There are two different business water audits: a water-saving devices audit and a comprehensive audit.
Water-saving devices audit
This is the most basic audit and identifies the basic changes that you’d need to make to your business’s water-using appliances to improve efficiency.
It includes inspecting, for example, your water meter, running toilets, outdoor sprinklers, water treatment units and faucets.
If any leaks and inefficiencies are found, the auditor would recommend the installation of water-efficient fittings to reduce water wastage. This may include the installation of flow restrictors and tap aerators.
Comprehensive water audit
This audit is mostly performed in the industrial sector where a lot of water is used daily.
It looks at all instances of water consumption within the business and its operations. This water audit is performed by a specialist water auditor and aims to identify how programmed processes and equipment can be adjusted and optimised to improve water efficiency.
The auditor may also suggest ways in which a business can reduce its overall water consumption, including, for example, using rainwater to supply water to outdoor sprinklers or flush toilets to reduce the usage of fresh water.
A comprehensive audit’s information can be used to give businesses a better understanding of how much water they use and the amount of water that can be saved if water-wise saving techniques and technology are implemented.
