Regular maintenance of a greywater system typically involves cleaning and replacing filters and making sure the system continues to function as designed. Below are a list of greywater do’s and don'ts courtesy of the Water Conservation Alliance of Southern Arizona www.watercasa.org.
- Your irrigation system should be operated to efficiently provide sufficient water to your plants while minimizing loss from deep percolation beyond the root zone.
- Filter your greywater with something as simple as a stocking to trap hair and lint. Clean and/or replace this filter regularly.
- Regularly check your greywater system to be sure it is functioning properly.
- Frequently check your plants that are greywater irrigated for signs of over watering or stress from high organic content in the water.
- Check for information about ingredients in laundry products that may affect the plants you are irrigating.
- Divert your greywater to your sewer or septic system when laundering diapers or dying clothes.
- Don't drink your greywater.
- Don't use water from the laundering of diapers because the bacterial contamination is too high and is a health risk.
- Don't use water that contains hazardous chemicals such as those used for cleaning car parts, washing of greasy or oily rags, disposal of solutions from home photo labs or similar hobby activities.
- Don't allow your greywater to pond beyond what is necessary to effectively irrigate your plants. Standing water increases health risks and provides breeding opportunities for mosquitoes.
- Don't use greywater to irrigate food crops intended for human consumption.
- Don't reuse your greywater if any family member has an infectious disease such as diarrhea, hepatitis or internal parasites.
