ACTIVE APPROACHES FOR HARVESTING RAINWATER AND GREYWATER
By “actively harvesting” rainwater and greywater, we are referring to formal systems for collecting, filtering, storing and recycling water that would otherwise be sent to municipal sewer systems. Proper filtering and storage of harvested water are required to prevent the water from turning septic in storage – which could result in off-colors and odors. Local codes may or may not be in place that set standards for the required purity of stored water.
While these systems are more complex and more expensive than passive systems, they have the advantage of reducing the costs for municipal water and water treatment. It is considerably more expensive to retrofit these systems in existing buildings – particularly greywater systems that require separate internal plumbing. Rainwater systems can be more easily added if they are planned for irrigation or specialty uses, and there is adequate space available for the processing and storage systems.
