When can I test according to WW V2.0?

The ZDHC WWG 2,0 will be applicable from the testing cycle of April 2023. This means that the WW test report uploaded in the Supplier’s Gateway account before 30th April 2023 should be as per the ZDHC WWG 2,0. Usually the sampling and testing for the April 2023 cycle can start from Jan 2023.

As of when do I have to test according to WW V2.0 only?

The ZDHC WWG 2,0 will be applicable from the testing cycle of April 2023. This means that the WW test report uploaded in the Supplier’s Gateway account before 30th April 2023 should be as per the ZDHC WWG 2,0 only. Usually the sampling and testing for the April 2023 cycle can start from Jan 2023. Thus, from Jan 2023 onwards, only the ZDHC WWG 2,0 will be applicable to supplier facilities.

If facility didn't have a flow rate, how does it define 15m3 per day?

The WW discharged from a facility needs to be monitored through a flowmeter that is installed at the point of discharge from the facility. In many countries, this is a legal requirement since the amount of WW discharged by the facility should meet the sanctioned volume given in the License to Operate to the facility. In case such flowmeters are not installed at the facility, then the facility should take action and install the same. Based on the readings of the flowmeter over a 6 -hour timeframe, the sampler will determine if the facility’s WW discharge is below or above the threshold volume of 15m3 per day.
