Efficient golf course water management is a top priority for water-intensive golf courses. Through smart water resourcing, golf courses can stand to not only save on water costs, but also reduce their carbon footprints.

Many golf clubs rely on expensive mains water to irrigate their golf courses. But using this drinking-quality water is a waste of resources and energy, since lower quality water would be sufficient for irrigation services.

What are the water source alternatives for golf courses?

The most common savings opportunities come in the form of alternatives to mains water. The most suitable option for your golf course’s water will depend on your unique environment and budget.

Here are three options for alternative water sources:

1.Rainwater harvesting

Rainwater harvesting involves the collection and storage of water that falls on areas of the golf course where runoff can easily be collected, such as the carpark or golf club buildings. Although setup can be expensive, rainwater harvesting leads to greatly reduced long-term water costs. It also has a more favourable environmental footprint than mains water, since energy is not being wasted in the unnecessary treatment of the water.

2.Water abstraction

Underground water - The abstraction of groundwater involves installing a borehole and pumping system to make use of water stored underground. The use of this method is area-specific, as your course will need to have suitable rock types beneath it.

Surface water - Water can also be abstracted directly from water sources above ground, such as lakes and river.

Remember - the installation of water abstraction systems need to follow strict controls and legal requirements to ensure that removal of water from the natural environment will not have a negative impact.

3.Greywater systems

A greywater system reuses water that has already been used for another purpose, but has a low contamination level. This water can be used for irrigation with minimal to no treatment beforehand.

Greywater sources include:

●Showers

●Sinks

●Washing machines

For most golf courses, the amount of greywater harvested from these sources won’t be sufficient for irrigation purposes. However, it can be used effectively within the clubhouse to flush toilets etc. In larger golf developments with accommodation and other facilities, using greywater for irrigation could be a feasible option.

Most golf course water management systems that move courses off mains water require a high short-term investment, but will result in reduced water costs in the long-term. Any new water system installed will need to be planned carefully to meet the relevant compliance and legal standards.
