ECO SEPTIC TANKS

Eco Septic Tanks based in the Vall De Pop specialises in installing domestic environmentally friendly CE marked and certified Eco-Biological waste water treatment plants in the North of Costa Blanca. The towns and villages we cover include: Moraira, Benissa, Pedreguer, Benigembla, Benitachell, Pego, Alcoi, Gandia, Oliver, Orba valley, and the Jalon Valley that includes Parcent, Lliber, Alcalali and Murla.


If you have an old septic tank in Costa Blanca North it will most likely not meet current regulations and needs to be upgraded by law, and you will not be able to buy or sell a property in Spain without an eco bio septic tank upgrade. Common reasons for upgrading your old septic tank would be to obtain a Habitation Certificate or cédula de habitabilidad. This certificate means that the Spanish property complies with the town hall's habitation requirements and old septic tanks do not.


Our eco friendly bio septic tanks also know as oxidisation tanks have six filtration chambers to make sure the water disposed of is totally safe for the environment whilst being fully accredited by the water board and town hall. You can use this grey water for irrigation on request.


Our English owned company strives to help Ex-pats find an eco environmentally friendly green solution to outdated unhygienic waste water disposal systems in the whole of Costa Blanca North, covering all inland villages and coastal towns from Xalo (Jalon) to Gandia and all the way to Valencia.


Our dedicated English speaking Spanish workforce have extensive experience and expertise to professionally install domestic waste water treatment plants efficiently at fair prices. Our architect liases with your Town Hall to obatin a work licence and necessary paperwork required.




Wonky Veg  

Unlike other Treatment Plants, our sustainable Septic Tanks have got the CE Certificate, Environmental Certificate, TÜV Certificate and the approval of the Hydrographic Confederation of the Segura, all needed for your local Town hall and administrations.

As you may be aware the EU nation laws states that all properties, that are NOT connected to mains sewerage, need to have an eco certified Septic Tank installed, replacing the old /existing non conformed Septic Tank Pit or Soak Away, otherwise known as a “posa negra” or black hole.

The waste from these old types of installations is allowed to soak away into the surrounding soil causing a negative reaction to the land and animals habitats. Of course this is against current European regulations in the Valencian region and an approved eco septic tank needs to be installed.

We are not only talking about rural countryside properties, but also urban properties not connected to the mains sewerage in areas such as Benissa and Calpe.

Our Eco Septic Tanks, also called Oxidation Tanks, are required by the administrations (Town halls) to obtain any legal required documents, such as a Responsible Declaration of Habitation Certificate (The Old Occupation License), this is very common when purchasing or selling a villa or finca in rural locations.

The eco-friendly waste water process needs micro-organisms to brake down and use organic pollutants from wastewater for their nutrition, thus cleaning the wastewater before it’s extracted to the land. This biological cleaning method is based on bacterias ability to feed from various organic and mineral substances from wastewater. Oxygen is also essential for vital activity of bacteria, therefore an air blower is hard wired near the wastewater treatment plant.

2022 EU REGS


No matter if you are buying or selling a property on the campo the valenciana government say you must meet the 2022 regulations for septic tanks before any sale can be agreed. Even if your property has a Habitation Certificate it will not change the situation. 

You will not be able to market or buy a property with an estate agent unless you have a certificate showing that you have had a new approved bio septic tank installed. 

Tip: If you’re wanting to purchase a property it is likely the seller will pay half the cost with you or offer you a discount, ask your estate agent to negotiate this on your behalf.
