Is this the best OSD system ever?

1 Is this the best OSD system ever? 1. You may not even need a costly traditional OSD system at all. Use our Landscape Tanks as your Structural Retaining Wall, Front Fnce, Pool or Pergola Surround and you may be able to eliminate the costly traditional OSD system altogether. 2. Designed using The Upper Parramatta River Catchment Authority Handbook of 2005 as a model. (Handbook developed with assistance from Baulkham Hills Shire Council, Blacktown City Council, Holroyd City Council and Parramatta City Council) Landscape Tanks design engineers have designed the Landscape Tanks system with the above handbook as a guide, offering a huge variety of variations, to suit the many local council requirements. 3 Modular above or below ground use resulting in massive cost saving for customers and also eliminating costly in situ construction mistakes. Installation does not require traditional trades and may be installed and plumbed in a matter of hours not weeks. 4. They may also be buried to a height that suits and are an ideal for basin or rain garden replacement when space is limited. OSD Basins take up an enormous amount of room and are not ideal OSD solutions. Our Landscape Tanks offer a great alternative. 5. Imagine having your OSD system incorporated into your attractive, quality structural retaining wall, front fence of pool surround. Sounds impossible doesn't it, well its not and lots of people are doing it already and are loving the stunning results and great savings. 6. Replaces hugely costly and often troublesome in situ builds. In situ builds can result in a trade persons lack of understanding of OSD systems resulting in system failures and costly repairs.

2 Clever Design. If you design your build correctly using our Landscape Tanks as a retaining wall or front fence you may not need a traditional costly OSD system at all. OSD System - Front Fence - Retaining Wall - Raised Garden Bed, - Water Tank - Melbourne 50mpa Concrete - No Footings Required - Pre Engineered For Use (Empty) Structural Retaining Walls/Front Fences /OSD Systems - Three Sizes - Australia Wide. OSD System - Front Fence - Retaining Wall Raised garden Bed - Sydney Domestic and Commercial - Inbuilt Fully Draining HED Tank with S/S Machined Orifice and RH 30/30 Removable Mesh Screen. Endless Storage Capacity. Copyright

3 Domestic And Commercial - Above Or Below Ground Features as standard with all OSD systems. HED unit with internal 3mm S/S Machined Orifice Plate. Removable RH 30/30 Gal mesh filter. HED tank and reservoirs drain fully empty to stormwater. Modular by design for endless storage capacity. Access hinged grates or gal cover plate as appropriate. Above or below ground application. HED tank may also drain through bottom as required. HED tanks may be in centre or at either end as required. Multiple HED tank and orifice plates optional as required. Easy push fit cast in interconnecting O ring seals top and bottom to suit. Ventilation 100mm ports in each corner of planter top at rear. High grade pre cast 50mpa concrete with SL62 mesh and 10mm bar. No footings required and very Cost effective. Ideal (space poor) basin replacement - May be used as water gardens. 3

5 HED Tank may be located anywhere in the row of tanks. Row of tanks to be placed on 1 o incline to ensure full discharge. 1 2 o is unnoticeable to the naked eye. Tanks may be placed in a straight line or at right angles to suit. 1-2 o incline in direction of HED tank ensures all reservoir tanks empty completely. 1% incline Ponding is eliminated The Landscape Tanks OSD system features a HED tank built into the first (or centre) tank in the system. Tanks are joined using cast in place O ring easy fit seals for endless storage capacity. 5

6 Endless configuration and design options. Hard surface run off - above or below ground. Hard surface run off water may be directed into either end or into the side of any of the tanks as required, directly into the HED tank. Tanks on either side of the HED tank form the reservoir. Ideal for driveways. Planter box is above ground for great effect and growing of plants. Note drainage slot on then end of row of tanks. In this design the roof water may be directed into the Landscape Tanks via plumbing anywhere in the line of tanks. The row of tanks may also have one end as OSD system and the other end as water storage, whilst still maintaining the integrity of the retaining wall. 6

7 Supplementary information Standard flow path. Emergency overflow may be located as required. 7

8 Access through planter top galvanised class B hinged grate. Planter top with access Flat top with access not trafficable. 600mm x 600mm hinged grate - Class B 900mm x 600mm hinged grate - class B Roof water only through standard tank 600mm tank filter optional Lightweight Galvanised mild steel lockable hatch for flat top or planter top optional 8

9 Supplementary information. Tanks may be configured to form any shape, which suits the property or customer. See standard part numbers (below) but custom units are also available. Easy fit interconnection EPDM rubber O ring seals. Interconnection easy fit seals: (EPDM rubber) The Landscape Tanks use their own patented highly effective proven easy fit O ring seal to join the tanks together. This results in virtually no plumbing works required to join the tanks together. The seals are cast into the tanks during manufacture, enabling the PVC pipes to be inserted from either direction in one simple motion. They are very flexible and provide a water tight seal even in the most challenging environments. Seals can be expected to last a lifetime and may be placed anywhere in the tanks as required. Seal sizes range from 50mm, 90mm and 100mm. 9

12 Upper Parramatta River Catchment Trust On Site Stormwater Detention Handbook fourth edition Some critical design parameters are listed below. NOTE: The above exert from the Upper Parramatta River Catchment Authority handbook clearly states that above ground OSD systems (such as Landscape Tanks) are preferred and underground storage reservoirs are to be avoided if at all possible. The handbook also states that underground systems are: More expensive, Difficult to inspect, Difficult to maintain, Dangerous to work in for maintenance. All these recommendations are compelling reasons to design the very attractive Landscape Tanks as your next OSD System. Multi purpose them as a retaining wall and the cost savings can be in the tens of thousands of dollars as a traditional OSD system may not be required. 12

13 Upper Parramatta River Catchment Trust On Site Stormwater Detention Handbook fourth edition Some further critical design cost parameters are listed below as further evidence of the benefits of using Landscape Tanks as your OSD system. Signage. All OSD system may require signage of some description. Consult your hydraulics engineer, builder or council in this regard as each council is different. Three common signs are shown below and are available from Landscape Tanks as required. 13
