There are only a few days left until the end of the collection on the Hithit portal with the aim of raising money for an expanded reprint of the Water in the City methodology, which is dedicated to sustainable management of rainwater. Contributors can choose from a range of rewards from the publication itself to consultancy, courses and workshops.In addition to the publication itself, contributors also receive other rewards, especially in the form of further advice and education in the field of rainwater management, which are especially suitable for representatives of cities and municipalities."Rainwater management in connection with green infrastructure is the basis of every modern city. Therefore, any publication that deals with this topic is welcome. Especially one that takes this issue as a whole in a broader context, is easily usable in practice, and is also graphically attractive and clear."
