Construction site stormwater management
While monitoring the water quality in urban streams in Turku city since 2011, we noticed that a significant proportion of pollution loading was originating from construction sites. Even though one project lasts for a limited time period, at any given time there are numerous construction projects of different sizes ongoing in the city. At that time, in Finnish cities there was generally still no water management requirements for construction sites. In 2014 we started collaboration with the cities of Kaarina and Turku with the aim of getting more information of the actual loading from different types of construction activities as well as developing tools and training for cities to reduce the negative impacts of construction activities on urban water bodies and existing infrastructure. Since then, we have continued the work within several different projects.
Results so far from the projects:
- Construction site stormwater management guide for construction companies: Työmaavesien hallinnan ohje rakennusalan ammattilaisille (In Finnish) & Työmaavesien hallintarakenteet (In Finnish)
- A study of loading of hazardous substances and mitigation measures from demolition sites: Purkutyömaiden työmaavedet ja niiden hallinta 2021 (Master’s thesis)
- A study on mitigation measures of infrastructure construction sites in clay soils
- A construction site water management guide for Turku city: Turun kaupungin työmaavesiopas 2017 (In Finnish)
