laundry-to-landscape systems use your washing machine's internal discharge pump to help distribute water through the yard. a diverter valve is installed behind the washing machine, allowing greywater flow to be directed to either the landscape (normal use) or to the sewer (if for example you are running a load with bleach). the pump provides positive pressure which can be used to run the water long distances horizontally or even slightly uphill. it also simplifies irrigation lines, allowing for a single main line supplying multiple irrigation branch lines. this type of system is easy to adjust flow levels to different irrigation basins, and fairly easy to modify to accommodate new landscaping. it can be used on flat lots and in homes with no access to plumbing, such as slab-on-grade houses. it is generally trouble-free and easy to maintain. |
