Yes, we deliver to all nine provinces including remote and rural areas. We work with a network of logistics partners to ensure reliable delivery across South Africa. Delivery costs vary based on location and tank size — contact us for a specific quote.
All above-ground tanks require a flat, level, and compacted base. For tanks up to 5 000L, a well-compacted sand pad is usually sufficient. Larger tanks (10 000L+) should be placed on a reinforced concrete slab. We provide detailed installation guidelines with every purchase.
Various government and municipal programmes offer subsidies for water infrastructure, particularly for agricultural and community projects. The Department of Water and Sanitation administers several such programmes. Agricultural operations may also find relevant funding opportunities through agricultural grant directories. We recommend contacting your local municipality for region-specific rebate information.
Reliable water storage is transformative for underserved communities. It provides consistent access to clean water for drinking, cooking, and sanitation even during supply interruptions. Many community projects combine bulk storage solutions with government assistance programmes. For households facing financial difficulties, resources such as social relief support information can help families access the assistance they need while securing basic services like water.
