Smart Controllers are the brain of your greywater system, responsible for opening and closing solenoid valves, managing filter backwash cycles, and water budgeting according to zone characteristics.

These controllers can sense when the basin is full of water and determine the correct zone to irrigate, which is crucial since the greywater supply isn't always reliable.

Some smart controllers can self-adjust according to changing weather conditions, and seasonally changing evapotranspiration rates, usually based on real-time ET values taken from active weather stations.

This means your system can adapt to dry spells or heavy rainfall, ensuring your plants get the right amount of water without wasting a drop.

Some systems use a water meter that measures all greywater and alternate water distributed to each zone, helping the controller make informed decisions about water allocation.

Make-Up Water is an essential aspect of a well-functioning greywater system. It refers to the supplementary water that is distributed through the greywater system to cover any irrigation requirement not fulfilled by the amount of greywater produced.

This supplementary water is usually freshwater, and it's distributed through the greywater system to ensure that all irrigation needs are met.

Make-up water can be added to the pumping basin through an "air gap" situation, which is a safety feature that prevents backflow into the potable water supply.

In some jurisdictions, make-up water can be directly connected to the graywater system, but this is only allowed if it's protected by an approved RPZ Backflow Prevention Device.

A gray water filtration system requires regular maintenance to ensure it continues to function properly. This includes checking and replacing the filter cartridges every 6-12 months.

The system's control panel should be monitored regularly to detect any issues or alerts, such as low water pressure or high pH levels. These alerts can be used to troubleshoot and fix problems before they cause damage.

Backwashing the system is also an essential part of maintenance, which should be done every 1-2 weeks to remove any debris or sediment that may have accumulated.

The self-cleaning filter feature uses a combination of air flow and ultrasonic cleaning to remove dust and debris from the filter, extending its lifespan.

This feature is particularly useful for areas with high dust levels, such as homes with pets or allergies.

The self-cleaning filter can clean the filter every 1-2 weeks, depending on usage and settings.

Regular cleaning of the filter can help maintain air quality and prevent filter clogs.

A well-functioning light is nearly odourless. This is a sign that it's working correctly.

The filter material should be moist, not dry or clogged. If it's dry, it may need to be replaced or cleaned.

The water exiting the light should be clear and odourless. If it's cloudy or has a strong smell, it's a sign that something is wrong.

Grey water is a complex mixture of water and contaminants, and ultrafiltration is a crucial step in removing organic substances and other impurities. This process is necessary before discharging grey water into a treatment system.

Ultrafiltration, or other filtration methods, are required to eliminate elevated levels of organic substances in grey water from household and building appliances. If this is too complicated to accomplish, grey water can be redirected to the sewage system or a nearby sewer.

The contaminants in grey water can cause it to decompose if not treated properly. This is why ultrafiltration is an essential step in the grey water treatment process.

Ultrafiltration can be an effective method for removing impurities from grey water, but it's not the only treatment option. Treatment of greywater may also include pre-filtration, sedimentation, flotation, post-filtration, or UV disinfection.

Here are some common ultrafiltration methods:

Irrigation is a crucial part of using a greywater filtration system. You can use greywater from showers, baths, and clothes washers to irrigate your plants, as it contains beneficial nutrients and biodegradable soaps.

Greywater is particularly suitable for native and ornamental plants, deciduous trees, and non-edible portions of landscape plants. It's also a great way to reuse water and reduce your water bill.

You can use a system like IrriGRAY, which pumps filtered greywater into a drip irrigation system. This allows you to monitor your irrigation system remotely from a smartphone or computer.
