Stage 2 water restrictions will be apply in the coastal townships of Apollo Bay, Marengo and Skenes Creek between Sunday, October 30, 2011, and Saturday, April 28, 2012.
The move will ensure the limited capacity of the Marengo supply basin copes with the demand of thousands of holidaymakers over summer.
Restrictions will not be required when a new 250-million litre storage is completed in 2014. It will complement the existing 125-million litre basin, with planning well advanced.
Under Stage 2 restrictions, watering of lawns is banned and garden watering is only permitted during limited hours on alternate days. Window cleaning, vehicle washing and watering sporting grounds are also restricted.
Barwon Water Managing Director Michael Malouf said although the Marengo basin was nearly full, restrictions were necessary because of the almost three-fold increase in consumption during the tourist season.
"We need to conserve water over the peak holiday period so the existing system can meet the needs of residents and visitors alike," Mr Malouf said.
"Apollo Bay's population swells over summer and, combined with increased demand due to hotter weather, we need to carefully manage supply."
