Water conservation and methods of green buildings are very important for them to have a sustainable structure. Therefore, below are some methods that can be used to conserve water in green buildings:
Prevention of leaks: Preventing leaks in buildings is important for the protection of water resources. Plumbing systems need to be checked regularly, leaks detected and repaired.
Low-flow faucets and shower heads: Low-flow faucets and showerheads reduce water usage while lowering your water bill. These heads maintain water pressure while reducing water flow.
Zero wastewater systems: Zero wastewater systems ensure the reuse of used water. These systems purify used water and turn it into usable water for garden irrigation or toilet flushing.
Twin-pipe systems: Twin-pipe systems reduce the use of fresh water for toilet flushes. In these systems, separate pipes are used for waste water and clean water. In this way, waste water is used instead of clean water for toilet flushes.
Rainwater harvesting: Rainwater harvesting allows rainwater to be collected and converted into usable water for garden irrigation or toilet flushing.
Xeriscaping: Xeriscaping is a landscape design used to reduce water consumption. This design includes the selection of plants used in arid regions and the use of soil with water-holding properties.
Grouped plant rain gardens: Grouped plant rain gardens allow rainwater to be collected and absorbed by plants. This system provides the feeding of underground water resources by absorbing the rain water in the soil.
The methods that green buildings can use to conserve water are quite diverse. Any of the above methods can be used by building owners and designers.
