Rainwater harvesting is a technique where rainwater is collected and stored in a water tank for future use. Basic uses include watering your garden, topping up your swimming pool, washing your car, flushing toilets and, if it is filtered, for use throughout the home. There are many benefits of rainwater harvesting. Here are just 5 examples of why it is something you should consider:
Swimming pools waste on average up to 500 litres of backwash water per week on cleaning the filtration system. Aquarista offers an affordable solution that clarifies backwash water and returns the water safely to the pool.
Backwash water from the pool contains toxic chemicals that are environmentally unfriendly. This water is either erroneously wasted to storm water, ending up in rivers and estuaries, or is wasted to sewer placing unnecessary pressure on waste-water treatment plants, which are already over-burdened.
Each year the City of Cape Town updates their annual water and sanitation charges at the start of July. Due to current water scarcity, the City of Cape Town has imposed a 20% water restriction. Below is a breakdown of these charges for single residential homes.
The domestic single residential sanitation tariff remains linked to the water tariff at a rate of 70% of water consumption (70% of 50kl = 35kl). This means that water used for garden irrigation is charged based on 70% of water consumption, even though this water never reaches the waste-water treatment works.
