There is wide spread interest in water conservation and specifically in capturing and reusing rainwater in both residential and commercial buildings to reduce costs, reduce the environmental impact of the building and lessen the load on the municipal sewer and stormwater systems in the arid southwest where droughts are a way of life.
Harvesting rainwater from rooftops is one solutions to conserving our precious water, where it can be used instead of municipal drinking water for many non-drinking water (i.e. non-potable) applications (e.g. landscape, toilet flushing) as well as drinking water. There are two general types of rainwater catchment systems – “active” or “passive”. Most professionally installed systems incorporate aspects of both to maximize the water conserved.
Active rainwater catchment refers to systems that actively collect, filter, store and reuse water. The storage is usually the most visual aspect of an active system (i.e. large tanks), but they also generally incorporate pumps, and sometimes filters that require electricity (e.g. ultraviolet lights). These are active components that require regular ongoing maintenance to run efficiently and effectively. (Read the full article at the link below)
Mary Alford writes of one family’s experience in utilizing rainwater for all their needs, from watering the garden to taking showers and cooking. You can discover how they capture rainwater and store a 3 month supply, in the April edition of Natural Awakenings for North Central Florida, read it here.
