Septic Tank Installation & Package Treatment Plants

Most older septic tanks need upgrading when they no longer comply with current regulations, especially if they discharge into a watercourse or struggle to cope with household demand. Signs include slow drainage, odours, frequent emptying or surface pooling. We assess your existing system and advise whether repair, upgrade or a full replacement is the best long-term solution.

A septic tank separates solids and liquid waste before sending partially treated effluent to a drainage field. A package treatment plant goes further, actively treating the waste using aeration to produce much cleaner, environmentally safe effluent. This often allows discharge to a suitable watercourse and makes treatment plants the most compliant solution under modern regulations.

Most installations require Building Control notification, and some may need planning permission depending on location, discharge route and environmental sensitivity. We manage the entire approval process, including Environment Agency consents, design submissions and all required documentation. This ensures your installation is fully compliant and avoids any expensive issues when selling your property later.

Timescales vary depending on whether approvals are needed, but once consents are in place, most installations take between two and five days on site. We organise everything in advance, keep disruption to a minimum and reinstate the ground as carefully as possible so that your garden or driveway is left clean, tidy and safe.
