  • Is collecting rain legal?
    Yes! In fact, there are local rebates available that help pay for your rain collection system! Find more info here!
  • Is a rain garden required for overflow?
    While rain gardens are not required for rain tank overflow, we highly encourage our clients to work to form their landscape to serve to slow down the excess water. The reality is, during the rainy season, it will rain more than you can catch. Creating rain gardens and swales serves as an extra step to keep this water in your local ecology and out of the sewer.
  • How much rain can I collect from my home gutter system?
    You can use this rainwater collection calculator to determine your roofs catchment capability. (Sonoma County has an average annual rainfall of about 39 inches. Enter that number into the appropriate field in the calculator.)
  • What sizes of rain tanks can I use?
    Your typical rain catchment system could range anywhere from stacked 300 gallon totes, to 550 gallon slim line tanks, to much larger tanks up to 5,000 gallons. Anything greater than 5,000 gallons requires a permit.
  • How many plants or trees can my L2L greywater system feed?
    We recommend between 6 and 10 large bushes or trees.
  • How much water does a Laundry-to-Landscape greywater system run to my yard?
    You can expect anywhere from 10-20 gallons per load of laundry depending on the load size. (If you're doing just 2 loads per week, thats between 1,040gal. and 2,080 gal. per year that's going back into your local ecology!)
  • How long does a Laundry-to-Landscape system take to install?
    Generally our team of specialists can install a system in 2-3 days barring any unexpected complications.
  • What types of greywater systems are there?
    The easiest greywater system to install is a laundry-to-landscape (L2L) system. This will be the lowest cost to entry system and provides a great benefit to your surrounding landscape. Other greywater systems include systems that utilize the greywater from showers and sinks. These systems are generally more costly and time consuming to install.
  • What is greywater?
    Greywater is gently used water from your bathroom sinks, showers, tubs, and washing machines.Greywater may contain traces of dirt, food, grease, hair, and certain household cleaning products. While greywater may look “dirty,” it is a safe and even beneficial source of irrigation water in a yard. Keep in mind that if greywater is released into rivers, lakes, or estuaries, its nutrients become pollutants, but to plants, they are valuable fertilizer. Aside from the obvious benefits of saving water (and money on your water bill), reusing your greywater keeps it out of the sewer or septic system, thereby reducing the chance that it will pollute local water bodies. Reusing greywater for irrigation reconnects urban residents and our backyard gardens to the natural water cycle.
  • What types of plants or trees should I direct my L2L greywater to?
    Larger bushes, fruit baring trees, shrubs, etc. are perfect candidates for L2L greywater.
  • Can L2L greywater be used for drip irrigation?
    As laundry greywater is generally filled with sediment and dirt, it would need to be filtered heavily in order to not clog the drip irrigation lines. Instead, we recommend using larger lines that lead to the bases of fruit baring trees, bushes, or shrubs by a long flexible line called Blu-lock.
  • Do I need a permit for these systems?
    You do not need permits for either laundry-to-landscape (L2L) or rain catchment systems with tanks under 5,000 gallons without pumps. Other greywater systems that require construction or rain catchment systems that have pumps will require permits.
  • Why should I do this?
    Wether choosing to do a greywater or rain catchment system, the direct ecological impact is huge. This small, but mighty act puts you in direct relationship with your local water ecology, and can really help against drought.
