Vestelli Closed tank 12 m\u00b3 fiberglass for cottages and detached houses – a spacious and cost-effective solution<\/strong><\/h3>\n

Vestelli Closed tank 12 m\u00b3 fiberglass for cottages and detached houses offers a very spacious and environmentally friendly solution for storing wastewater. The large 12 m\u00b3 capacity is optimized for the emptying capacity of the most common sewage trucks (12\u201315 m\u00b3), \u200b\u200bwhich reduces the number of emptyings and reduces costs in the long term. By choosing this model, you save both money and nature, as the need to empty is 20% less often compared to a traditional 10 m\u00b3 closed tank. <\/p>\n

Durable and reinforced fiberglass construction<\/strong><\/h3>\n

The tank is made of fiberglass that meets pressure class 2 requirements, which is resistant to long-term use and challenging conditions. The structure is designed to withstand normal installation up to a depth of 1.5 meters, so it is also well suited for sites where sewers run deep. The tank can be anchored securely with tow ropes or a separate anchoring fabric, and the delivery also includes a wireless full alarm to ensure worry-free use. <\/p>\n

Long emptying intervals \u2013 less emissions and costs<\/strong><\/h3>\n

Thanks to its volume, the Vestelli Closed Tank 12 m\u00b3 significantly reduces the need for emptying. This means lower transport emissions, fewer operating costs and savings in emptying costs. Due to its large capacity, it is ideal for permanent homes, second homes and locations where water use is high. For cottage use, a smaller 5 m\u00b3 or 10 m\u00b3 tank is often sufficient, but 12 m\u00b3 brings clear savings in the long term. <\/p>\n

Suitable for dual drainage and groundwater areas<\/strong><\/h3>\n

Vestelli Closed Tank 12 m\u00b3 can be connected as part of a dual sewer system, where toilet wastewater is directed to a closed tank and greywater is treated with a separate system, such as Biopurifier 3.<\/a><\/strong> This combination offers a cost-effective and environmentally friendly solution even in areas with stricter regulations. The tank is also suitable for groundwater areas, where all wastewater can be safely directed to a closed tank without environmental impact. <\/p>\n
