Private water supply risk assessment charges - North Dorset and West Dorset

The Drinking Water Inspectorate has removed all caps on fees and charges associated with undertaking the requirements of the regulations. This is in order to accommodate new requirements set out in the 2018 amendments and allows Authorities to recover their costs.

The 2018 amendmentsrequire that three years of full analysis are carried out before reductions in parameter requirements or sampling frequency can be considered.

The council has set charges as allowed for by the legislation to recover its costs, although it has endeavoured to keep these charges to a minimum. 

The following are approximate charges based on the requirements of the amended regulations:

Risk assessment charges
Action requiredCharge
Risk assessment  Up to £500
Investigation Up to £500
Sampling visit  £20
Sample analysis (Small supply) (Group A) * Approximately £65
Sample analysis (Large supply) (Group A & B) * Approximately £512
Radon** £67.03

* Sample failures may incur additional charges where subsequent confirmation analysis is required

** Only for ground water supplies in areas of increased risk

Administration fees are based on an hourly rate of £30 per hour. Time taken is based on the number of properties on the supply which impacts on the time taken to administer.

PWS Administration Fees
TaskAdmin TimeCost
Pass sample 0.5 hour £15
Fail - Up to 5 properties 1 hour £30
6 to 15 properties 1.25 hours £37.50
16 to 25 properties 1.5 hours £45
26 to 35 properties 1.75 hours £52.50
36 to 45 properties 2 hours £60
46 to 55 properties 2.25 hours £67.50
56 to 65 properties 2.5 hours £75
66 to 75 properties 2.75 hours £82.50
76 to 85 properties 3 hours £90

The primary relevant person will be invoiced for the fees once works have been completed and there will also be an option to pay by direct debit.

What financial support is available to help us meet the new charges?

Residents may qualify for a discretionary grant for under £1,000 for minor upgrades/works to their private water supplies if they meet certain financial criteria and are in council tax band A-D (this does not include risk assessments or any form of monitoring). Safe and Secure grants are available from the Dorset Accessible Homes Service.

If major improvements are required for private water supplies and works are over £1,000 then residents living in West Dorset are eligible to apply for a council loan through our partner Wessex Resolution CIC.
