A greater focus on sustainability from towns and cities of all sizes means drainage designs need to offer biodiversity, amenity, water quantity, and
water quality improvements and ensure confidence that these systems will perform during extreme weather events. This requires creative designs that
include a variation of green infrastructure. These natural details could save a town from flooding, a wastewater pipe from spilling over, or pollutants from running into a nearby river.

In this e-book, we look at the importance of moving from traditional drainage designs to greener, more sustainable systems.
