Despite a dry first three weeks of August, the utility says it can manage with current supplies.
In its latest post on social media, Guernsey Water describes the first three weeks of August as 'bone dry.'
It quotes Met Office stats that show 0.8mm of rain fell, compared to the average of 32mm this far into the month.
The utility says the gap between what has been used and what has gone into storage is a deficit of 142 million litres.
182 million litres was taken from storage and only 33 million litres went into the reservoirs.
Despite this, there are no plans to introduce restrictions as Guernsey Water says storage is not that far from the 10 year average.
However, it is reiterating the 'don't waste' message.
It says people should not water their lawns or gardens with a sprinkler, and asks that we take short showers and only run the dishwasher when it is full, and on eco mode.
Today, 19 August, has seen the first appreciable rainfall this month, with a line of thunderstorms coming in from the continent.
