📋 Quick Answer
Big Ditch Dam Building Company has been constructing and repairing farm dams across New South Wales, Queensland, and Victoria for over 35 years. Every farm dam built to the right standards — correct clay, proper compaction, adequate spillway — can provide 50–100+ years of reliable water storage.
Orange might be the new black, but natural swimming pools are the new black when it comes to innovative dam design and dam construction Natural swimming pools can be formal or entirely natural, and they are designed as a refuge and place of recreation while operating as a beautiful and regenerative water garden. The feeling of swimming in pure water is incomparable.
Why it’s worth to consider natural swimming pools?
Natural pools are examples of how we can harness nature’s intelligence effectively. The peaceful water adds a new dimension to the garden, creating a calming and soothing effect. A natural pool will look stunning throughout the year and is also an effective way to enhance the beauty of your garden in the winter. The concept of designing for both aesthetics and functionality in dams started in California, where the dam feature was moved closer to the house than traditionally located.
From a design perspective, natural swimming pools feature low profile dam walls with minimal freeboard to achieve an infinity pool effect, soft edges – sometimes combined with hard edges – and rocks are often used as a highlight feature, but also as natural floor filtration.
Why these pools are so good?
Natural swimming pools are not as deep as dams to ensure water clarity and safety. In the planning of natural pools, generally the ratio of the swimming zone to the regeneration zone is 1:1 and the depth is only two meters in the swimming zone. Natural swimming pools are built to operate using the same biological principles and functions that Mother Nature uses to clarify and purify natural bodies of water like ponds, streams and lakes.
A natural swimming pool is a biologically active living system which provides the conditions for an ideal mix of beneficial microorganisms, aquatic flora, and fauna. Impurities are absorbed by the plants as nutrients and harmful bacteria are destroyed by natural water organisms.
Moreover, they are intended to be maintained without any chemicals and/or devices that would kill bacteria, microbes, animals, or plant life. The filtration, cleaning, and clarifying of bathing water takes place purely by hydraulic and biological processes. And talking about the plants, it may happen that you are not ready for maintaining the pool but still want to сonnect with nature. In this case, you can turn your dam into a water garden.
