Garden Rainwater harvesting

The Rain King 1000

With the onset of Summer and the news that we are facing water restrictions, not to mention brown grass! At Freerain Ltd we have been busy sending out one of our best selling products, The Rain King 1000. This is a basic, very DIY friendly due to the ease of the tank being hand-dig-able, but still a large enough volume to make a real difference compared to normal above ground water butts.
As part of the packaged the Rain King 1000, includes a 1,000 litre underground polyethylene storage tank, a downpipe filter and a stainless steel submersible pump. All this delivered on a pallet for only £869 (as June 2011). See garden rainwater harvesting for more information.

There are also storage tanks from 1800 right up to 10,000 litres with internal pre-tank filters for gardeners wanting even more water. These are also pumped systems and manufactured in the UK!!!

Above ground rainwater harvesting

We also appreciate that it is not always possible to bury a rainwater harvesting tank and so we also have a wall tank system, these are 800 litres each, so around 4 times the capacity of the traditional water butt and can be linked together to make really serious sized systems. Each system includes a tank, down pipe filter/diverter, a sight gauge and a pump. All the necessary inter-connecting pipes are included. See above ground rainwater harvesting for more information and current pricing.

We have received an so many enquiries from people who have been using water butts for a long time, and now realise that over the last few years, these are simply not large enough to last through significant periods of low rainfall. Also, when it is dry and hot, often this can be broken up by a heavy thunderstorm. We really need to intercept this and store it. Meaning that unless a decent amount of capacity is available, this opportunity will be lost.

Warmest April on record 2011

It has been reported this week that April 2011 (UK) was the warmest on record and figures out today shows that rainfall in most parts of UK were very low indeed. The south coast have received about 3-5% rainfall that they would have expected for April. Parts of Scotland were the exceptions with slightly above average, but only by a few percentage points.

The BBC are reporting that following a dry March as well, in terms of agriculture we could see food prices rise due to either lower yields and/or due to the cost associated with irrigation. This of course raise many questions, questions that are really beyond this post and indeed this blog.

We at Freerain have seen a massive increase in the number of potential customers looking for solutions to their water shortage issues. These range from the typical home gardener, who's traditional water butts ran out during the first weekend of April (if they lasted into April), to the small-holding needing a regular supply in larger quantities. We have also received enquiries from the leisure industry, for example pine lodge parks, these are often in slightly remote areas and need water mainly for irrigating their plants and in some cases washing down of the lodges themselves.

One question which is often aimed at rainwater harvesting is "if doesn't rain, what's the point of putting a tank in?" Which if you think about that, it is true. However, these dry spells (or actual drought conditions) are not rare events. Virtually every year we get similar stories in the news about lack of rainfall, coupled with increased demand (especially in the South East). Water shortages are not going away. So our customers are right to look to finding a solution not necessarily for their immediate problem, but for the next dry event.

In our office, we have been using rainwater harvesting to provide WC flushing and the occasional car washing function for about 12 years now and in that time we have seen many very dry spells. These are often combined with heavy storms in the middle of the hottest weather. These high rainfall events, fill the tank very quickly, which gives the office a supply for the next three weeks.

As mentioned above, garden watering is a hot topic (pardon the pun!) and it is much easier to install a system for gardening. This is because the is no requirement to change the household plumbing. Also, often the whole roof is not required meaning that the drainage also doesn't require substantial alterations. Our most popular systems are the Rain King garden systems. With the easiest of all and the most cost effective being the Rain King 1000.

Water shortages again in the news

Well it's been the driest March for about 40 years for most parts of the UK. Already here we are in the 3rd week of April (2011 and there are stories in the news appearing about the water levels in our reservoirs.

The BBC has reported earlier this week that some of the reservoirs are currently at around 80% of the expected levels for this time of the year. But didn't we have a decent amount of rainfall over the winter (including the several bouts of snowfall)? So one dry month and the country seems to start running out of water.

Does this mean that we are in fact living beyond our means for water, especially with a drier climate predicted and an ever-increasing population?

This hightlights the need for a water strategy and one which embraces all available techniques, from water conservation right throught to localised capture/collection. Obviously we at Freerain are very focused on rainwater harvesting and we have seen from our own monitoring that a typical household can reduce their mains water demand by 50%. But also there is a need for education at various key levels to ensure that water is used carefully.

There has been some debate over the years surrounding the carbon cost of rainwater harvesting, but it must be stressed that a small amount of carbon is more than worthwhile to keep the taps flowing. Again, rainwater harvesting must be used together with various other techniques as part of an all round effort.

At Freerain we have recently launched a new range of UK manufactured rainwater harvesting tanks to further reduce the environmental impact of similar German imported tanks. These tanks can be used in domestic and smaller commercial applications. They start from 1,800 litres right through to 10,000 litres, all single piece and all have a very low profile. Being made from polyethylene and designed to be installed in very high water tables, they can be installed without concrete bases, backfills or surrounds. Domestic rainwater harvesting tanks
