Why Choose Us?

Considering a Septic Tank? We Make Off-Mains Drainage Simple

For properties not connected to the public sewer network, a private drainage system like a septic tank or a small sewage treatment plant is essential. You might be considering one as part of a new build project, or perhaps your existing septic tank is old, failing, or no longer compliant with the latest environmental regulations. It might even be that your property, perhaps an older home across Merseyside or Cheshire, has a problematic cesspit that needs upgrading to a more sustainable and legally compliant solution. Whatever your situation, our team is here to guide you. We understand the nuances of ground conditions, local authority requirements, and the crucial 'General Binding Rules' for septic tanks. Our professional approach means we assess your specific needs, recommend the most suitable system, and manage the entire installation process, providing you with peace of mind.

Who We Are

Our Seamless Septic Tank Installation Process

When you choose Avery Drainage Solutions for your septic tank installation, you’re partnering with a team dedicated to efficiency and quality. Our process begins with a thorough site survey to understand your property’s layout, soil conditions (often requiring a percolation test), and specific drainage requirements. We then advise on the best system – whether it’s a traditional septic tank or a modern sewage treatment plant – that meets current regulations and your budget. Our skilled groundworks team, all CSCS certified, carries out the excavation, installation of the tank, and connection to your property's internal drainage system, including the necessary pipework for foul water and the soakaway system. We work diligently, aiming to minimise disruption to your property while maintaining the highest standards of safety and workmanship. We pride ourselves on clear communication every step of the way, so you always know what's happening.

Septic Tanks vs. Treatment Plants: Navigating Your Options with Confidence

One of the most common questions we get asked, especially in areas like St Helens or parts of Lancashire, is whether to install a septic tank or a sewage treatment plant. It's an important decision, especially since the 2020 'General Binding Rules' came into effect, impacting many older septic tank systems that discharge directly to watercourses. A septic tank offers a basic level of treatment, separating solids from liquids before the effluent disperses into a drainage field. A sewage treatment plant, however, provides a higher level of purification, producing cleaner effluent that can often be discharged directly into a ditch or watercourse where permissible, or to a smaller soakaway. Our experienced specialists will clearly explain the pros and cons of each, considering your property’s location, ground conditions, and local environmental regulations. We help you make an informed choice that’s compliant, cost-effective, and right for your long-term needs.
