pnumia, I would check that the dishwasher detergent does not contain additives to 'soften' the water or similar 'benefit'. I'd also test the temperature of the discharge.

Hi pnumia,

Your local Agricultural Extension Service could give you information about the local regulations for what you want to do. The reason is that untreated excess water (Runoff) not going to your sewer treatment plant will affect your local water tributaries or local ground water. The Ag Office could give you ideas on what to do or give the results of a water sample you give them. Another issue is how much water will you produce and whether you can match the needs of the plants you want to nourish. You might need to flip the system back and forth from sewer to garden as the weather changes the needs of your plants or in between planting cycles. These are thoughts in addition to the good ideas in the previous post. Another thought is; do you have a electric garbage disposal in your sink? Probably good compost material. Let us know what you end up doing. GL and Thanks. Aloha.
