Recovery of incurred costs

Formal sampling charge

The recovery of costs incurred by Southern Water in respect of formal sampling undertaken in accordance with our policies and procedures, due to failing to comply with your customer's consent.

As per the G4 process, when all sample analysis is completed and verified the results are sent to the trade effluent customer by email. The results are also made available to their retailer through our retailer portal.

Retailers will be sent an email notifying them when results are added.

You can find the results under Section 5: Trade Effluent - G Forms – TE monitoring and search by SPID.

Consent conditions may require flow measuring equipment such as a private meter to be provided, maintained and records kept. The cost of installing and maintaining such equipment will be the responsibility of the discharger.

Assessment of flow by other means such as private water meters or process meters may also be used by trade effluent dischargers. This can aid with calculation, accuracy of billing, and improved monitoring.

Any flow measuring equipment and installation used for trade effluent billing should be to MCERTS standard.

Yes. You'll need to register private meters used to calculate trade effluent bills in the market.

Please notify us that your customer has installed, exchanged, or has an issue with a private meter with a G01 which will be submitted on the Bilateral Hub. Please complete this form and attach to the G01 enquiry.  Please refer to the Market Operational Codes (Schedule 1 Part 3) under B12, B13 and B14 to view the processes that you may need to follow.
