81309069-River water quality monitoring and database management system establishment

This tender is part of the project "Strengthening Institutions for Climate Change Adapted Water Resources Management in Dhaka", which is commissioned by the German Federal Ministry for Economic Cooperation and Development (BMZ). The project supports its partners in improving the institutional and technical foundations to ensure water quality in the Meghna River. Dhaka, the capital of Bangladesh, home to approximately 15 million inhabitants, primarily relies on groundwater for its safe drinking water supply. However, this vital resource is under threat due to over-extraction, and the effects of climate change. To reduce the stress on groundwater, conjunctive use of both ground and surface water for water supply of Dhaka City should be practiced. However, the rivers (Buriganga, Shitalakshya, Dhaleshwari, Balu, Turag, etc.) surrounding Dhaka suffer from severe water pollution making them unsuitable for use. The main contributors to this pollution include rapid urbanization, unplanned development along riverbank including industries without/nonfunctional effluent treatment plants (ETP) and settlements without sewage treatment facilities, and insufficient capacity of different stakeholders to monitor water quality and enforce environmental regulations. To ensure long-term, sustainable safe drinking water supply for Dhaka"s residents, the Government of Bangladesh plans to source water from the Meghna River. As of now the water quality of Meghna River is relatively good and the quality must be retained in future not to overstress the treatment plant. The SAIDABAD Phase III treatment plant is set to abstract water from the River Meghna. The intake point is strategically located at Haria, an area characterized by a diverse range of industrial activities. Significant water vehicle traffic is observed near the intake, primarily due to the substantial industrial development in the surrounding region. Moreover, there are a lot of canals which are draining to the river in the proximity of the intake location. Dhaka Water Supply and Sewerage Authority (DWASA) has developed a draft water quality monitoring plan for River Meghna encircling the intake recognizing the significant role that Meghna River will play in meeting the water needs of Dhaka City in the future. To support its partners in improving the institutional and technical foundations to ensure water quality in the Meghna River, the project implements the following activities:? Establishing a coordination process to align measures to protect the quality of water in the Meghna River in line with the Meghna River master plan.? Setting up an integrated water quality monitoring system to improve the institutional capabilities required to maintain suitable water quality and ensure safe water supply.? Enhancing the capacities of large-scale industries and SMEs to minimise water pollution.? The contractor should contribute to the second activity "Setting up an integrated water quality monitoring system to improve the institutional capabilities required to maintain suitable water quality and ensure safe water supply" and its respective indicator "Monitoring data used by 3 key institutions for 20 parameters at the water abstraction point is available to the public." At the moment, neither monitoring data are collected on a regular basis nor for all parameters. The results are not available to the public. Draft concepts for the river water monitoring and database management system are already under development (commissioned with a separate tender) based on scientific knowledge and worldwide standard practices. The consulting package subject to this tender has to build a monitoring and database management system based on the draft concepts. The river water quality monitoring and database management system, which is to be designed by the contractor has to comply with Laws and Regulations of the People's Republic of Bangladesh; WHO Water Safety Plan concept "Managing drinking-water quality from catchment to consumer" and the Directive 2000/60/EC of the European Parliament and of the Council of 23 October 2000 establishing a framework for Community action in the field of water policy "EU COUNCIL DIRECTIVE 98/83/EC of 3 November 1998 on the quality of water intended for human consumption". To set up a monitoring system of river water quality and a database, the contractor shall, inter alia, carry out the following activities in close coordination with GIZ and its partners in Bangladesh:? Finalizing the selection of locations for establishing the monitoring stations; Finalizing the water quality parameters to be sampled in the monitoring stations; Defining/ Identifying sensors used in the monitoring stations; Designing a protection and safety concept and contingency plan; Supporting GIZ in procuring river quality monitoring equipment; Installing the monitoring system; Drafting a maintenance plan; Providing recommendations for lab facilities from DWASA, Department of Environment (DoE) or other organization"s labs, responsible for Meghna River water quality monitoring; Implementing an online/offline data collection, storing and translation process; Establishing a water quality visualization dashboard and warning system; Ensuring data protection; Training for DoE and DWASA staff; Piloting and revising; Drafting an exit plan or handover plan.
