In this article integrated method of infrastructure asset management has been proposed by
AWARE-P which is a research based project. The proposed method had an objective to produce
sufficient and efficacious assisting techniques to support urban water facilities in taking decision
and reconstruction outlining. IAM methodology that was proposed addressed all three outlining
and decision phases i.e. strategic, tactical and operational and followed PDCA driven cycle. The
framework assessed water systems and the outlined explanations in context to cost, risks and
achievement elements with use of numerous standard evaluation tools and archetypes. AWARE-
P method that has been proposed incorporated values that are usually considered in IAM and it
approached IAM as a management procedure that was based on PDCA and required alignment
amid organization’s strategic goals and objectives and definite preferences and course of
activities executed. AWARE-P method took into consideration that a networked infrastructure
3

cannot be managed in similar manner as other compilations of physical assets and has an
assertive behaviour and on whole do not have finite life. AWARE-P method is prepared to
standardized assessment and compares intervention substitutes from performance, cost and risk
aspects. Hence it can be concluded that AWARE-P methodology aimed to develop awareness on
the need for efficacious infrastructure asset management, changing existing exercises and on
improved technical knowledge in water industry so as to offer guidance tool and technique. The
objective of AWARE-P method was also to promote and support urban water facilities in
executing a logical, organised process for Integrated Asset Management. AWARE-P
methodology is an innovative technique in IAM planning assessment as it can ensure that state of
the art technology platform use the best techniques for anticipating, determining and assessing a
specific urban water system with portfolio of achievement, risk and cost archetypes at both
universal and extensive level. This article has presented a good evidence that AWARE-P
methodology offers standard and lucid IAM planning technique that can be conveniently applied
to deal with utility issues in water management.

As pipelines in sewer water system hold for large part of overall costs of any conventional urban
wastewater system, treatment and disposal procedure so a lot of efforts are made to control costs
and balance revenue creation while offering appropriate levels of service to residents in context
of water management. So in this article concepts of asset management, methods and approaches
have been presented that are aimed to rejuvenate stocks of water pipelines so as to ensure capital
value and maintain performance levels. The article revealed that biggest challenge encountered
in water or waste water facilities is to find the right balance amid expenditures on maintenance of
network and spending’s on replacement of pipelines. So to ensure proper asset management of
these pipelines it is necessary that understanding of condition of pipelines is appropriate in
context to material, length and variable properties along with root intrusion etc. so that
4

conditions can be controlled and checked regularly. Also these information need to be adequately
incorporated in management activities so as to establish regular maintenance of water system
utilities. These will help to maintain capital value. Thus it can be concluded that adequate asset
management utilizes information about system performance and conditions to alter responses,
regular activities, process and capital investment so that these can avert occurrence of issues in
water system.

This article states that asset management is a rising problem for water and waste water sector and
a significant aspect of sewer asset management is assessment of physical quality of asset and
condition of grade to sewer segment. Whereas, quality evaluation of sewer segments depends
usually on observable investigation where each position grading parameter utilizes a distinct
initiative for consideration of visible damages. RERAU method has been applied in this article
which utilizes mean score. A strong linear relation amid overall score and segment length
determines capability of mean score to attribute a segment for specific dysfunction indicator. The
article has illustrated that strong linear relation is present amid total score of infiltration indicator
and segment length. Also the article has emphasized that most conventions allocate an indicator
to a grade by contrasting the mean score with subjective scale of numerical values and hence a
framework has been proposed in this article to actuate threshold for every particular asset stock.
The framework had certain leverages such as a calibration parameter used in method helped to
optimize and justify scale of numerical value. Another leverage is this method took into
consideration local parameters and sensitivity assessment allowed to tackle with uncertainty that
is linked with the parameter. The proposed calibration method also allowed threshold
computation as per two set of criteria i.e. total quality of asset stock and assignment-error
weights related to false positive and false negative inaccuracies. The first criterion either takes
hypothesis or is represented by representative sample of considered asset stock whereas later
5

criterion is determined by utility manager. Also the method depends on national sample
involving professional evaluation of a set of specified sewer segments. Also in this article it was
evident that regional precision should be taken into consideration as they impact scale of
numerical values applied to allocate an indicator to a grade. Outcomes of sensitivity assessment
of framework criteria showed that calibration procedure is susceptible to conditions of asset
stocks and weights related to assignment errors. These weights may be described almost ex
nihilo as they rely on approach of utility supervisor hence knowhow about total quality of asset
stock needs particular investigation campaigns so as to put together a representative sample. The
article also specified two primary fields of future research i.e. development of calibration
requisites in context to rising the size of national sample and substituting various evaluation of
professionals by continued disposal for all grade. The other area of research suggested is
describing methods to precisely evaluate total quality of asset stock and more particularly a
framework to describe representative sample.

This article stated that asset management is vitally significant for upkeep of integrity of urban
water infrastructures as high integrity infrastructure offers more soundness, amplitude and strong
efficiency which results into improvised service, low risk, higher safety, improved public health
and environmental stewardship as well as strong safeguard against flood damage. Also the
article stated that data gathering and administration are significant elements of asset management
so several state of the art technologies in data gathering, sharing and administration in distinct
elements of asset management for urban water systems have been useful. Some of these are
widely used in market and have been executed in Hong Kong, nonetheless, few of the
technologies of more calibre may need better development for practical outcomes. The Drainage
Service department in association with Water Supplies Department of Hong Kong has invested
6

and maintained an extensively big urban water infrastructure asset to offer state of art water
supply, waste water and storm water utilities to facilitate continued improvement of Hong Kong
Special Administrative Region. The article has presented the asset management of Hong Kong
SAR which has been effective due to elaborate planning, design and construction as well as
operation and maintenance. The effective asset management has enabled water supplies
department in Hong Kong to appropriately gather real time data, share and manage at distinct
interrelated operations of asset management which has contributed to efficacious operation of
asset management with adoption of technologies.
Conclusion
Thus it can be inferred that all articles have revealed that adequate asset management strategies
need to be administered in context of water supply management system in urban as well as in
sewer systems so that advanced understanding in this aspect can improvise condition of
management of water supply systems across all areas.
