Steel-plate tanks
NPI steel tanks for water storage, defined per project. Dimensions, capacity and plate treatment are confirmed with the manufacturer in the proposal.
Water storage · South Africa
Water storage in South Africa
Steel-plate tanks with the pumping around them: filling, pressure boosting, level control and automation, with hydraulic design and commissioning support.
Since 1968
The SILGAR name in pumping and filtration.
Six leading brands
Caprari, Flygt, Lowara, Grundfos, KSB and Sulzer.
Hydraulic design
System curve, duty point and surge protection.
Commissioning support
On site or remote, agreed for each project.
What we supply
Fill pumping
Pumps sized to the filling flow, started and stopped by level, with dry-run protection.
Pressure boosting from the tank
Variable-speed sets with redundancy that hold pressure constant whatever the demand.
Level control and remote monitoring
Level probes and transducers, low and high alarms and remote reading, so the state of the tank is known without being there.
Filtration and metering
Inlet filtration (LAMA, Azud, Filtromatic, Arkal, STF) and Hidroconta meters and flow meters, with Bermad valves.
Prefabricated septic tanks and treatment plants
Premier Tech septic tanks and treatment plants, on a project basis, with the pumping and control around them.
What shapes a project in South Africa
South Africa is a semi-arid country with recurring drought and water restrictions. The grid faces scheduled outages, which weighs on pumping decisions: storage, solar and variable speed are part of the design. It is also a market with demanding technical standards and well-established local suppliers.
What we design for
- Power outages: volume that gives autonomy, and pumping with soft start
- Demanding standards and technical documentation
- Solar assistance and variable speed on pumping
- Local suppliers: we complement, with engineering and specific equipment
Typical applications
- Steel-plate tanks for municipalities and industry
- Storage to ride through power outages, with pumping and soft start
- Stations with variable speed and solar assistance
- Prefabricated septic tanks and treatment plants, on a project basis
Brands we work with
We choose the brand for each duty — flow, head, water and climate — not the other way round.
Caprari
Borehole submersible pumps and high-flow pumps, of Italian origin.
Flygt
Submersible pumps and mixers for wastewater, drainage and process.
Lowara
Multistage pumps, pressure-boosting sets and submersible pumps.
Grundfos
Pumps with integrated drives, pressure-boosting sets and borehole pumps.
KSB
Large pumps for water, industry and supply.
Sulzer
High-flow pumps for water, wastewater and industry.
We also work with: NPI · Premier Tech · LAMA · Azud · Filtromatic · Arkal · STF · Bermad · Hidroconta
The brands mentioned belong to their respective owners. NextGreen is not an official distributor of any of them: we supply equipment from several brands, chosen for each installation.
How a project runs
From first contact to commissioning, in five steps.
Brief
Flow, head, water source and quality, available power and site conditions.
Hydraulic design
System curve, pump selection and duty point, surge protection and control concept.
Proposal
Datasheets, curves and an equipment list, ready for your designer and your client.
Supply
Export packing and logistics. Delivery terms (Incoterms) are set out in the proposal.
Commissioning and support
Start-up support, on site or remote, and a spare-parts plan.
Our own installations, in Portugal
We do not show projects we have not done. These are NextGreen installations in Portugal.
Frequently asked questions
What tank capacities are available?
Capacity and dimensions are defined per project and confirmed with the manufacturer in the proposal. Tell us the volume you need and the project location.
Do you supply only the tank or also the pumping?
Pumping, pressure boosting, level control and automation are our core. The tank comes from the manufacturer; erection is normally done by a local company, with our technical support.
Can the pumping sets run on solar power?
They can be sized for solar assistance or hybrid operation, with variable speed. It depends on power, running hours and solar radiation; we assess each case.
What do you need to prepare a proposal?
Required volume, water source and quality, filling flow, service pressure, available power and the project location.
Which brands do you work with?
NPI tanks; Premier Tech tanks and treatment plants; Caprari, Flygt, Lowara, Grundfos, KSB and Sulzer pumps; LAMA, Azud, Filtromatic, Arkal and STF filtration. We are not an official distributor of any of them.
