Water is one of our most precious natural resources. Although it appears that we might have a lot of it in Wales, we need to carefully manage this resource. Most of CAT's water comes from a reservoir above the Centre and run-off from the surrounding valley. The rest is collected from the roofs of our buildings - we don't have a mains source. As water flows through CAT we use it for generating energy and running the cliff railway, for watering plants, for providing habitats for wildlife, for drinking, cooking and washing and for our low-flush toilets.
Some of the water can be used direct from the reservoir, such as water for power and water for plants and washing. For the water we consume we use a chemical-free purification process. The water initially passes through a sand filter, which removes any larger particles. Any biological impurities in the water are digested by naturally occurring bacteria and algae which colonise the filter. The water is then fed through a UV filter to finalise the purification process.
There are a range of water conservation methods around the site. We have compost toilets, waterless urinals or low flush toilets, water-saving nozzles on the taps and displays to demonstrate how you can reduce water usage in your home and garden.
Interactive exhibits on site demonstrate how we can tap into the water cycle to generate power either through harnessing the energy of water as it flows downhill or by using tidal power. CAT uses two water turbines to generate power. The Pelton Wheel on display can generate 4kW power at 240v. There is also a working model which shows how the turbines work.
