Introduction

1.1

Background

BURO HAPPOLD

This Utilities Strategy report has been prepared by Buro Happold as part of the development of the masterplan at Ladyfield, Dumfries for The Crichton Trust.

The report provides an overview of the existing utilities infrastructure and identified any relevant site constraints.

Taking account of the nature of the masterplan, the demand for utilities has been estimated and initial discussions have been held with the incumbent utility companies. The report identifies the anticipated need for on site improvements and off-site reinforcements, based upon initial estimates.

The report identifies certain design criteria and conceptual options for addressing the utility engineering requirements associated with the Masterplan. The utilities covered in this report include: • • • • •

Telecommunications

Existing site constraints

The site is located approximately 2.5km south of Dumfries town centre and covers approximately 20.3 hectares of

grassland in the northern section and an arable field in the southern section. The site is bounded by Glencaple Road

(B725) on the east, Kingholm Road on the west, Kingholm Loaning to the south and housing along Glencaple Avenue to the north.

Figure 1-1 Red line boundary and site location (Map data © Google Earth).

In the southern agricultural area, a row of cottages (Ladyfield Cottages) extends towards the central spine of the site but does not lie within the site boundary. The Crichton is located to the east of the site and the River Nith is approximately 350m to the north and west.

Mature trees are located across the site and the land is given over to mainly pasture and the mature trees. The

topographic data shows the site slopes from east to west, with a ridge that runs through centre of the site on the eastwest axis. A topographical survey from 2001 shows the high point of the site at +29.13 at the south east corner and the low point as +7.66 at the south west corner. The topographic survey is included in Appendix A and shows the range of levels on the existing site.

1.3

Existing Utility Network

The existing utility networks have been sized to serve the existing local areas and provide interconnectivity to the

network as a whole. As an undeveloped site, the existing site does not impose any utility loads and therefore the

demands of the proposed scheme will need to be accommodated within the existing network or reinforcement of the existing network may be needed.

Record information (NRSWA C2) has been obtained and received from each incumbent utility provider for their

respective assets which has been used as a basis for this report, asset record drawings are compiled in Appendix D. As

the utility design develops, each utility company will be required to produce detailed capacity studies of their networks

to ascertain the extent of reinforcement required. The existing utilities drawing from Ashers Associates in 2001 has also been used to inform the location of existing utilities, included in Appendix C.

1.4

Proposed Development

The proposed scheme is a housing-led mixed-use development comprising up to 350 new homes as well as

employment land-use and community facilities, open space, green-blue infrastructure, and associated works. There are no existing buildings on the site and so no demolition works are required. An illustrative masterplan presenting a vision for the site is presented in Appendix B.

The scheme is envisaged to be fully realised in a phased manner over five clusters, for which as the masterplan develops, the utility strategy should be further developed to align with the build programme.

1.5

Methodology

The methodology shown in Figure 1–2 has been followed in submitting predevelopment enquiries regarding the

capacity of the network and obtaining the C3 budget estimate for diversions to establish if any reinforcement works

are required.

The current existing services information has been collated from statutory authority record data received from Groundwise Searches dated 10/08/2022, potable water phasing design drawings from Asher Associates dated 17/04/2016 and historical design drawing from Asher Associates dated 12/04/2001.

Drainage System

Refer to the separate Buro Happold Drainage Impact Assessment report for details of the existing drainage network

and proposed strategy for surface water and foul water drainage.

1.8

Water Supply

1.8.1

Existing Network

Scottish Water asset location search maps indicate the existing site is bounded by the following water main network located along the existing roads: •

160mm HPPE along Glencaple Road on the east

•

4” AC (asbestos-cement) along Glencaple Avenue in the north

•

4” uPVC along Kingholm Road on the west

•

75-160mm HPPE along Kingholm Loaning in the south

The Crichton and the surrounding local area are supplied by a reservoir approximately 1km to the north east of the site. Refer to Figure 1-4 or Appendix D for the Scottish Water asset records.

