STORMWATER MANAGEMENT SYSTEMSGeneral introduction ■ Stormwater Management Systems
4
Development of sites results in a large
proportion of area being covered by
impermeable surfaces such as roofs, car
parks and roads. Surface water run-off
therefore increases up to 80%. Regulators
(Environment Agency, Scottish Environment
Protection Agency and local authorities) are
promoting the use of Sustainable Drainage
Systems (SUDS) that control run-off to that
of a greenfield site (around 20%).
Wavin Stormwater Management Systems
have been developed to provide a method
of source control in two ways:
By providing temporary storage for
excess flows and limiting outflow to
streams and rivers.
By providing soakaways to infiltrate
stormwater back into the ground.
The modular nature of Wavin Stormwater
The AquaCell® Systems:
The AquaCell systems are a fully tried and
tested modular technique for managing
excessive rainfall by creating an
underground structure as either a
temporary storage tank or a soakaway:
AquaCell (blue unit)
for trafficked locations
AquaCell Lite (green unit)
for landscaped and non-trafficked sites
AquaCell
AquaCell Lite
Management Systems means that they
can be tailored to suit the specific
requirements of each site. They can be
used to provide temporary storage,
attenuation and infiltration capacity for run-
off for all sizes and types of site: from
individual houses up to the largest
commercial developments.
General Introduction
Stormwater Management Systems
Box systems – select with care
Rising rainfall levels, and increased
focus on SUDS compliance, have led
to a sharp increase in the use of modular
box systems to create underground
structures for infiltration or temporary
storage of stormwater.
However, not all currently available
systems have the proven performance
characteristics necessary for the wide
range of complex underground
geocellular applications (see page 11).
With OSMA AquaCell systems,
however, the required strength and
hydraulic capabilities have been verified
by independent testing.

OSMA AquaCell StormwaterManagement System
Comprises individual infiltration modules
assembled together to form underground
structures which can either be used for
stormwater storage or as an alternative to
domestic soakaways.
Heavy storms and major cloudbursts are
becoming more frequent, resulting in ever
increasing volumes of stormwater flowing
into conventional drainage systems and
water courses. When the capacities of these
systems are exceeded the consequences
can be dramatic and damaging.
Stormwater must be controlled; either by
limiting the outflow and providing
temporary storage or where the ground
conditions are suitable, providing
soakaways for the stormwater to infiltrate
back into the surrounding ground.
This has the added benefit of recharging
the local groundwater.
Both options can be achieved using either
OSMA AquaCell or OSMA AquaCell Lite
depending on the application.

STORMWATER MANAGEMENT SYSTEMSAquaCell Systems Overview ■ How they work
6
Both OSMA AquaCell and AquaCell Lite
units are modular in shape (1.0m x 0.5m
x 0.4m), have a 95% void and a capacity
of 190 litres per unit. The lightweight,
polypropylene units are easy to handle
and install. Original AquaCell (blue unit)
weigh 9kg each and AquaCell Lite (green
unit) weigh 7kg each. Individual units are
securely linked together using special
clips and shear connectors and can be
assembled quickly on site into whatever
configuration suits each specific location.
AquaCell geocellular systems also allow
‘brick-bonding’, which can give extra
stability, without the need for additional
connector pieces.
Wrapped for infiltration or storage
The complete assembly is wrapped in
either geotextile or a geomembrane
(wrapped with a protective fleece).
For pervious soils, the geotextile allows
infiltration of stormwater into the
Stormwater exceeding the capacity of the
conventional drainage system is
attenuated by the control manhole and
channelled into the AquaCell unit
assembly. The internal structure of each
unit is designed to bring surging water
under control and hold it in temporary
storage. If the wrap that envelopes the unit
assembly is impermeable the water will
remain in the unit assembly until such a
time as it can flow back into the control
chamber and discharge through the
outflow control. However if the wrap is
permeable, the temporarily stored water
may be released into the surrounding
ground; soil conditions permitting. By
controlling the stormwater at source and
recharging the local groundwater it not
only eases the pressure on conventional
drainage systems but benefits the local
environment as well.
surrounding ground. Where the ground is
impervious (e.g. clay) or where infiltration
is not desirable, the geomembrane
encapsulated assembly holds stormwater
in temporary storage until local drainage
flows can accept it for normal disposal.
Benefiting the communityand the environment
AquaCell systems contribute the
following benefits:
Significantly reduced flooding risk
Controlled, reduced-volume release of
stormwater into existing sewer
systems or watercourses
Recharging of local groundwater
(if infiltration/soakaway application)
Aerobic purification to improve water
run-off quality
Sustainable, cost effective
management of the water
environment
Supporting SUDS – and facilitating planning approval
The proven qualities and performance of
the AquaCell system not only support the
achievement of SUDS, they can also help
reinforce and enhance planning
applications, and enable development to
proceed.
Control Manhole
This manhole is designed to limit the
downstream discharge using an outflow
control and if necessary redirect the excess
stormwater via an overflow control into the
AquaCell units.
Manifold Configuration
A junctioned pipework assembly providing
a controlled multiple feed of stormwater into
the AquaCell Units. The configuration is
tailored to suit the capacity required upon
entry into the AquaCell Unit assembly and
upon discharging to the control manhole.

