Abstract:
Introduction.
One of the challenges in achieving goal N6 of the 2030
Agenda for Sustainable Development "Ensuring the
availability and sustainable management of water and
sanitation for all" is to reduce twice the amount of
untreated wastewater discharged into the
environment.
Purpose
of the study is to assess the quantitative and
qualitative features of wastewater management in the
Republic of Moldova by determining the directions for
reducing the untreated water discharge.
Material and methods.
A descriptive study was performed. The object of the
study was quantitative and qualitative indications of
wastewater and data on sewerage networks and
treatment plants in terms of antibiotic resistance.
Results.
The impact of wastewater on population health is determined by
environmental pollution with pathogens, heavy metals, petroleum
products, detergents, pharmaceuticals, as a result of the lack of
centralized wastewater collection systems and treatment plants,
the use of inefficient treatment technologies. In the republic, only
8.7% of the localities have access to public sewerage systems
(94.5% - urban and 5.5% - rural), which collect on average 70.1
million m3 of wastewater annually, of which 96.9% are treated.
The share of non-compliant treated wastewater samples at
discharge was 37.5% - microbiological parameters and 78.1% -
chemical in 2021.
Conclusions.
In order to ensure the harmlessness of wastewater on the
environment and the population health, an intersectoral
involvement is necessary through development of sewerage
networks, implementation of cost-effective treatment
technologies and strengthening the phenomenon of antibiotic
resistance.
