Nevertheless, a brand-new study suggests we might find services by studying how the ancient Maya civilization utilized to keep their water tidy.
Keeping water tidy for essential uses like drinking, cleaning, and cooking is a significant international environmental hurdle, complicated by problems such as microplastics and chemical pollution

The Maya excelled at water management. They constructed and maintained water reservoirs that operated as constructed wetlands, utilizing natural procedures such as greenery, soils, and microorganisms to improve water quality. University of Illinois Urbana-Champaign researcher Lisa Lucero believes these might now act as archetypes for how we manage our own water supply.
Wetlands and water
To ensure access to clean water, the Maya utilized a varied variety of aquatic plants, Lucero found, based on proof from excavations, sediment cores, wetlands today, and hieroglyphic and iconographic records. One of the most pre-owned plants is the water lily (Nymphaea ampla), a hydrophytic plant native to temperate and tropical areas.
” Constructed wetlands supply lots of advantages over traditional wastewater treatment systems. They supply a cost-effective, low technology, less pricey and high energy-saving treatment technology,” Lucero stated in a news release. “Constructed wetlands also support aquatic animals and can be a source of nutrients for farming.”
The method the Maya civilization utilized to look after their water resources embodies lessons for present and future water management practices, Lucero argued. If scientists can establish exactly how the Maya reservoirs worked, they may be able to improve existing and future constructed wetlands and broaden their usage, she added.
There are numerous designs available like vertical wetlands, which require less land but more energy to operate.
Settlement maps show that the Maya didnt construct homes near reservoir edges so contamination from human waste wouldnt be a concern for reservoirs. Studies analyzed DNA in sediments from reservoir edges in enormous Maya cities like Tikal in Guatemala and recognized large and small trees. Shaded water from trees avoids algal growth.
Built wetlands do not require the use of chemicals or fossil fuels to operate and after being established they become self-sufficient and self-cleaning with some maintenance. People can work together to supply their neighborhoods with clean water, starting with small built wetlands, likewise planting trees like the Maya did.
” Like Maya reservoirs, constructed wetlands would provide tidy drinking water and support fish, snails, turtles, mollusks, edible and medical plants, and more,” Lucero composed in her paper. “The next step moving on is to combine our respective knowledge and execute the lessons embodied in ancient Maya reservoirs.”.
Lessons from the Maya.
Lucero thinks the Maya utilized impermeable materials such as clay in the tank to support pH levels, permitting water lilies to flourish. And given that many of the tanks were lined with clay or other products, its also most likely that the Maya included soil or took advantage of naturally occurring sedimentation to support water lilies, she included.
Due to the fact that of their frequency, archaeologists had actually assumed that water lilies played a significant function in maintaining clean water. Water lilies are very delicate and just grow in clean water. They do not endure acidic conditions or high concentrations of certain minerals. Water being cloudy or containing too much algae will restrict their development.
Built wetlands are shallow, densely-planted, manufactured pods that filter water through biological and physical procedures. They mimic the functions of natural wetlands however are crafted to treat wastewater, handle stormwater, and even enhance habitat. The idea is to leverage the natural processes including wetland greenery, soils, and their microbial communities to remove pollutants from water.
The research study was published in the journal PNAS.
” Water lilies suggest clean water– and symbolized Classic Maya kingship. Kings and water lilies were portrayed together on significant architecture, stelae, and portable objects,” Lucero composed. “Clean water and political power were inextricably connected as demonstrated by the reality that the biggest reservoirs were developed near palaces.”.
They built and kept water tanks that worked as constructed wetlands, using natural procedures such as plants, soils, and microorganisms to improve water quality. In the case of the ancient Maya civilization, constructed wetlands were utilized for water filtration. Due to the fact that of their prevalence, archaeologists had actually presumed that water lilies played a significant function in keeping tidy water. Water lilies are really delicate and just grow in clean water.” Water lilies suggest tidy water– and signified Classic Maya kingship.
The reservoirs most likely supported diverse biota found today in Central American wetlands that would have benefited the Maya, such as fish and eels. Fish feces, which the Maya would have had to dig up every couple of years, supplied a possible source of fertilizer. The Maya would likewise have actually needed to harvest and renew plants saturated with nutrients.
In the case of the ancient Maya civilization, built wetlands were used for water purification. These early systems were rather effective at cleaning water for drinking, cooking, and other activities.