1.8.2

BURO HAPPOLD

Design Constraints

Asher Associates drawing from 2001 indicates there are potable water mains that cross the site and serve the existing

buildings (Ladyfield Cottages, Ladyfield East, Ladyfield Villas and Ladyfield West). Based on the 2015 drawing these mains are private with proposals to abandon the private supply and connect the remaining buildings directly to

Scottish Water public distribution main along Glencaple Road. The Scottish Water mains extend along the two access roads to Ladyfield East and Ladyfield Cottages. Refer to Appendix D for the drawings showing the private potable water mains.

It is not anticipated that any public potable water distribution mains will need to be diversion as a result of the

proposed scheme.

1.8.3

Demand Assessment

This section details a high-level calculation of average and maximum daily consumption for the proposed masterplan.

The average figure for one housing unit is based on Scottish Water guidance of 0.005 litres per second. The peak is

calculated by applying a multiplication factor of 2.5 on the average figure. The estimated demand is presented in Table 1-1

Table 1-1 Potable water average and peak demands.

1.8.4

Water Supply Strategy

It is proposed to connect to the existing 4” uPVC distribution main at multiple locations, one along Kingholm Road at the south west of the site, one along Kingholm Loaning and a further two along Glencaple Road. New potable water mains from the existing Scottish Water network will be laid to serve the masterplan, with new individual connections serving each cluster terminating at designated internal meter positions. Points of connection would need to be

confirmed with Scottish Water at detailed design stage and Scottish Water will advise on the infrastructure charges when the connection application is submitted for the detailed scheme.

To assess the overall impact of the masterplan on the local water mains network, a pre-development enquiry was submitted to Scottish Water with the demand for 350 units. Scottish Water carried out a capacity review and

confirmed there is currently sufficient capacity in the Terregles Water Treatment Works to serve a development of that size. Scottish water has also undertaken a Strategic Water Impact Assessment for the area and the proposed site was

found to cause no detrimental impact on the network. The water demand was modelled from the 160mm MDPE pipe on Glencaple Road. Refer to Appendix F for Scottish Water letter response.

The general strategy is as follows: •

Water demand is to be reduced through water efficient fixtures and fittings

•

Individual metered connections to Scottish Water network for each building or shared connection

•

All new dwellings and any shared multi-occupancy residential buildings are to be fitted with automatic fire

suppression systems in accordance with the Building Standards Technical Handbook published by the Scottish government.

Greywater harvesting, namely the collection of sinks, dish washers, showers and baths that will be used in w.c flushing, general cleaning, irrigation, etc. Water collected in the storage tanks, following infiltration, is

pumped to an elevated cistern, and fed by gravity to the points of use. Greywater harvesting is proposed for

Clusters 1-3 and will be considered for the Clusters 4-5 where a cost effectiveness can be achieved.

•

Rainwater harvesting storage tanks collect rainwater from rooftops and other hard surfaces for which the

water collected can be used for w.c. flushing, irrigation, clothes washing. In combination with green roofs as

rainwater capture areas, the amount of water harvested will be reduced which results in a less cost-efficient system and difficult to gauge water collection which is for these reasons rainwater harvesting is not proposed.

1.9

Power Supply

1.9.1

Existing Network

Scottish Power (SP) Energy Network record drawing identifies HV (3 x 50 CU 11kV) overhead cables and LV (2 x 50 ABC) overhead cables across the site. This is shown in in Figure 1-5.

Figure 1-5 SP Energy Networks power network.

1.10

Design Constraints

There are no substations within the site boundary, SP Energy Network advised the poles with the overhead cables are

pole mounted transformers. The overhead cables clash with the masterplan and SP Energy expressed a preference for

underground cables with regards to diversion. It is proposed to divert the overhead cables underground, to follow the proposed alignment of the internal roads, see Appendix E. The overhead lines are on a wayleave where SP pay an

annual fee to the site owner. A diversion application and budget estimate was requested from SP, for which they have provided a budget estimate of £270,000 (exclusive of VAT) to diver the SPEN apparatus to allow further development of the land. SP proposals include the removal of existing HV and partial LB overhead lines to be replaced with

underground cables and network substations to maintain the existing connections. Refer to Appendix G for the budget estimate and plan.

