We are currently facing unprecedented water scarcity, compounded by multiple water supply problems caused by climate change. If we want to secure the future of our planet, we must address water sustainability.
We have been assuming for centuries that there is enough to go around. After all, more than 70% of the Earth’s surface is covered in water. However, only 3% is sweet and, therefore, suitable for human consumption and industrial use. Furthermore, only 0.5-1% of fresh water is available, meaning it is not locked up in the polar caps, in the atmosphere or in the ground. Water has become so scarce that it has recently become the “new” oil.
Yet we are still failing to sustainably use this important resource. A very clear example is the loss of water that occurs due to leaks or failures in the network, and which in Spain is around 25%.
Added to this is the increase in water consumption. According to the United Nations, this has multiplied by six in the last hundred years, growing at a rate of 1% per year, due to economic development, demographic growth and our consumption habits.
In these circumstances, it is clear that the water and wastewater sector has a crucial role for sustainability goals.
