Rain Harvesters' CASE HISTORIES and REVIEWS

A kind comment from a recent customer.. "Initially we liked the website video which explained your product, then yours was one of the only websites which gave an offer price for the full kits online so we had an idea of cost from the beginning. A couple of calls later and we had a mutually convenient delivery time for our kit. It arrived on time, all in order with full instructions. The tank is beautifully made and fit together easily. Great product and great service. I would certainly recommend your Graf tanks/kits and service to potential customers." More Case Histories here

Flat Tanks installed in Garden This rainwater harvesting installation is a retrofit and there was no intention to pipe up all the toilets and the washing machine, so it was decided to install a garden system, i.e. tanks without mains water backup. Therefore the water in the tanks can only be rain..	London Detached Rainwater System Their small detached house in North West London has enough roof to collect useful quantities of water and they have already shown that they are saving money	Garden Centre Yalden A GRAF Carat 2700 litre tank was installed to provide low cost watering of valuable stock. Big roof yields exceptional collection. Read more about this commercial application

More about Rainwater Harvesting

A great way to start would be to look at our Where to Start page - it will help with some of the decisions like.. would you like to locate your system above ground or below ground? Just for the garden or use for home and garden? Direct Feed (rainwater pumped directly to the point of use) or Gravity Feed (supply from a header tank at even and equalised pressure)? Whatever your needs, we have the equipment to deliver filtered, fresh, cool (if underground) rainwater to use where treated tap water would be a waste.

New on the block are the shallow dig tank systems. If you can't get digging machines onto your site or the groundwork will not allow deep excavation, our flat tanks or shallow dig tanks are the answer.

Need a powerful submersible rainwater harvesting pump? We now distribute the new HydroForce™ 800 watt pump - its a pressure sensitive 3.5 bar 240v pump for above and below ground applications. Read more about this UK manufactured and engineered rain water pump.

We have stocks of HDPE High density Polyethylene Rainwater Pipe in 25mm and 32mm bore sizes. Black and Green HDPE rainwater pipe is recommended for use in rainwater systems by the largest water and wastewater company in England and Wales.

We'll give you all the support we can in choosing the right equipment... we specialise in larger tanks and complete rainwater harvesting systems because our clients want to be able to use rainwater all year round. And we keep our prices way, way low. Most of our tanks and accessories come from Germany where rainwater harvesting has been well-established for many years. The components are produced to extreme tolerances are thoroughly tried and tested. Read a simple guide to rainwater harvesting here. 

"Easy Installation. We installed one of your Graf tanks near Bristol and it went together beautifully. Assembly and installation, including fitting the filter and pipes to the head of the tank were easy. The one piece main seal slips in like it lived there. These tanks make the competition look behind the times." Mr Paul Stoate, Devon. More Case Histories here

Another kind comment from a recent customer.."We have been able to install our rainwater harvesting in our London terrace home with no professional help at all. For Jay and me, two people who have got limited DIY skills, this has been achievable. When it comes to electricians, plumbers, plasterers, I’m going to hand that on to somebody else. But I’m really, really pleased that both of us, Jay and I, have dug this hole, we’ve had the confidence knowing that what we’re doing here is right. We can do the work now, then for years and years to come this will be free water every time we flush the toilet, every time we wash our clothes, we know that we can look skywards and we’ll say “Thanks. You know; free water! Great." I’m over the moon”  More on case histories.

Using rainwater in the garden

Lots of us already use rainwater from small waterbutts or waterbarrels for our garden watering. But rain collection in a 200 litre butt will not give much drought protection. We offer you bigger tanks at lower prices. We also offer a range of tanks adaptable to different locations: modular wall tanks that fit neatly against the house, large tanks that can be located away from the roof filling it and installed either above or below ground. Our range of accessories makes using rain water storage easier and more pleasurable. Filters and Syphons and help stop stored water turning brackish and sediment accumulating in tank bases and in taps and hoses. Pumps make distribution from the tank easier by maintaining good pressure.

Do you have a patio or some decking? An F-Line Flat Tank could fit under your patio or decking  and cut the cost of installation dramatically. The Flat Tank concept is perfect for light excavation in smaller gardens with limited access for larger machinery. If you have a spade and can dig a hole, this DIY tank is ideal, especially when hooked up to a pump and filter in one of our systems. Have a look at some shallow dig or flat tank garden systems here.

"The bigger the tank the more you will gain from using rainwater.."

Using rainwater in the house

With a little extra investment, rainwater can be used inside to feed WCs and washing  machines. Installing a domestic system is more straightforward in a new-build home, but with some alterations to down-pipes and interior plumbing, a system can be added to existing houses. Water tanks of 2000 to 7000 litres are needed for feeding the home and we can supply you with the accessories needed, including pumps, super filters and a mains switchover panel which transfer the rainwater supply system to the mains if the tank runs out. We now have a wealth of information about managing rainwater in the home and articles about rainwater in multi-home developments.

Rainwater Harvesting Ltd is the home of the WRAS approved Rain Director®, the rainwater management control system that will help you feed cleaner rainwater to toilets and washing machines at constant pressure. The Rain Director® saves you money on energy and reduces the wear and tear on your pump.

Nigel Jenkins of Devon wrote to us saying ."You may or may not be aware but the water charges down here in the South West are some the highest in the Country. A typical 3 bed terrace house in Plymouth is charged approximately £900 per year in water rates (I own a number of terraces and they all cost about the same). This can drop if a water meter is used. However my own cottage is on a water meter, only two of us live there and the water charges are in the region of £700 per year." On this basis you would save £350 to £450 a year and amortise the equipment cost of a 2700 litre tank and complete system at £1850 (including tax and delivery) in 4 or 5 years!"

Hosepipe Bans.
Hosepipe bans are the gardener's nightmare and new proposals would give water companies the right to prohibit use of hosepipes during a water shortage for other outdoor cleaning purposes such as washing boats, patios, drives and windows; cleaning stables, outbuildings and greenhouses; and also for filling swimming pools, ornamental ponds and hot tubs. With unexpected dry spells followed by weeks of rain it is very hard to judge supply - so a personal water supply can help get you through the highs and lows even if the water companies can't. Environmental protection is vital and saving water is high on the list.

"Just wanted to let you know that the tank arrived this morning. Your driver was a real credit to your company, polite, cheerful and very helpful. I forgot to ask his name in the confusion of getting the tank into the garden, but please pass on my thanks once more to him." Simon [It was Des] More Case Histories here
