The efficiency of individual units of an effluent treatment plant (ETP) determines the overall performance of the plant and the final effluent quality. In this study an ETP of a composite textile industry in Bangladesh was investigated using this method. Water samples were collected from the main units of the ETP and were analysed for key parameters. The results were used to diagnose problems with the treatment units and to suggest modifications. From this, a simple but robust methodology was developed for evaluating the performance of the different treatment units and the ETP as a whole that could be implemented by ETP managers on a regular basis to improve the performance so that the effluent leaving the factory meets national standards and conforms to the requirements of international buyers. The results showed that poor management, especially chemical dosing, was seriously affecting the ETP's performance and that simple measures could address the problems.

The AgWater Solutions Project, carried out between 2009 and 2012, focused on resolving water issues faced by smallholder farmers. The project examined existing Agricultural Water Management (AWM) solutions, together with factors that influence their adoption and scaling up. The project aimed to identify investment opportunities in AWM that have high potential to improve the incomes and food security of poor farmers. The work was undertaken in the African countries of Burkina Faso, Ethiopia, Ghana, Tanzania and Zambia, and in the Indian States of Madhya Pradesh and West Bengal. This Working Paper series summarizes results and recommendations from the research carried out in each of these countries and states
