This was not the intention, but due to the removal of the old foundation remains and old sewer systems from the bottom of the site (you can read more about this here), there is no longer any proper drainage of the large amount of rainwater of the past few months. In anticipation of the future permanent use of the area, a solution to this drainage problem is now being sought. This is expected to take several months.
Fortunately, this will not have any consequences for the immediate environment. If you still have questions, you can send them by e-mail to Info.BCD@biotechcampusdelft.com.
