What You Need to Know About Drainage Excavation

When planning any type of construction project, whether it is a large multi-level building or a retaining wall for a suburban back yard, the chances are very high that the natural flow of water, both surface and underground, will be disturbed by the foundation work. As a result, having a plan to manage any drainage issues should always be part of the initial scope of work.

Common Excavation Types

In addition to managing unexpected drainage issues during a project, there are also many other situations where drainage excavations are required. Public works projects such as construction of sewerage and greywater treatment plants, maintenance and renewal work in existing plants, and underground services such as gas, electricity, water, telecommunications and drainage pipes are common excavations associated with essential services.

Drainage Excavations are Heavily Regulated

Add to these applications the types of drainage work involved in residential and commercial developments and excavations are almost certain to be required. A range of Australian Standards, building codes and legislation, both state and local government, regulate such planned drainage excavations. In addition, there are requirements for certain drainage works to be inspected, and specific instructions for licensing and the keeping of relevant registers.

Many types of excavations can be hazardous, so we offer our services as experienced operators of earthmoving and wet plant machinery. Our clients include tradies, land developers, builders, local councils and homeowners. Here at Dee Gees Bobcats we perform the excavation of drainage systems for everything from residential septic system installations to storm drains.

Septic Systems Still Needed

Excavations for septic systems may become less common as more and more of the new developments in our local government area are required to be connected to the sewerage system. However, in the semi-rural and rural areas on the outskirts of the city our services are still in demand for drainage and septic installations in new builds. Septic systems provide rural dwellers with modern toilet facilities and along with greywater systems that use recycled water assist householders to conserve their potable water.

Storm Drains an Essential Control Method

As in other parts of our country, we have extreme weather events ranging from long stretches of time without rain to torrential downpours that overwhelm our rivers and suburban drainage systems. Storm drains therefore are an important part of our work and one of the major methods available to minimise the damage and inconvenience such events cause. Their installation is also regulated to ensure that storm water moves along the drains and away from buildings and infrastructure.
