Southern Water want to hear from customers how often it is acceptable to introduce hosepipe bans in a drought.
The company is hosting a public consultation on its 25-year Water Resources Management Plan, which sets out how there is enough water for the future.
The consultation will close on August 12, 2013 and touches issues such as hosepipe bans and plans to secure a more resilient water supply between 2015 and 2040.
The proposals allow for the introduction of Temporary Use Bans, which include hosepipe bans once every ten years on average.
Meryrick Gough, Water Strategy and Resources Manager, said: "Our aim is to only introduce hosepipe bans after we have experienced at least two dry winters in a row.
At the moment we are seeing Temporary Use Bans in Sussex and Kent once every six years.
The resources in Hampshire and Isle of Wight are more resilient, with the last restrictions on the Island in place in 2006 and none in Hampshire since 1976."
