early design stage incorporating below ground services

search/identification techniques.
