Chris and his team recently decommissioned a septic tank for us and installed a new treatment plant. We were really impressed at how the team carried out the work, keeping any mess to a minimum and thoroughly tidying up each evening. Very professional job from start to finish and would definitely recommend.
Chris and team did an excellent job. Firstly taking us through the entire process of installing a treatment plant and drainage field. Great job done to schedule and hassle free. Job well done. I would highly recommend their services to anyone interested in installing a treatment plant.

All Treatment Plants must now be serviced annually. Keeping a record of maintenance is essential to ensure they work properly when releasing water into the ground or watercourses
We provide expertly designed and installed drainage fields that effectively manage the discharge from your sewage treatment plant, ensuring a safe and environmentally sound solution.
At the heart of our approach is simplicity and clarity. Here’s how we work to ensure your sewage treatment plant installation is seamless and stress-free:
Many homeowners start with a septic tank — but under current UK regulations, a sewage treatment plant is often now required, especially if you’re:
✅ We install septic tanks where still legally allowed
✅ We’ll check your site for free and advise the right solution
✅ Avoid fines — stay compliant from day one
Septic systems are essential for managing wastewater, especially in areas not connected to centralized sewer systems. They offer several significant benefits for homeowners and communities. Here’s why septic systems might be the right choice for you:
Compared to extending municipal sewer lines, septic systems are often more affordable to install, particularly in rural or remote areas.
With proper maintenance, a septic system can last for decades, reducing ongoing expenses compared to municipal sewage fees.
Properly maintained septic systems can enhance your property’s value by providing a reliable and efficient wastewater solution.
They support residential and commercial development in rural areas, contributing to local economic growth.
With a septic system, you are independent of municipal sewer services, which can be an advantage during citywide maintenance issues or outages.
Any issues with a septic system are limited to your property, minimizing the risk and impact compared to large-scale municipal system failures.
Septic systems help recharge local groundwater supplies by allowing treated water to naturally percolate through the soil.
The natural processes in septic systems can return essential nutrients to the soil, enhancing soil health and fertility.
Septic systems can be customized to suit different property sizes and soil conditions, making them a versatile solution for various landscapes.
Whether for a single home, a small community, or a business, septic systems can be scaled to meet your specific requirements.
Homeowners are encouraged to be mindful of their water usage to prevent overloading the system, which naturally promotes water conservation.
Septic systems use soil to filter and treat wastewater, making them more eco-friendly than municipal chemical treatments.
