Because storm water pits are relatively small fixtures, their importance is often overlooked easily.
This article discusses two things that everything homeowner should know about the cleaning of these pits.
Pits Need To Be Cleaned More Frequently Than Drains And Pipes
In order to understand the logic behind this thinking, it's important to understand how storm water pits work. Pits are used as temporary storage locations for rainwater before such water is allowed into the storm water drainage system. By holding the water temporarily, pits make it possible to maintain a constant rate of water flow through the drain.
Pits usually come with leaf guards and other filtration devices designed to trap silt and debris suspended in storm water.
It would therefore be correct to assert that the quantity of debris that reaches a storm water drain is nothing compared to that which settles at the bottom of the pit and that which is trapped by the various filtration devices.
If your drain gets clogged (and needs to be cleaned) after a month of exposure to heavy rain, then perhaps the storm water pit connected to it needs to be cleaned on a fortnightly basis during the same period.
Storm Water Pit Cleaning Is Not Your Average DIY Activity
Pits often look simple enough and their aluminium/plastic lids shouldn't be difficult for a DIY-minded homeowner to lift off if he or she intends to do some cleaning.
However, you might want to think twice before you choose the DIY-route to a clean storm water pit. For one, effective cleaning of these fixtures is done using vacuum excavation.
The mentioned technique involves the use of a vacuum tanker that has an intake nozzle connected to it. The intake nozzle is directed into the pit and it sucks in the accumulated silt and debris, delivering it straight into a storage tank.
You'll need to rent out one of these tankers if you're to do an effective cleaning job. A professional cleaning company will charge you for labour, but they won't charge you for the equipment. The actual dollar amount you might end up saving is unlikely to justify the time and effort you'll put in.
Secondly, there's the fact that many pits are fitted with submersible pumps. There's the risk that you'll damage the pump in yours in the course of DIY cleaning and you might have to pay for its repair or replacement. If the pump gets damaged in the hands of a professional cleaning company, they'll be responsible for repair/replacement costs.
