Technology
Very often, construction site water treatment is carried out using mobile equipment and potentially utilizing a sedimentation basin.
- In 2025, we treated approximately 300,000 m³ of construction site water with our mobile rental equipment.
- We are also frequently responsible for project design, equipment operation, maintenance, and monitoring.
Experience and Expertise
Our construction site water treatment technology is often based on chemical precipitation and sediment settling. The design of our methods is built on over 20 years of experience and the expertise gained from hundreds of water treatment projects.
The solution is also frequently modeled in our own laboratory, or we solve on-site challenges on an express schedule. Our rental fleet and material inventory guarantee flexible and rapid response to the often changing situations on site.
Advantages of Our Service
Regulations Regarding Construction Site Water
Construction activities generate construction site waters or sludge from rainwater and meltwater, groundwater, and water used in work methods. These waters and sludge must often be removed from the construction and renovation site.
Discharging construction site water outside the property or plot boundaries often requires a notification or a permit. In addition, separate permits and regulations often apply to water discharged from contaminated land.
Construction Site Water Guide
The party initiating a construction project must draw up a construction site water management plan and comply with it. Water discharged from the site must be purified and treated so that it meets regional or site-specific limit values.
