Water management at a textile industry : a case study in LesothoMasupha, Tholoana Marcellina 22 April 2008 (has links)
Textile industries use large amounts of water in their production processes, with subsequent generation of large quantities of wastewater. With ineffective and/or inefficient water management protocols in place, these industries can have a large negative impact on the environment. In order to assist in the development/setting of suitable actions to negate environmental impacts from textile industries, it is essential that some form of water management, and more particularly a water balance, be in place. This dissertation investigated the current practices at a textile industry in Lesotho, CGM Industrial, as a case study with the ultimate objective to assess and present suitable water management actions to negate the company’s negative impact on the environment. An active water balance was compiled for one of the company’s factories, CGM 1, and illustrated that large volumes of water (up to 0,9 Ml/day) are discharged to the natural water course, often untreated. The water balance specifically addresses water usage for the four wet processing combinations present at CGM 1, and representative of the textile industry as a whole, namely stone washing/washing, stone washing/bleaching, stone washing/dyeing and stone washing/bleaching/dyeing operations. Based on the water balance results and general assessment of operating practices in place at CGM 1, suitable water management actions were recommended for reducing wastewater volumes, substitution and reduction of process chemicals, and investigating process modifications. / Dissertation (MSc (Environmental Technology))--University of Pretoria, 2008. / Chemical Engineering / unrestricted

Evaluating water conservation and water demand management in an industrialised city: a case study of the City of uMhlathuze in Richards BayMthethwa, Nkosinathi I January 2018 (has links)
The objective of this study was to evaluate water conservation and water demand management in an industrialised City of uMhlathuze in Richards Bay. The City of uMhlathuze Local Municipality is the third-largest municipality in KwaZulu Natal (KZN) and is strategically placed to continue attracting investment as an aspirant metropolis due to the newly established Industrial Development Zone (IDZ) and the country's largest deep-water port. As an industrialised city, uMhlathuze's demand for water is already increasing and with the establishment of the IDZ, it is expected that water demand will escalate even further once the IDZ is fully operational. In line with the research question, this study has, therefore, sought to understand whether the industrialised City of uMhlathuze has developed and effectively implemented a water conservation and water demand management strategy and interventions in order to sustain water supply in anticipation of growing demand due to industrialisation and population growth. This objective was achieved by evaluating the city's current interventions and measures using a range of water conservation and water demand management solutions and guidelines. During this study, it was evident that the greatest threat facing South Africa's ambitious future economic growth, poverty alleviation and government's transformation agenda was the inefficient and unbalanced use of available and limited water resources. Thus, in order to avoid this imminent threat, the country as a whole must continuously reduce water consumption and demand from various sectors. This goal can be achieved through sustainable and improved water conservation and water demand management interventions. The study found that, in recent years, the issue of water scarcity had escalated in KZN. The province was in the grip of a drought, which was taking its toll on water supply in various municipalities around the province. The sparse rainfall in most parts of the province had caused the levels of rivers and dams to decrease to a point of crisis. Consequently, the KZN Provincial Government declared the province a disaster area in 2015. During the study, there was very little improvement as the City of uMhlathuze was still subjected to level 4 water restrictions. Evidently, the drought was intensifying the water problem in a municipality already grappling with poor and inadequate water infrastructure. A review of international and local literature was undertaken to theoretically position the objective of the research. An evaluation of the City of uMhlathuze water conservation and water demand management strategy and interventions was conducted using a questionnaire completed by city officials and part of the study included documentation review. This study investigated key elements of water conservation and demand management as well as interventions that were pertinent to achieving the desired outcome of efficient use of water. Respondents were required to answer questions focusing on several water conservation and water demand management related approaches and solutions. During the study, it was identified that there were inconsistencies in the implementation of water conservation and water demand management interventions even though the City of uMhlathuze had already taken the important step of developing a water conservation and water demand management strategy. It was recognised, however, that water conservation and water demand management remained relatively new for most municipalities. Consequently, it would take time for municipalities, together with communities, to implement effective interventions. The focus needs to be on the establishment of a combined team of staff and stakeholders, set up to finding solutions and interventions designed to maximise the most sustainable and efficient use of water. The conclusions drawn from this study and proposed recommendations indicated that wastewater reuse; pipe replacement; water pressure management; rainwater and stormwater harvesting; water sensitive urban design; leak detection and repair; joint planning and research team with the Industrial Development Zone; groundwater and aquifer recharge; stakeholder engagement, education and citizen awareness are feasible options for the City of uMhlathuze to consider in relation to water conservation and water demand management. These solutions should constitute the foundation of a revised and updated water conservation and water demand management strategy to be implemented incrementally with broad-based participation.

