FAQ Rain Activ
Q: What is Storm Attenuation
A: Storm attenuation is the collection and controlled release of storm water in order to prevent flooding from overwhelmed storm drains.
Q: How does Rain Activ work.
A: Rain Activ is a tank and special filter that both stores rainwater for Rainwater Harvesting as well as allowing controlled release when the tank passes a specified level.
Q: Why is Rain Activ different from others on the market?
A: Rain Activ is a new an innovative addition to the SuDS market because;
- Rainwater is used, therefore saving valuable mains water. Unlike storm crates and ponds which put the water to waste.
- Output levels are assessed and documented for your site, with figures provided ready to submit to planning authorities.
- The system is calibrated especially for the site, instead of a one size fits all͛ system.
Q: How long do attenuation calculations take?
A: Generally we aim to provide calculations within 5 working days.
Q: I’d prefer not to use the system for Rainwater Harvesting- will Rain Activ work without?
A: Yes, we would either alter the system so it works on 100% attenuation, or just connect to one garden/outside tap.
Q: Can Rain Activ replace all SuDS requirements.
A: Rain Activ is for roof water only, so should be thought of as a vital addition to your SuDS plan. In some cases showing you are dealing with the roof water effectively may be enough to meet planning requirements.
Q: Where can I purchase a Rain Activ system?
A: Systems are available from our retail site- Rainwaterharvesting.co.uk
Q: What is typical dispatch time?
A: Every Rain Activ is built bespoke to requirement so a small amount of work has tobe done on each. All components are ex stock so typically 3-4 working days.
FAQ rainwater harvesting?
Q: What is Rainwater Harvesting
A: Rainwater harvesting systems collect and store Rainwater that would otherwise have been put to waste either to drains or soakaways.
Rainwater is then reused in non potable applications. This reduces water bills, saves money and makes a home more sustainable.
Q: What can you use rainwater for?
A: Rainwater can be used for can non potable application. This includes;
- Toilets (around 35% water use)
- Washing Machines (around 15% water use)
- Garden/Outside Use (around 5%, yet this figure can grow greatly for keen gardeners)
Q: Why should I use rainwater?
A: Studies show each person in the UK uses around 150 litres of mains water per day. With only 50% of this water actually needing to be of drinking quality, the carbon intensive process of treating and pumping the water isclearly a waste of resource.
Q: Is rainwater better than drinking water for non potable use?
A: Absolutely, it out performs mains water for most application and is completely free!
- Due to Rainwater’s softness, Toilets and washing machines require less chemicals and detergents (lots of your washing powder is used to break down the ions in the water) and will be less prone to breakdown.
- Plants do not like the chemicals in mains water-studies show your plants will grow faster with Rain.
- Koi are very sensitive to the chemicals in mains water. Rain is a much better choice due to its acidity.
- Car and window washing smear free (the streaks and dots are limescale).
Q: Can I used harvested water during a hosepipe ban?
A: Yes, its your water, use as you wish.
Q: How much will I save using rainwater harvesting?
A: Depending on your useage and location a considerable amount. For a full domestic system, you will save around 50% on your current metered bill. If you have large water requirements, the savings can be even greater.
Customers have reported savings of £500-600 per year.
Q: Is Rainwater safe? Does it go yellow? Is there a legionella risk?
A: YES, NO and defiantly NO. A properly designed system filters the water heavily the stores it underground where it stays at a constant, cool, temperature and in the dark. Together, this makes bacterial action virtually impossible. Collected Rainwater stays odourless, clear and clean in any correctly installed and maintained system. Legionella only occurs with water temperatures above 15 degrees and direct light. Underground tanks stay at roughly 4 degrees year round and with no access to light.
Q: Does Rainwater Harvesting act as part of a SuDS system?
A: Yes- systems slow the rate of rainfall rushing to the storm drains. This is especially the case of our Rain Activ systems.
Q: What if I’m off grid? Can I use rainwater for potable purposes such as drinking and washing?
A: Water treated with UV filtration to make it drinking quality, yet this tends to only economically viable where occupants have no mains water source.
