Opportunities and barriers to sustainability innovation adoption in a UK water and sewerage company

Tanner, Aaron January 2011 (has links)
Over the last twenty years, the concepts of sustainability and sustainable development have assumed political importance around the world, and have been largely embraced by governments and prominent international institutions. These concepts have been a means of tackling the challenges of population growth and environmental change. For the UK water sector, these concepts now represent a multitude of challenges. The confluence of climate change and population growth is reducing access to, and the availability of, water resources. The financial costs of inputs such as energy, chemicals, materials and cost of process by-products such as greenhouse gases, carbon, and waste services continue to rise. Government regulators are demanding an improvement in the quality of services, increasingly stringent conditions for emissions to water, air or land, catchment-specific management of the water environment, and the adoption of longterm planning horizons. The UK government has expectations that the water sector will play a role in the delivery of its targets for reducing energy consumption and carbon emissions. Society demands that WaSCs engage in high-level stakeholder consultations and employ long-term visions to guide their decision-making. Finally, WaSCs are increasingly expected to demonstrate and respond to local and global concerns (under the rubric of corporate responsibility) to further justify their value to society. Cont/d.

Positioning Umgeni Water for the 21st century.

Hadebe, Adolph Slindokuhle. January 2004 (has links)
Umgeni Water was established through Government Notice No. 114 on 14 June 1974. The establishment was facilitated via the legislation operating at that time, namely the Water Act (Act No. 54 of 1956). The organization has grown to be the largest water utility in KwaZulu-Natal and the second largest in South Africa operating in an area of 27 000 square kilometres. Umgeni Water has now expanded its capabilities to cover the full water management cycle and has geared itself up to offer source to sea and source to tap solutions. All the water utilities in South Africa were operating as monopolies because the Water Act (Act No. 54 of 1956) used a system of assigning areas within which the water utilities were to operate. This means that firstly the water utilities were confined to a specific area, and by default meant that these water utilities had a monopoly in that area because the legislation did not permit other service providers. The situation changed in the late nineties when the water sector underwent major legislative and administrative transformation. A number of laws were promulgated including the New National Water Act (Act No. 36 of 1998), the Water Services Act (Act No. 107 of 1997) and a plethora of municipal legislation. The major difference in the "new era" was the introduction and promotion of competition as a means to improve service delivery and enhance benefits accrued by the customers. For the first time in the history of the water sector, water utilities had to compete with other service providers and prove that they can discharge duties and activities better and more efficiently than anybody else. The municipal legislation also empowered and mandated municipalities to be the official authority and provider of water services to the people within their areas of jurisdiction, hence the term Water Services Authorities. If the Water Services Authority lacked capacity, it could choose a service provider that would meet the need. Against this backdrop, water utilities have had to find ways of generating income to survive and this meant that the water utilities had to somehow become relevant in the new dispensation. This included strategies like customer management, increasing operational efficiencies, building capacity of staff through training and development programmes and commercialisation of certain activities. In other words, the water utilities realised that they had to do something, one such thing that was done by Umgeni Water was to position itself so that it becomes a service provider of choice to the Water Services Authorities. In its effort to sustain itself, Umgeni Water cast its eyes beyond the promulgated operational area to the whole of the developing world. In its strategic session that set the tone for 2001 to 2005, the organization envisioned itself being the No.l utility in the developing world. Before being No.l utility in the developing world, Umgeni Water needed to achieve that status in its operational area and South Africa. To be able achieve this position, Umgeni Water needed to know the perceptions being held by the customers in its operational area. This research was undertaken to establish the position that Umgeni Water currently holds in the minds of the customers. This information will assist and inform the future position that Umgeni Water will need to adopt to ensure that its vision is attained. The sample consisted of all Water Services Authorities within the promulgated operational area of Umgeni Water, namely Ugu District Municipality, Sisonke District Municipality, uMgungundlovu District Municipality, Ilembe District Municipality, uMsunduzi Municipality and eThekwini Municipality. The Water Services Authorities seem to be in agreement and appreciative of the fact that Umgeni Water's service provision has improved over the years and 91% of the customers asserted that the main product of the organization, water, met their requirements. This improvement influenced an overwhelming majority (73%) of the Water Services Authorities to proclaim that Umgeni Water was their preferred service provider. These perceptions were fuelled by a number of reasons including the fact that the Water Services Authorities believed that Umgeni Water has the necessary experience, expertise, capabilities and track record to speak authoritatively on integrated water resource management. The Water Services Authorities also believed that the organization is contributing constructively towards the realisation of their developmental mandate and attainment of the water and sanitation goals set by the South African Government through The Strategic Framework for Water Services and achievement of targets set during the World Summit on Sustainable Development in Johannesburg. The Water Services Authorities also identified Umgeni Water's strengths to lie in the fields of water quality management, water quality monitoring, water treatment and laboratory services. This information is crucial because it validates Umgeni Water's position and vindicates the establishment of the organization by the government, whose primary activity was to provide sustainable and high quality water services. There were however customers who felt that Umgeni Water is arrogant, supercilious and untrustworthy. These strong statements were informed by the business dealings spanning a period of 17 years. The only reason that makes these Water Services Authorities continue to use Umgeni Water even under these circumstances is because of the geographical location of the company and its strong financial muscle. The final conclusion drawn is that Umgeni Water is well positioned in the minds of the customers, and is supplying vital services that are perceived by the Water Services Authorities to be adding value to the businesses that they are involved in. In order for Umgeni Water's position to be sustained and cemented in the minds of the customers, immediate attention should paid to critical issues such as ensuring that the intended position of being the service provider of choice is both meaningful and believable by all customers. Umgeni Water should align its value systems, core beliefs and cultures with those of the Water Services Authorities to enhance the possibilities of building long-term relationships. The organisation should also ensure that its Communication Strategy communicates the intended position as well steps to be undertaken to reach that position. It is also important that customers input into this strategy. Umgeni Water should also gather more information on the customers' businesses to enable them to increase the value adding activities and thus leverage value for customers. Another important recommendation is for Umgeni Water to revisit its pricing strategy because of the perception that the products and services are highly priced. The organization will need to conduct a benchmarking exercise to compare its prices against both the water utilities and the water sector. It has also been recommended that Umgeni Water reposition the professional services offered by the organization. This is because of a revelation by 18% (figure 10) of Water Services Authorities felt that the professional services offered by Umgeni Water do not meet their requirements. To improve this position, Umgeni Water should emphasize non-payment of its services provided unless they meet the required standard. The organization should also identify, amplify and communicate the benefits accrued through the professional services to these Water Services Authorities. Once the Water Services Authorities have realized the immense benefits that are accrued through these services and the insistence of honoring payments only after the quality of the final work produced has been acceptable, chances are greater for repeat business and this will ultimately lead in Umgeni Water being recognized as the preferred provider of services. / Thesis (M.B.A.)-University of KwaZulu-Natal, Pietermaritzburg, 2004.

