A type of wastewater reuse system for domesticity with remote-control is presented in this paper. For domestic water-saving, the wastewater reuse system is designed via hydromechanics, and its remote-control system is discussed. The system consists of wastewater storage tank, electromagnetic valve, electronic remote-control device, and pipelines. The principle of its water-saving is also analyzed in three control models. The results indicate that the wastewater reuse system can make the best of reusing domestic bathing and washing wastewater to wash down toilet bowl in order to save water supply. Electromagnetic valve is convenient to control and has good seal performance for avoid wastewater leak. Two enactment time control models and a manual control model can effectively satisfy with user, farther to save wastewater

Reuse System

For a sustainable urban future, society must move towards the goal of efficient and appropriate water use. Reuse of domestic greywater and rainwater has a significant role to play in this task. In this study, rainfall time series have been used in conjunction with estimates of domestic water appliance usage generated by the Monte-Carlo simulation technique to predict long term system performance. Model results show that changes in the attributes of household occupancy, roof area, appliance type and storage volume affect the water saving efficiency of a single store reuse system. Considering greywater and rainwater in combination, the greatest rate of increase of efficiency with storage size occurs in the range 0-100 litres. Further analysis of small volume storage and reuse indicates that savings of up to 80% of the WC flush water can be made with less than 50 litres storage. However, the collection of rainwater in addition to greywater in a single store reuse system offers little improvement in water saving efficiency. Small volume domestic water reuse systems lend themselves to application in the urban housing environment and therefore offer potential in the move towards a more sustainable city.

Domestic water supply and wastewater management are essential indicators of urban quality of life globally, and yet remain major environmental issues in Nigeria. The rapid growth in population has resulted in a higher rate of wastewater generation in Nigerian cities. However, many city plans are unable to cope with these issues appropriately. As a result, the poor management of wastewater is an ever-present problem with its attendant risks to public health and environmental safety. Therefore, this study attempts to analyse the control of urban development and management of domestic wastewater in Suleja, Nigeria. The study critically examines the current urban planning systems and presents an overview of selected technologies adopted for the decentralised treatment and disposal of wastewater in emerging nations. To this end, a documented and dissertation based analysis technique was employed in this study. Firstly, the paper begins by providing a methodical framework for comparative examination of the centralised and decentralised systems. The legal setting and policy framework, present city plan, and wastewater management are also explained. The study finds that loose development control and organic growth of residential development have a strong influence on wastewater management in the community

Background/Objectives: It is a common for existing golf courses to manage all lighting facilities in batches because it is hard to controllighting individually. That is very much part of the golf courses and forces the whole golf course to light on even though play was finished due to the difficulty of real time checking situationMethods/Statistical analysis: Lighting control device and method in this study are provided not only to control remotely individual lighting installed each hole in golf course but to inspect failure of lighting. There is no longer to stay golf course in person to control lighting system.Findings:Lighting control device and method to be able to control individual lighting installed each hole in golf course is provided to response for the problem in a waste of electricity after playing. User device makes it possible to remotely control lighting and inspect failure of itImprovements/Applications: It can expect to reduce golf course operation management cost by building a smart tower remote control system

Greywater Reuse

Domestic wastewater reuse is currently not permitted anywhere in Australia but is widely supported by the community, promoted by researchers, and improvised by up to 20% of householders. Its widespread implementation will make an enormous contribution to the sustainability of water resources. Integrated with other strategies in the outdoor living environment of settlements in arid lands, great benefit will be derived. This paper describes six options for wastewater reuse under research by the Remote Area Developments Group (RADG) at Murdoch University and case studies are given where productive use is being made for revegetation and food production strategies at household and community scales. Pollution control techniques, public health precautions and maintenance requirements are described. The special case of remote Aboriginal communities is explained where prototype systems have been installed by RADG to generate windbreaks and orchards. New Australian design standards and draft guidelines for domestic greywater reuse produced by the Western Australian State government agencies for mainstream communities are evaluated. It is recommended that dry composting toilets be coupled with domestic greywater reuse and the various types available in Australia are described. For situations where only the flushing toilet will suffice the unique “wet composting” system can be used and this also is described. A vision for household and community-scale on-site application is presented.

Removal of potential carcinogens and toxicants by a direct wastewater reclamation system and an indirect wastewater reuse system was evaluated by means of a sensitive golden hamster cell transformation assay. Representative water samples from various stages of both the direct and the indirect reuse systems were introduced to the hamster cells and changes in the rate and pattern of cell growth were observed. Both systems proved to be highly effective in their removal of potential carcinogens and toxicants and there is no indication that the slight toxic and transforming activity detected in their final water may constitute a health hazard.

Domestic Effluent

In the past sewage ponding in indigenous settlements was commonplace as a result of overcrowding combined with inappropriate septic tank and leach drain design, installation and operation. The response over the past 10 years has been to develop reticulated sewerage systems to lagoons when the funds become available. These are often successful in terms of operation, improved public health and low maintenance but are expensive and wasteful of limited water supplies. Evapotranspiration (ET) is an effective method for on-site domestic effluent disposal in areas of Western Australia with soils of low permeability. Evapotranspiration systems have been established in a number of communities both for research/demonstration and as specified by architects. The systems usually follow two septic tanks for the disposal of all domestic effluent. A case study will be presented for a remote indigenous community where the ET systems installed for greywater only have been monitored over the last two years since installation. The use of evapotranspiration has enabled reuse of effluent for successful examples of revegetation and food production and points to the need for a holistic approach to design and service delivery in these communities that includes a total environmental management plan.
