Water and Wastewater Quality Monitoring Guidelines for Water Utilities.

These Guidelines provide guidance to Water Utilities to develop their own water quality monitoring programs for drinking water supply and wastewater effluent discharges. The Water Utilities are Water Supply and Sanitation Authorities, Dar es Salaam Water and Sewerage Corporation (DAWASCO) and the Dar es Salaam Water and Sewerage Authority (DAWASA). There are two types of water and wastewater quality monitoring, namely Check Monitoring and Audit Monitoring. Check monitoring regularly provides information as to whether the water quality complies with the relevant parametric values laid down in the latest relevant Tanzania Standard. Audit monitoring provides information necessary to determine whether or not all the parametric values specified in the latest relevant Tanzania Standard are complied with. The minimum requirements for monitoring the quality of water and wastewater services to consumers include i. to monitor the minimum required number of samples and tests on quality of water supplies, ii. to monitor the minimum required number of samples and tests on quality of wastewater effluents, iii. to collect data, analyse and check compliance with set standards, and iv. to ensure publication of test results.
