5 Water Supply Challenges and Achievements in Constanta County

tamination. New wastewater treatment plants are to be built in isolated areas (such
as Castelu-cluster Poarta Alba-cluster) and, furthermore, a new sectorisation of the
collecting areas [23] with a more appropriate distribution of waste flows to the plant
will be possible. Therefore, a reduced number of wastewater pumping stations will be
needed, due to local wastewater treatment, and the risk of long wastewater transport
conduits damage will be diminished. Furthermore, will be made a new investment in
the wastewater treatment infrastructure for towns with the population between 2000
and 10,000 equivalent inhabitants. Only the two new wastewater treatment plants
in the towns of Hârs , ova and B˘ aneasa will reduce the current volume of untreated
wastewater in Constanta County with approximately 78%.
Periodic inspections and sound plans to prevent and combat accidental pollution
have an essential role in the surface and groundwater sources protection. In areas
where nitrate values have already exceeded the maximum concentration allowed by
the standards, water wells will be deeper (Tortomanu 1000 m in depth and Braila
Island 500 m). Gleeson and Richter [10] suggest a new metric: the environmental
flow response time, that allows water managers to quantify the timescales of the
impacts of groundwater pumping. We strongly recommend this metric regarding
groundwater abstraction in Dobrogea.
As urban and rural water demand increases, it is of enhanced importance to ensure
the water quality and, at the same time, to prevent any possibility to pollute or
compromise the underground or surface sources. Industry and agriculture activity
may cause pollution, river regulation and hydraulic structures may also disturb natural
water circulation. Therefore integrated management for sustainable water sources is
the best way to preserve the environment.
New clean energy sources, like solar energy, have to be used in small irrigation
systems, taking into account that the insolation in the area is appropriate.
In the close future, other innovative solutions like precision pump control, and
irrigation on-demand method, are needed to replace current irrigation with an intelligent one. Desalinisation of brackish water and water reuse are also a must in the
context of freshwater scarcity foreseen by the experts.
In our world, where water and energy are more valued than ever, we must get
involved in solving efficiency issues and the authorities have to find the means to
implement new intelligent technologies.
5.6 Conclusions
The depletion of the groundwater quality is an ongoing phenomenon, which confined us, in Dobrogea, to use deeper aquifers for abstracting drinking water. This
phenomenon has to be stopped by better management of the pollution prevention
methods.
The poor quality of some water sources in the Southern part of Dobrogea and
the considerable increase of the drinkable water consumption during summer (when
the tourists come to the continuously extending resorts along the Black Sea coast)
