Not every project site has access to sewer connections or reticulated water. For remote building sites, civil works projects, army camps, and large outdoor events, temporary tank infrastructure is the practical solution for managing waste and potable water safely and compliantly.
Serious About Waste supplies a full range of holding tanks across South East Queensland, including 4000L waste holding tanks, 5000L grey water and potable water tanks, and 1000L IBC tanks for smaller applications. This guide covers each tank type, its specifications, suitable use cases, and how servicing works for remote and complex sites.
Why Holding Tanks Are Needed on Remote and Off-Grid Sites
Civil construction sites, defence installations, remote work camps, and large-scale events routinely operate in locations without access to mains sewer or town water supply. Without proper temporary tank infrastructure, waste management on these sites becomes non-compliant and creates real environmental and public health risks.
Queensland’s environmental protection legislation requires that liquid waste, including grey water and sewage, is managed through approved systems and disposed of at EPA-authorised facilities. Hiring certified holding tanks from us, combined with scheduled vacuum truck pump-outs, provides a fully compliant solution with complete documentation.
4000L Waste Holding Tank
Specifications
- Capacity: 4000 litres
- Dimensions: 3865mm L x 2400mm W x 660mm H
- Weight capacity: 5000kg, plus 8 people
- Heavy duty steel frame construction
- Special locator tab lifting points
- Towing hook on frame for easy on-site positioning
Suitable Applications
The 4000L waste holding tank is the standard choice for remote building and civil construction sites, special events, army camp locations, and any site without a sewer connection. Its towing hook allows the tank to be repositioned on site using standard equipment, and the locator tab lifting points make delivery and placement straightforward even in tight or complex layouts.
Tanks can be serviced on a schedule that suits your project, from daily pump-outs for high-usage sites to weekly or monthly arrangements for lower-volume applications.
5000L Grey Water Tank
Specifications
- Capacity: up to 5000 litres
- Dimensions: 1800mm H x 2000mm D
- Weight: 112.5kg empty
Suitable Applications
The 5000L grey water tank is designed to collect and hold sullage waste from ablution blocks and shower water from portable shower facilities. It is suited to both temporary and long-term sites that require grey water containment without a permanent drainage connection. For more information on grey water management and complementary services, see our grey water tank hire page.
Civil works sites, remote work camps, army installations, and multi-day events with portable shower hire commonly use 5000L grey water tanks alongside portable toilet and ablution block infrastructure.
5000L Potable Water Tank
Specifications
- Capacity: Up to 5000 litres
- Dimensions: 1800mm H x 2000mm D
- Weight: 112.5kg empty
- For potable water storage only
Suitable Applications
The 5000L potable water tank provides safe, clean drinking water on sites without access to town water supply. It is suitable for remote construction and civil works sites, army camps, and any project where potable water needs to be available on an ongoing basis.
We can also arrange potable water deliveries to your tank on a schedule that suits your site’s consumption rate, ensuring a continuous supply without reliance on existing water infrastructure.
1000L IBC Tank
Specifications
- Capacity: up to 1000 litres
- Dimensions: 1000mm W x 1000mm D x 1100mm H
- Weight: 60kg empty, up to 1000kg full
Suitable Applications
The 1000L IBC tank is suited to sites with lower foot traffic or smaller-scale liquid waste needs. It handles grey water, catering waste, and recycled water, making it a flexible option for food service areas at events, small remote sites, and locations where a larger tank is not practical.
IBC tanks are compact and easy to position, making them ideal as a supplementary tank alongside larger infrastructure or as a standalone solution for smaller operations.
