If you’re looking to buy a septic tank in Kenya, most of what comes up online is either a vague price range or a listing that never actually says what capacity you’re getting for the money. Poa Tanks keeps it simple here: one tank, the 2,000 litre horizontal septic tank, priced at KSh 50,378.25. That’s down from a listed KSh 77,505, and delivery to major towns is already folded into that figure.
Septic tank prices in Kenya (Poa Tanks)
| Tank | Price (KSh) | Capacity | Type |
|---|---|---|---|
| Horizontal Septic Tank | 50,378.25 | 2,000L | Horizontal, single-piece |
Worth flagging upfront: Poa Tanks only stocks this one septic tank size right now. But at a 35% discount off the listed price, with delivery to major towns already built in, there isn’t much left to add on top once you’ve decided 2,000L works for your property.
Is a 2,000 litre septic tank enough?
Here’s the honest answer: it depends, but as a rough industry benchmark, 2,000L usually covers a small to medium household running normal domestic wastewater flow with periodic desludging. What actually determines the right size is occupancy, how much water the household uses, and how often you’re willing to have the tank emptied. A bigger property or a shared compound with several households is a different calculation entirely, and usually needs either a larger tank or more than one connected in series.
Not sure where your property falls? Talk to Poa Tanks about your household size and site before you order. It’s a far cheaper conversation to have upfront than fixing an undersized tank after installation.
What’s actually included at this price
- Delivery to major towns within Kenya, built into the KSh 50,378.25 price (locations outside the standard delivery grid may carry a transport charge)

- Horizontal, single-piece construction at 2,000L
One thing worth knowing before you commit: Poa Tanks’ well-known 10-year warranty is written specifically for their black above-ground cylindrical tanks and loft tanks. It doesn’t automatically carry over to the septic tank range. So if warranty coverage matters to your decision, and it probably should, ask the sales team directly what’s covered on the septic tank rather than assuming it mirrors their standard tank policy.
Installing a septic tank correctly
Unlike a water tank sitting above ground where you can eyeball it any time, a septic tank goes into the ground and stays there. That’s exactly why getting the install right the first time matters so much more. Good practice means excavating to the correct depth, setting the tank on a firm and level base, and making sure the inlet and outlet pipework is connected properly before anything gets backfilled. Bad pipework connections are, by a wide margin, the most common reason septic systems fail early. This is one job worth paying a professional to confirm rather than guessing your way through it.
Septic tank vs. regular water storage tank
People sometimes lump these together, but they solve completely different problems. A water storage tank holds clean water ready for use in the home. A septic tank sits below ground and treats wastewater, kept well away from the house itself. Building on a property without mains sewer access? You’ll likely need both, a water tank for supply and a septic tank for waste. Poa Tanks carries both lines, so it’s worth pricing them together if you’re setting up a full system rather than buying one tank in isolation.
Frequently asked questions
How much does it cost to buy a septic tank in Kenya?
At Poa Tanks, the 2,000 litre horizontal septic tank runs KSh 50,378.25, down from a listed KSh 77,505, with delivery to major towns included in that price.
What size septic tank do I need for a home in Kenya?
As a general guide, 2,000L suits a small to medium household. Actual sizing comes down to occupancy, water use, and how often you’ll desludge. Bigger properties or shared compounds usually need more capacity, or more than one tank.
Does Poa Tanks offer more than one septic tank size?
Right now, just the one: the 2,000L horizontal septic tank.
Does the septic tank come with the same 10-year warranty as Poa Tanks’ water tanks?
Not automatically. That 10-year warranty is written for Poa Tanks’ black above-ground cylindrical tanks and loft tanks specifically. Confirm what’s actually covered on the septic tank with the sales team before you buy.
Do I need a water tank and a septic tank, or just one?
Different jobs entirely. A water tank stores clean water for use, a septic tank treats wastewater. Most off-grid or partially off-grid properties in Kenya end up needing both.
