Integrated tidal wastewater treatment system and method

A method for treating wastewater comprising the steps of:

• subjecting wastewater to be treated to a first substantially aerobic environment for a first time period;
• transporting water from the first aerobic environment to a surface of a first substantially aerobic/anoxic environment containing plants having roots for a second time period;
• transporting water emerging from beneath the plant roots of the first aerobic/anoxic environment to a second substantially aerobic environment for a third time period;
• transporting water from the second aerobic environment to a surface of a second substantially aerobic/anoxic environment containing plants having roots for a fourth time period;
• and
• recycling at least a portion of the water emerging from beneath the plant roots of the second aerobic/anoxic environment to the first substantially aerobic environment.

A method of treating wastewater comprising the steps of:

• transporting wastewater to be treated to the first substantially aerobic lagoon containing aquatic plants;
• transporting water from the first lagoon after a first time period of retention within the first lagoon to a first marsh cell containing particulate media and plants growing on a top surface of the media, so that roots of the plants can grow to extend into the media;
• transporting water from the first marsh cell to a second substantially aerobic second lagoon;
• and
• transporting water from the second lagoon after a second time period of retention within the second lagoon to a second marsh cell containing particulate media and plants growing on a top surface of the media, so that roots of the plants can grow to extend into the media.
