The Taman Petanu Water Systems Brief

"Water is Life" - One of the key elements of being "eco" is about where and how we source water, how efficiently we use water, and in what condition water is in by the time it leaves our site. An enormous amount of thought, consideration, debate and design work has gone into developing plans and implementation solutions for the 'best practices' that we feel can be implemented at The Taman Petanu Eco Neighborhood. Currently Plot No 1 is being used as "an experimentation ground" for trialling various options and "myth busting" whether or not they are indeed implementable and cost effective.
