The Department of Agriculture, Environment and Rural Affairs (DAERA) has asked farmers, businesses and councils to be mindful of the amount of water they use during the spell of warm, dry weather.
The government body has also reminded those who draw water from the source to be aware of the regulations.
As well as this, the Northern Ireland Environment Agency (NIEA) said it has streamlined its procedures to more rapidly respond to farmers, small businesses and local councils who have an urgent need of water at this time.
It has pledged that where the protection of a crop needs irrigation, animals require drinking water, or a new recreational area needs sprinklers to be established, it will do its best to assist.
Under the current legislation, business or farms are permitted to use up to 10,000 litres per day (2,200 gallons) automatically. If this low volume abstraction is to be taken from a waterway or lake, then the abstractor must install a still well as this will prevent animal life or fish from being impacted.
For a daily volume between 10,000 and 20,000 litres or 2,200 to 4,400 gallons per day, then the business, farm or council will need to notify NIEA and indicate where the proposed abstraction point is to be. There is no fee for this notification.
For any amount greater than 20,000 litres (4,400 gallons) per day then a full licence is required. An authorisation like this can be granted for a seasonal period. The application fee for this type of full authorisation is £157.
