Constructed Wetlands (CWs) are currently one of the most promising techniques for wastewater treatment, having demonstrated their effectiveness. However, choice substrate particle size is critical to smooth operation process, as hydrodynamic constraints require a coarse size, whereas treatment recommends fine size. This study investigates suitability laterite and shale substrates different sizes (1 - 3, 3 5 8 mm) in CWs domestic treatment. The was carried out an experimental pilot plant consisting 12 parallelepiped beds (C × C = 0.4 m2; H 0.6 m) filled from bottom top with 0.1 m gravel or grain two replications. During six months operation, biomass stem diameter Pennisetum purpureum used vegetation were determined. Raw treated water also sampled analyzed pollutants, including chemical oxygen demand (COD), biochemical (BOD5), total Kjedahl nitrogen (TKN), phosphorus (TP), suspended solids (TSS), using International Organization Standardization (ISO) analytical methods. P. developed much better CW lined shale; ranged 13.8 14.7 kg/m2 11.2 12.5 laterite, respectively, did stump diameter, which 15.5 16.1 cm 11.10 12.7 cm, respectively. highest values each material obtained 1 mm geomaterials. Pollutant removal efficiencies (76.9% 83% COD, 78% 84.7% BOD5, 55.5% 72.2% TKN, 58.4% 72.4% TP, 78.1% 80.2% TSS), recorded shale-lined beds. both materials provided quality filtrates (140 174 mg/L 78.5 94.8 4.6 5.7 TP) line local discharge levels. geomaterials appears be suitable optimization purposes, although further work these materials, such increasing depth wetland, required improve level NTK TSS discharge.

The lack of access to centralized technologies and economic resources in rural communities makes wastewater management a critical challenge. Decentralized systems such as constructed wetlands offer sustainable solutions by leveraging natural processes for effluent treatment. However, their success sustainability require active community participation. Currently, there is little evidence involvement the implementation, maintenance, wetlands. Existing strategies collaboration environmental sanitation projects were analyzed through literature review covering research conducted last 20 years. Only peer-reviewed English Spanish was considered. Based on findings, triple helix model integrating academia, government, society proposed, compiling most functional from initial awareness raising maintenance dissemination. A case study participation presented under this approach Salvador Díaz Mirón community, Veracruz, Mexico. results provide key information effective designed manage wetlands, emphasizing that depends both technology genuine commitment operation long-term sustainability. Furthermore, these findings can serve reference decision-makers project planners seeking integrate participatory models into decentralized water resource conservation.

Constructed wetlands (CWs) attempt to simulate the physicochemical and biological processes that occur within a natural wetland have been employed in recent decades for wastewater treatment. This work aims review use of CWs domestic treatment undeveloped or developing areas, including amount literature produced, type constructed wetland, vegetation, substrate, social benefits achieved, through qualitative methodology where different articles are collected from Scopus Web Science databases after strict revision by means PRISMA method (Preferred Reporting Items Systematic Reviews Meta-Analyses) CASP (Critical Appraisal Skills Program). A total 49 were selected, co-occurrence density maps obtained; following this, three main themes five keywords with highest correlation identified. The analyzed this exposes types not only hybrid, vertical, horizontal flow systems stand out, but also floating aerated wetlands, which present high removal efficiencies. Additionally, new substrate materials, such as olote, palm shells, coconut peat, ornamental plants usually used, Phragmites australis Thypha latifolia, discussed; however, studies vegetation has little studied potential be implemented areas silvicultural characteristics out: Duranta repens, Pennisetum pedicellatum, Pistia stratiotes. In conclusion, there is an advancement research these systems, configurations, substrates, treat wastewater; addition, opportunity continue studying installation at household level; compared other application mentioned above, its implementation requires greater challenge, since it compact design easy handling.
