Six Reasons a Plastic Biodigester is the Best Septic and Sanitation Solution for your 50×100 Plot.
When building on a 50*100-meter plot, size Matters.
Space and smart design are everything. Whether you’re building rental units, a family home, or a small commercial setup, you want every square meter to count—and that includes how you manage waste.
If you’re in an area without a main sewer line, a plastic biodigester is hands-down the best sanitation solution. At Biotank Africa, we offer a range of affordable, efficient, and eco-friendly biodigesters designed for real Kenyan needs.
Below are Six Reasons why you should use a Plastic Biotank.
1. Compact Design – Built even for Small Plots
A 50×100 plot has limited room for utilities — you don’t want to waste it on a bulky septic system. Our plastic biodigesters are compact, ideal for tight urban plots, rental developments, or private homes.
You get proper sewage treatment without compromising on space for more units, parking, or green areas.
2. Affordable for Every Budget
Biotank Africa’s biodigesters are not only efficient — they’re affordable:
| Size | Capacity | Ideal For | Price (KSh) |
| 1.4 m³ | Up to 10 users | Small families | 39,500 |
| 2.0 m³ | Up to 15 users | Larger families | 55,000 |
| 2.5 m³ | Up to 25 users | Rentals/small institutions | 75,000 |
| 3.0 m³ | Up to 35 users | Hostels, business setups | 105,000 |
Compared to building a concrete biodigester or septic tank (which can cost KES
80,000–150,000+ plus ongoing maintenance), our plastic tanks are much cheaper — and they last over 50 years.
3. Quick and Easy Installation
Takes 1–2 days to install
No need for masonry or curing
Comes ready to connect to your existing plumbing
This is perfect for rental investors, rural homes, or fast-moving projects.
4. Odorless, Clean & Low Maintenance
Our tanks use natural bacteria to break down waste with no smell and no frequent emptying needed.
To keep your system running at peak performance, we also provide:
Bioclean Septic (KSh 1,200) – a bacteria-based powder that safely cleans your biodigester or septic tank
Bioclean Septic Plus 10X (KSh 2,500) – 10 times stronger, breaks down even kitchen grease and drain clogs
Diopit Digester (KSh 950) – a chemical and microbial product that clears blockages, treats 1000L, and keeps tanks flowing
5. Long-Lasting and Weather-Resistant
Our plastic biotanks are made from UV-treated, corrosion-resistant material, ensuring a lifespan of over 50 years with little to no maintenance.
They handle both rainy and dry seasons without cracking or leaking, unlike some masonry systems.
6. Safe for the Environment
The treated water from a Biotank biodigester is safe enough to:
Discharge into a soak pit Irrigate trees or lawns
Safely return to the environment
That means you’re helping reduce groundwater pollution and promoting sustainable sanitation
— one home at a time.
