Abstract:
Small Island Developing States (SIDS) have unique challenges in water resource management due to their small geographical area, reliance on fragile ecosystems, and vulnerability to climate change. This paper presents an Integral Urban Water Treatment Plant (WTP) Design Guide to enhance water circularity as a long-term solution for SIDS. The guide emphasises the integration of water treatment, water circularity, and nature-based solutions that can be easily adapted to Caribbean SIDS’s unique geographical, social, and economic conditions. By fostering circular water techniques with conventional water treatment processes, water harvesting and sustainability. This design guide focuses on water resources provisions from rivers, groundwater reservoirs or dams in the West Indies and critical infrastructure requirements which provides long-term viability of potable water supply. Benefits of the suggested WTP design includes step-by-step processes for improved water security, increased resistance to climatic changes, and less dependency on external water supplies. The paper presents a replicable paradigm that can be easily applied across Caribbean SIDS to promote sustainable development and self-sufficiency in urban, sub-urban integrated water resources management (IWRM).
Keywords: Small Island Developing States (SIDS), urban water treatment plant, design, sustainable development, climate resilience, West Indies Integrated Water Resources Management (IWRM).
Streszczenie:
Małe rozwijające się państwa wyspiarskie (SIDS) stoją przed wyjątkowymi wyzwaniami w zakresie gospodarki wodnej ze względu na niewielki obszar geograficzny, zależność od wrażliwych ekosystemów i podatność na zmiany klimatu. Niniejszy dokument przedstawia kompleksowy przewodnik projektowania miejskich stacji uzdatniania wody (WTP) w celu poprawy obiegu wody jako długoterminowego rozwiązania dla państw wyspiarskich. W przewodniku położono nacisk na integrację uzdatniania wody, obiegu wody i rozwiązań opartych na naturze, które można łatwo dostosować do wyjątkowych warunków geograficznych, społecznych i ekonomicznych karaibskich państw. Poprzez promowanie technik obiegu wody w połączeniu z konwencjonalnymi procesami uzdatniania wody, zbieraniem wody i zrównoważonym rozwojem. Niniejszy przewodnik koncentruje się na zasobach wodnych pochodzących z rzek, zbiorników wód gruntowych lub zapór wodnych na Karaibach oraz na krytycznych wymaganiach infrastrukturalnych, które zapewniają długoterminową rentowność dostaw wody pitnej. Korzyści wynikające z proponowanego projektu WTP obejmują stopniowe procesy poprawy bezpieczeństwa wodnego, zwiększenia odporności na zmiany klimatyczne i zmniejszenia zależności od zewnętrznych dostaw wody. Dokument przedstawia powtarzalny paradygmat, który można łatwo zastosować w małych rozwijających się państwach wyspiarskich regionu Karaibów w celu promowania zrównoważonego rozwoju i samowystarczalności w zakresie zintegrowanego zarządzania zasobami wodnymi (IWRM) w miastach i na przedmieściach.
Słowa kluczowe: małe rozwijające się państwa wyspiarskie (SIDS), stacja uzdatniania wody, projekt, zrównoważony rozwój, odporność na zmiany klimatu, zintegrowane zarządzanie zasobami wodnymi (IWRM) na Karaibach.