Installation and cover depth
After deciding which AquaCell system
is correct for the project location (using the
System Selector – left), see the
following table for the recommended
maximum installation depths and
minimum cover depths.
(1) For specific advice on cover depths for heavier loadings/HGV applications, contact WavinTechnical Design on 01249 766655
(2) 0.3m is minimum depth for AquaCell Lite, although0.5m cover is recommended to prevent accidentaldamage. If construction plant is to be used on siteduring installation, please see Installation guidance onpage 11
(3) Allowable maximum depth to base of bottom layer ofunits is dependent on soil type, angle of shearingresistance, loadings, and groundwater level. In poorground conditions a shallower depth may apply.
Hydraulic and structural design
Both AquaCell and AquaCell Lite have
identical dimensions: 1m x 0.5m x 0.4m,
with a nominal void ratio of 95%. Hydraulic
calculations are accordingly the same for
both systems. Structural design requires
careful consideration of loading factors
specific to each location.
(see Geocellular structures: important
design considerations on page 11).

STORMWATER MANAGEMENT SYSTEMS Product & Installation Guide 2005
AquaCell Lite: additionalinstallation guidance
Due to the special physical properties of
AquaCell Lite, certain precautions are
recommended on site to prevent damage
to the units through excess loading.
Manual assembly
Whilst assembling the tank, it may be
necessary to walk on top of previously laid
units, care should be taken not to damage
the edges of the units.
Construction traffic on site
If construction plant (e.g. excavators
or loaders) are likely to run over the
installation:
MINIMUM protective cover: 500mm
well-compacted granular material
Excavators MUST NOT exceed
14 tonnes. Compaction plant not to
exceed 2,300kg per metre width
HGVs MUST NOT be allowed to run
over installed AquaCell Lite units
Backfilling
When backfilling AquaCell Lite installations:
Machines placing the material must be
located OFF the units
Only light compaction should be applied
to the material
If Type 1 sub-base (or similar) material over
AquaCell Lite units requires compaction:
First layer should be 300mm thick
before any compaction
NO vibratory mechanism should be
used for compacting this first layer
MAXIMUM roller size: 2,300kg per metre
width
Ancillaries and Adaptors
All ancillaries and adaptors available for use
with AquaCell can be used with the new
AquaCell Lite system, except the 225mm
Flange Adaptor (6LB106). The 150mm
Flange Adaptor (6LB104) should only be
used when constructing an air vent, on the
top surface of the unit.
Geocellular structures:important design considerations (see Note*)
To guarantee structural integrity, any
underground structure must be strong
enough to support the loads to which
it will be subjected without any
unacceptable deflection.
The correct choice of geocellular box
must have appropriate proven top
(vertical) and side (lateral) load bearing
capacity and deflection characteristics
to suit site conditions.
The five key site considerations to be
noted when designing a geocellular box
system are:
1 Depth of cover (see page 10)
2 Soil type
3 Surface finishing
4 Presence of groundwater
5 Type of traffic/loading
*Note: The combination of these factors effectivelymeans that the required characteristics of a geocellularsystem to be installed under a trafficked location (for example) will be very different from that under a landscaped/low-loaded location.
EXAMPLE A: Car park with occasional lorry traffic and0.6m cover depth. Typically requires minimum verticalstrength of 40 tonnes/m2
EXAMPLE B: Landscaped/non-trafficked location and0.3m cover depth. Typically requires minimum verticalstrength of 17.5 tonnes/m2
These factors have already been taken into consideration within the simple selection flow chart on page 10 for BOTH AquaCell systems.

