Greywater is water from showers, bath tubs, washing machines, and bathroom sinks. Using greywater is an innovative way to reduce potable water use and flows to the sewer system. It provides for an efficient means to irrigate plants in your landscape, and provides natural groundwater recharge.
There are three types of greywater systems – Laundry-to-Landscape (L2L), Simple, and Complex greywater systems.
Laundry to Landscape
PWP offers an L2L Greywater Program due to their simplicity, affordability, and easy maintenance. L2L systems are the only type of greywater system that does not need a permit to be installed.
Watch this video to view testimonials from PWP customers who have successfully installed an L2L system in their home:
Simple Greywater Systems
Simple greywater systems exceed a Laundry-to-Landscape greywater system and have a discharge capacity of 250 gallons per day or less. Simple greywater systems collect water from bathtubs, showers, and bathroom washbasins for irrigation purposes. Simple greywater systems do not include wastewater from toilets, kitchen sinks or dishwashers. Simple greywater systems require a permit, design and inspection by the City of Pasadena Planning and Community Development Department, because construction and installation of simple greywater systems require cutting of the existing plumbing piping. PWP designed a streamlined permit process and a rebate for permit fees to ease the participation in Simple Greywater Program.
