Private water supplies

A private water supply is any supply not provided by a statutory water company – in other words, it is not a public 'mains' supply. It may serve one property or several. In our Borough, public mains water supplies are provided by either Southern Water Services or Portsmouth Water, depending where you live.


A private water supply can include:


The new Private Water Supply Regulations 2009 came into force on 1st January 2010. Their revised quality standards and new monitoring duties mean we must carry out a risk assessment on specific areas of the supply. This is relevant for supplies for human consumption which on average provide 10 or more cubic metres of water per day, serve 50 or more people or are supplied/used as part of a commercial or public activity.

Keeping your private water supply safe

We maintain a record of private water supplies in the Borough and undertake risk assessments and periodic sampling to check that they meet statutory drinking water standards. We charge for this. Our fee is made up of the 'actual costs' we incur, including our investigating officer's hourly rate plus on costs and analysis costs charged by external contractors. Our costs will not be more than the statutory maximum charges included in the Water Supplies Regulations 1991.
