1979

Founder Leif Rønsen brings back the idea of treatment of sewage from low-density residential areas after a trip to the United States. On Kapellveien in Kolbotn, work starts on the development of Biovac domestic systems, something that would turn out to become the basis for onward developments as these systems quickly became a market leader in the industry for several decades.

1982

Biovac AS is formally setup as a company, production is increased and work on marketing the solution to both customers and sewage treatment authorities becomes a priority.

1983

Biovac AS moves from Kolbotn to Noractor-gården at Sørumsand.

1985

On the basis of NIVA and Aquateam's test reports SFT recommends the Biovac solution as an alternative to conventional sand filter systems. Based on this recommendation, SFT also proposes creating a centralised certification scheme for mini treatment systems. Since June 1986, this scheme has been a useful tool for manufacturers, customers and sewage treatment authorities. The certification was the national standard until it was replaced by the European standard EN 12566-3 in August 2008.

1986

Since the start, approx. 1,900 mini treatment systems have been put into service across large parts of the country. In addition, production of larger treatment systems (SBR systems) commences.

1989

Biovac presents a new generation of mini treatment systems ready for the market - based on SBR technology. These systems are called FD systems (Fill and Draw), and are today produced in the sizes 5pe – 35pe.

1992

Biovac builds SBR systems at Hornindalsvatnet – Europe's cleanest lake. Two more projects follow for the same lake in xx.

1992 is also the year in which Biovac celebrates its 10th anniversary.

1996

Biovac AS is acquired by the environmental technology group Goodtech ASA which is headquartered in Sandefjord. Administration and production continue at Sørumsand.

”Although it is a big investment for a small municipality, it is important to safeguard the assets that clean water will provide us with in the future,” says Jarle Tvinnereim in the Municipality of Hornindal.

1998

Biovac builds the new central treatment plant for the Municipality of Tvedestrand, Norway's largest biological treatment system based on SBR processes. The system has a capacity of 5,000pe and is equipped with a filter system for the aftertreatment of slurry.

2000

Biovac again presents a new generation of mini treatment systems, this time systems for burial. The systems are called FD (Fill and Draw) and N (Nedgravd = Buried). The system becomes a great success and still forms an important part of the company's growth.

2007

The subsidiary Biovac Sverige AB which is headquartered in Gothenburg is set up to handle an ever-growing market for small and medium-sized sewage treatment systems in Sweden.

2008

Biovac's mini sewage treatment systems are certified in accordance with the European standard (EN 12566-3) which replaces the national certification scheme. Biovac also signs the company's largest single contract with the Municipality of Odda to expand its Håra and Seljestad sewage treatment system.

2009

Biovac merges with its sister company Fluidtec and undergoes a reprofiling under the auspices of its parent company Goodtech ASA. Biovac's new name is now Goodtech Environment Sørumsand AS. Biovac lives on as a product name and the company remains the same.
