Estates, body corporates, hotels, offices and schools: keeping supply on, borehole and rain-tank water, quality complaints and looking after the plant.
Building water guide
I farm
Borehole, dam and river water for irrigation, livestock and the farmhouse, in plain language.
Farm water guide
I make food or drink
Food and beverage plants, bakeries, commercial kitchens and pack-houses: boilers, combi steamers, wash-down, CIP and what the auditor asks for.
Food and drink water guide
I want better water at home

Water for my home
Lead time and stock on every line
When the catalogue opens, every SKU will show its lead-time band and stock status before you ask. No “POA” walls, no phoning to find out if it exists.
Exact variant specifications
Visually similar models are never ambiguous: every variant will statein plain words how it differs — coil voltage, seal material, length, rating.
If we don’t stock it, we source it
Indent items — brought in against your order — will be listed in the tables with real lead-time bands, not hidden behind a “call us” note. The ability to source is the value.
The product catalogue opens soon
The catalogue pages are still being built out with the full DWT range. Until they open, the branches quote by phone and email as they always have.
What it will be
A living trade catalogue, not a brochure. The site is generated from DWT’s own master product data, so the range, specifications, stock status and lead-time bands you see are the ones the branches work from — when a line changes in the branch, it changes on the site.
- Full specifications on every line, label by label
- Indicative lead-time band (A–E) and stock status on every line — no POA walls
- Indent and made-to-order items listed as first-class rows with real lead-time bands
- A variant note on every model so similar codes are never ambiguous
- Datasheets and drawings wherever they exist, one click from the line
- Order codes decoded — the DWT model-code key alongside the range
- Compare up to four lines side by side, differences highlighted
- Add to quote from any row; the list goes to the branch you choose
No prices are published on the site. Quotes are issued per enquiry, with confirmed pricing and lead times from the branch, usually within one working day. Indicative lead-time bands: A = Ex-stock (0–3 days) · B = 2–4 weeks · C = 6–8 weeks · D = 8–12 weeks · E = Made-to-order (lead time varies with the build).

The reference library
Look it up before you ask — the working documents behind specification, free to use.
1003manufacturer spec sheets
Data sheets and manuals across 51 brands — including documents the manufacturers no longer publish. Searchable, downloadable.
12calculators and references
Scaling indices, dosing, RO recovery, media sizing and code converters — each ends with what the result means for selection.
62plain-language guides
Component basics, when to use which, and how the options compare — written for engineers earlier in their careers.
Applications
Borehole water treatment
Iron, manganese, turbidity and hardness — the four problems that define South African borehole water, and the equipment that solves them.
Brackish water reverse osmosis
Feed TDS from 1 000 to 8 000 mg/L: element selection, staging and the pretreatment rules that decide whether an RO plant runs for months or years.
Food and beverage filtration
Process water, product water and CIP support for producers where water is an ingredient, not a utility.
Rainwater harvesting filtration
From roof to tap: the staged filtration that turns stored rainwater into a reliable, odour-free supply.
Municipal backup and buffer systems
Tank-buffered municipal supply: keeping stored water clean, pressurised and safe through interruptions.

Not sure what you need?
Tell a branch what you are trying to do and they will point you to the right thing. It helps to have: what the water is for (a house, a farm, a plant), where it comes from, the flow you need, any equipment already fitted, and a water analysis if you have one.
Johannesburg also answers on +27 75 084 5743 and salesjhb@definitivewater.co.za. Mon to Thu 08:30 to 16:30, Fri 08:30 to 16:00.
