1 Introduction

1.1.1 In support of Chapter 10 (Volume 1) of the Design Manual for Roads and Bridges (DMRB) Stage 3 Environmental Impact Assessment (EIA) report; this appendix presents the baseline detail of groundwater abstractions and private water supplies (PWS) that were identified within the study area for Project 8 - Dalwhinnie to Crubenmore of the A9 Dualling Programme (hereafter referred to as the Proposed Scheme) and records the consultation undertaken regarding them.

1.1.2 Potential impacts are assessed and mitigation measures identified (if required) in Chapter 10 (Volume 1), while additional abstractions related to surface water and hydropower via the Cuaich aqueduct through Dalwhinnie are identified and assessed in Chapter 11 (Volume 1) where necessary. Natural springs and flushes present in the study area but not identified as existing PWS sources are considered in the context of the potential groundwater dependent terrestrial ecosystem (GWDTE) assessment in Chapter 10 (Volume 1) and Appendix 10.2 (Volume 2).

2 Approach and Methods

2.1.1 The assessment related to groundwater abstractions and PWS covered a study area extending to 850m from the temporary and permanent works boundaries of the Proposed Scheme, which was considered to correspond to the minimum study area applied for groundwater abstractions under The Water Environment (Controlled Activities) (Scotland) Regulations 2011 (CAR).

2.1.2 In order to identify these features, consultation was undertaken with The Highland Council (THC), Scottish Environment Protection Agency (SEPA) and HighWater (Scotland) Ltd. Additional information regarding the source, location, type and use of any such features present was then obtained through private property/ landowner consultation questionnaires, public exhibitions and/ or site walkovers. Additional consultation regarding some supplies may be required as part of pre-construction activities as identified in Chapter 10 (Volume 1).

3 Baseline Conditions

3.1.1 Based on the consultations undertaken and questionnaire responses/ feedback received, one groundwater abstraction (comprising three shallow wells) and two PWS source locations were identified within the study area, supplying properties in Dalwhinnie, Cuaich and Crubenmore.

3.1.2 The approximate locations of the abstractions and PWS sources and supplied properties are illustrated in Drawing 10.21 to 10.29 (Volume 3) with photographs and questionnaire feedback from private properties/ landowners, summarised in Annex 10.3.1. The collective known details and status of each feature identified are summarised in Table 1.

3.1.3 The sensitivity of each feature has been assigned based on the criteria within Table 10-4 in Chapter 10 (Volume 1) and the number of properties served.

Dalwhinnie Water Treatment Works, Dalwhinnie, PH19 1AB

Response Received: 17 November 2016 (email)

From: Jim Briggs, Scottish Water

Address: 31 Henderson Drive, Inverness, IV1 1TR

Abstraction/ PWS Reference: ABS 8.5

Abstraction/ PWS Address: Dalwhinnie Water Treatment Works, Dalwhinnie, PH19 1AB

Q1. Is your water sourced from a private supply or abstraction, such as a well, a spring or a tank?

Shallow infiltration chambers adjacent to River Truim

Q2. Can you confirm the location of the supply, well, spring or tank and any associated pipework? If so, could you provide a plan and/ or photograph?

Plan of water treatment works and intakes attached

Q3. (If it is a spring), do you know the exact location of the spring?

Not a spring

Q4. (If it is a well), how deep is the well?

Approximately 3m

Q5. (If it is a tank), do you know the details, storage capacity and dimensions of the tank?

Not a tank

Q6. How old is the supply?

1970

Q7. How good is the quality of the water supply?

Good quality most of the time, provided no disturbance in river

Q8. Please give a general description of the water (i.e. is it clear, murky)

Clear – full analysis is available from our Process Team if required

Q9. Have you ever noticed any unusual smells off the water/ coming from the supply? If so, please provide a brief description and time of year it occurred.

No

Q10. Has the water ever tasted funny (i.e. tasted off, tasted salty)? If so, please provide a brief description and time of year it occurred.

No

Q11. How good is the quantity of the water supply? Does the water run out in dry periods or fluctuate at certain times or seasons?

In dry periods one of the three wells ceases to produce

Q12. How is the water conveyed (carried) to your house/ field/ reservoir – do you know the location of the supply network (if relevant)?

Water is pumped from chambers to our water treatment works, where it is disinfected, pH adjusted, then pumped again to a remote clear water holiding tank. From there, it gravitates back to the village of Dalwhinnie, the Distillery (domestic only) and visitor centre.

Q13. Does this supply only service your house or does it service other houses/ fields/ reservoirs?

See above

Q14. Is this supply for domestic use and consumption? Or other purposes (please detail)?

For domestic use



Page 2

Q15. Is any treatment provided to the water prior to use?

Chlorination plus pH correction using a limestone contractor

Q16. Approximately what volume/ yield of water is consumer per day?

Various throughout the year, but typically 50 to 100m3/ day

Q17. Has water chemical testing ever been undertaken and if so, how regularly, by who and for what parameters?

Water quality tested continuously

Q18. Can the results of chemical testing (above) undertaken on the supply or abstraction be made available?

Scottish Water Process Team can provide full details if required

Q19. Does your property have a private drainage system (i.e. septic tank)? If so, could you provide details on the location of the tank, discharge arrangement and how often it is emptied?

No

Q20. May we contact you for additional information if necessary?

Yes

Q21. Is there any other information you wish to provide about your water supply?

We have firm plans to upgrade the treatment facilities at Dalwhinnie in this current funding period 2015 to 2021

Additional Information Provided: Plan of Dalwhinnie Water Treatment Works and Wells
