Stormwater pit is a water collection pit or storage container for stormwater. It is not designed to hold all the run off but needs to be large enough to contain the water pouring into it long enough to allow it to drain through the drainage pipes at a rate that keeps up with the flow of water.

Drainage Pit is a dry well, a dry well is underground structure that disposes of unwanted water most commonly surface run off, and stormwater. In some cases grey water a larger open pit and artificial swale that receives storm water and dissipates it into the ground is called an infiltration basin or recharge basin.

Rubble Pit is a trench filled with blue metal gravel and topped with sand to help disperse and remove stormwater. (The pipes from the new addition) connect to the pit with a section of slotted pipe (in the pit) a section of slotted pipe (in the pit) dispersing water through the gravel.

Headwalls or wing walls improve the flow of water into and out of conduits provide anchoring support for the pipe and prevent dislodging under excessive pressures control erosion an scour resulting from high velocities and turbulences and to prevent adjacent soil from sloughing into the water way opening.

End wall The brick, concrete or stonework construction at the sides of an excavation built to carry a flat or arched roof also called sidewall.

Drainage in construction and residential properties.

Then once laid, must be compacted, so it can pass for a certified certificate, which is supplied by a Geo Tech business, so the council can approve for building.

There are a lot of customers being caught out at present, unknown to themselves, where they have the sand supplied from. That’s why customers should deal with a reputable earthmoving business, who deal with quality suppliers of sand for your sand pads. Some jobs at present customers have a bobcat come in and supply sand then the bobcat operator says to the customer after laying the sand pads, that the customer has to get there own certified certificate.

Leach Drains Supplied and Installed Dwellingup-Harvey-Pinjarra-Wandering

Leach drains are used to rid of effluent, which comes from septic tanks. 2 Disposal systems are best, as one is being used the other is rested. Resting one allows oil & grease collected in surrounding soil to be broken down, 2 tanks also last longer than a single septic tank.

Leach drains are best purchased in concrete as they last longer than plastic. If plastic tanks are not installed properly they can collapse after installation, where concrete is a stronger product and will not collapse or spilt.

Leach Drains is a tube structure which has holes in the sides they vary in length so it depends on the amount of liquid waste to be deposed of to the size of the leach drains. What type of soil it is installed in and how it is built.

Liquid waste enters one end of leach drains from the septic tank, then slowly seeps out the base and the sides through the holes into soil.

At Dobson Excavations we can assist in suppling the leach drains/septic tanks etc, we excavate the hole install and finish the job for you contact Bruce on 0414755306.
