Septic tank conversion means turning your old tank into a modern bio digester that breaks waste down with natural bacteria. It fixes smell, overflow and constant emptying at the source. CleanEarth Bio Digester Services converts tanks in Lagos, Ibadan, Enugu and Abuja, usually without digging up your whole compound.
If your septic tank is a regular source of stress, you do not always need to start again. In many cases the tank you already have can become the base of a better system. This guide explains how that works, when it makes sense, and what to expect.
What is a septic tank conversion?
A septic tank conversion changes your existing tank so it works as a bio digester. Instead of just holding waste, the system now uses natural bacteria to break it down.
We start by assessing the tank you already have. Then we convert it to bio digester technology. The goal is a system that treats waste properly, so you need fewer desludging trucks, deal with less smell, and spend less over time.
How do you know your septic tank needs converting?
You need conversion when the tank smells, overflows, drains slowly, or needs emptying again and again. These signs mean the tank is no longer coping with your property.
| Sign | What it usually means | What conversion changes |
|---|---|---|
| Bad smell around the tank | Waste is sitting and rotting | Waste is treated and broken down |
| Overflow after rain or heavy use | The tank is full or struggling | Better treatment and less buildup |
| Slow drains and toilets | The system is backing up | A system that copes with your daily use |
| Frequent desludging trips | Solids pile up quickly | Reduced need for desludging |
| Rising running costs | Repeat truck bills | Lower costs over time |
If you see two or more of these signs, book an inspection. It is better to act before the problem becomes an emergency.
How does CleanEarth convert a septic tank?
We follow a clear process, and we explain each stage in plain language.
- Inspection. We assess your existing tank and system, and check for blockages, leaks and design faults.
- Plan. We tell you what we found, whether conversion is the right answer, and what it will involve. You get a clear quote with no pressure.
- Conversion. We convert the tank to bio digester technology with careful, tidy work on your property.
- Testing. We test the system and walk you through how it works.
- Support. We stay available for maintenance, repairs and questions.
Will conversion mean digging up my whole compound?
No, not in most cases. Most conversions are completed without digging up your entire compound or rebuilding from scratch. We work carefully and keep disruption to your property as low as possible.
Every site is different, so we confirm what is needed during the inspection. We will tell you honestly if your situation needs more work.
What are the benefits of converting instead of building new?
Conversion lets you keep what already works in your property and fix what does not. For many owners it is faster and less disruptive than a full rebuild.
- Less disruption: your compound stays mostly as it is.
- Fewer desludging callouts: waste is broken down, not just stored.
- Less smell: treated waste does not sit and rot.
- Lower costs over time: fewer trucks and fewer repairs.
- Better for the environment: natural treatment and less reliance on trucks.
When is conversion not enough?
Conversion is not enough when the original system was badly designed or is far too small for your property. In that case, patching it will keep failing.
For these cases we offer two other services:
- System upgrades, when your setup is outdated or too small and needs more capacity.
- Redesign and rehabilitation, when the system was poorly designed from the start and we need to rebuild it properly.
We tell you honestly which one you need. We do not recommend work that is not necessary.
Which properties benefit most from conversion?
Any property with an old septic tank that smells, overflows or needs constant emptying can benefit. We convert tanks for homes, estates, schools, hospitals, hotels and offices.
Large properties often see the biggest change, because they have more people using the system and so feel every failure more. A hotel or school that cannot afford sanitation problems gains the most from a reliable system with a maintenance plan.
Does conversion work in every Nigerian city?
Conversion works wherever the tank can be assessed and the ground allows it. We serve Lagos, Ibadan, Enugu and Abuja, and each city has its own conditions.
- Lagos: tight plots and wet ground in some areas
- Ibadan: large compounds and ground that can be rocky in parts
- Enugu: slopes and heavy seasonal rain
- Abuja: fast growing estates, hotels and offices
That is why we assess your property first. Ground and space decide the design.
How much does conversion cost?
The cost depends on the size and condition of your tank, the number of people using the property, and the work needed. We cannot give a fair price without an inspection.
After the visit we give you a clear quote. Conversion often costs less than building a new system, and it can save money over time through fewer trucks and fewer repairs.

Frequently Asked Questions
Can any septic tank be converted to a bio digester? Many can. We assess your tank first, then tell you honestly whether conversion is the right choice or whether an upgrade or redesign would work better.
How long does a conversion take? It depends on the size and condition of your tank. We will give you a clear plan after the inspection.
Will I still need to empty the tank? You will need to far less often. Conversion reduces the need for desludging because waste is broken down.
Does conversion remove the bad smell? It is designed to cut smell, because waste is treated and not left to sit. Results depend on the condition of the system, which is why we inspect first.
Do I need a maintenance plan after conversion? It is a good idea. Regular checks catch small problems early, before they become expensive.
