辅导 CIVE5320M & CIVE5321M - Water Supply调试SPSS

Design coursework for Water Supply module in water, sanitation and health (WASH) programme

Rationale

Water supply is a crucial infrastructure with direct applications in solving water, sanitation and health (WASH) challenges. With water scarcity and quality concerns becoming increasingly prevalent, it is essential to educate the next generation of engineers on the design and operation of sustainable water supply systems. This coursework will foster an interdisciplinary approach by combining principles of civil engineering, hydraulics,  health, risk, and sustainability. Such an approach aligns with the evolving demands of the field and equips students with a comprehensive skill set. By incorporating design and operational aspects  in assessment coursework, students will gain  hands-on experience in water supply systems. This coursework will try to introduce students to the global variations in water supply challenges. Incorporating this coursework will not only contribute to students’ skill development but also provide students with a valuable educational experience of designing water treatment and distribution systems in a global context.

Brief

Huarmaca is a district in the province of Huancabamba, located in the Piura region of northwestern Peru. The local government of Huarmaca has commissioned a project to improve the water supply for households surrounding the town of Tunaspampa. The project aims to provide a stable supply of safe, potable water to all households in Sector I to Sector IV of this localities.

To achieve this, treatment processes must be established to ensure the water is safe for human consumption, and a piped distribution system must be designed to connect the treated water supply to individual households. A location map is provided in Annex A, showing the project's area. Annex B contains details of the sectors with households requiring water supply. The source of water will be a spring, identified as BM-1 in Annex B. The coordinates of the spring are [Latitude: -5.6946, Longitude: -79.5150], allowing you to locate it on universal mapping platforms to familiarise yourself with the geography of the area. The spring is capable of meeting the entire water demand of the region.

Annex C includes a drone-based topographic map of the area, showing altitude information. This should guide both the conceptual and detailed pipeline design decisions. Note that the coordinates in Annex B and Annex C use the standard UTM system, which must be converted to latitude and longitude for use on platforms such as  Google Maps. High-quality versions of the maps provided in Annexes A to C are available  for download on Minerva under the Assessment and Feedback folder.

The region lies in a tropical zone. While the climate is primarily warm and dry (with average rainfall of 20 mm per month), intense rainstorms occasionally occur throughout the year. Additionally, there is a rainy season lasting four months, during which the average rainfall increases to 100 mm per month. Table 1 presents the characteristics of water samples collected from the spring during the two principal seasons.

Table 1: Characteristics of spring water samples during the two principal seasons

There are periodic interruptions to electrical power and the supply of chemicals in the region, which should be considered when designing the system. The number of households in Sector I and Sector II is indicated on the map, with specific buildings serving key community roles: Building 15 is a primary school, and Buildings 16, 41, and 43 are community centres. The population per household is provided in a table in both Annex B and Annex C, covering buildings numbered 1 to 47. Your designed water distribution system must supply water to all 47 buildings listed in the table. The primary school (Building 15) must accommodate water for 60 students from the surrounding area, and each community centre (Buildings 16, 41, and 43) must be capable of supporting a supply for 20 individuals.

When designing treatment processes, if a centralised treatment plant is proposed, it must be economically viable. This requires accounting for future population growth across the region, based on your proposed design life and growth rate. Population growth is assumed to be 3% per annum.  Both the  treatment plant/process and the water distribution network must be designed to withstand future developments, including the impacts of climate change and increasing population.

The locations, sizes, and specifications of any treatment works and pipes within the water treatment and distribution  system  are  to  be  determined  by  you.  However,  it  is  critical  that  the  design  accounts  for population growth over the entire design life to ensure feasibility. Designs that fail to address these factors will not meet the requirements of the local government.

The local government mandates that all water supply systems must guarantee a continuous supply of water (non-intermittent) that meets World Health  Organisation (WHO) standards for water quality. These standards have been formally adopted as the Peruvian national standard. Compliance with these standards is a key requirement for the project.

Please prepare a report for the local government of the Huarmaca district outlining a proposal for appropriate water treatment and  distribution systems for the Tunaspampa  region.  The  report  should include recommendations for management arrangements, with a focus on ensuring that the entire system is operated and managed locally. You must propose methods for managing the operation of the treatment and distribution system. The proposal must ensure the delivery of safe and effective   potable water throughout the year.

Your report should present a detailed proposal for the treatment and distribution system, incorporating the following technical elements:

• Main Elements of the Treatment System: Provide a detailed explanation of the primary components of the  proposed  treatment system, including the  approximate size, capacity, and  role/function of each individual unit.

• Piped Distribution System Design: Include a design for a piped distribution system that connects treated water to individual households. This design should be justified with appropriate calculations and hydraulic models. You must simulate the system using suitable software, such as EPANET, and include the simulated network and results in your report.

• Operation Key Aspects: Describe the key operational aspects of the system, including methods to address interruptions  in  electricity supply or chemical availability. Highlight any differences  in operational requirements between the dry and rainy seasons.

• Potential Concerns and Solutions: Summarise potential challenges that could affect the operation of the system and provide recommendations for addressing these concerns.

Clearly state any assumptions made in the design of the treatment and distribution systems. Additionally, briefly explain the advantages of your proposed solution compared to alternative approaches.

You are strongly encouraged to discuss how your proposed solution contributes to achieving Sustainable Development Goals (SDGs). Furthermore, consider integrating recent advances in smart systems into your design and discuss the potential benefits of incorporating smart water system technologies.
