World Toilet Day (worldtoiletday.org)

It’s World Toilet Day. This is the day to realize how good some of us have it – we take a pooh in a porcelain bowl and with a push of a button we never have to smell it again. More importantly, it is a day to acknowledge that a large portion of the world does not have this luxury and in fact many people die every year due to faecal contamination. Of the seven billion global humans, 4.1 billion are discharging sewage into the environment without treatment, resulting in environmental degradation and adverse human health effects (Baum et al., 2013).

The goal of sanitation is to reduce the burden of disease and illness-related expenditure, improve water quality, and ultimately result in a higher quality of life (SACOSAN, 2008). Adequate sanitation is defined by the United Nations (2008) as having access to sanitation facilities that isolates the excreta from human contact  (includes pit latrine, latrine with slab; and composting toilet). Unimproved sanitation facilities are flush toilets that are not connected to a sewer, latrine without slab (open pit), bucket, hanging toilet and having no access to facilities (UN 2008).  The delivery of safe and effective sanitation services includes infrastructure (e.g. latrines, sewers), associated behaviors (e.g. toilet usage, hand-washing) and an enabling environment (e.g. public health regulations, fiscal incentive schemes for achieving sanitation outcomes) (SACOSAN, 2008). Currently, 2.6 billion people live without adequate sanitation based on the above definition (Baum et al., 2013). But of the 4.3 billion people using toilets connected to a sewer, 1.5 billion people still have their waste not treated (Baum et al., 2013).  Globally, it is estimated that 64% of people are dumping raw sewage into the environment without treatment (see figure) (Baum et al., 2013).

Contaminated water from inadequate waste management (human excreta, organic and inorganic solid and liquid) results in the spread of diseases and environmental degradation (Baum et al., 2013, Gandhi, 1998, Government of India, 2006, SACOSAN, 2008). The meagre sanitation conditions occurring in developing countries have been directly correlated as one of the leading causes of infant mortality, as well as impacting early cognitive and motor development and undermining educational achievement (SACOSAN, 2008). 

Poor sanitation has been recognized as both a global issue and a global responsibility, and was included in the Millennium Development Goals (Mutagamba, 2003). The 2015 Millennium Development Goal for access to safe drinking water is currently on target, but the sanitation target will be missed by 1.9 billion people (Baum et al., 2013).  The global sanitation situation has been labeled “the silent crisis” since more resources are directed to other, more attractive sectors than sanitation, such as water, health and education (Drangert et al., 2012). Sanitation should be a basic human right, but instead it is used as a means to divide social classes (Mutagamba, 2003). For those with financial means, flush toilets are a luxury that is expected; however, at the other end of the spectrum, finding a safe place to squat is a daily conundrum. Access to adequate sanitation is not only about health but necessary for maintaining personal dignity (UNICEF, 2008).

 

Over the centuries, the resources and technology available to manage human waste products have changed and so have the objectives, e.g. from avoiding stepping in faeces, to controlling smell, to complying with municipal effluent laws (Drangert et al., 2012). The principle of isolating faeces to avoid human contact and to avoid the contamination of drinking water has remained the same over the centuries but, with increased population density, more sophisticated methods of isolation and treatment have been required (Drangert et al., 2012).

As hygiene habits  and local cultural practices differ globally, designing and providing sanitation systems is not a simple fix. Cultural issues around hygiene practices include the feeling of intrusion on a private/personal issue and superstitions, such as believing that toilet use may lead to fertility problems (Mutagamba, 2003). Flush toilet are still seen as the gold standard around the world (Drangert, 2003), signifying class and wealth so that even in water-stressed areas, such as South Africa (Republic of South Africa, 2011), people want flush toilets. Such inclinations need to be taken into account when trying to improve access to adequate sanitation.

As most of you know, I like toilets. And my team of colleagues and I, here in Sweden, have entered a competition to design a urinal for emergency situations (waste.nl/en/design-contest) – the urinal has to be quick to put up and easy to use. Ours is called the Sani-Dash and is designed Sani-Dash: urinal for emergency situationsspecifically for women.

Please vote today at waste.nl/en/design-contest
(ours is the Sani-Dash, but obviously vote for the best!)

 

Thanks for you all your support – we tied for first!