An investigation into how value is created through water sensitive urban designMallett, Gregory David January 2017 (has links)
A key challenge facing developing countries is the rapid increases in urbanisation and the effect this has on their water systems. Water sensitive urban design (WSUD) is a process that considers the entire water system with the aim of achieving a water sensitive city (WSC). However, little is known about how value can be created through WSUD in terms of the sustainability of urban precincts in South Africa. The researcher therefore considered the well-established literature highlighting the relationship between WSUD and sustainable urban development. To understand the value derived from these concepts, two case studies were assessed, namely the Victoria & Alfred Waterfront (V&A Waterfront) and Century City. However, it should be highlighted that due to the uniqueness of these cases, no generalisations from the findings can be generated. The methodology implemented for the case studies was social constructivist in nature and to satisfy the research objectives, semi-structured interviews were conducted, documentary material was gathered, and photographic evidence was collected. Moreover, a diverse collection of data was assessed, which was extracted through various methods of data collection, thereby resulting in an in-depth understanding of the case studies. This research concludes there is a relationship between WSUD, sustainable urban development and value. It further argues that the underlying principles of facilities management (FM) and more specifically urban FM provide a managerial framework that can connect these concepts to achieve sustainability for urban precincts. Furthermore, the study uncovered the need for value capture mechanisms as a form of infrastructure financing and value creation for urban precincts. However, it was established that neither case study make use of such mechanisms, so future research is required in this regard.

How spatial planning can enable pathways to the implementation of sustainable urban drainage systems in the city bowl, Cape TownHarvey, Catherine January 2018 (has links)
The dramatic global trend of population growth has led to a rapid urbanisation, resulting in unprecedented land cover change. The incarnation of accompanying developed has typified impermeable surfaces. These surfaces have disconnected the stormwater component of the natural hydrological cycle, disregarding it as a nuisance and designing it to be rapidly removed from urban areas. Utilising Sustainable Urban Drainage Systems (SUDS) offers opportunities in urban areas to recycle the water and challenge the perception that stormwater is a nuisance and of no value. The current context of drought experienced by Cape Town has highlighted the need for less reliance on surface water resources; implementing SUDS could be a way of reconnecting the hydrological urban water cycle. It could also help to repair the human disconnect from nature that is prevalent in urban areas. The research question explored the role of spatial planning in enabling the implementation of SUDS in the City Bowl, Cape Town. While conceptual and technical frameworks have been developed for SUDS in South Africa, at present there is no spatial guide as to how these interventions could be realised in a specific context and area. This research utilise s the tools of spatial planning to re-imagine the City Bowl in relation to water. The case study methods used, enabling a detailed understanding of the site. This was complemented by interviews with various planning professionals in order to understand the current role spatial planning plays in terms of implementing SUDS. The research suggest is that whilst SUDS has many constraints, the opportunities that they provide for improving water quality and quantity, and surrounding amenities, suggests that this is one which has to be embraced if the City Bowl is going to respond innovatively and sustainably to the drought. It also highlights the need to improve coordination across different spheres and departments of governance, and emphasises the need to value local community knowledge. A prevalent silo approach to complex problems is no longer acceptable. The implications of the research are that implementing SUDS in the City Bowl requires planners to embrace a water literacy approach to spatial plans, and in doing so, return the focus to water

