Our invoicing system for Trade Effluent – TEIP – is designed to produce the most accurate invoices possible, which will always reconcile against Wholesale charges. Many customers want to know that their charges are auditable and can be tracked back to these Wholesale charges. Unfortunately, if the Wholesaler enters sampling data in the Central Market Operating System after the month in which it is due to be recorded, this gives rise to a change in charges. This is an issue affecting all areas of England, not just Castle Water. We prefer to always be transparent, and therefore will send a revised bill. We are working with the Market Operator to stop the late upload of sampling data, which we think is unnecessary, and hope that sometime soon we will be able to eliminate the need for these reconciliations.
Trade Effluent is any liquid waste discharged into the sewers from a business or industrial process. Trade Effluent is regulated to ensure the sewerage network can adequately handle and treat the waste. This is to protect the health and safety of staff and to protect the environment.
The types of businesses that normally require a consent include: car washes, launderettes and dry cleaners, transport depots, breweries, dairies and commercial swimming pools. Trade effluent customers can be large or small businesses.
Trade effluent does not include waste that is classed as regular sewerage – waste water from kitchens, bathrooms and toilets; therefore, most hotels, restaurants, cafes, pubs, and hairdressers.
To regulate Trade Effluent, businesses are provided with a licence, or discharge consent. Samples of the trade effluent discharge are taken regularly to ensure customers are complying with the terms of their consent.Â
It is a criminal offence to discharge trade effluent waste without a consent.
If you believe that your business may require a Trade Effluent consent, please complete the application form and send it to us.Â

Yes. Complete the relevant Direct Debit mandate for your business here.
When we set up your Direct Debit, we will start collecting your monthly payments as soon as possible to make sure you avoid paying a lump sum. We may start by collecting £30 per month but we will adjust this amount as soon as we issue your first bill. We will always give you 10 working days’ notice before we collect payment.
We review your charges every year, or every six months if the supply is metered, and then divide the total balance on the account by twelve or by six to work out your fixed monthly payments.Â

If you pay by fixed Direct Debit, you will pay the same amount every month, but we will review this regularly to make sure you’re paying the right amount. You will always be given 10 working days’ notice before we change your monthly amount. With a fixed Direct Debit, you can plan ahead and don’t need to worry about paying late. You spread out your charges and avoid paying a lump sum.
If you pay by variable Direct Debit, you will pay a different amount every time we issue a bill because your bill can vary depending on your consumption and meter readings, or other factors. On your bill, we explain that we are going to collect the full outstanding balance in one go. You will always be given 10 working days’ notice before we collect the payment. With a variable Direct Debit, you will pay less often. You don’t need to worry about paying late and you will always pay exactly what is due.
If you want to pay your bills in full by Direct Debit instead of paying in fixed monthly instalments, let us know. The amount you pay after each bill will vary according to the value of the bill. You will always pay exactly what is due.
If you want to spread out your payments in fixed monthly instalments, let us know.

If there is no water meter at your premises, your bill is calculated based on an estimate set by the Wholesale supplier. This may be based on the Rateable Value of your premises or what’s called an ‘assessed volume’ which depends on what the Wholesaler knows about your business and what water is being used for. If you think the estimate is wrong or if you are interested in having a meter installed, let us know.
Please provide a meter reading and a photograph if it is safe for you to access your meter. Submit this via our portal and we will use this reading when we calculate your next bill.
