Water Butts & Garden Watering

Here at Celtic Water we offer a comprehensive range of water butts and garden watering solutions. Water butts help reduce your water usage and help keep your garden thriving.

Rainwater is naturally soft, free from chlorine and other chemicals found in tap water, making it gentler on plants and soil life. It typically has a slightly acidic pH, which helps plants absorb nutrients more effectively.

We have a wide range of water butts particularly specialising in more decorative designs to suit any garden and aesthetic.

Explore our subcategories to find the perfect setup for your garden, from compact water storage options to complete rainwater harvesting kits.
