Septic tank cleaning — emptying, pumping and biological treatment

Sealed vacuum trucks, fast response, eco-friendly disposal. Biological treatments that extend the interval between emptyings.

Septic tank cleaning
in Serbia

Septic tank cleaning is a job that every household or property off the mains sewer faces sooner or later. Regular septic tank maintenance prevents unpleasant odours, overflows and damage to the drainage field. BioClean by EZO Green offers a complete set of septic system services — from fast emptying to biological treatments that solve problems for the long term.

Our team uses special sealed vacuum trucks that fully prevent leaks during pumping and transport — especially important in urban areas and for properties near water sources. We handle tanks of every size — from small 2 m³ domestic tanks to large commercial and industrial systems of 50+ m³.

Besides emptying, we also offer biological treatment of the system with our EzoSeptik product — a concentrate of bacteria and enzymes that speeds up the breakdown of organic matter in the tank. Regular use can cut emptying frequency by up to 50%, eliminate unpleasant odours and extend the life of the wastewater drainage field. We transport all contents to authorized disposal sites.

Our full range of
septic tank cleaning services

The complete package — biological products, certified team, documentation.

Septic tank emptying (domestic)

Standard septic tank emptying for family homes, holiday cottages and residential buildings off the mains sewer. Sealed pumping with specialist equipment — no leaks, no odours during the work.

Commercial and industrial emptying

Emptying of larger septic systems at hotels, restaurants, industrial sites, campsites and utility companies. High-volume emptying in multiple loads, coordinated with the client's operations team.

Wastewater pumping

Wastewater pumping for properties without mains sewerage — grey water, sewage, water from basements and flooded spaces. Fast service with special high-capacity pumps.

Biological septic treatment (EzoSeptik)

Application of EzoSeptik biological products — a concentrate of bacteria and enzymes that breaks down organic matter in the septic tank at a molecular level. It reduces the amount of sludge, extends the interval between emptyings and eliminates unpleasant odours.

Soakaway and drainage pit cleaning

Cleaning of soakaways, drainage systems and filter fields at properties without a conventional septic tank. Removal of built-up sludge, flushing of drainage pipes, microbiological treatment to restore permeability.

Emergency response

Septic problems don't keep office hours. For overflows, blockages or urgent emptying — we are available 24 hours a day, seven days a week.

What working
with us looks like

From the first call to the final documentation — a transparent, documented and compliant process.

01

Call or online enquiry

Phone us or fill in the form with your location, the estimated tank size and your preferred date. Our dispatcher gives you an indicative price and arrival time straight away.

02

Arrival and on-site assessment

The truck arrives at the agreed time. The driver checks access to the tank, measures the contents, confirms the price and starts work.

03

Sealed pumping of the contents

The contents are pumped into the truck's special tank. The process is fully sealed — no leaks, no odours. Standard truck capacity: 8–14 m³ per load.

04

Flushing and bio-treatment (optional)

On request, the inside of the tank is flushed with pressurized water. EzoSeptik is applied for biological treatment of the system (recommended — it extends the interval to the next emptying).

The contents are transported to an authorized disposal site / wastewater treatment plant. On request we issue proof of disposal (mandatory for commercial clients).

Questions
we get most often

How often should a septic tank be emptied?
It depends on the size of the tank and the number of users. For a family home of 4 people with a 5–8 m³ tank, the interval is typically 1–3 years. Using EzoSeptik bio-product can extend the interval by up to 50%. Signs that emptying is needed: unpleasant odours, slow drainage, overflowing.
How much does septic tank emptying cost?
The price depends on the size of the tank and the distance to the site. For standard domestic tanks (5–10 m³) — a fixed price that includes the call-out, pumping and disposal. For commercial clients on a regular contract — significantly better terms. Free estimate by phone.
How long does emptying take?
A standard 5–10 m³ tank takes 30 to 60 minutes, including access and cleaning. Larger commercial tanks (50+ m³) take several hours or several loads, depending on the truck's capacity.
Do you come out at weekends and on public holidays?
Yes — we work 7 days a week, including public holidays. No weekend surcharge. Emergencies (overflows, blockages) are treated as a priority.
What does 'sealed vacuum truck' mean?
Our trucks have a special vacuum pumping system and a hermetically sealed tank — with no vents through which contents could leak or odours escape. Especially important in urban areas and at sensitive locations (near schools, restaurants, watercourses).
What happens to the contents after emptying?
We transport the contents to an authorized wastewater treatment plant or a designated disposal site (depending on the region). For commercial clients we issue proof of disposal — mandatory for companies that must prove lawful waste disposal.
Can the tank be used straight after emptying?
Yes — after emptying the tank is ready for use immediately. If we apply EzoSeptik bio-treatment, we recommend limiting the discharge of harsh chemicals (chlorine, bleach) for the first 24h, as they could destroy the bacterial culture.
