WATER AUDIT

Today, with the scarcity of water resources in the region and in the world, strict water control policies are widely applied in industries, so reusing water is the trend of enterprises. For that reason, WATER AUDIT is one of the most important methods that helps enterprises optimize using of water resources. Using water efficiently will save much cost for enterprises not only on water costs but also on related electricity consumption cost.

1. WHAT IS WATER AUDIT?

Similar to energy audit, WATER AUDIT is a method to quantify the sources of water being used in the enterprise, thereby understanding the current state of water consumption, minimizing losses, and identifying opportunities to improve water use efficiency.

To start executing water audit, a water balance diagram will be established based on available or estimated data. This diagram will help identify areas that need to be prioritized for detailed assessment (for example, focusing on areas with the highest water consumption

2. WHY SHOULD THE WATER AUDIT BE CARRIED OUT?

• Identify loses of water consumption
• Improve efficiency of water use in enterprises as well as supporting in meeting requirement on water KPI from clients of enterprises or Law (if any)
• Minimize the waste water increasing
• Minimize impacts due to water scarcity
• Reduce water consumption cost
• Reduce cost of waste water treatment
• Contribute to water source and environment protection

3. WHEN SHOULD WATER AUDIT BE DONE?

There is no any regulation regarding on the deadline for water audit execution, but it should be done when (for enterprises):

• Identify any particular increasing/unusual of water consumption
• Or requirement from clients and related law
• Or it should be initiative from enterprises in fostering the program on energy use efficiency

4. WHO CAN BE IN CHARGE OF EXECUTING WATER AUDIT?

• Water meter
• Water ruler
• Water can
• Water pressure meter
• Water flow meter
• Calculating tools
• TDS
• etc.
