Contribution to the Study of the Problem of the Management of the Network of Distribution of Water Processed by Plants Tshopo and Burned in the Kisangani Region (DR Congo)

This study is to assess the possibility of alteration of the quality of treated water output of the Tshopo plants through the faucets of users taking into account the age of low pressure (LP) and high pressure (HP) network and due to hydraulic residence time population growth estimated at 294, 37 percent, the lack of sanitation facilities and excessive so no recycled human waste production as weather conditions. The age of the LP, especially after very heavy frequent rains year-round in the Equatorial area, affect the quality of treated water between the output of factories and the taps of the users. In chemical terms, 2 samples processed on 170 gave color and turbidity slightly higher than national standards with peak maxima days of intense rainfall. On a microbiological level, fecal streptococci (SF) appear to be resistant to disinfection than fecal coliform (FC). Medians of most probable number (MPN) per 100 ml of the SF went from 28 to 30 falling to 7 then back to 19 to the BP (old network) and from 28 to 14 in 17 at HP (nine network). Those of the FC zero out of factories (0P2), on a few taps of the BP (3P3, 4P7, 4P11 and 4 P12) and all the taps in the HP. The rest of the taps, following a heavy rain or a healthy environment, gave values greater than the standard DR Congo (0/100 ml). Hence the need to establish good human waste management and good environmental sanitation policy and also adaptation, days of intense rainfall, the treatment changes in various parameters of first aid in order to improve the quality of water to produce, according to the World Health Organization (WHO) guidelines and standards, DR Congo.
