YANCHEP has ranked No. 7 in the top 10 suburbs for sprinkler roster infringements in 2017.
There were 140 infringements handed out to Yanchep residents using scheme water last year.
Baldivis with 467 infringements and Brabham with 299 infringements ranked No.1 and No. 2 respectively.
Yanchep did not make the top 10 suburbs for sprinkler roster infringements related to bore water use last year.
Water Minister Dave Kelly said many people did not realise more than 40 per cent of household water use was outside in the garden, so this was where most could make big savings.
Mr Kelly said while the metropolitan area had a mild summer, it received no rainfall in February and it appeared as though it would be an unseasonably hot autumn.
“This means it is essential people keep to their sprinkler roster days,’’ he said.
Sprinkler rosters are in place across Perth, with scheme water users able to use sprinkler systems two days per week, either before 9am or after 6pm.
Bore water users also follow the sprinkler roster but have one extra watering day.
People who witness a breach of the sprinkler roster can make a report at https://www.watercorporation.com.au/breach or call 13 10 39.
Households receive a $100 fine if they are sighted breaching the sprinkler roster by an inspector and a warning if they are reported by a member of the public, or if an inspector observes sprinklers have been used.
