Mellifiq’s Innovative Drinking Water Plant in Östersund
Introduktion.
A complete EPC project for a decentralized full-scale drinking water plant
In this reference project we are heading up north to the municipality of Östersund in Sweden, to design, build, and commission a complete drinking water facility. This facility will be specially adapted to meet drinking water standards, handle challenges posed by the climate and ensure a safe and reliable long-term water supply for the community.
Problemet.
Östersund municipality identified the need for a decentralized drinking water plant in Häggenås to address insufficient capacity in their existing supply and enhance the drinking water quality and secure the local water supply in the area.
The project involved more than just constructing and designing a treatment process; it included comprehensive planning, design, extensive civil works, and installations of all process equipment.
Mellifiq’s expertise in water treatment technology and capacity to provide tailored, innovative solutions was a perfect fit for the case.
The new drinking water plant needed to accommodate drinking water for the surrounding urban areas with a large buffer capacity. The facility had to be constructed in compliance with Livsmedelsverkets (The Swedish food agency’s) regulations ”LIVSFS 2017:2” for drinking water and associated materials to ensure safe use.
Lösningen.
The planning of the facility included process design, architectural planning, permit applications, and geotechnical investigations to ensure the ground’s suitability for construction.
During the engineering phase, all aspects of the project were planned, including electrical systems, building construction, water and sewage systems, and equipment for the water purification process. The facility’s appearance was designed to blend in with the area’s character in mind to harmonize with the surrounding environment.
The project involved managing all practical aspects, including civil works to prepare the construction site, laying the foundation and erecting the building.
Existing boreholes were used for raw water, which were upgraded with new pumps and infrastructure to improve extraction and treatment efficiency. The treated water is then either stored in an underground reservoir or supplied directly to the water network.
Besides the water supply to the drinking water treatment plant, there is utility water with a water heater. This water supply provides toilets and kitchens with water and an emergency shower due to the handling of chemicals in the building.

Facility specifications:
The core of the facility includes a water treatment process hall equipped for purification and related operations.Additionally, the facility features a personnel pentry and restroom. An internal water system, which passes through a water heater, supplies water to the pentry, restroom, and an emergency shower, essential for handling chemicals within the facility. The roof is specifically engineered to handle heavy snow loads typical to the region and designed for possible future installation of solar panels.
Utvärdering.
In this project we successfully delivered a complete and customized water supply facility, demonstrating our expertise as a leading EPC (Engineering, Procurement, and Construction) contractor. The project highlights our commitment to providing high-quality, secure drinking water solutions globally.
The facility integrates turn-key technologies, including Water Maid membrane filtration och Saniray UV disinfection. The membrane system includes a CIP system with a water tank and a dosing system with scale inhibitors to rinse the membrane system if needed. The system is also equipped with advanced automation and control systems that enable real-time pressure monitoring and maintain stable operations. Strategically placed sampling points throughout the facility enable comprehensive quality assessments.
The success of this vital work underlines the significance of strong partnerships. By integrating sustainable practices and material choices we strive to minimize our environmental footprint and ensure that the water supply in Häggenås meets the community’s needs for many generations to come.
