The investment rate in Sweden’s public water and wastewater systems have increased in recent years due to an increased need for renewal and replacements of older systems, as well as for new investments in pipe systems, pumping stations, water works, and water treatment plants. In 2017 about 12 billion SEK was invested in the public water and wastewater system in Sweden. The investment rate needs to increase to about 16 billion SEK per year over the next 20 years in order to ensure the quality of the drinking water supply, wastewater treatment, and stormwater management. The public water and wastewater systems are owned by Sweden’s 290 municipalities. Both because of the higher investment rate as well as the many water utilities, that vary largely in size and resources, there is a demand to ensure a systematic and qualitative project cycle for investment projects that are quality assured, cost-efficient, and meet time plans and project budgets. The main objective of Projekthandboken VA was to map a general project process that can be implemented by water utilities in Sweden for drinking water, wastewater, and stormwater infra-structure projects. The book gives practical advice for the project manager and the project team in order to assure the quality of the project cycle for the design, procurement, implementation, and evaluation phase.
