Private Water Supply Risk Assessment Consultants in Argyll, Highland, Lanarkshire and Renfrewshire 

The ability of an existing or proposed development to abstract water from a river, burn, minor watercourse, aquifer, freshwater loch, lochan or borehole can be assessed by TransTech in order to gain planning consent.


There are three main risks associated with private water supplies all of which can be covered in a single site-specific assessment/report.


These are that the supply is not sufficient to service the proposal, that the water in the supply is not wholesome in terms of its chemical and/or biological constituents and that the wholesomeness of the supply could become compromised by potential contaminants.


To address these risks we evaluate the hydrology within the point of the proposed abstraction, examine the risk from potential contaminants, and where past test results aren't available take and analyse a water sample.


The assessment defines the sufficiency of the proposed supply, the identification of the risks of abstracting from the source and what mitigation including recommended treatment should be put in place to address these.


We have dealt with dozens of water abstraction projects since 2006 and to date have removed the planning condition for 100% of these.


Our private water supply assessment services are limited to Scotland and we cover the whole of Scotland from Argyll, Lochaber, Ardnamurchan and the rest of Highland down to Dumfries and Galloway and the Scottish Borders. We can also carry out assessments on any of the Scottish islands.


The assessments comply with The Water Intended for Human Consumption (Private Water Supplies) (Scotland) Regulations 2017.

Non-means tested grants are available for Private Water Supplies


Grants of up to £800 are available from your local authority to help you improve your private water supply.


The Grant Scheme is non-means tested and you may be eligible for financial assistance if:

  • your home or business is in Scotland and served by a private water supply,
  • the private water supply is the main or sole source of water for human consumption purposes to these premises, and
  • your private water supply is in need of improvement to bring it up to modern standards.

Details about the application process are available from your local authority to which completed forms should be returned.


You will need to provide a detailed estimate of the costs of your proposed improvement works.


If you share your supply with a number of neighbouring premises you may wish to consider making a joint application. A joint application can be submitted in respect of all the premises served by the supply, by you and the other owners or occupiers acting together. In the majority of cases a joint approach is likely to provide the most effective long term solution to improve your water quality.


You should not start any of the improvement works before your application is approved by your local authority. Your local authority must agree that the expenditure is necessary. The cost of improving a private supply can vary hugely and there will be instances where the supply requires work which exceeds the £800 grant. In such cases it will be your responsibility to meet the additional costs. Your local authority can provide information and advice about the Grant Scheme and help you complete the application form.
