In 1993, the UN designated March 22nd to be known as World Water Day to bring awareness and change to those who have limited access to clean water in addition to how we can improve water security. This year's theme is "wastewater" and focuses on the reduction and reuse of wastewater to achieve the Sustainable Development Goal 6 targets, some of which include:1
- By 2030, achieve universal and equitable access to safe and affordable drinking water for all
- By 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations
- By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally
Globally, more than 80% of wastewater (from sources like homes, cities, and industries) gets sent to lakes or rivers without treatment or being reused leading to pollution and diminishing of nutrients. We can reuse greywater from homes for watering plants and reuse city water for irritation or cooling systems. This is why each stage of wastewater treatment systems must be effectively managed and treated - so that water can be reused.
As population and urbanisation increases on a global scale, the generation of wastewater will increase. The global demand for water, by 2030, is also expected to grow by 50%. Furthermore, 663 million people today still lack improved drinking water sources. Low-income cities tend to discharge their wastewater without treatment. Motor garages and other industries also tend to dump toxic chemicals into the wastewater system.
We look forward to World Water Day this year and being a part of the water monitoring industry to improve water quality worldwide.
