Question 1

What is the difference between a sewer and storm drain?

Accepted Answer

A sewer drain is likely found inside structures like homes or offices. It is responsible for carrying all the wastes and sewage from said structures towards treatment plants before being discharged. Meanwhile, storm drains are for the stormwaters during or after rainfall. This drainage system carries rainwater from roofs, driveways, footpaths, and roads. Soil, litter, and other organic materials and residues will also flow into stormwater drains. Their most notable difference is that wastewater from sewage drains are treated first before being released while stormwater goes straight to its final destination.

Question 2

What is sewer drainage?

Accepted Answer

The sewer drainage system consists of the underground pipes in your homes. It will carry your waste and other sewerage from your kitchens, bathrooms, sinks, laundry and other plumbing units in your homes. As mentioned, wastewater from sewer drains will flow straight to treatment plants first before being discharged into respective waterways. When there is a leak in your sewer line, it can ramp up your water bill and create potential health hazards and stinky smells. To determine if you have leaking pipes, investigate constant trickles or banging and knocking sounds around your home along with any unusually damp floors or grounds and when you notice an unpleasant smell.

Question 3

How does stormwater drainage work?

Accepted Answer

Traditionally, stormwater drainage systems use conveyancing. The water will be conveyed to discharge points such as rivers, lakes, and oceans from collection areas like houses and streets. Conveyancing will remove most of the water quickly from collection areas. But this method has the highest potential of getting the pipes blocked. Now, there is a water sensitive urban design (WSUD) that will slow the flow of the stormwater runoff. Natural filtration will occur wherein the water will reach the discharge points, cleaned and filtered by soil.

Question 4

How do you install a stormwater drain?

Accepted Answer

Before installing water drains, there are some factors that you must first consider:

Check the soil type.
The soil must have sufficient depth.
Ensure a lower groundwater table for a more effective infiltration.
Design the system with regards to its terrain.
Check local government regulations.
Ensure that there are no illegal sewer and stormwater drains cross-connections.

Here are a few tips for stormwater drainage installation:

Use a roof, tarpaulin or an awning to prevent the rain from washing sediments into stormwater.
You can divert stormwaters from your driveways, roofs, patios or paths towards vegetated areas around your home. This will filter the stormwater before directing them to the drainage system.
