Ecology Action | Greywater pumped and filtered | Single family residential | Scotts Valley | Santa Cruz | CA |
| 172 | 1 week | Advanced Waste Water Systems, GreyFlow Plug and Play Short installed to pump greywater from master bathroom shower, second shower/bath, and laundry through Metzerplas 2.6 GPH dripline to two irrigation zones (CA native wetland and fruit trees) | This system was completed in conjunction with a whole-house remodel. It was the perfect time to work with the plumber on making sure the 3-way diverter and greywater pump unit electrical were placed in the correct position to overflow into the building's existing existing main drain line to septic system. An RPZ backflow device was required at the house meter, adding an additional $1K in costs. | |||||||

| 468 | 2-3 business days | Greywater collected via diverter valve & check valve into in-ground fiberglass basin with bag filter & submersible pump, pumped through glass media filter in fiberglass housing, with manual 3-way backflush valves, to drip irrigation. | 2016 CPC Ch. 15 | |||||||
Love's Gardens | Greywater pumped and filtered | Single family residential | Santa Cruz | Santa Cruz | CA |
| 550 | 1 month or more | Aqua2use system with Grey-Flo drip irrigation. Three showers, 2 sinks, and laundry. Note: the permit fee listed at $550 includes the inspection. Did not have final documents for this in our records. | Used Central Coast Graywater Alliance Permit Template, June 2015. A lot easier than previous. Ending the Environmental Health, Zoning, and Building visits to just Building Counter reduced visits and working with Jim Heaney who understands reduced time spent obtaining the permit. |
