How much does septic tank emptying cost in Mykonos?

The short answer: it depends on the job, and you get the price first

A load is one full trip of our vacuum tanker, from your property to the licensed facility where the waste is delivered: the licensed municipal wastewater treatment plant of Mykonos (DEYA Mykonou).

Many homes need a single load. Larger villas, hotels and restaurants, or tanks that have not been emptied for a long time, may need more than one. We always tell you the price before we start, so there are no surprises when the job is done.

Below is what actually changes the price, so you can understand your quote and plan ahead.

What changes the price

No two properties in Mykonos are the same. A village house in Ano Mera, a hillside villa above Agios Stefanos and a beach restaurant in Platis Gialos each have different tanks, roads and timing. These are the factors we look at.

• Volume and tank size: the more there is to pump, the more time and tanker capacity the job takes. Our tankers carry 10 to 30 m³, so the size of your tank tells us how many loads to plan.
• Number of loads: if the tank holds more than one tanker can take, a second trip to the treatment facility is needed.
• Access: narrow lanes, steep driveways, low arches and gates that a large truck cannot pass all matter. If the tanker cannot park close, we need a longer hose run, which takes extra time and sometimes a smaller truck.
• Distance from Marathi: we are based in Marathi, in the middle of the island, so most of Mykonos is close. Remote spots on the far side of the island take longer to reach.
• Cleaning versus simple emptying: emptying removes the liquid and sludge. A full septic tank cleaning with washing out and checking the inlet and outlet takes longer.
• Commercial contracts: hotels, villa groups and restaurants on scheduled visits are priced as an agreement, not call by call.

Urgency, out-of-hours calls and the summer season

Our normal working hours are Monday to Saturday, 07:00 to 21:00, and we answer emergencies 24/7. A planned visit fits into our route for the day. An emergency means sending a tanker straight to you, sometimes late at night or on a Sunday, and that can affect the price.

The season matters too. In July and August every villa and hotel on the island is full, tanks fill faster and demand for tankers is at its highest. Planned visits are easier to fit in during the quieter months, and if any out-of-hours or high-season charge applies, we tell you before we confirm the job.

How to get an accurate quote fast

The quickest way to get a reliable price is a WhatsApp message to +30 693 673 2110. You can also call the same number or the second line, +30 693 227 7624. Send us:

• Your location pin from Google Maps or WhatsApp. Many properties in Mykonos have no clear street address.
• A photo of the cesspit or septic tank lid, so we can see the type and size of the opening.
• A photo or short video of the access road and the driveway, including the gate and any tight corners or steep sections.
• The approximate tank size, if you know it. The house manual, the builder or the previous owner often has it.
• When the tank was last emptied, and how many people have been staying.
• Whether you need simple emptying, a full cleaning or help with a blockage.

How to keep the cost down

The most expensive call-out is almost always the one that happens in a hurry. A few simple habits keep costs predictable.

• Schedule emptying before the season, in spring or early summer, when it is easier to book a time that suits you.
• Keep a regular emptying routine. A tank that is emptied on time rarely overflows, and avoiding an emergency is the biggest saving of all.
• Keep rainwater, pool backwash and outdoor showers out of the cesspit where possible, so it fills more slowly.
• Ask guests not to flush wipes, sanitary products or paper towels. Blockages add work on top of emptying.
• If neighbouring properties also need emptying, ask us whether one visit can cover them. We look at each case individually.
• Make the lid easy to reach and keep the driveway clear on the day, so the job takes less time.

Hotels, villa groups and restaurants: scheduled visits

For commercial properties, the cheapest approach over a season is a plan, not a series of urgent calls. We agree visit dates around your occupancy, guest changeovers and the kitchen's quiet hours, so tanks are emptied before they become a problem.

Property managers who look after several villas can group visits on the same day where the routes make sense. Tell us how many properties you manage and where they are, and we will suggest a schedule and a price for the season.

What is included when we empty your tank

Metafores Lymaton Santorinaios has been emptying septic tanks and cesspits across Mykonos for 30+ years. When we come, our driver parks as close as the road allows, runs the vacuum hose to the lid and pumps the tank out. If we notice a problem, such as a blocked inlet pipe or signs that the tank is filling too fast, we tell you on the spot.

Everything we pump out is carried in our tanker and delivered to a licensed facility: the licensed municipal wastewater treatment plant of Mykonos (DEYA Mykonou). Nothing is dumped. You know who is coming, what it costs and where your waste goes.