slightly greater than that of the
AquaCell/AquaCell Lite units.
2. Lay 100mm bed of coarse sand or non
angular granular material, level and
compact.
3. Lay the geotextile* over the base and
up the sides of the trench.
4. Lay the AquaCell/AquaCell Lite units
parallel with each other. In multiple
layer applications, wherever possible,
continuous vertical joints should be
avoided. AquaCell units can be laid in
a ‘brick bonded’ formation (i.e. to
overlap the joints below). For single
layer applications use the AquaCell
Clips and for multi layers use the
AquaCell Clips and the AquaCell Shear
Connectors.
5. Fix the Adaptors to the AquaCell Units
as required and connect pipework.
6. In order to prevent silt from entering the
tank, clogging inlet pipework and
reducing storage capacity, it is
recommended that the OSMA Silt Trap
(6LB600) is installed prior to the inlet
pipework - see page 14 for installation
guidelines.
7. Wrap and overlap the geotextile
covering the entire AquaCell/AquaCell
Lite structure.
8. Lay 100mm of coarse sand or non
angular granular material between the
trench walls and the
AquaCell/AquaCell Lite structure and
compact.
9. Lay 100mm of coarse sand or non
angular granular material over the
geotextile and compact. Backfill with
stone free as-dug material.
10.Rainwater from roof areas may
discharge directly into the soakaway
but rainwater from carparks must
discharge through a catchpit manhole
or a petrol interceptor.
* The geotextile should be selected according tospecific site conditions, however, typically a 300gmaterial will be suitable. Specialist advice shouldbe sought if surrounding soil characteristics exhibita high degree of fines/low infiltration capacityand/or there is a high risk of damage from groundcontaminants.

STORMWATER MANAGEMENT SYSTEMSIntroduction to Garastor
24
Development of sites results in a large
proportion of area being covered by
impermeable surfaces such as roofs, car
parks and roads. Surface water run-off
therefore increases up to 80%. Building
Regulations and guidance now requires a
sustainable approach to development,
which minimises the effects of run-off to
that of a greenfield site (20%).
Developed in collaboration with Bryant
Homes, Garastor (polypropylene control
chamber) represents a house by house,
rather than a development wide
approach, to stormwater management.
Garastor controls the flow of water at
source by temporarily storing water under
a soft landscaped area using the AquaCell
system or in the void space under the
floor slab of a residential garage. It
eliminates the need for costly, space-
hungry, on-site communal water-storage
structures or ponds which enables better
use of developable land.
During high intensity rainfall, water from
the roof or hardstanding areas is diverted
via the Garastor control unit into the
storage void. As the storm subsides the
rainwater can be slowly released back
into the main drainage system.
Note: Garastor can be used as a flow control devicefor any AquaCell storage system, no greater than oneunit deep with a discharge of up to 1.4 l/s via the30mm release flow orifice.

STORMWATER MANAGEMENT SYSTEMSIntroduction to Garastor ■ Garastor System Overview
STORMWATER MANAGEMENT SYSTEMSGarastor System Overview
25
STORMWATER MANAGEMENT SYSTEMS Product & Installation Guide 2005
Garastor System
The Garastor unit is a polypropylene
chamber that connects to a water storage
reservoir. There are two versions of the
Garastor available both of which are
500mm in diameter, the 6SC500 version is
1m deep for garage installations (with a
300mm storage depth capacity) and the
6SC501 is 1.25m deep for use with
AquaCell* (with a 400mm storage depth
capacity). When Garastor is used in
conjunction with an AquaCell tank the
configuration of units must be no deeper
than 1 AquaCell unit.
If site conditions are such that a deeper
Garastor unit is required then the 500mm
Extension Kit (6SC205 – consisting of a
coupler and two ring seals) can be used in
conjunction with a shaft of 500mm Twinwall
cut to suit, to extend the Garastor unit.
* Depending on the application either AquaCell orAquaCell Lite may be used in conjunction with Garastor.For further details contact Wavin Technical Design.
HOW IT WORKS
Storm or surface water flows through two
110mm diameter incoming pipes. If the
flow is light to moderate, the water is
simply stored in the chamber before being
slowly released through a 30mm orifice.
However, if the inflow is heavy, excess
water in the chamber discharges through
a 150mm diameter pipe into the water
storage area (either the undercroft of a
garage or an AquaCell tank). The water is
temporarily stored until the water level
inside the chamber has dropped
sufficiently, and the water can flow out to
the drainage system via the 110mm
outflow pipe.
Inside the Garastor chamber there are
specially designed weir walls that ensure
that the hydraulics of the unit work to the
optimum levels.
KEY BENEFITS
No use of valuable, developable land.
Safer than open/above ground storage structures.
Caters for 1 in 150 year storm.
Spreads cost of water storage over the development period.
Maintenance free, with no moving parts or filters.
Run-off reverts to that of a greenfield site.

