Highland Septic Tanks

If you’re installing a new system, upgrading an existing one, or need repairs, we’re here to help. We understand the challenges of working in the Highlands—whether it’s rocky terrain, high water tables, or remote locations—and we tailor every project to suit the specific needs of your property.

Septic Tanks vs. Treatment Tanks: What’s the difference?

Septic and treatment tanks both handle wastewater, but they work in different ways:

• Septic Tanks: These are traditional wastewater systems that separate solids from liquids. The liquid wastewater is filtered into a drainage field or soakaway, while solids break down naturally in the tank.
• Treatment Tanks: Also known as wastewater treatment systems, these use aeration and filtration technology to break down waste more effectively. The outflow water is much cleaner than that from a septic tank, making treatment tanks an eco-friendly option, especially in environmentally sensitive areas.

Not sure which system is right for you? We’ll assess your property and recommend the best solution based on soil conditions, drainage, property size, and local regulations.

Our Septic & Treatment Tank Services

We offer a full range of septic and treatment tank services, from initial planning to ongoing maintenance.

1. Site Surveys & System Design

Every good system starts with a thorough site survey. We assess your land to determine the best placement for your tank, ensuring optimal drainage, compliance with local regulations, and minimal impact on the surrounding environment.

2. Septic & Treatment Tank Installation

We handle everything from excavation to final testing. Our team ensures:

• The right system for your property
• Proper installation to prevent leaks or future issues
• Compliance with SEPA (Scottish Environment Protection Agency) regulations

3. Repairs & Upgrades

If your existing system isn’t working properly—blockages, slow drainage, bad smells, or flooding—we can diagnose the issue and carry out the necessary repairs. If your septic tank is outdated or no longer meets environmental standards, we can upgrade it to a more efficient treatment system.

4. Regular Maintenance & Servicing

Routine servicing prevents costly repairs and extends the lifespan of your system. Our maintenance services include:

• Emptying and cleaning to prevent buildup
• Inspection of drainage fields and pipes for blockages or leaks
• Checking for compliance with current environmental standards

If you’re not sure when your tank was last serviced, it’s a good idea to schedule an inspection before small issues turn into major problems.
