Describe the wastewater before agreeing how it will be discharged

We identify processes producing wastewater, their relationship with facility operations and how separate streams are managed. Available test results, balances, pretreatment information and discharge locations are reviewed. We distinguish evidence describing typical operation from information about changing loads, start-up or other agreed situations relevant to the characteristics of the discharge entering the sewer system.

Wastewater volumes and parameters are set against the requirements identified for the particular agreement. We check units, reference periods and installation descriptions so incompatible information is not combined in the documentation. Where representative results or process details are missing, we identify the required additions. Preparation takes account of the roles of the designer, facility operator and any testing provider.

The documentation concerns a specific discharge arrangement and recipient. It does not replace the recipient's conditions or a decision by the relevant authority. Preparing the submission material is distinguished from additional testing, pretreatment design or connection works. A change in production or wastewater composition may require the original characterisation to be revisited.

Technical data

What you receive

You receive documentation for the sewer operator or authority, including an organised wastewater characterisation, technical information and agreed attachments. It records operating conditions, information sources and any gaps. The material supports explanation of the proposed discharge and responses to questions about its quantity, quality and relationship with the production process.
