Whether you have an external grease trap or internal dux converter in your commercial kitchen, we recommend that it be cleaned every one to three months. Local councils are cracking down on Grease Trap and Dux Converter cleaning and are starting to insist on regular cleaning programs being put in place.

Bain’s take extreme pride in their workmanship and insist on leaving your business how they found it. We also like to service and clean them between 5am and 8am to ensure all odours have gone by the time you open your doors for customers.

A Thorough Clean

Regular, correct cleaning of your Grease Trap/Dux Converter is not just for compliance, but will save you money in the long-run! Both lids need to be removed to make sure the grease trap is entirely cleaned out.

Regular cleaning of fat and sediment ensures only water goes into the council sewer therefore avoiding costly and inconvenient blockages, and messy flooding in your premises causing a health hazard. If you wait too long before cleaning your grease trap or dux converter you can also risk damaging it, resulting in messy overflows. This can cost you up to $2000 to replace, not to mention shutting down trading for a few days while it’s fixed or installed.

Fully Compliant

We’ll also make sure your liquid waste is disposed of correctly, so you avoid costly fines of up to $35,000. As a company we are fully code compliant and independently audited every three years by Liquid Systems Ltd. View our current Waste MINZ certificate.

You Would Be Amazed How Much Dirt and Sand a Storm/wastewater Drainage System Can Collect in a Short Period of Time.

Expert Solutions

We remove 15 tonnes of sand and silt a month from one large catchment chamber that is only a part of their entire waste/stormwater drainage system. Without regular cleaning, it wouldn’t take long for these drains and entire system to fill up. The system would progressively reduce its ability to handle their wastewater flow, until their drainage system would fail, resulting in flooding on site, the possible temporary closure of their operation and all the unnecessary disruption and inconvenience this would cause.

When this happens they would not only need a liquids waste disposal contractor to empty out all their catchment chambers, but also a water jetting company to unblock and clear all their drains.

If their system needs to be pumped to finally discharge their wastewater, they have also run the risk of damaging their existing pumps and filling their pump chambers, which will require further cleaning and removal of more sand/silt.

A Thorough Clean

It’s a lot cheaper to have a programmed maintenance cleaning procedure in place to ensure your entire waste/stormwater system remains clean and can operate at full capacity and thereby eliminating the risk of any disruption and costly repairs.

Fully Compliant

We’ll also help you make sure your liquid waste is disposed of correctly, so you avoid costly fines of up to $35,000. As a company we are fully code compliant and independently audited every three years by Liquid Systems Ltd. View our current Waste MINZ certificate.

Most dairy farms have either a two day retention sump or a smaller sump near their cowshed which collects the run off and washing from the dairy shed and yard, often transferring the waste water to a pond or spray irrigator.

If their system needs to be pumped to finally discharge their wastewater, they have also run the risk of damaging their existing pumps and filling their pump chambers, which will require further cleaning and removal of more sand/silt.

Clean Streams Requirements?

During the season, the build-up of silt, sand and stones brought onto the yard normally by the cows’ feet builds up in the pump chamber.

A Thorough Clean

To minimise any damage to the pump and the build up or complete blockage of irrigator lines, more and more farmers are regularly emptying and cleaning out their chambers to remove the abrasive silt, sand and stones. These chambers may vary in size but are generally relative to the size of the farming operation and in most cases take Bain Liquids Disposal less than a couple of hours to clean out completely.
