Mr. Eddie Taaffe:

While I am no expert in wastewater treatment, some local authorities conducted a pilot for a reed-bed system, where there was no discharge at all from the wastewater. The wastewater went into a reed-bed system of sufficient size and, following evaporation and treatment, there was no discharge into the environment. There are innovative solutions but they cost more and require more maintenance. A reed-bed system may be a solution for certain areas, and it might be the only one that works in the case in question. Perhaps consideration should be given to conducting a pilot of a reed-bed system.