1.11

Demand Assessment

The estimated electric peak loads required for the masterplan are presented in Table 1-2. A diversity factor has not been applied to the demand. In consultation with SP Energy Networks, they advised there is capacity within the

existing HV network to accommodate the proposed development and proposed three substations would be needed to support the scheme for a development of 350 units. The substations would need to be located within 250m from the further house to avoid issues with volt drop.

In correspondence with SPEN and based on a 2.36MVA peak load (350 units), 3 substations are proposed at an

approximate cost of £195,000. The maximum size of substation SPEN install is 1000kVA. Regarding the connection cost, SPEN have advised a cost of £1,500 per unit, the approximate connection cost is £525,000.

District Heating

A district heating (DHN) system is proposed for the scheme whereby a district heating network, fed from a centralised energy centre will provide low carbon heat to homes through a network of underground insulated pipes.

The future energy centre will be located within The Crichton for which the current programme for delivery is

18 months. The proposed scheme will connect to the future DHN at a location along Glencaple Road. Refer to

Appendix E for the indicative location, to be coordinated with The Crichton Trust as the design for the energy centre and network develops.

1.14

Telecommunications

1.14.1 Existing Network A desktop search was conducted for all known utility service providers within the local area and Vodafone, BT and Neos have confirmed they have existing infrastructure in the vicinity.

Neos is only located and operates within The Crichton Estate, BT and Vodafone have infrastructure within and around the site.

1.14.2 Mobile Phone Base Stations A search for mobile operator apparatus was conducted, there were no mobile phone base stations or antenna

identified within the site. There are however two masts situated outside of the site. One is a Vodafone mast (ref.

74604) to the north east of the site located in the NHS Mountailhall Treatment Centre. The other is a CTIL mast located

within The Crichton, adjacent to Easterbrook Hall.

1.14.3 Design Considerations Vodafone own and operate an underground route around the west and south of the site. The network follows

Kingholm Road south, continues east on Kingholm Loaning and across the existing roundabout to The Crichton.

BT Openreach own and operate and underground and overhead route network to the north, east and south of the site. BT poles are located along the northern boundary of the site, between the greenfield site and backs of the

residential houses on Glencaple Avenue. The BT network runs along Glencaple Road footway and enters the site on

the east with overhead cables serving the existing Ladyfield Cottages and Ladyfield East. An existing underground BT

duct is located across the eastern part of the site, connecting Low Lodge to Ladyfield East. It is anticipated part of this network will need to be diverted to accommodate the proposed scheme.

1.14.4 Design Objectives To address future technology and business trends there are a number of key criteria that will be considered for the communications infrastructure including: •

No single point of failure, consideration for a diversified network providing resilience and adaptability,

•

Infrastructure for multiple Internet Service Providers (ISP),

Utilities Strategy Copyright © 1976 - 2023 Buro Happold. All rights reserved

•

Infrastructure for tenants and operator/maintainer,

•

Comms designed to meet the demand of end user requirements,

•

Minimised civil engineering works,

•

Co-ordination with other utilities, and

•

Installation phased with the development clusters.

BURO HAPPOLD

1.14.5 Telecoms supply strategy The Crichton has its own fibre network, and an ongoing 5G research project. Refer to Appendix D for The Crichton’s fibre network. The local council operate an IT department and data centre on The Crichton in Monreith House for

which there are plans for the council to move off site in early 2023. The data centre is well connected and provides an opportunity for the proposed masterplan. An indicative connection from this data centre across Glencaple Road and

connecting to the scheme is proposed.

