Thus most of these plants are either inefficient or cause considerable strain on the operational cost. Thus several solutions in terms of sustainable sewage treatment methods have been proposed that takes into account the overall treatment efficiency and resource consumption. Thus the research work is planned to assess the sustainability potential of wastewater treatment plants in United Kingdom and attempts to generate the needed information for the promotion of sustainable wastewater treatment methods.
The treatment plants currently in operation are assessed for the existing state of operations. Also, their priority for setting up or converting the present systems into sustainable ones were also undertaken. The studies have also tried to evaluate a few of the technologies that are considered sustainable. The reed based treatment units consisting of naturally occurring agents - like microorganisms and small aquatic plants - was one such case considered here. This has helped to highlight the potential benefits and the limitations of these units have under the existing conditions in United Kingdom. The research also gives opinions on the on-technical interventions necessary for the large-scale acceptance of sustainable wastewater treatment methods. Hence, the outputs from this study would certainly be a pioneering one considering the sustainability component in the selection of environmental protection initiatives.
“Environmental sustainability” broadly involves all initiatives to maintain and protect the environment at a constant level without further aggravating the already damaged state of earth. The reports available shows that nearly 40 – 50 % of the global greenhouse gas emissions are from the building sector alone. Thus absence of any initiatives to reduce the greenhouse gas emissions would certainly accelerate the global warming
