Rainwater - perfect for home and garden

  • Rainwater - perfect for home and garden ?

    Save up to 50%

    Save up to 50% of City water and protect our environment.

    From an annual average rainfall collected from a 80m2 roof, four people could wash clothes, wash cars, flush the toilet and maintain a small garden, all year long. Harvesting rainwater is worthwhile for you and our environment.

    Your budget

    Water conservation program to suit your budget You save money by reducing your mains water consumption. Where mains water is used for toilet flushing, washing clothes, rainwater can be used, thus saving up to 50% of precious water. Rainwater is better quality than ordinary tap water as it is softer and therefore reduces limescale settlement, you use less detergent in the washing machine and less WC cleaner.

    Good reasons to use rainwater

    • Save money by reducing water consumption • Be independent of the water utilities and water price increases • Soft rainwater is particularly good for your plants • Contribute actively to the environment and conserve our precious water supplies • The sewage system is eased, because some of the rain water is collected and is not passed into the sewer system.

    Protect our environment

    How and at what cost are our vital resources being used today by all of us. City water supplies are vital and must therefore be secured for the future.

    For your house needs (WC and washing machine) and the garden irrigation with rainwater we offer you different tank systems, according to your requirements.

    Water conservation program for the garden

    The long-term weather forecast suggests that the weather is becoming warmer and drier. In the summer months there is less rain, so during this season the demand for watering the garden is rising. What could be better than to collect free rainwater for irrigation to use on dry days. Soft rainwater - your plants like this the most. Water your flowers in your garden with free rainwater from an outside tap using a WRS-USA Rainwater Harvesting System

  • Rainwater for domestic use

    How do I have to prepare?

    For a domestic house and garden system you will require a dedicated plumbing circuit to the toilet, washing machine and outside tap(s). This is most cost effective when a system is installed in a new build or major renovation. For an existing property, it may be more feasible to have a garden only system for plant watering and car washing which could, in the future be upgraded to a house system if required.

    How it works

    Rainwater from your roof is diverted into the underground storage tank, where it is filtered, kept cool and dark for optimum quality. On demand, the water is pumped directly to your WC’s washing machine and outside tap, or to a header tank, which in turn feeds your appliances. If the rainwater storage tank runs dry, depending on your individual system, a small amount of water will be “topped up” into the underground tank, or the header tank supply will be switched to mains water to ensure a constant flow of water to your appliances. The system will use rainwater again the next time the storage tank has sufficient water.

    House System with header tank

    Indirect System with back up into the header tank. Here Rainwater is pumped to the header tank which feeds the toilet and washing machine by gravity. The mains back up supplies the header tank, an auto flush system ensures water in the tank does not stay there for too long, and the pump only has to run once the header tank is empty, saving on electricity.

  • Retention Systems and Use of Rainwater

    Usage: With increasing risks of flooding, many communities are looking for ways to control the rate of water discharged into the sewer network during periods of heavy rainfall. The Retention tank addresses this issue. This not only offers rainwater storage for reuse, but also a buffer volume which can be set at any level to control the release of water into the network. The Buffer Volume will empty over time leaving space for the next heavy downpour.

    Function: The Tank has 2 sections. The lower portion is used as rainwater storage which is available for reuse in the garden or home. The upper portion is a buffer space. The floating throttle valve always stays at the same depth below the top of the water. Therefore water released from the buffer volume remains at a constant rate. The throttle valve can be pre-set at the desired flow rate and the position of the outlet pipe can be manufactured to the user’s specification to allow more or less buffer space as needed.

  • Seepage pumping shaft

    The pumping system is the solution to a rainwater underground tank that has excess water seeping to the surface. The overflowing water from the underground tank and ground water drainage is collected in the pump station, and from there pumped up to a soakaway. If the pumping station is empty, the pump switches off and waits until a certain fill level is reached again allowing enough time in which the water can seep away. Waterlogging is avoided, the soil remains biologically active.

    Pumping station - the benefits:

    • Easy to install and pump water where ground conditions don’t allow a traditional soakaway • Flow through the living soil layers, thereby biological purification of water • Low maintenance costs • Corrosion-resistant, extremely durable submersible pressure pump, automatic control via float switch • Simple and compact mounting due to low weight and ready to plug in pre-mounted pump

  • Rainwater Filters

    Can rainwater be made safe to drink? Yes. How safe? As safe as your well or tap water. How do you make it safe for indoor use? By filtering and purifying it.

    Pre Filter MAXI Plus Description: An excellent filter with many advantages. Maxi Plus can be inserted into existing pipes very easily, because the inflow and the outflow are on one level. The cleaning occures by a setting down and filtering process with 0,5 mm mesh width. The result is cystal clear and pure rainwater for the utilisation in house and garden.

    Pre Filter MAXI The filter basket prevents dirt particles from entering the rainwater to the tank. The result is clear and clean rainwater for the utilisation in house and garden. The filter basket is provided with a handy lift-out device

    Economical, efficient and environmentally friendly The sharp rise in water charges has led to more and more businesses, schools, etc. using rainwater harvesting equipment. Often these businesses have a large rainfall catchment and a high water demand, the many benefits of rainwater harvesting are obvious and financially lucrative.

  • Water - our most valuable resource

    What you should know The cost for City water has increased significantly more than other energy costs. This is likely to continue in the future. To provide clean mains water takes significant energy and with this, higher costs. So what makes more sense than a worthwhile single-investment using rainwater for up to half of your future water needs.

    Each of us uses on an average 138 litres of water day per day. This is more than 200,000 litres per year for a 4 person household. Halve your City water consumption by using rainwater.

    Good reasons to use rainwater • You save money by using less City water • You become more independent from the water suppliers and price increases • Soft rainwater with little lime is especially good for your plants • You contribute actively to the environment protection and conserve our valuable mains water stocks • You avoid costs of the unused rainwater being sent to the mains network • The drainage is relieved because the rainwater is collected at source for re-use and is not sent directly to the mains, this can help reduce local flooding
