The main difference between sewer and stormwater drains are what flows through them. Sewer systems will transfer sewage and waste while stormwater drains are there to have rainwater flow through them. Private property owners will be responsible to repair, install and manage both sewage and stormwater drainage in their property. Local councils and Sydney Water will be responsible for sewage and stormwater management.

When the stormwater drains are located on public lands, such as parks or roads, then the local council will be responsible for them. If private property pays for council rates or any other type of place such as public housing then they will also be responsible for the stormwater drains. Any land or property that is owned privately then they will be responsible for maintaining, repairing and installing stormwater drains.

A gutter is a part of the stormwater drainage system to catch rainwater and transfer it away from the building. They mostly run on the roofs on the outside of buildings where the roof will divert the water to the gutters. It is important that the gutters are not blocked so they can properly remove rainwater from the foundations of the building.

Pressure Reducing Valves (PRV) are designed to reduce incoming water or steam pressure to a safer constant predetermined downstream level. Depending on the type of valve, the downstream pressure is established by a pressure adjustment setting on the valve or by an external sensor.

Stormwater pits are where water is collected and stored for a short amount of time before entering pipes. It allows runoff water to be collected and helps keep the stormwater drains from flooding or overflowing. They will not store water for a long period of time but will help with a steady water flow. They are often made of precast concrete with a crate to prevent leaves and debris from entering them.

Stormwater is water that flows after it has rained on surfaces. The storm water will hit roofs, footpaths and roads and will most times enter the street gutters that local governments and councils govern. When the drainage system is located in private property it aims to remove the water from the place and into local water catchments owned by local councils and Sydney Water.

Stormwater drains and sewage systems both transport water and other items away from a property. The stormwater system focuses on transferring rainwater that would normally run on surfaces away correctly. Sewage systems are there to transport sewage from the building out into sewage plants. Here at Optimised Plumbing Services our Emergency Plumber team is here to work with sewer and stormwater pipes at any time.

There are two types of water pressure reducing valves-- direct acting and pilot operated-- which use globe or angle style bodies. Direct acting valves are the more popular water pressure reducing valves, consisting of globe-type bodies with a spring-loaded, heat-resistant diaphragm connected to the outlet of the valve that acts upon a spring.  This spring holds a pre-set tension on the valve seat installed with a pressure equalizing mechanism for precise water pressure control.

Downpipes connect to the gutters and will direct the water caught by the gutters into stormwater pits and drains. They are mostly positioned vertically so the water can fall directly into the next sections of the stormwater drainage system. The end of the downpipe will be pointed directly to the drain or pit and will help limit splashing and water entering the building.

After the water has been collected from the building and directed away it will be diverted to the local councils’ catchment or similar water collection system. In public spaces, such as footpaths, a street gutter will be how the water is gathered to the water collection systems. Drains and pipes will smoothly transport the water and help prevent water flooding.
