Remote Toilet Challenges
Responsibilities and retrospective thinking

When we enjoy the beauty of our mountains, our last intention is to damage their fragile environment. But, whether on a day walk in the Highlands or a trek in Nepal, we have all been caught short up a mountain, or been tempted to leave that biodegradable apple core or banana skin behind.
Sadly 'biodegradable' is not always good for the environment. The higher up the mountain the more difficult it is for life to cling on there, so the less bugs there are to eat your deposits. On busy routes and passes, poo and litter builds up and becomes a big problem. This is particularly bad in really high tourist hotspots like Mount Fuji in Japan and the popular trekking routes in the Himalayas, but is an unpleasant problem on well-walked paths in our local mountains.
Closer to home, it is not uncommon to find flush toilets in bothies that run out, untreated, into the nearest loch or burn.
Untreated poo doesn't just spoil the natural environment; it can make us very ill. There are a variety of diseases that are related to sewage ranging from E. coli, Salmonella, Cryptosporidium and Enteroviruses: the symptoms of these range from mild stomach upsets, to vomiting, acute diarrhoea and even death.
This disgusting problem is easily remedied without connecting the most remote crags and high passes to a mains sewage supply. Low-tech solutions are cheap, easy to build, environmentally friendly and more hygienic.
The Centre for Alternative Technology (CAT) helps people find the most appropriate sewage solutions for mountains and other isolated locations. CAT is itself remote, located in the beautiful Cambrian mountains of Mid-Wales. We have no mains water or sewage, so treat all our drinking water and sewage independently without using energy or chemicals (no mean feat as we have 1000 visitors a day in summer). We have worked on projects as far flung as the Indian Himalayas, Mount Fuji in Japan and Thurso!
CAT worked with Palenquin Travels, a trekking company who lead tours through the Zanzker Valley in the Himalayas. As the popularity of their route increased, the environmentally aware company became very concerned about the quantities of poo that was generated. Up to 3 groups of 20 people were camping in one location every night for the whole season. That's 60 poos a day for 4 months = over 7000 poos! These were liberally spread all over common land, so barefoot Zansker children often became ill from contact with foreign bugs that they are unaccustomed to.
CAT designed a compost toilet that was sensitive to the local environment and to the local culture to be built at the most popular campsites. Young volunteers installed this last year with help from Palenquin.
Closer to home, we designed a reed bed system for the Pinnacle Club (the only women's mountaineering club in England and Wales) at the base of Snowdon. The design combined a traditional septic tank with twin reed beds that is working well after 4 years in use. We also designed a very clever system for an isolated house in the wilds of the Scottish tundra that included a solids separator and composting unit, so it is a flush compost loo! Easy to empty and with a nice product to enrich the poor acid soils of the garden.
Ecology and sustainability are our underlying principles. We find it frustrating that in high mountains with many visitors, facilities are sometimes discouraged for aesthetic or conservation reasons, and hugely damaging toilet systems are installed (like the New Zealand model of flush toilets with helicopters to ship the waste away!), rather than environmental protection. If we are prepared to damage these areas with our mere presence, then we should be prepared to repair the damage in the most environmentally responsible way, even if this means sticking a compost toilet on a mountain pass.
CAT was set up in a disused slate quarry in the 1970s by a group of committed environmentalists. They formed a community to experiment with new, green technologies. Almost thirty years later, their pioneering dreams have grown to become Europe's largest eco-centre, gaining a worldwide reputation as one of the leading organisations demonstrating and advising on ecological technologies and lifestyles.
Our mission is to inspire, inform and enable people to explore new ways of living. We have a visitor centre aimed at all age groups, with a wide range of interactive displays that provocatively address the environmental aspects of our lifestyles and the steps we can take towards greener living. Each year 70,000 visitors come to look and learn. CAT especially encourages visitors to use sustainable transport - there's even a discount if you arrive by train, bus, cycle or walk (it's a long walk from Scotland).
