He was extremely patient, professional, and determined to find a solution and resolve the blockage, keeping me informed throughout the process.

I really appreciated his dedication and willingness to help, and the issue was resolved efficiently thanks to his efforts. I would definitely recommend Carlo and his company to anyone looking for a reliable, professional, and customer-focused service.

The person was very friendly, my drain got unclog, and I even had a guarantee (for a month or two, can't remember) that if the problem came back, they would come for free.
That's the kind of worker that you're happy to pay - highly recommended

How We Carry Out Your Sewage Treatment Installation

Our engineers follow a thorough and proven process to ensure your sewage treatment system installation is compliant, long-lasting, and tailored to your property’s needs — whether residential or commercial. From site surveys to final sign-off, we handle every detail with precision and care.

Here’s how we deliver every installation:

How Far Does a Sewage Treatment Plant Need to Be From My Property?

UK Building Regulations require that any sewage treatment plant or septic tank must be installed at least 7 metres from a habitable building. This rule is in place to ensure safety, prevent odour issues, and avoid contamination risks.

In cases where a 7-metre distance isn’t physically possible — such as small plots or awkward site layouts — your local Building Control inspector may allow an exception. These are usually granted only when there’s no other viable alternative, not for convenience or aesthetics.

At 24hrs Drainage, we manage this entire process for you. All of our installations include full Building Control sign-off as standard, handled through our trusted partners. Whether you’re positioning a tank near your home or planning a sewage plant discharge to watercourse, we’ll ensure every part of the job is legal, compliant, and stress-free.

How a Sewage Treatment Plant Works

Understanding the internal process of a sewage treatment plant helps you see why it’s such an effective solution for off-mains properties. While system design varies slightly between brands, most follow a similar three-stage cycle that turns wastewater into safe, environmentally approved discharge.

If you’re wondering how to install a domestic sewage treatment plant, it starts with choosing the right system based on property size, usage, and ground conditions. But here’s what actually happens inside the unit once it’s up and running:

1. Primary Settlement (Solid Separation)

The first stage mimics a septic tank — incoming wastewater enters a chamber where gravity causes solids and sludge to settle at the bottom. This removes the bulk of pollutants, allowing clearer liquid to flow forward for further treatment.

2. Aeration & Biological Treatment

In the next chamber, air is introduced using a small built-in compressor. This oxygen supports aerobic bacteria, which actively break down organic matter in the liquid. This biological process is the core of treatment, turning waste into clean effluent.

3. Final Clarification (Residual Filtration)

After purification, any remaining particles settle out in a final stage. In most systems, this allows clear, treated water to be safely discharged to a drainage field, soakaway, or nearby watercourse — depending on your setup and permits.

The exact method depends on the system you choose — from simple gravity-fed units to advanced sequence batch reactors or high-efficiency models with smart controls. Want help choosing the right one? Our team will walk you through the options during your free site survey.

Sewage Systems for Property Extensions & Renovations

When extending or renovating your home, your existing drainage system may no longer meet new capacity or compliance standards. Our engineers can assess, upgrade, or replace your setup with a modern, efficient sewage system for home renovation projects of any scale.

Common upgrade services include:

System Expansion & Integration: We modify or extend your current system to handle additional bathrooms, kitchens, or utility rooms without compromising flow or performance.
Treatment Plant Replacement: For properties still using old septic tanks, we install compact sewage treatment plants that meet current environmental discharge rules and increased usage demands.
Drainage Field Upgrades: We redesign and rebuild outdated soakaways or drainage fields to ensure efficient discharge and compliance with Environment Agency regulations.

Every installation is carried out with minimal disruption, ensuring your renovation or extension meets building regulations, performs reliably, and adds long-term value to your property.

Answers to Common Sewage Plant Installation Questions in Reading, Berkshire

If you have a question of your own, then please ask.

1. Do I need to connect my sewage treatment plant to mains electricity?

Yes — most sewage treatment plants require a small amount of electricity to power an air compressor or motorised system that oxygenates the waste during treatment. The energy usage is typically very low, often similar to running a small household appliance.

2. Can a sewage treatment plant be installed in a flood-prone area?

It’s possible, but it requires additional planning. Flood-prone or waterlogged sites may need raised installations, reinforced tanks, or enhanced drainage solutions. Our team will assess your site conditions during the survey and recommend a safe and compliant setup.

3. Will a sewage treatment plant produce any smell?

A properly installed and maintained system should produce little to no odour. Most units are sealed and ventilated to prevent smells escaping. Odours typically only occur if the system is overloaded, not serviced regularly, or installed incorrectly.

4. Is a sewage treatment plant noisy to run?

No — these systems are designed to run quietly. The air pump or motor generates minimal sound, often quieter than a refrigerator. With proper placement, you’re unlikely to hear it from inside your home.
