Top 3 Mistakes Made by Greywater Amateurs
 Storing greywater. Greywater becomes septic after a couple of warm days and that creates anaerobic slime, which eventually clogs up any kind of filter, even a sand filter, and then the downstream emitters. ReWater’s controller directs our system to use greywater as its produced, starting and stopping when greywater is or isn't available, keeping it fresh and full of oxygen. This is best for the system and the plants in the short term (filter efficiency) and long term (emitter life). You're planting permanent landscape, so you will need ReWater's long term solution.
 Using conventional drip emitters. Even highly filtered greywater downstream of the best filter system has tiny organic solids that combine with the minerals found in the source water to create “scaling” on the inside of pipes and irrigation tubing. Those "scales" grow until they flake off over time and then flow downstream to clog all but ReWater’s large-orifice emitters. ReWater's pumps' surging action scours the insides of those pipes and tubes with its brief but high volume “dosing” of the irrigation valves, ridding the pipe and tubing system of any scales before they get too large to pass into the soil. Before you use any other emitter, ask the manufacturer to show you examples of a legal greywater irrigation system (one that is used underground) that has been in use for more than 5 years. They can't.
 Using a gravity-fed irrigation system. In a gravity-fed system, water flows to the lowest point and pools there. You can try to engineer the system and regulate the flow with hand valves, but unless you’re just irrigating a few trees or hedges or something else with a high degree of tolerance for error, you will be very disappointed with that type of “irrigation” pattern.
