Drinking water

Replaceable by rainwater

Harmer Kessel Rainwater Management Systems offer

supremely sustainable and economic solutions to the

re-use of rainwater for non-drinking applications.

Never Short of WaterThe high cost of providing purified drinkingwater is well known, but much of thewater used by homes and industry doesnot require such a high level of purity – eg,toilet flushing, clothes and car washing,and garden watering.

Natural rainwater can be collected,filtered and distributed for many uses,bringing major environmental andeconomic benefits – as well as addingvalue to a property.

Harmer Kessel Rainwater ManagementSystems will never leave youinconvenienced by a shortage of water.Sensors detect when storage tanks arenearly empty and refill with mains water.When a sufficient quantity of water hasbuilt up, the switch reverts to naturalrainwater mode.

Almost 50% of domestic water consumptioncan be replaced by using Harmer KesselRainwater Management Systems.

The System Choices

Garden Use

Harmer Kessel Rainwater ManagementSystems are a simple solution for there-use of water for outdoor cleaning,watering and bathing. Rainwater filteredand stored underground in an Aqabase®

tank can be automatically turned on atwill to provide all external water needs.

Domestic Use

The Aqabull® and Aqadive® RainwaterManagement Systems are designed forinstallation in single family or multi-family homes. Large applications – eg,blocks of flats and industrial buildings,can be handled using our twin pump unitsor custom designed systems.

Aqabull® pumping systems are installedat ground floor or basement, or in anoutdoor, protected enclosure.

Aqadive® pumping systems are installedat ground floor above the backwaterlevel, or, as with Aqabull®, in an outdoor,protected enclosure.


Effective, Economic, Sustainable

The principle is elegantly simple. Rainwater falling on a roof, is collected, filtered, stored

and distributed around a home or other types of building to fulfil a host of non-drinking

water uses - eg, bathing, wc flushing, car washing, clothes washing, garden watering, etc.

Rainwater falls on theroof and is collectedby the guttering andchannelled into therainwater downpipe.

The rainwater is divertedthrough a filter into anunderground rainwaterstorage tank.

A pumping unit controlsthe supply of storedwater. When anappliance or fitting isswitched on, this isdetected by a pressureswitch, which activates apump drawing water outof the storage tank towherever it is requiredfor use. When theappliance or fitting isswitched off the pumpceases operation after ashort delay.

An overflow pipe allowsexcess stored water toescape to a soakaway orsurface water drain.

Installation hints for Harmer Kessel Aqadive® Rainwater Pumping Units

The mains refill port inside the Aqadive® unit must be installed at least 15cm above thebackwater level.

The piping and cables for an Aqadive® or an Aqabull® unit are to be placed inside an emptypipe (DN 150) which is run with a continuous negative slope and in a frost free area fromthe Aqadive® or Aqabull® unit to the rainwater storage tank.

If this empty pipe enters the home or building below the backwater level it is important toprotect this entrance with a Harmer Kessel DN 150 backwater sealing pipe insert - Ref 85412(for Aqadive®), Ref 85413 (for Aqabull®).

Product Advantages

Recyclable material

Polyethylene can be fully recycled andreused for the production of high qualityproducts.

Durable

Polyethylene guarantees a high durabilityagainst dents, cracks or breaks in thematerial.

Load Class B manhole covers -12.5 tonnes load class

The Harmer Kessel manhole covers forAqabase® Komfort storage tanks aredesigned for Class B (12.5 tonnes) use.This enables the storage tanks to beplaced under driveways or parking areaswhere passenger vehicle and lightcommercial traffic are present.

Adjustable cover

Harmer Kessel System 400 RainwaterFilters for underground installation andthe Harmer Kessel Aqabase® KomfortRainwater storage tanks are suppliedwith fully adjustable covers in variousload classes. These covers are verticallyadjustable, twistable and tiltable upto 5 degrees to allow for surfacevariations and slopes. These coverswill automatically compensate forsettlement or heaving of the soil.

Transport friendly

All components of Harmer Kessel Rainwater Management Systems areproduced from high quality, virgin polyethylene, which is impactresistant, durable and lightweight. Pumping units and filters are easilytransported by hand while the storage tanks can be shipped withstandard trucks because of their light weight/heavy dutyconstruction. On site, the separators can also be easily movedwith fork lifts using the integrated fork lift grips.


Additional Information

Emergency Overflow

All Aqabul® Rainwater PumpingSystems are equipped with anemergency overflow and an integratedodour trap.

Automatic filter backwashing

All Harmer Kessel System 400 Rainwater Filters are available with or without thebackwashing unit. The backwashing unit can also be installed at a later date.

Filter Extension Handle

Harmer Kessel System 400 Rainwater Filtersfor underground installation can be installed asdeep as 1330mm below finished ground level.In instances where the filter is installed nearthis depth, a special filter insert with anextended handle is available for ease inremoval or replacement of the filter forinspection and maintenance purposes.

