Q) Who can have one of our simple systems installed?

A) Single home owners, and duplex owners.  Apartments and Condominiums require larger systems, and have a lengthy permit process.

Q) What type of home is appropriate?

A) Homes where the washing machine is against and outside wall are ideal, as we will drill a hole and then run the line underground.  If the home has a crawlspace we can run the line under the house.  Homes on slab foundations are more difficult unless the washing machine is near an outside wall. Second story laundry rooms can also be challenging, though not impossible.

Q) What are the costs?

A) $600 (DIY) to $100,000 depending on the system.  With the typical laundry to landscape option being the least at $600 to $2,500 on average. The L2L system is the easiest and lowest cost option for a homeowner to set up and can make the most immediate impact on the drought.  A Standard system through 2G is $1600 including all parts and labor.

Q) Can I water my grass with grey water?
A)No.  Grey water has to be released drip style, underground.  So rarely for grass unless you have a more sophisticated system!  Though you may save enough elsewhere to continue having a lawn…

Q) How do we start the process?

A) Call or email us for a brief consultation.  If appropriate we will then ask for measurements of distances, have you check access from laundry to the outside, and possibly send over some photo’s.  We’ll then send you a quote, and if all looks good we’ll lock in your installation date.

Q) Is it safe?

A) Yes there has never been a reported safety issue with grey water.

Q) For my washing machine what products are safe?

A) When cycling water to your landscape you will need to use more plant friendly detergents.  When you want to use bleach or traditional detergents you can just switch the valve back to the sewer setting.  In our home we use 90% grey water safe, and 10% traditional for whites, or bleach.  Here’s a list of products you can find that will work well for grey water.  Ecos and Vaska can be found in many retail stores.  Oasis Laundry Detergent (liquid), ECOS liquid detergent, Vaska, and Dr. Bronners liquid soap. Vaska also makes a commercial laundry detergent that is compatible with commercial washing machines.

Q) How is the water filtered?

A) Around each distribution point on your landscape we will built a mulch basin.  The grey water is filtered there prior to reaching your plants.

Q) Is it legal?

A) Yes, Per California code and  Under the new 2009 California grey water code, washing machine systems that do not alter the existing plumbing do not require a permit as long as the installer follows these guidelines.

System must:

1) Have an easy way to direct flow back to the sewer/septic (3 way valve).  The valve must be labeled.

2) Send the water to irrigate landscape plants.

3) Keep the water on the same property it is produced.

4) Have a maintenance manual

5) Discharge grey water under a 2 inch cover of mulch, plastic shield, or stones.

System must not:

1) Contain diaper water.

2) Contain hazardous chemicals (such as from a home photo lab).

3) Have pooling grey water or runoff.

4) Make grey water accessible to people or pets (such as in an open tub).

5) Include a pump (except the washing machine pump).

6) Connect to the potable water supply.

7) Affect other parts of the building, such as the electrical or structural components.

Q) What areas do you cover?

A) Second Generation maintains two offices servicing Los Angeles and Orange County.  With mileage factored in Riverside, San Diego and San Bernardino Counties can be serviced.

Q) Who invented Grey water?

A) Art Ludwig of Oasis Designs is credited as being the founder of Greywater in North America.
