Enterprise's odd/even water conservation plan has cut consumption from 10.5 million gallons a day, to just under eight million.
However, Mayor Kenneth Boswell says it won't be enough if the record-breaking drought continues.
Mayor Boswell has alerted the city council that he may have to implement a stage three rationing plan, if there is not an appreciable amount of rain in the next 10-days.
Stage three will further reduce the days homeowners can water their lawns.
If the city goes to a stage three plan, it will only affect homeowners. Horticulture businesses will still be allowed to water their plants.
