Auckland City's stormwater web pages are for householder, student or teacher, developer, engineer, architect or trades professional - plumber, builder, drain layer or concrete contractor. Rapid growth, aging pipes and increasing environmental awareness mean we need to change the way we manage stormwater in the city. These pages show how we can all help to protect our streams and beaches and extend the life of our infrastructure while avoiding major public costs.
