Septic Tanks Supplied and Installed in Concrete from Perth-Lake Clifton-Myalup-Bunbury

Septic Tanks Supplied and Installed in Concrete from Perth-Lake Clifton-Myalup-Bunbury


Supply of concrete products and installation at Dobson Excavations, we not only excavate the hole for the septic tanks but we supply them also. We are your one stop earthmoving business, we cater to our customers a service, so customers do not have to hire different business to complete different jobs. At Dobson Excavations we can complete the job from start to finish.

If you check out our web page you will be able to view our work and machinery.

As for the installation of Septic Tanks in concrete, septic tanks are used for disposal of sewage and effluent, so concrete is less likely to break or spilt compare to plastic, yes plastic is cheaper, but do want to have to in the end waste more money years or months later to have to replace them if they spilt or cave in, at least with concrete you know they will most probably out last you.

Septic tanks are installed with either 2 leach drains or 2 sets of soak well tanks, These systems are called alternating systems as they have a diverter box which can change the flow of effluent allowing one half of the soak wells or one of the leach drains to be shut off at anytime. This allows the unused portion to dry out which rejuvenates the soils ability to receive effluent.

All the concrete products we supply are approved to Australian Standard AS/NZS 1546.

Farm Dam Construction and Dam Clean Outs Perth -Rural-Metro

Farm Dam Construction and Perth-Rural-Metro

Farm Dam Construction is not a case of digging a hole and waiting for it to fill with water. Many farm dams fail because they were not constructed or planned out correctly. Most farm dams are compacted earth structures built at depressions, gullies or hillsides. Farm dams should be planned and built with the same care you would apply to building a house.

Things to consider when planning a Farm Dam Construction

• Government regulations that apply to your Farm Dam Construction check with your local council for regulations.

• Size of your dam allowing for evaporation and Farm requirements.

• Where to build your Farm Dam: A Gully usually is a good place to site a dam because it reduces the amount of earthworks and the overall cost. However, not everyone has the advantage of a gully site on their property; many farm dams are built on hillsides.
Two important considerations, the catchment yield and the soil type at the site.

• Preparing your site: Before building starts, the area to be covered by the embankment, spillway and excavation should be stripped of all topsoil, roots and vegetation (including trees and stumps). Store the topsoil for use in the completion of the embankment and spillway.

• Building your dam :The successful completion of an earth dam relies heavily on achieving a well-compacted embankment.
Apart from soil compaction, other major construction considerations include: • the cut-off trench • exposed rock • spillways • clay cores • embankment batters • freeboard • settlement of the embankment • crest width • topsoil use.

• Maintaining your dam. To allow the storage to fulfil its function it is important to carry out regular maintenance. It also helps to observe the following.
Ensure topsoil cover of at least 150 mm.
Establish a grass cover on the embankment and spillway as soon as possible. A grass that mats, such as kikuyu, is preferable to a grass that tufts.
Do not let trees or shrubs grow on the embankment, spillway or spillway outlet slope. Roots might disturb the compacted soil and provide a seepage path for water, while trees or shrubs in the spillway area will restrict the flow of flood water.
It is worthwhile to choose an earthmoving contractor who has experience and a good work record. Not every contractor has the experience or the ability to build a dam.  At Dobson Excavations we have this experience.

Which can cause Erosion of house pads, footings, Rising dam to walls, Floor and Foundation damage.

Soak well tanks work by collecting rainwater diverted by pipes attached to gutters, holes in the tanks allow seepage into the soil, they are installed underground.

They come in various sizes and traffic able lids are available if vehicles need to travel over them.

Soak wells Supplied and Installed all Areas

Soak wells Supplied and Installed in all Areas

A soak wells divert and control water run off, from House and Shed roofs etc, water travels down drain pipes which run into the soak wells, soak wells have holes in the tanks which allow water to seep out into the ground.

Soak wells are made from a variety of materials and capacities, but usually concrete is the best option as they last a lot longer and a trafficable lid can be installed if you have area where a vehicle travels over it, as plastic can split and collapse.

Before you consider installing  soak wells in WA, you should familiarise yourself with your local shire council’s regulations. By law in Western Australia home owners have an obligation to confine any stormwater run-off within the boundaries of their property.

Rain water which is not effectively managed on your property can cause a range of issues. Apart from the obvious effects of erosion on your property and your neighbours, a build-up of water against your property can cause many issues including:

Erosion of house stumps and building subsidence
Subsidence of footings and concrete pads
Rising damp to walls and footings and flooring
Wood rot
And let’s not forget termites love a drink and you could be the key provider

Unless you effectively manage rainwater on your property, you could be faced with carrying out extensive repairs and renovations to your home, both inside and out, above and below. However, if you install  soak wells designed to accommodate the expected levels of rain water for your property, you are likely to avoid significant maintenance costs and avoid issues with your neighbours.

To work out what size soak wells you require, Simply calculate the area to be roofed or paved and use the above formula to find out the required amount of soak well volume. Eg. 60m2 of paved area. 60 x 0.0125 = 0.75 Required soak well size = 900 x 1200 Note: Always round up to the nearest volume.
