Customers in the Sussex supply area face tighter hosepipe rules after a prolonged dry spell pushed a key reservoir to less than a quarter of capacity. The change was announced on 2 October, with the revised temporary-use restrictions due to begin at 00:01 on 9 October.
What is changing in Sussex
South East Water is withdrawing the previous exemptions to its Sussex hosepipe restrictions. The remaining exceptions are narrowly focused on health, safety and welfare, including animal welfare. The change applies in the company’s Sussex supply area, rather than across every place it serves.
In practical terms, customers who had relied on an earlier exemption will generally no longer be able to use a mains-connected hose for activities such as garden watering, washing private vehicles, filling domestic pools or cleaning patios. Watering cans, buckets and certain efficient drip or trickle systems remain among the alternatives described for some uses. The restrictions do not prevent essential use where it is needed to protect people or animals.
A separate application for wider limits
The supplier has also applied for a Non-Essential Use Ban, a separate measure aimed at commercial and other non-household water use. That application has not been approved. It requires a decision by the Environment Secretary, so it should not be treated as an immediate new prohibition on businesses.
The distinction matters. The revised hosepipe rules are a change to the existing temporary-use ban for Sussex customers, whereas the proposed wider measure remains subject to the formal approval process. Customers in the supplier’s other areas continue under the earlier temporary-use arrangements rather than the Sussex change.
Ardingly at a critical point
The immediate pressure point is Ardingly Reservoir, which supplies Haywards Heath and surrounding communities. It stood at 22.8% full on 27 September. The level has moved the reservoir into the next stage of the company’s drought plan, prompting the additional steps intended to protect essential supplies and the environment.
The company says the reservoir serves about 228,000 customers. It has previously obtained a drought permit which allows reduced releases from Ardingly into Shell Brook, a tributary of the River Ouse, and lowers the minimum flow left at Barcombe Mills after abstraction for customers. Those changes illustrate the trade-offs being managed between public supply and local rivers; they do not mean that environmental protections have disappeared.
Dry September adds to a difficult year
The tightening comes after September became the sixth month this year with below-average rainfall across England. National rainfall was 65% of the usual level for the month, while the South East received 57%. For the country as a whole, reservoir storage would normally be close to 74.3% at this point in the year, yet many reservoirs remain below half full.
Cooler weather has reduced demand, but the position still depends heavily on rainfall and how much water is used. Recent national assessments say soils remain very dry and indicate that substantially above-average rain over the coming months would be needed for a full recovery from drought conditions by next spring.
What customers should do now
For Sussex households and affected local businesses, the immediate date to note is 9 October. They should check whether an activity is restricted, avoid assuming that a previous exemption still applies, and use non-mains or lower-volume alternatives where permitted. Anyone relying on a health, safety or welfare exemption should consult the detailed conditions before using a hose.
The broader message is that the new application is a contingency step, not a confirmed business ban. Its outcome, the autumn weather and reservoir recovery will determine whether further measures are required.