Aqabull® anchoring system for high groundwater areas

Where the Harmer Kessel Aqabase® storage tank is installedin areas of high groundwater, it is important that the tank befirmly anchored. This is accomplished by securing the basewith steel anchor bars in a 300mm tall footing or foundationas seen in the illustration.

Please Note: The anchoring system assists when only the lower portionof the tank is expected to encounter groundwater. In cases where asignificant portion of the tank is expected to be under groundwater, pleaseconsult Alumasc prior to installation.


Technical Information

Sample calculation

Single family house,roof area 170 m2.Run-off Coefficient = 1.0

Household with 4 inhabitants

Garden area: 300 m2 of which100 m2 will require watering

The collected rainwater will beused for toilet flushing, gardenwatering, clothes washing andhousehold/outdoor cleaning.

Step 1

Calculate the estimated yearly rainfall collection total.

Step 2

Calculate theannual service waterrequirement (seemethod opposite):

24 x 4 x 365 = 35,040

10 x 4 x 365 = 14,600

2 x4 x 365 = 2,920

plus

60 x 100 = 6,000

58,560 litres

Step 3

More rainwater is collected annually than is required (122,400 litres > 58,560 litres)

The calculated required storage volume is 3,369 litres (see formula opposite)

The optimal rainwater storage tank volume is a 4,500 litre tank

Formula

Horizontal collection area x roof runoff coefficient* x precipitation inlit/m2/year** x filter collection factor***

* See included table

** Consult local rainfall historical data

*** If maintained and cleaned properly the Harmer Kessel System 400 Rainwater Filtercan achieve a filter collection factor of 0.96

The dimensions of rainwater storage tanks arelargely determined by two factors:�� The rainwater yield

(Rainwater collection area, loss factors and local rainfall figures)

�� The amount of service water required

(Type and number of consumption points)For economic reasons, a balance has to be struck between the amountof rainwater available and the amount of service water needed. Theavailable rainwater should be utilised and the amount of drinkingwater used to supplement it minimised.

When calculating the amount of rainwater available, use the annualrainfall figures in mm or litre/m2. Ask your local weather centre or consultthe Internet.

When downpipe filters and fine fluidised bed filters or inlet filters areused, the manufacturer’s instructions on the volume flow of rainwaterthat can be used should be followed.

The theoretically storable quantity of rainwater can be calculated asfollows:

The run-off coefficient is used to allow for losses due to the position,gradient, orientation and type of material of the collection surface.

Type of collection surface Run-off coefficient Ψ

Roof surface with a slope > 3 degrees 1.0

Roof surface with a slope <= 3 degrees 0.8

Gravel-covered roofs 0.5

Intensively cultivated roof areas 0.3

Extensively cultivated roof areas with soil depth over 100mm 0.3

Courtyards paved with concrete blocks and areas covered with slabs 0.7

Rainwater yield (litres/year) =∑ A (m2) x Ψ x NH (l/m2) x ηFil

A: Collection area Ψ: Run-off coefficient NH: Rainfall ηFil: Filter efficiency.

Calculations and system sizing are available to DIN 1986 and BS 8515 fromthe Alumasc Technical Helpline 01744 648400

* Storage volume is multiplied by 21 as a safety factor (this 21 day or 3 week period is expected to be the longest duration without rainfall)

TOTAL service water/annual requirement = Annual service water requirement 1 + Annual service water requirement 2 litres/year

Proven Project Track Record

St Pancras Station, LondonThe £800million extension andrefurbishment of St Pancras Stationdemanded the faithful restoration of SirGeorge Gilbert Scott’s neo-gothic facadesand detailing. English Heritage insistedthat replacement rainwater goods beperfect reflections of the original castiron work.

Alumasc met this challenge with ApexHeritage Cast Iron, making bespokemoulds to create replacementdownpipes, gutters and rainwater headsthat capture perfectly the authenticquality of the beautiful Victorianoriginals.

New Providence Wharf andOntario Tower, LondonA dramatic, futuristic addition toLondon’s skyline, this mixed-use urbanvillage of apartments, offices, retail andleisure spaces and hotel tower, isinterwoven with a complex of greenroofs, water features (including a canal)and podiums. To meet the technical andaesthetic demands of this diverseconstruction project, three premiumAlumasc products were used: ZinCobiodiverse and intensive green roofs,Hydrotech structural waterproofing andDerbigum waterproofing membrane.

Lancashire SchoolsAlumasc provided all the components and technological expertise needed toachieve the advanced waveform metalroof which gives this new sports hall (oneof three, serving schools in the area) itsdistinctive appearance. The dramaticcurvature has been quickly andeconomically achieved by using theArmaseam ‘zip-up’ aluminium roofingsystem (also available in copper, stainlesssteel or zinc) with Alumasc rainwatergoods and Skyline fascias and soffits.