STORMWATER MANAGEMENT SYSTEMS Product & Installation Guide 2005
1. Place the Garastor Unit (6SC500 or
6SC501) on a minimum of 100mm
“as-dug” or granular material. Ensure
that the unit is as close to the garage
undercroft or AquaCell structure as
possible and in a suitable position to
allow pipework connection.
Note: It is important to ensure that the chamber is placed in alevel position and that the invert of the 150mm pipeconnection is level with the base of the concreteundercroft or the base of the AquaCell units.
2. Connect pipework in accordance with
standard pipe installation guidelines.
3. Surround the Garastor unit with
150mm of similar material to that used
for the bedding.
4. Fit relevant cover and frame according
to depth of unit: Up to and including
1.2m deep 4D943, deeper than 1.2m
6D931.
Note: When surrounded by a concrete plinth(150mm x 150mm) the cover can be used in situationswith a loading of upto 30Kn (3 tonnes) i.e. domesticdriveways.
5. Adequate ventilation must be
provided:
- to the garage undercroft using
either air bricks or rainwater
downpipes connected directly into
the storage area.
- to the AquaCell structure using an
air vent (NB. One air vent is
required per 7,500 square metres
of impermeable area to be
drained).

Notes: When using Garastor with the undercroft/voidof a garage, it is the responsibility of the designer toensure that the enhancement to the garageundercroft/void and drainage works comply withcurrent prevailing Building Regulations.
Also to prevent softening of the soils below thefoundations or loss of fines leading tosettlement, the void beneath the garage shouldbe lined as follows:
Underneath the concrete base of the voidarea there should be a 1200g polythenedamp proof membrane.Bitumastic paint should be applied to thewalls of the void area and to the undersideof the reinforced garage floor beams.
* Depending on the application either AquaCell orAquaCell Lite may be used in conjunction withGarastor. For further details contact Wavin TechnicalDesign.

Case studies
The sky’s the limit for WavinPlastics
THE CLIENT:
Birmingham Airport
THE PROBLEM:
To prevent flooding on a new long-stay
car park covered with paving, and help
the Airport to comply with its policy of
sustainable development.
THE SOLUTION:
Over 7,000 AquaCell infiltration modules
were installed on the site providing a
robust and long life infiltration base. A
permeable geotextile was the only other
component required to complete the
installations.
THE QUOTE:
“Wavin’s solution to stormwater
management combines practical and
operational benefits over the alternative
methods available to the developer. Its
system proved to be economically and
functionally favourable whilst providing
storage of over 1,300 cubic metres of
surface water run-off.”
AquaCell passes toughesttests during worst stormsfor 50 years
THE CLIENT:
Ilchester Cheese Company
THE PROBLEM:
Controlling flooding/water on a regularly
flooded area.
THE SOLUTION:
In order to control stormwater at the
Ilchester site, a system which comprised
of 1,352 AquaCell units was installed to
limit the outflow and provide temporary
storage.
THE QUOTE:
“What we have seen at the Cheese
Company over the past fortnight is
evidence of a highly successful system.
The surrounding area is completely
waterlogged with the river only half a mile
down the road. Our site is bone dry - any
risk of damaged land has been alleviated”.
Weathering the storm onBrownfield Land
THE CLIENT:
Graham & Brown Wallcovering
THE PROBLEM:
How to manage/control storm or flood
water on a low lying brownfield site,
adjacent to a river with a history of
flooding, and prevent the leaching of
contaminants into the high water table
from the site which used to be a power
station.
THE SOLUTION:
To collect stormwater from the
development in a trench surrounding the
new factory filled with 2,000 Wavin
AquaCell units clipped together,
encapsulated in a robust fully welded
hydrocarbon resistant geomembrane,
which in turn was wrapped in a non-
woven needle-punched geotextile.
THE QUOTE:
“The 95% void capacity of Wavin’s system
was a key factor for us. The original
proposal for the site was based on
installing stone-filled trenches with a
maximum void capacity of 30%.”
