Also there was an observation of high health risk concerns among respondents; the majority of respondents (67%, n = 60), although not statistically significant (p = 0.750), perceived that it was unsafe to irrigate vegetables (crops) with greywater (Table 3). This perception is legitimate because public health risks of greywater irrigation for edible biomass are widely established (Pinto & Maheshwari 2010; Benami et al. 2016; Cook 2016), especially when greywater is not treated.
