TECHNICAL REPORT ON DESIGN OF AN APPROPRIATE DECENTRALISED WATER & WASTEWATER MANAGEMENT SYSTEM
TECHNICAL REPORT ON DESIGN OF AN APPROPRIATE DECENTRALISED WATER & WASTEWATER MANAGEMENT SYSTEM NOTE:
This is an open-ended design assessment. You can assume the data; however it should be justifiable and well-referenced. An isolated community away from an urban area is being developed. It is estimated that the land area of 50 hectares will be divided into 10 lots, each lot not being equal. The developer is still undecided about the water supply system. There is a fresh-water lake that is very close to the community; partly on the land area owned by the residences and partly on government land. The majority of land has a clay loamy structure of moderate permeability. It is estimated that water consumption is each house will not be greater than 200 L per person per day, and each house will be designed for 5 people. You are required to use typical water usage data (purpose & quantity). Assume that the maximum number of people at any given time can only go up to 8 in a house. You have been hired as a consultant by the developer to provide assistance on designing a water and wastewater management plan for the development. You are required to write a technical/feasibility report on designing this system. Your report should highlight: – Your role (How would you go about the project, what data would you collect & why?) – Your knowledge of different water and wastewater treatment systems – Demonstration of your knowledge of design of systems: (a) Describe two conceptual designs of water/wastewater management. The residences are environmental conscious and would like to see the inclusion of water conservation, reuse and sustainability in the designs. You are required to provide a brief description of each of the designs you developed and give a schematic diagram. (b) You are then required to choose the ‘best’ option and give your reasons for this. Provide detailed design of the different units in the wastewater management scheme. This part of your report should include: – Assumptions you make from (a) readings and (b) class lectures should be clearly stated and properly referenced. – Quantity of water usage – Quality of water to be used – Quantity of wastewater generated – Quantity of wastewater that will be reused – Quality of wastewater after treatment – Type of process selected – Determination of capacities or volume or sizes of each unit in the process scheme with appropriate assumptions of design criteria for each unit – Details of the design using plan, section and side view sketches/drawings. (c) Your role in this project is not only that of a designer, but you also need to liaise with different stakeholders. Your report should therefore describe the different issues that you need to discuss with each stakeholder for this developmental project. This report should be well structured and easy to read, and should not exceed 10 pages in length (12pt font, single-spaced). Please provide all references, sources, and personal communications you have with any one. The list of references, table of contents and any appendices are excluded from the page count. Please note that this is an individual assignment. All information provided must be original.
