Be clear about the service you need
Septic tank emptying, cesspit emptying, sewage treatment plant servicing, pump station work and drain repairs are related but not identical jobs. Explain what system you have if known and what problem you are experiencing. Ask the supplier if it offers that particular service.
Share site and access details
Provide your postcode, tank or chamber location, estimated tank size if known, hose distance, gate access and any narrow lanes or soft ground. Tanker size and access can affect whether a supplier can do the work and how it is priced.
Understand the quotation
Ask whether the quote covers the visit, emptying or servicing, disposal, call-out timing, extra hose or access charges, and any records or follow-up advice. For repairs or installation, confirm whether a survey is needed first.
Check relevant registration and disposal
Ask the supplier what waste-carrier or environmental registrations apply to the service and how waste will be handled. Check current official requirements with Natural Resources Wales where relevant. Do not rely solely on a directory listing as proof of authorisation.
Keep a record
For recurring emptying or maintenance, keep receipts, dates, service details and any recommendations. Ask the company whether it offers reminders, but confirm the right interval for your specific system with the appropriate guidance or installer.
