A new commercial scale dyeing technology for dyeing synthetic fabric, DyeOx, has been implemented in Taiwan that utilises carbon dioxide (C02) instead of water in the dyeing process. The technology uses no water, no auxiliary chemicals and reduced energy when compared to conventional processes. The technology was conceived at DELFT University and commercialized by the [...]
In a search for improved irrigation practices, three farms near Milan, installed a drip irrigation system coupled with soil moisture monitoring as part of the AquaTEK™ programme. This system allows farmers to irrigate only when needed, without stressing the plants by supplying too much or too little water. The system also allows for more precise [...]
The Lake Victoria Environmental Management Project (LVEMP) is a cross border initiative funded by the World Bank designed to rehabilitate some of the major environmental concerns present in the Lake Victoria Basin. One of the pollution hot spots targeted under the program was the Kibos Sugar and Allied Industries factory (KSAI) in Kisumu, Kenya. Under [...]
The government and its regulators require all water companies in England and Wales to plan water resources at least 25 years ahead to ensure secure supplies. This is a twin track approach where the company must consider the cost-effectiveness of demand management measures before they propose resource developments. In 2009 compulsory water metering was identified [...]
Yanacocha implemented a comprehensive water management strategy at the mine releasing 35 000 000m3 of treated effluent per year into the local river. Furthermore, as part of a proposed expansion and in order to address environmental concerns and ongoing disputes over water, it decided to extend its water management programme beyond the mine boundary. In [...]
Weak enforcement of groundwater licencing and effluent treatment standards has led to high rates of water use in the textile mills and discharge of toxic effluents into the surface water bodies. The Water PaCT Bangladesh is a partnership founded to drive the wet processing textile sector in the country towards a more sustainable performance and [...]
Egypt has less than 700 m3 per capita per annum freshwater availability of which 85% is withdrawn for irrigation purposes. The Integrated Irrigation Improvement and Management Project (IIIMP) in the Nile Delta has been implemented to improve water distribution, quantity, quality, equity and timeliness and hence to increase agricultural production and alleviate poverty.
The Arvind textile mill located near Kalol, Ahmedabad District, India uses over 6.5 million m3 of process water per year. Limitations on groundwater extraction coupled with the lack of a nearby location for effluent discharge led to the implementation of a complete water reuse system. The total water available from the local aquifers is approximately [...]
In addition, operational responsibilities were decentralized and the irrigation infrastructure was transferred to local water user associations (WUA); a key requirement for the financing provided by IBRD (World Bank). The locally prioritized improvement plans by the WUAs delivered the rehabilitation of the irrigation system supplying water to 427 100 hectares of farmland. The reduction in [...]
So a plan was launched to increase groundwater recharge through the construction of six recharge structures. Scheduled training programs for local farmers on water efficiency practices were also implemented to reduce withdrawal for agricultural purposes. This is benefiting more than 4 000 farms on a regular basis. In addition, water efficient agricultural practices were showcased [...]
