Licence required

If you choose to apply for an annual licence, you’ll be asked to use points on our approved washout list. These are pre-checked points. The washout list will detail any restrictions.

We do not sell or hire standpipes. The Hydrant Licence will be subject to you using your own standpipe. It must be in good condition and fitted with an approved Double Check Valve to protect against backflow.

Please note: For customers wishing to use a 63mm hydrant, the minimum charge band is 1-10 cubic metres/day.

We’re currently unable to provide standpipes for hire or sale. However, we operate with unmetered standpipes and have always allowed customers to use their own standpipe(s). The standpipe(s) must be in good condition and fitted with a working double-check valve.

Using your own standpipe(s)

Please Note: All standpipes must be in good working order and have a working Double Check Valve fitted.
