The use of treated wastewater to irrigate the sugar beet (<em>Beta</em> <em>Vulgaris</em> L. var. saccharifera) for bioethanol could play a strategic role to contrast the use of natural water resources and increase the productivity of the crop. The 2-year experiment (2013-2014) was performed on sugar beet irrigated with fresh water and wastewater at different steps of the reclamation process (secondary and tertiary treatments). The data obtained showed that the root sugar beet yield and ethanol production under fresh water treatment (52.2 Mg ha<sup>–1</sup> and 5446 L ha<sup>–1</sup>) were lower respect to that obtained from the secondary and tertiary wastewater treatments (66.7 Mg ha<sup>–1</sup> and 6785 L ha<sup>–1</sup>, and 58.7 Mg h<sup>–1</sup> and 6164 L ha<sup>–1</sup>, respectively), with the same irrigation volumes. These results can depend on the higher quantity of nutrient uptake when wastewater is used for irrigation. In particular, the average N applied (as nitrate and ammonium) with irrigation during the growing seasons (2013 and 2014) was corresponding to the supply of 4, 28 and 20 kg ha<sup>–1</sup>, for the fresh water, secondary, and tertiary wastewater treatments, respectively.

Lake Size

This study aims to develop a dynamic system model that describes the relationship ofwater, socio-economic, and water resources (lake size) sub-systems in Situ Binong. In addition,this study also aims to make predictions of water resources conditions (lake size) Situ Binong forthe next 5 years. The model is prepared using a dynamic system approach. The Situ Binong waterflow model is available water resources consisting of 3 sub-systems namely natural water flowsub-systems, socio-economic, and water resources Situ Binong. The result of the research showsthat the requirement of Situ Binong water resources every year is increasing so that the volume ofSitu Binong is decreasing. In addition, the volume of water resources Situ Binong influenced bysupply and demand. Supply comes from domestic waste and natural water flow such asprecipitation, infiltration and surface flow. While demand comes from WTP intake, irrigation, andevaporation.

The Difference

&lt;p&gt;Using reclaimed water as a resource for landscape water replenishment may alleviate the major problems of water resource shortages and water environment pollution. However, the safety of the water and the risk of eutrophication remain doubted by the public. Our study aimed to reveal the difference between natural water and reclaimed water and to discuss the rationality of reclaimed water replenishment from the perspective of microorganisms. We analyzed the microbial community structures in natural water, reclaimed water and natural biofilms and the community succession was clarified along the ecological niches, water resources, liquidity and time using 16S rRNA gene amplicon sequencing. Primary biofilms without the original community were added to study the formation of microbial community structures under reclaimed water acclimation. The results showed that the difference caused by ecological niches was more than those caused by the liquidity of water and different water resources. No significant difference was found in the microbial diversity and community structure caused by the addition of reclaimed water. Based on the microbial analysis, reclaimed water replenishment is a feasible solution that can be used for supplying river water. Innovatively, we introduced the study of biofilms and determined that the monitoring of biofilms or sediments closely related to water was also important for the early warning of water bloom, providing a unique perspective for the management of eutrophication.&lt;/p&gt;

The Impact

Lifecycle assessment (LCA) is a standardised methodology that is used to assess the impact of techno-economic systems on the natural environment. By compiling an inventory of energy and material inputs and environmental releases or outputs of a system, and evaluating the potential environmental impacts associated with the inventory, one can make an informed decision regarding the sustainability of a techno-economic system in question. However, the current lifecycle impact assessment (LCIA) methodologies that form part of LCA studies do not effectively consider the impacts of techno-economic systems on ground and surface water resources in South Africa (and elsewhere). It is proposed that a microbiology based index method, similar to methods proposed for terrestrial resources, can establish the states of water resources for six classes of current economic exploitation: protected, moderate use, degraded, cultivated, plantation, and urban. It is further suggested that changes in these classes (and states) can be used meaningfully in LCIA methodologies to quantify the extent to which techno-economic interventions may alter natural water resources. Research is recommended to further improve the accuracy and reliability of the water state index.
