According to the UN report on Water, Sanitation, and Hygiene, today, 2.2 billion people lack access to safely managed drinking water services, and 4.2 billion people lack safely managed sanitation services. Unsafe hygiene practices are widespread, compounding the effects on people’s health. The impact on child mortality rates is devastating, with more than 297 000 children under five who die annually from diarrhea diseases due to poor sanitation, poor hygiene, or unsafe drinking water.
In this regard, Ayala has developed a sustainable, portable integrated solution for stand-alone toilets or a cluster of toilets, wherein the water used is treated in an adjoining natural treatment system and can be reused for irrigation purposes/other.
This neat and compact system logically closes the loop toward the toilet being a zero-discharge unit while saving water and nurturing gardens/surroundings.
The conventional systems used today, usually chemical toilets, are cumbersome solutions since they require maintenance; they typically have a relatively small tank, which needs to be emptied frequently; they are not connected to a sewage system, so contents have to be transported to a treatment plant. Chemicals used in these systems may be toxic and difficult to dispose of safely. In addition, these systems are expensive, often suffer from sewage smells, and may be perceived as unpleasant or ugly by many communities.
Ayala’s system, which is a natural ecological system, recycles and reuses water.
As you can see below, the system includes a water tank on its roof, which needs filling every 3-4 weeks. It consists of a septic tank, which is sufficient in size and does not need to be pumped/emptied, so there is no additional pumping or transporting costs. Waste from the toilets, including toilet paper, breaks down naturally in the integrated system. No energy or chemicals are required, and maintenance is negligible. Output water is of excellent quality; can be used efficiently for agriculture, gardening, or recharge to aquifer; the systems are adapted to the site’s conditions, enhancing and beautifying the landscape and providing an excellent aesthetic solution. There is no exposed water in any stage, avoiding the risk of exposure to pathogenic elements or drowning; the system’s end stages contain a particular unique, and dedicated substrate, eliminating any pathogens residues before discharging back to nature.
Water, Sanitation, and Hygiene
The benefits of having access to an improved drinking water source can only be fully realized when access to improved sanitation and adherence to good hygiene practices. Beyond the immediate, obvious advantages of people being hydrated and healthier, access to water, sanitation, and hygiene – known collectively as WASH – has profound broader socio-economic impacts, particularly for women and girls.
The fact that WASH is the subject of dedicated targets within the Sustainable Development Goal (SDG 6) is a testament to its fundamental role in public health and, therefore, in the future of sustainable development.
Indeed, access to safe water and sanitation are human rights recognized in 2010 by the United Nations General Assembly. For universal fulfillment of these rights to become a reality, we will need the suitable systems: well- resourced, capable institutions delivering services and changing behavior in resilient and appropriate ways.
Without improved sanitation – a facility that safely separates human waste from human contact – people have no choice but to use inadequate communal latrines or to practice open defecation. For women and girls, finding a place to go to the toilet outside, often waiting until the cover of darkness, can leave them vulnerable to abuse and sexual assault.
In the immediate environment, the exposed fecal matter will be transferred back into people’s food and water resources, helping to spread serious diseases such as cholera. Beyond the community, the lack of adequate waste disposal or sewerage systems can contaminate ecosystems and contribute to disease pandemics.
The impact of universal access to WASH on global health would be profound. There is the potential to save the lives of the 829,000 people who currently die every year from diseases directly caused by unsafe water, inadequate sanitation, and poor hygiene practices. We could also drastically reduce child malnourishment and help alleviate physical and mental under-development. Today, 50% of child malnutrition is associated with unsafe water, inadequate sanitation, and poor hygiene. Women and girls would have the facilities and knowledge to manage their menstrual cycles safely and safely. Similarly, during pregnancy, childbirth, and postnatal care, medical staff, expectant mothers, and their families will be better equipped to ensure that newborn children are given the safest and healthiest possible start.
In urban areas, for every $1 invested in primary drinking water, an average of more than $3 is returned in saved medical costs and increased productivity. For every $1 invested in basic sanitation, the return is $2.5. In rural areas, the return on investment is even higher: with every $1 invested in primary drinking water, an average of nearly $7 is returned in saved medical costs and increased productivity. And in the case of basic sanitation in rural areas, every $1 return on average more than $5 in saved medical costs and increased productivity. (Hutton et al. 2015)
