Innovation and sustainability for a better future

A company in rapid development
Over the years, Inrigo has undergone a significant transformation, evolving from an oil and gas sector supplier to a leader in sustainable water and energy solutions.
Founded as PTM Production in 2008, we initially focused on prefabricated mechanical skids for the offshore industry. In 2011, we rebranded as Inrigo AS and established Inrigo Water AS to strengthen our expertise in water and wastewater technologies.
Following the 2014 oil crisis, Inrigo strategically shifted focus to water and energy sectors, leading to a merger between Inrigo and Inrigo Water in 2015. This allowed us to fully dedicate our expertise to tackling global challenges in water supply and renewable energy.
Our international presence has grown significantly. In 2016, we established Inrigo Africa in Cameroon and signed our first turnkey drinking water project outside Norway. The acquisition of STH Engineering AS in 2017 further strengthened our technical capabilities and capacity.
Inrigo deliveres a pilot plant to a Canvasback Winery in Wallawalla, Washington State in 2020. In 2021, we secured a pre-engineering contract, followed by a commercial engineering contract in 2023 with Lamb Weston Holdings, Inc in the USA.
Positioned for growth
Inrigo operates in a rapidly expanding market, where the need for sustainable water and energy solutions is greater than ever. With a scalable and profitable business model, a solid project pipeline, and a commitment to continuous innovation, we are well-positioned for substantial growth in the coming years. Our goal is to be a preferred partner for municipalities, industries, and investors seeking high-quality, sustainable infrastructure solutions.
Through our activities and business operations we shall contribute to UN SDG achievement, focusing on the following goals:
