There are two main rules to follow to protect the environment.

• Send nothing toxic down the drain.
• Do not allow greywater to enter a fresh water source, like a creek, stream, or river, or high groundwater table. Biodegradable material will compost on the land, but will contaminate a creek. Nutrients will fertilize plants on land, but will cause algae to grow and rob water of oxygen, harming aquatic organisms.
• Use biodegradable products that are salt and born free (which harm plants and the soil)