5G offers improved reliability, higher efficiency, and security. It also offers scalable capabilities for the future and

flexibility to the masterplan. Local coverage of 5G will need to be assessed with the mobile network operators to

determine their capacity in the area and look at options for improving the coverage if it is lacking.

BT Openreach

The proposed BT ductway infrastructure route will be taken from one primary connection to the existing BT

infrastructure. The connection will be taken from the existing supply along Glencaple Road. The proposed connection is an indicative route of supply based on the assumption that this is the most appropriate route from the nearest

Openreach exchanges to supply the masterplan. Detailed site investigations to establish precise locations would be required along with BT undertaking their own study to assess the optimum route for the new fibre optic network connection.

Vodafone The proposed Vodafone ductway infrastructure route will be taken from one primary connection to the existing

Vodafone infrastructure. The connection will be taken from the existing supply along Kingholm Road. Vodafone will need to confirm they have network capacity within the area to serve the masterplan.

Dear J Craven,

Ladyfield, Glencaple Road, Dumfries, DG1 4TQ Pre-Development Enquiry Application – Network Assessment Required Our Reference: DSCAS-0074390-98G Thank you for your recent application regarding the above proposed development. Please note our reference number above, which should be quoted on all future correspondence.

Capacity Assessment Number of Housing Units reviewed: 350 Scottish Water has carried out a Capacity review and we can confirm the following:  There is currently sufficient capacity in the Terregles Water Treatment Works to service your development.  There is currently sufficient capacity in the Troqueer Waste Water Treatment works to service your development.

Network Assessment Further studies are required to be carried out to determine if our existing sewer network can adequately service the demands of your development or if any mitigation/enhancement work is necessary.

Wastewater: A Drainage Impact Assessment (DIA) is required for a development of this size.

A Network Assessment will be required to establish if there is sufficient capacity within the existing infrastructure to accommodate the demands from your development.

Scottish Water has undertaken a Strategic Drainage Assessment for this area in Year 2019. Your site was included. There may have been significant changes during this time

SW Public General

period and therefore a review of the model and the results will be required to determine if further modelling is required.

A member of our Network Impact Assessment Team will contact you in 5 working days to discuss the above.

If you have any questions in relation to the network assessment, please contact us via our portal or at NIAT@scottishwater.co.uk Scottish Water is committed to assisting development in Scotland and has funding under our current investment period to upgrade our water and waste water treatment works however our regulations from the Scottish Executive for our current investment programme state that should your development require Scottish Water networks to be upgraded this cost will have to be met by the developer; Scottish Water may contribute towards the cost of these works, including the required study, via Reasonable Cost Contribution regulations.

Please Note  This response is valid for 12 months from the date above and may be subject to further review  Water: Scottish Water has undertaken a Strategic Water Impact Assessment for this area and this proposed site was found to cause no detrimental impact on the network. The study shows that the submitted proposed demand for flow from your site is acceptable. Water demand has been modelled from the 160mm MDPE pipe on Glencaple Road (B725). This site can proceed if the aforementioned modelling parameters are adhered to.

General Note Please be advised that Scottish Water will only accept surface water into the combined network under exceptional circumstances. In the consideration of any development, if due diligence has been carried out in fully investigating the available options for surface water drainage and if any of these options is subsequently deemed unreasonable to pursue, the remaining alternative options can then be considered for approval to allow the development to proceed.

Scottish Water's current minimum level of service for water pressure is 1.0 bar or 10m head in the public main. Any property which cannot be adequately serviced using this pressure may require private pumping arrangements installed, subject to compliance with the current water byelaws.

Scottish Water is unable to reserve capacity and connections to the water & wastewater networks can only be granted on a first come first served basis. For this reason, we may have to review our ability to serve the development on receipt of an application to connect.

I trust the above is acceptable however if you require any further information regarding this matter please contact me on 0800 389 0379 or via the e-mail address below.

Yours sincerely SW Public General
