Made from 100% virgin food-grade polyethylene, UV stabilised, one-piece moulded construction with no seams or joints. Opaque design prevents algae growth. Slim vertical column design ideal for corner placement alongside walls or fences. Integrated filter system.Installation Process:Step 1 — Establish Rainwater Harvesting Capacity: Determine your roof area. Determine average rainfall per week from the Mauritius Bureau of Meteorology. Calculate tank capacity by multiplying roof area by average rainfall. Example: a roof of 100m² with 25mm average rainfall yields 2,500L — required tank capacity is 2,500L.Step 2 — Select the appropriate model:– Column Type: 350L to 500L– Integrated Filter Type (Patented): 2500L to 9000L– Slim Rainwater Tank: 1200L– Underground Rainwater Tank: 4700LStep 3 — Accessories required: Water pump and level indicator (sold separately).Step 4 — Site Preparation: Place the tank on a solid levelled concrete base. Clear roof guttering of leaves and debris — adjust guttering if needed to direct water to the tank location. Design tank overflows to prevent stormwater ponding under the concrete base or flooding foundations.Step 5 — Distribution: The system diverts the first 60 litres of each rainfall event to ensure a cleaner supply. Select a pump and filtration system to distribute water inside or outside the home. Connect to washing machine, toilets, or outside gardening tap.Installation Rules: Tanks must NOT be installed on rocky/uneven surfaces or on blocks and metal frames. Always place on a flat, smooth concrete surface. Outlet must be well supported. Note: these tanks are not designed for underground installation — except the Underground Rainwater Tank 4700L.Warranty — 12 Years (above-ground models):– Years 1–4: Free replacement or free repair– Years 5–6: 85% discount off current retail price or free repair– Years 6–8: 70% discount off current retail price or free repair– Years 8–10: 55% discount off current retail price or free repair– Years 10–12: 40% discount off current retail price or free repairWarranty Exclusions:– Accidental damage, acts of God, misuse, or incorrect installation– Plumbing, fittings, float valve, outlet fittings and lid are not covered– Leakage resulting from wrong plumbing installation– Tanks used for storage of chemicals– Tanks not installed according to Duraco installation instructions– All tanks must be anchored on a smooth flat surface with no external load applied and inlet/outlet pipes adequately supported
