Drainage excavation in Australia
Posted on: 26 October 2015
The rapid development of Australia's residential, commercial and industrial sectors have increased the amount of impermeable areas, hence increasing runoff volume and frequency. The impact of this result could have adverse impact on the natural environment, hence the great efforts by the Australian government to minimize this impact through drainage excavation. The process involves the removal of rock or soil from a given site in order to form an open face or a hole used for drainage. Heavy tools and machinery or in some cases explosives are used to perform the task. It is important to bear in mind that drainage excavation could involve a lot of risks and in this case the Australian government has put in place a cord of practice in the line of drainage excavation. Drainage excavation by companies like Minpex Drainage aims to meet the following objectives:
- To minimize the impacts on waterways from changing their natural flow in cases of floods and runoff, whose flow, frequency and velocity have been affected adversely by urban development.
- To guarantee that the new urban developments do not have any adverse impact (increased levels of toxics, sediments and litter) on the downstream areas received by other waterways. This measure put in place ensures that good water quality, reducing any threatening impact on aquatic and riparian life forms.
- To safeguard Australia's watercourses from pollution which includes toxicants, nutrients sediment, litter and any changes to water chemistry. To achieve this plumbing companies have tried integrating drainage into the urban environment. The integration of these elements of drainage systems create a lot of recreational prospects and also enhance visual amenity.
- To certify that all the new habitable buildings are protected from flooding in major storms and new subdivisions provide overland flow paths for all surface flows. The drainage excavation works are designed in consideration of the extent, duration and velocity of floods on newly built assets and environments to ensure human safety.
- Management of flows to make sure that floods do not bring undesirable risks to the community. To do this drainage systems are designed in a manner that ensures flows do not collect to cause any hazards or inconveniences and by also ensuring that piped drains are of adequate capacity to bear storms and guarantee flooding doesn't happen.
- Encourage storm water reuse as a part of all urban development to increase water conversation and also reduce consumption of portable water.
The drainage excavation works in Australia place a lot of emphasis on safety to ensure the community as well as the stakeholders in the plumbing sector are not presented with any safety issues.
