Gasometer replacement project in Chile for Aguas Andinas (Veolia group)

Gasometer replacement project in Chile for Aguas Andinas (Veolia group)

Micreau Chile, together with its parent company Micr’Eau SAS in Paris, won the contract to replace a Sattler gasometer with a storage capacity of 1,040 m³ of biogas.

This unit had recently become inoperable and was therefore replaced with an identical model to enable the 500,000 population equivalent wastewater treatment plant managed by Aguas Andinas to regain its storage capacity within a few months.

Micr’Eau, which had already carried out an initial modernisation operation on the flaring system with the installation of a Hofstetter unit, confirmed its technical commitment to the largest private operator in Latin America (5,000 employees working on drinking water and wastewater around Santiago, Chile).

Micr’Eau took advantage of the summer of 2025 to modernise the biogas line (flare and gasometer) alongside operator Veolia in Lille.

We began by dismantling the two VSO gasometers that had been in place for around ten years, then replaced them with two new 3,800 m³ storage tanks manufactured by Sattler/Agrotel.

This operation was carried out without interrupting production during July and continued into September with the upgrading of the existing flare.

We would like to remind you that Micr’Eau is the only company capable of working on Sattler, VSO, BSDV, Ecomembrane and Ecothane gasometers in France and internationally.

It also represents the world-renowned Hofstetter flare brand.

First Micr’Eau project with the SAUR group on its biomethanisation line in Montauban to equip the biogas storage digesters. An acrobatic project, since the equipment will be located more than 10 metres high and will cover two structures 16 metres in diameter. We’ll be back next month when the work is completed.
