Managing water flow across an entire urban area creates serious problems. Hard surfaces, ageing pipes, and growing city populations all make it harder to control flooding and water quality.
Real World
In Greater Manchester, Victorian combined sewer systems built for a population of one million now serve over 2.8 million people; during heavy rainfall, the same pipes carry both sewage and stormwater, frequently causing combined sewer overflows into the River Irwell.
