The system alone costs $3970 - $4530 with an installation fee of $1320. Then, maintaining the system costs $200 to replace the membrane filter each month. Systems like these are recommended for commercial properties or hospitality like guest houses or hotels. Constructing a DIY greywater system is a lot cheaper. The branched drain system was also invented by Art Ludwig. Greywater in this system flows through standard (1 1/2″ size) drainage pipe, by gravity, always sloping downward at 2% slope, or 1/4 inch drop for every foot traveled horizontally, and the water is divided up into smaller and smaller quantities using a plumbing fitting that splits the flow. Concerns about decreasing urban water supplies and environmental degradation caused by existing water infrastructure have prompted research on more resilient and long-term water delivery systems. Greywater reuse has been proposed to expand local water supply portfolios while minimizing stress on existing ecosystems and infrastructure.
