Emptying a standard domestic septic tank typically costs £150-£300, with most households needing this done once a year or so. Servicing or repairing a sewage treatment plant generally runs £150-£400 for routine maintenance, while a full tank replacement or new installation usually costs £3,000-£7,000 depending on ground conditions and tank size.
