Dr Christopher Walker has been employed at Covey Associates, an engineering consultancy, for over 17 years and is a Director of the company. Dr Walker is also a co-inventor of the Clarity Aquatic floating wetland system, a company which provides floating wetland technology for a variety of needs (e.g. water treatment and habitat). Chris has designed a range stormwater treatment systems for numerous residential, commercial and industrial projects in Australia and abroad. He has been involved in stormwater research for over 20 years, working with numerous Australian and International Universities. Chris is a world-expert in the use of constructed floating wetlands (CFWs) for water treatment and has developed several novel designs and applications of this technology.
