Within the water partnership activities between WEC and the water sectors, the seminar titled (Evaluation of the current and potential waste water reuse. A demonstration plot at Sana’a WWTP) was Held on Wednesday 10/2/2016 at the Water and the Environment Center.
In this study, A Demonstration plot was applied inside the yard of the Sana’a wastewater treatment plant (SWWTP) in order to study/mimic and evaluate the current uses of sewage emerging from Sana’a treatment plant as well which sometime discharged from un-treated due to the overloading of the treatment plant. The irrigation is applied with mixing with the Groundwater to study the alleviation of the alternate irrigation to public health and the environment. Two crops namely squash (cucarpite spp.) and Alfalfa (alfalfa spp.) were planted and irrigated using seven water quality treatments levels as follows: Groundwater from a well at the SWWTP yard (GW) – as a control, Treated wastewater effluent from the open channel (WW), Raw wastewater (RWW), Raw ww with alternating GW (RWW+GW), Treated ww with alternating GW (WW+GW), Groundwater with adding needed nutrients using treated ww (GW_WWF) Groundwater with adding needed nutrients using raw ww (GW+RWWF). the total production of Alfalfa crop which was harvested only once at the end of the period. At the same time, the total production of the Squash crops for total three harvesting times. The Results of soil analysis before planting showed significant increase in organic matter after applying the wastewater with different treatments which was reflected into soil fertility, while the rest of the analysis didn’t show significant difference may be due to the available nutrients and pathogens in the soil before planting. It is concluded that irrigating with wastewater either raw or treated is beneficial, while on the other hand it is advised to raise the plant from the soil so that it does not get in contact with the pathogens in the wastewater. Regarding to the contaminated surface of the crops, it should be noted that it should be washed with chlorine to remove the FC adsorbed before it is marketed.
