that need to be overcome in order to standardize sustain-
able and efficient water use. For small mining companies
with limited resources, the introduction of new technolo-
gies and systems is not an easy task. IoT-based monitoring
and control require additional financial investments, such
as the purchase and installation of sensors, the development
of centralized control systems and the continuous main-
tenance of equipment. Furthermore, the complex nature
of IWM and the use of new technologies requires specific
expertise, which is difficult to obtain given the general
shortage of skilled labor in the industry. Small companies
may not have the necessary technical know-how or human
resources to develop and operate such a comprehensive sys-
tem. Bringing in external consultants or experts can further
increase costs and complexity.
Regulatory hurdles also pose a significant challenge.
Complying with multiple environmental regulations and
international standards can be particularly difficult for small
businesses. These regulations change frequently and require
constant monitoring and adjustment of operating practices.
The administrative burden and legal requirements associ-
ated with implementing an IWM can be overwhelming.
The acceptance and cooperation of all stakeholders, includ-
ing local communities, governments and environmen-
tal organizations, are also critical to the success of IWM.
Resistance to change or lack of cooperation can hinder
the implementation of IWM. Extensive communication
and negotiation are required to ensure that all stakehold-
ers understand and support the benefits and needs of inte-
grated water management. However, this requires a high
degree of transparency, which is not favored by all investors
and mine operators and can also exacerbate conflicts.
To overcome these challenges and promote IWM
in the mining sector, policy measures play a crucial role.
Governments should provide support programs and subsi-
dies to help small mining companies in particular to imple-
ment IWM. Clear and consistent regulatory frameworks
that promote the implementation of IWM are also neces-
sary. Public-private partnerships can support the develop-
ment and diffusion of IWM technologies by promoting
research and development and facilitating knowledge trans-
fer between different actors. Research initiatives play a key
role in the further development and implementation of
IWM. Interdisciplinary research teams combining exper-
tise from the fields of engineering, environmental sciences,
economics and social sciences are needed to develop com-
prehensive solutions to water management challenges. Pilot
projects and case studies can provide valuable insights into
the implementation of IWM in different contexts and help
to identify and disseminate best practices. Comprehensive
cost-benefit analyses can help mining companies realize the
long-term economic benefits of IWM, including potential
savings from improved water efficiency and the avoidance
of environmental penalties.
Summary and Outlook on IWM
Integrated water management (IWM) in the mining indus-
try faces multiple challenges that have evolved over the
years. Traditional issues such as mine drainage and ensuring
water quality remain, but new factors such as global warm-
ing and geopolitical uncertainties have introduced addi-
tional complexity. Climate change leads to unpredictable
fluctuations in water availability and increases competition
for water resources between mining, agriculture, cities and
ecological systems. These developments are forcing mining
companies to factor both water surpluses and droughts into
their planning. The production of minerals for renewable
energy technologies is expected to increase by 500 %by
2050, which will significantly increase water demand. At
the same time, mining companies need to reduce their CO2
emissions and adopt more sustainable practices to sup-
port the United Nations Sustainable Development Goals
(SDGs). The focus is on ensuring sufficient water resources,
improving resilience to climate-related hazards and mitigat-
ing negative environmental impacts. A modern IWM relies
on a holistic approach that takes hydrological, climatic and
socio-economic processes into account. It includes risk-
based assessments of water quality and quantity to manage
the impacts of anthropogenic and natural processes. The
early involvement of stakeholders is crucial to minimize
conflicts of use and identify synergies. Probabilistic water
balance models and real-time data help to assess the overall
performance of the water management system and perform
sensitivity and risk analyses.
When planning a mine according to the Blue Mining
concept, comprehensive water management strategies must
be considered in the early stages in order to avoid costly
subsequent adjustments. This includes the systematic
planning of the water infrastructure, the consideration of
socio-economic aspects and the involvement of local com-
munities and authorities. It is also important to assess the
impact of climate change on water availability and quality
and to develop appropriate countermeasures. Throughout
the life cycle of a mine -from the exploration phase to clo-
sure -continuous data collection and analysis plays a cen-
tral role. This helps to refine water balance models, adapt
management plans and ensure transparency to stakehold-
ers. During the closure phase, it is critical to continue to
make good use of existing infrastructure and develop sus-
tainable water use strategies that continue to make positive
