Greywater-Harvesting Plumbers & Landscapers

See below for both installers of in-house greywater plumbing and landscapers familiar with greywater harvesting who can design and implement the associated planting, earthworks, and outdoor plumbing…

If services are not specified, contact the provider for details of what they offer.

Note: the better you understand what you need – the better. That way you can convey this to those you hire, and better ensure they do things right. That’s why I highly recommend you read the greywater-harvesting chapter of “Rainwater Harvesting for Drylands and Beyond, Volume 2, 2nd Edition” by Brad Lancaster and “Create an Oasis with Greywater” by Art Ludwig before you begin.

Note that I find gravity-fed, tankless  greywater-harvesting systems, such as the “branched drain” system are the lowest maintenance, least expensive, and most efficient greywater systems. These are the systems advocated and described in the books above. Make sure the designers or installers you hire are familiar with these systems along with greywater stubouts.

Tanks and pumps significantly increase cost and maintenance.

For just the harvest of laundry washing machine greywater, make sure you and your installers are familiar with BOTH the gravity-fed “multi-pipe” drain system fully described in the greywater chapter of Rainwater Harvesting for Drylands and Beyond, Volume 2, 2nd Edition, and the laundry to landscape (L2L) system fully described in Art Ludwig’s “Create an Oasis With Greywater”, which uses the washing machine’s pump and gravity. Depending on you site, one or the other may be your best option.
