Fecal Coliform data was erroneous for this rate due to an error in the incubation time of the samples, therefore their results have been excluded from the above table. From visual inspection of both plots, the experimental plot had a more dense and greener stand of grass with relatively no weeds. The control plot contained large yellow patches of dry grass and was overrun with weeds. The weeds in the control plot benefited from the irrigation pipe being much deeper than the root zone of the grass, allowing the weeds long root system to dominate the water supply. In the experimental tank the grass was so thick that there was little room for competition, leaving the plot virtually weed free.
More study is needed however, in order to monitor the system at different loading rates.
Furthermore, study must be continued through the months when the grass is dormant in order to determine this effect on nutrient uptake and the corresponding quality of the effluent. The use of natural systems for municipal wastewater management and treatment has become a growing interest. These methods help promote the maximum recycling and reuse of wastewaters, increasing efficiency while decreasing costs. Outside the reach of municipal treatment plants, potential development is hindered until an economical method of wastewater treatment is made available. By watering slowly but regularly, the pollutants have time to accumulate in the root structures of the plants.
