    You’ve likely encountered the term “bunded” frequently when researching oil tanks. Essentially, a bunded oil tank features an additional outer tank surrounding the primary storage tank. This secondary containment serves as a protective barrier for the inner tank, effectively safeguarding the stored oil.

    It’s important to note that regulations regarding oil tanks vary by region. For instance, in Wales, specific regulations mandate that oil tanks must be equipped with bunding. This requirement ensures an added layer of safety and environmental protection, minimizing the risk of oil spills and contamination.

    Where should I put an oil tank?

    The placement of an oil tank depends on various factors such as local regulations, available space, and safety considerations. Here are some general guidelines for where to put an oil tank:

    1. Outside: Placing the oil tank outside, preferably in a designated area away from main living spaces, is common. This could be in the backyard, side yard, or another suitable outdoor location. Ensure the tank is positioned on a stable, level surface and protected from potential damage.
    2. Inside: If outdoor space is limited or not feasible, you can install the oil tank indoors. Common indoor locations include basements, garages, or utility rooms. Ensure the room is well-ventilated and meets any local building codes regarding indoor oil tank installation.
    3. Accessibility: Regardless of placement, the oil tank should be easily accessible for refueling, maintenance, and inspection. Ensure there is ample space around the tank for technicians to work safely.
    4. Distance from Structures: Whether inside or outside, the oil tank should be positioned a safe distance away from buildings, doors, windows, and other structures. This helps minimize the risk of fire or environmental contamination in case of a leak.
    5. Environmental Considerations: Consider the potential environmental impact of an oil tank leak when choosing the placement. Avoid placing the tank near water sources, sensitive ecosystems, or areas prone to flooding.
    6. Regulations: Check local regulations and zoning laws regarding the installation and placement of oil tanks. There may be specific requirements regarding setback distances, tank size, and placement options.
    7. Professional Advice: It’s advisable to consult with a qualified technician or oil tank specialist for guidance on the best placement for your specific situation. They can assess your property and provide recommendations based on safety, accessibility, and compliance with regulations.
