Frequently Asked Questions
Greywater systems significantly reduce your water bill and reliance on municipal water, which is especially important during droughts. They also lower your environmental footprint by conserving a precious resource and reducing the energy needed to treat and transport water. Plus, recycled greywater can be used for irrigation, keeping your landscape healthy.
Greywater systems collect wastewater from showers, sinks, and laundry machines, diverting it from the sewer line. The water is then filtered and disinfected to remove contaminants. This treated water can then be used for subsurface irrigation, toilet flushing, or other non-potable purposes, reducing the demand for freshwater resources.
Yes, greywater systems are legal in Los Angeles and California, but they must comply with state and local regulations. These regulations cover system design, permitting, and water quality standards to ensure public health and environmental safety. Custom Green Construction Inc. can handle all permitting and ensure your system meets all requirements.
