    Urban wastewater utilization for economic activities in Dodoma urban district, Tanzania
    (International Journal of Research in Chemistry and Environment (IJRCE), 2015) Mamboya, Sarah F.; Tenge, Albino J.; Masanyiwa, Zacharia S.
    In the semi-arid areas of Tanzania that experience frequent periods of drought, wastewater is a critical resource for landed and landless households. This wastewater, which is generated daily by a rapidly growing population, and which flows into the ground, supports a variety of livelihood activities that require water. This study was conducted among 215 randomly and purposively sampled respondents to assess the use of wastewater for economic activities for improving livelihood in Dodoma Municipality which is one semi-arid areas in Tanzania. Specifically, the study intended to (i) identify the economic activities practised, (ii) determine the main economic activities that utilize wastewater and, (iii) find out the extent of wastewater utilization for economic activities in the study area. Primary data were collected through a survey among wastewater users and semi-structured interviews with key informants. Secondary data were collected through documentary review of different documents obtained from the relevant offices and officials. Descriptive statistics including cross tabulation and frequency distributions were analysed. The findings show that the major economic activities that utilize wastewater are farming (48%), livestock keeping (41%), brick- making (32%) and fishing (9%). The majority of respondents used wastewater resource for gardening, mainly tomatoes (26 %), followed by green vegetables (18%), okra (18%) and cowpeas (17%). With regard to livestock keeping, the majority of respondents used wastewater for rearing cattle (42%), goats (32%) and pigs (10%). Despite the existing economic activities that utilize wastewater, wastewater is generally underutilized in the study area. Therefore, policy makers and other stakeholders should ensure full utilization of wastewater potentials including, construction of livestock watering areas, fishing ponds, dips and irrigation structures.

    Wireless sensor networks for water quality monitoring and control within lake victoria basin: prototype development
    (Scientific Research Publishing Inc., 2014) Faustine, Anthony; Mvuma, Aloys N.; Mongi, Hector J.; Gabriel, Maria C.; Tenge, Albino J.; Kucel, Samuel B.
    The need for effective and efficient monitoring, evaluation and control of water quality in Lake Victoria Basin (LVB) has become more demanding in this era of urbanization, population growth and climate change and variability. Traditional methods that rely on collecting water samples, testing and analyses in water laboratories are not only costly but also lack capability for real-time data capture, analyses and fast dissemination of information to relevant stakeholders for making timely and informed decisions. In this paper, a Water Sensor Network (WSN) system prototype developed for water quality monitoring in LVB is presented. The development was preceded by evaluation of prevailing environment including availability of cellular network coverage at the site of operation. The system consists of an Arduino microcontroller, water quality sensors, and a wireless network connection module. It detects water temperature, dissolved oxygen, pH, and electrical conductivity in real-time and disseminates the information in graphical and tabular formats to relevant stakeholders through a web-based portal and mobile phone platforms. The experimental results show that the system has great prospect and can be used to operate in real world environment for optimum control and protection of water resources by providing key actors with relevant and timely information to facilitate quick action taking.