Water Management in Jordan and its Impact on Water ScarcityAl Omari, Hanan 03 March 2020 (has links)
Jordan is among the poorest countries in the world with respect to water resources. Water scarcity in Jordan is an alarming problem that can jeopardize the economy and the stability of the country. It is a multidimensional problem caused by many factors such as the fluctuation of annual precipitation rates, the rapid change in population caused by the refugee influx from neighbouring countries, and the economic situation of the country. The water scarcity problem is aggravated by limitations in water management. This research investigated the shortcomings of water management that contribute to water scarcity. It involves a literature review, a survey questionnaire and interviews. These methods aim to assess the current challenges that prompt water scarcity, understand the water management shortcomings and their causes, identify the existing government solutions for water scarcity, and propose a sustainable solution for this problem.
The research finds that water management in Jordan has several shortcomings such as the lack of monitoring and controlling water resources and preventing illegal drilling, the incapability of the government to reduce the non-revenue water as a result of aged water network and water theft, and illegal practices of the agricultural and industrial sectors. This research proposed a solution that aim to mitigate water scarcity in Jordan by enhancing several management practices. Moreover, the proposed solution calls for efficient managerial practices to be adopted by decision makers and the public. I argue that the proposed solutions are sustainable and cheaper than the existing government solutions that rely on searching for new water resources rather than improving water management.

Developing capacity for agricultural water management: Current practice and future directionsFranks, Tom R., Garces-Restrepo, C., Putuhena, F. January 2008 (has links)
Yes / This paper defines concepts of capacity and capacity development for agricultural water management, and particularly the contributions made by ICID in this area in the recent past. Working from a theoretical framework of overlapping domains of capacity development ¿ the enabling environment, the organisational and the individual domains, with knowledge management as a cross-cutting theme ¿ the paper reviews previous work in the field and then summarises a range of case studies from the sector which illuminate key aspects of these different domains.
The paper notes the need to accommodate a rapidly-changing context for agricultural water management to take account of the increasing demand for water resources in all sectors, and the consequent requirement for support of new approaches to capacity development. These new approaches emphasise the growing importance of authentic knowledge, internally-generated learning and self-development, whether at the level of the organisation or the individual. The paper also recognises the need for continuing and long-term support of capacity development, particularly in processes of organisational and institutional change, where there is no single set of guidelines or practices which will fit every situation. Specific directions for future work are suggested, including increased attention to monitoring and evaluation of capacity development, and closer links to emerging work on water governance. / None

Implementation Impediments to Institutionalising the Practice of Sustainable Urban Water ManagementBrown, R.R., Sharp, Liz, Ashley, R.M. January 2005 (has links)
No / It is now well accepted that there are significant challenges to realizing the wide-spread and self-sustaining implementation of sustainable urban water management. It is argued that these challenges are entrenched within the broader socio-political framework, yet often unsuccessfully addressed within the more narrow scope of improving technical knowledge and design capacity. This hypothesis is investigated through a comparative analysis of three independent research projects investigating different dimensions of the water cycle including stormwater management in Australia, and sanitary waste management and implementation of innovative technologies in the UK. The analysis reveals significant and common socio-political impediments to improved practice. It was evident that the administrative regime, including implementing professionals and institutions, appears to be largely driven by an implicit expectation that there is a technical solution to solve water management issues. This is in contrast to addressing the issues through broader strategies such as political leadership, institutional reform and social change. It is recognised that this technocratic culture is inadvertently underpinned by the need to demonstrate implementation success within short-term political cycles that conflict with both urban renewal and ecological cycles. Addressing this dilemma demands dedicated socio-technical research programs to enable the much needed shift towards a more sustainable regime.
