Deliverable Report D3.2 LCA and LCC results

Two standardised analyses have been carried out to evaluate the cost and environmental status of the SERPIC system: Life Cycle Costing (LCC) is used to examine the cost of manufacturing and operating SERPIC systems, while Life Cycle Assessment (LCA) is used to analyse material and energy consumption, as well as the influence in the impact categories associated with the construction of the SERPIC prototype. These impact categories include carbon footprint, water footprint, human toxicity and impact on ecosystems. In addition to these assessments, a plan to manage the risk (the Sanitation Safety Plan SSP) in the case of reuse of reclaimed water must be developed, according to the EU regulation on reclaimed water reuse. The first step in this direction implies the evaluation of the main risks associated to the treatment. To pursue this aim, a Failure Mode, Effects, and Criticality Analysis (FMECA) was carried out and the effects of the failure modes of the different SERPIC treatment components were identified with regard the quality of the final effluent and its adequateness for irrigation needs. The analysis identified the main risks associated to the failure modes which may happen and which preventive measures should be to adopt to reduce them.
