With more than 100 successfully completed projects, including a large drinking water plant in Cameroon, Inrigo has proven its ability to deliver high-performance solutions in challenging environments. Our expertise in water treatment, wastewater management, and biogas production has made us a trusted partner for municipalities, industries, and governments worldwide.

We are dedicated to providing cost-efficient, high-quality, and environmentally responsible solutions that support a more sustainable future. Our track record demonstrates our ability to execute large-scale projects, adapt to diverse operational needs, and deliver results that meet the highest industry standards.

Inrigo develops and delivers sustainable solutions for water, wastewater, and biogas production, tailored to meet the needs of the future. Our technologies are designed to enhance efficiency, reduce costs, and minimize environmental impact, supporting a transition towards a circular economy.

• Drinking Water: We provide advanced purification technologies that ensure safe and clean drinking water, combined with flexible and scalable systems that guarantee stable supply and low operational costs.
• Wastewater: Our treatment solutions efficiently remove organic material, nitrogen, and phosphorus, while enabling water reuse and biogas production.
• Biogas: Our energy-efficient systems transform food waste, organic sludge, and livestock manure into valuable, renewable energy for heating, electricity, or fuel.

Our solutions reduce carbon footprints, optimize resource use, and contribute to a more sustainable future. By combining cutting-edge technology with a strong environmental focus, we create solutions that are both economically viable and ecologically responsible, aligning with climate goals and ESG strategies.

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.

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.
