- Remote and island sites
Selecting a plant for a remote or island site.
Remote sites are constrained by power, access and the people who run the plant, not only by the flow. This guide walks through what to check before a plant is sized.

What makes a site "remote"
A site is "remote" when the infrastructure a treatment plant normally relies on is partly missing or intermittent. The conditions below tend to appear together, and they change what can be installed and who can operate it.
- No sewer connection — there is no municipal network to discharge to, so the plant has to treat to the required standard on site.
- Unstable or off-grid power — the site may run on a generator or a weak grid, so power quality and continuity become design inputs.
- Island and archipelago logistics — the plant may travel by sea and then by barge or road before it reaches the site.
- Seasonal access — a road, jetty or airstrip may be usable only in part of the year, which fixes when delivery and installation can happen.
- Construction camps — a temporary population that needs treatment now and may need the plant moved later.
- Mining, oil and gas facilities — operations that sit far from any network and cannot tolerate a treatment failure.
Site constraints checklist
- Power supply and stability — the source, the capacity available and how steady it is through the day.
- Available land and footprint — how much space is clear for the plant and for any future units.
- Road or port access and lifting — what can reach the site, and what can lift a container at the delivery point.
- Climate — heat, humidity, salt and storm exposure at the site.
- Operator availability — who runs and maintains the plant, and how much attention they can give it.
- Discharge point and standard — where the treated water goes and to what standard.
- Seasonal occupancy — how the population swings between peak and off season.
- Future expansion — whether the plant will need to grow with the site.
Why a containerized plant fits
Shop-fabricated
The treatment train is assembled, piped and wired before it leaves the factory, so site work is limited.
Delivered as one unit
A complete plant travels as a standard ISO container that can move by sea, barge and road to the site.
Minimal civil works
A level foundation and the inlet, outlet and power connections are enough to place the plant.
Relocatable
When the site moves or closes, the plant can be lifted and moved to the next location.
Modular expansion
Capacity can be added later by bringing in additional container modules.
Pre-commissioned before shipment
The assembled plant is tested at the factory before it ships, which shortens commissioning on site.
Selection steps
- 1Size by flow and organic load — daily flow and influent strength set the treatment capacity.
- 2Fix the number of container modules — the required capacity decides how many container units the plant needs.
- 3Match power and control — the power available on site decides the drives, the control mode and any standby arrangement.
- 4Plan the delivery route — sea, barge and road are checked against the container dimensions and the lifting available.
- 5Define the installation scope — foundation, connections, power, water and commissioning are agreed before shipment.
What to send us
- Location and access to the site — port, road or barge route and the lifting available.
- Design flow (m³/day).
- Power supply available on site — the source and how stable it is.
- Discharge point and discharge standard.
- Project stage — feasibility, design, tender or construction.
Delivery and logistics
Containerized plants travel as standard ISO containers and are loaded at the factory with export documentation for each shipment. Route planning, loading arrangement and delivery schedule: [to be confirmed with factory].
