I also work in the construction industry and used to have a headache when implementing drainage systems, because customers often do not understand the importance of this system. In my opinion, to increase awareness, you should focus on educating the market through content: sharing the Incredibox consequences of not properly handling drainage, real case studies... Make a professional website, easy to read, with before-and-after construction images. And don't forget to optimize SEO according to local keywords – like 'construction of drainage system in District 9', for example.
