The contents of this thesis deal with the complete design of a water supply system for a typical small-sized teeming modern Chinese city with a population of about 30,000. A fictitious map of the city with contour lines and all the necessary details was prepared for this purpose. The factors of construction, distribution and sanitary aspects are considered in the design. Theories and methods are fully explained whenever seems advisable.

M.Tech. / The Water Services Authorities in South africa are currently responsible for the management and operation of rural water supply in the country.Many of these comunity water supply schemes are in poor conditions due to lack of proper operation, maintenance, poor design and/or poor construction with the result that they experience serious water losses through physical losses(leakage)and apparent losses, and often fail to meet the consumer's demand during peak periods.Indications are that substantial quantities of water are lost in the systems due to leakage, wasteful use, illegal connections and meter errors. As a result of these problems, the levels of service delivery are often very poor leading to low cost recovery resulting in water services institutions becoming ineffective and inefficient businesses. The investigation attempted to identify effective techniques and/or strategies for water loss reduction in Dinokana Village (Central District Municipality). The study identified and defined various procedures/methodologies for managing Non Revenue Water in community water supply schemes. Some of the strategies developed from the findings of this research have been implemented with a view of quantitatively verifying their effectiveness.

A water supply tariff is a powerful water management tool that can be used to promote a number of economic, environmental and social-political objectives. In South Africa, increasing block tariffs are deemed to satisfy the domestic tariff regulations of the Water Services Act of 1997. The regulations require that the tariff supports the viability and sustainability of water supply services to the poor and discourages wasteful or inefficient water use. The application of increasing block tariff structures presents a number of problems. The main issue being the size and price of each block. Ramsey pricing proposes that consumer welfare is maximised when the mark-up in price above cost of a good is proportional to the price elasticity of demand of the good. This principle was applied in setting the block prices of an increasing block water tariff. The sizes of the blocks were based on the average water consumption of low, middle and high income consumers. The water demand characteristic of low, middle and high income households from a sample of domestic consumers in Durban were investigated. The water demand functions and price elasticity of demand for the three groups were estimated using econometric models. Two tariff structures based on Ramsey pricing principles were proposed and compared with the current increasing block tariff applied in Durban. The frequency distribution of demand of each of the three consumer groups were applied in a model to ensure the proposed tariffs met a certain revenue target. The water demand functions of each of the consumer groups were used to model how the proposed tariff structures impacted consumer surplus and water demand. The investigation found that increasing block tariffs designed with Ramsey pricing principles have a positive impact on social welfare, provide sufficient revenue for water service providers and support the conservation of water resources. / Thesis (MBA)-University of KwaZulu-Natal, Pietermaritzburg, 2003.
