Assessment of greywater management in unplanned settlements in Kinondoni municipality

Greywater management is an important aspect in protection of public health, environment and as well as resource conservation. In Tanzania Studies have been done on GYW but this study went further to analyse the institutional arrangement for GYW management. The aim of this study was to assess the greywater management practices in unplanned settlement of Kinondoni municipality. Data were collected through field survey by using semi-structured questionnaires, observation and interview. Sampling and laboratory analysis was done to determine the quality of the GYW in accordance with the standard methods. The survey covered a total of 110 households; also 8 staffs from the municipality were involved. Results revealed that there was poor GYW management practice in the study area and 51.4% of the households had a perception that GYW is dirty water that has no use. Also the idea of treated GYW reuse was massively rejected and majority of the households had a limited awareness and knowledge on the best GYW management practices. It was found that GYW generated accounts for about 70% of the total water consumption at households contributed by bathing 46%, laundry 14% and 10% by kitchen. The GYW quality data showed that treatment is necessary prior to discharge or reuse. Moreover it was found that the existing situation of poor GYW management is rooted at the inadequacy existing in the institutional structure. This study recommends on awareness rising, source separation of GYW from black water, treatment and reuse as the best GYW management practice.
