Master of Engineering: Climate Change and Rainwater Tank Savings Study

This report evaluates the impact of climate change on rainwater tank savings in Sydney, Australia. The study includes an introduction outlining the research background, rationale, and objectives, emphasizing the significance of water scarcity. A literature review covers water sustainability, rainwater harvesting benefits and drawbacks, factors affecting adoption, design considerations, and global case studies. The methodology employs qualitative data collection and the e-Tank daily water balance model, analyzing data from 2020-2039 and 2060-2079 using various climate models and stations. Data analysis utilizes statistical methods, presenting results via tables and graphs in MS-Excel. The conclusion notes data inconsistencies, with Richmond RAAF showing the lowest water savings and Sydney Observatory Hill the highest. The report provides a comprehensive analysis of climate change's effects on rainwater harvesting in Sydney, offering insights into water conservation and sustainability.

Executive summary
The main aim of this study is to evaluate the effects of climate change on the rainwater tanks
savings in Sydney, Australia. This report has depicted many sections named as interdiction,
literature review, methodology, data analysis, results, discussion, and conclusions section.
Each section of this study is imperative for the researcher to comprehend the research
concern in depth. In the introduction section, research background, research rationale, and
research objectives have been discussed that could be an imperative part of the study. The
research background is effective to know how much climate change effects to the rainwater
saving. From the research, it is founded that water scarcity is being a problem for the current
period. This report also discusses the significance of the study. It also discusses the objectives
of the study. Under the literature review, many concepts have been discussed named as water
sustainability, benefits of rainwater harvesting, disadvantages of rainwater harvesting, and
factor affecting RWHS. It also discusses RWHS design, rainwater harvesting in certain
international cities, RWHS study in Australia, and climate of the Sydney, and daily balance
model. For conducting this study, the researcher has practiced the qualitative data collection
method has been practiced that enables to get conceptual information about the research
issue. In this study, e-tank with daily water balance model has been used to evaluate the
information and get the information about the effect of climate change on rainwater tanks
savings, Sydney, Australia. The data is estimated from 2020-2039 & 2060-2079. It is
evaluated that there are certain models that are considered by the researcher named as
CCCMA MK 3.0 + WRF R3, CSIRO MK 3.0 + WRF R3, ECHAM5 MK 3.0 + WRF R3 and
MIROC MK 3.0 + WRF R3. It is examined that certain station has been considered to
evaluate the effect of climate change on rainwater tanks savings named as Richmond RAAF,
Sydney observatory hill, Lucas Heights, Seven Hills, and Badgerys Creek. The investigator
has practiced certain steps to collect the data named as establish an account on New south

wales data portal website, start to collect the information, make data set, resolution and
domain, site-specific information, method, interpolation tool, targeted time, temporal
resolution, Precipitation data, and output format. This step is effective to comprehend the
research matter and support to have decision effectively. From the data analysis section, it is
founded that the statistical tool analysis method has been practiced to evaluate the factual
data. The data has been presented by a table and graph by considering the Ms-Excel software.
This software maintains the reliability of the data. It is evaluated that the water saving is
being an imperative concept in the current era. From the evaluation of the conclusion section,
it is founded that the data is inconsistent hat demonstrated that demonstrate the less reliability
in the result. It is examined that Richmond RAAF station is demonstrating the lowest water
savings as well as reliabilities outcomes while Sydney observatory hill station is the highest
water saving as well as reliability.