How do water companies adapt to climate change impacts?

Weber, Marie-Christin 08 May 2014 (has links) (PDF)
The primary objective of this work was to analyse how water companies are affected by climate change and how they try to adapt to it. Therefore, a systematic literature review was being accomplished. The work is being divided into a theoretical and a methodological part. First of all an overview of the climatic changes that are projected to occur during the next years is being given. Then, resulting impacts on the water cycle are being pointed out. Furthermore, raw water sources, water companies obtain water from are being defined as well as the treatment process. Within the methodological part the approach of a systematic literature review is being applied, which includes the selection of references as well as their evaluation. The results of the literature review are that concerning the effects of climate change on water companies, the risks water providers might face, clearly predominate possible opportunities. Especially the deterioration of the raw water quality caused by increasing temperatures, floods as well as heavy rainfalls can be seen as a serious problem. Moreover, the most often mentioned adaptation strategies are dealing with quantitative water problems such as measures to increase storage as well as treatment capacity or leakage reductions. All in all it can be stated that there is still uncertainty about how climate change is going to effect water companies, especially concerning water quality changes and the treatment process.

The bottled water industry in Mexico

Greene, Joshua Cullen 10 October 2014 (has links)
The bottled water industry in Mexico represents a new method of providing drinking water to a society without ties to a conventional central piped domestic water supply system. Mexico, the world's leader in bottled water per capita consumption, has struggled to provide reliable, safe drinking water for its citizens. This study examines the context in which the bottled water industry rose to become the primary source of drinking water for a majority of Mexicans. The study shows how the combination of factors allowed the industry's rapid rise from a niche market of elite and 'healing' waters to its present size. The cholera epidemic of the 1990s, the 1985 earthquake, and the financial crisis that left Mexico unable to invest in water infrastructure forced consumers to seek alternative water sources. Political factors and the liberalizing reforms of the 1980s, 1990s and 2000s facilitated market solutions and private-public-partnerships to meet the needs of the Mexican citizens. The world's largest food and beverage distributors bought into the market and found that the public was willing to pay cash for water bottles where the public water sector had failed to deliver potable water. Despite the fact that bottled water is more expensive per unit of water than a centralized delivery system, consumers are willing to pay a high price for clean water. It is an open question whether consumers return to tap water even after improvements have been made, once the bottled water industry has been so established. / text

Evaluation of the implementation of water and sanitation policies in a low-cost housing settlement of Ambleton and Ambleton Extension in Pietermaritburg, Msunduzi Municipality.

Zondi, Siyabonga Siboniso Goodman. January 2010 (has links)
The post apartheid government has been engaged in the process of delivering formal housing, water, and sanitation services to the poor. Because of huge backlogs in the provision of these basic services, the government has focused on meeting quantitative targets. The government has made significant strides to reduce the level of backlogs in basic service the delivery. However, there were challenges that confronted government in its endeavours to expedite delivery of services. The main challenge relates to the fragmentation in the funding mechanism for housing and the physical infrastructure, particularly water and sanitation infrastructure. Concerns have been raised about the ability of the local sphere of government to provide suitable land and quality physical infrastructure which were a prerequisite for sustainable settlements. The aim of the study was to evaluate the implementation of water and sanitation policies in a low-cost housing (LCH) settlement of Ambleton and Ambleton Extension in Pietermaritzburg. In line with the set objectives, the study attempted to find out if the implementation of water and sanitation policies in the area was consistent with the national policies and to establish whether or not people that lived in the area felt the quality of services has improved their lives. A qualitative methodology was used to collect data. In this regard three methods of collecting data were used, namely, semi-structured questionnaire, interviews and observation. The findings of the study showed that there were challenges with water and sanitation services. Some of the challenges relate to the inconsistent and fragmented nature of the funding mechanism that is inherent in basic service delivery policies. Residents of Ambleton and Ambleton Extension were generally unhappy about the quality of water and sanitation services. The study recommends that the government should revise its funding mechanism to strengthen the ability of municipalities to provide quality services. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.
