Today, China remains the most populous country in the world, with 1.4 billion inhabitants. That’s 18.4% of the Earth’s entire population in just one country. India’s following closely behind with a population of 1.3 billion inhabitants, followed by the United States and Indonesia.

As a planet, we face many consequences due to the ever-growing human population – habitat loss, the loss of natural resources and global warming. But how is population growth affecting our sewer systems?

The Earth’s warming atmosphere holds more water, which in turn causes more rain. This, in conjunction with the increase of impermeable surfaces, due to rapid urbanisation to keep up with the growing population, guarantees that surface water flooding is likely to become a bigger issue as our drainage systems won’t be able to cope with the excess water load.

What can we do to prevent this flooding?

Sustainable drainage systems are a sequence of water management practices that aim to closely imitate natural drainage processes. After intercepting excess surface water, SuDS store it temporarily so that it has time to infiltrate into the ground, evaporate or be discharged safely into a nearby watercourse so that it can be reused.

Sustainable drainage systems protect against flood risk by controlling the flow and quantity of surface water runoff to prevent flooding and pollution of the sewer network.

SuDS take the pressure off our overloaded sewers by stopping excess water from entering the network and being processed unnecessarily. We can then think of sustainable ways to reuse the captured water for example to our clean cars or water our gardens, which would help in water-stressed areas around the UK.

Ensuring we minimise the effects of climate change can also help us to avoid major flooding incidents. Even simple things like buying organic, local produce, using public transport and recycling can help to make a difference.
