I am looking for a specialist (AutoCAD / Visio / Illustrator / CorelDRAW) to create professional, aesthetic, and engineering-precise 2D/3D diagrams of water purification systems (domestic and industrial). The diagrams will be used in Commercial Proposals for clients.

An example of the desired detail and style is attached in the file (add your photo).

*One drawing needs to be made:

Check valve at the inlet;
Inlet buffer tank;
Pump with automation after the tank;
Big Blue 20" mechanical filter (with pressure gauges at the inlet and outlet, and bypass);
Filtration column with automatic control valve without tank;
Filtration column with automatic valve and salt tank;
Industrial reverse osmosis;
Mineral dosing station;
Accumulation tank of purified water 1000 liters;
Pump with automation for supplying purified water;
Big Blue 20" carbon filter;
Ultraviolet lamp

*Highlight or label with the directions of water flow all types of water. Inlet water, Drain to sewage, Purified water

*Show the drain to sewage from No. 5, No. 6, No. 7
*Show small overflow pipes from all tanks, salt tank

*Depict the sampling tap after each column and reverse osmosis

Main requirements for execution and detailing:

1. Language and design

Language of inscriptions: Ukrainian (all labels: “Inlet of raw water”, “Outlet of purified water”, “Discharge to sewage”, etc.).
Style: Neat, vector, maintained in a modern technical style (vector or semi-volume elements of equipment).
Output formats:
- PNG with a transparent background (high resolution).
- PDF for printing/inserting into KP.
- Source file (DWG, AI, CDR or Visio).

Budget: 900 UAH Deadline: 1 day

Good day, Denis. I will create a complete technological diagram specifically for the commercial proposal, not just a set of icons. First, I will verify 10 attachments and build the flow logic through all 12 positions. I will separately show the bypass and two pressure gauges near Big Blue, drains from No. 5–No. 7, overflows from the tanks and salt tank, and sampling taps after each column and osmosis.

I will differentiate the incoming, purified water and sewage by color and arrows, and all labels will be in Ukrainian. Within the first 4 hours after the start, I will provide a draft topology for checking the connections; after your confirmation — a final vector layout. The output will be: PNG with a transparent background in high resolution, PDF for printing/CP, and an editable vector file AI/SVG that opens in Illustrator/CorelDRAW.

The deadline is up to 24 hours after receiving confirmation of the format. To start, please clarify: A4 or A3, horizontal or vertical, and whether to indicate pipe diameters/working pressures, or just the technological sequence according to your list?

Budget: 800 UAH Deadline: 3 days

Good day, Denis! I carefully read the list: 12 items from the back valve at the entrance to the UV lamp, with a bypass and manometers on Big Blue, drains into the sewer from #5 to #7, overflows from all containers, and sampling taps after each column and osmosis — the composition is clear.

I will create a neat vector diagram in a modern technical style: Ukrainian labels, color coding of flows (incoming water / purified / drain into the sewer) with arrows indicating the direction of movement. The output will be: PNG with a transparent background (high-res), PDF for the KP, and an editable vector SVG/AI that can be edited in Illustrator/CorelDRAW. I honestly warn you: I work in vector (Illustrator-compatible), not in AutoCAD.

So you risk nothing: first, I will send a free sketch of 2-3 elements (filtration column, osmosis, pump) in the style of your example. If the style fits — I will complete all the drawings in 2 days. The price is lower than the market because I am gathering my first reviews here. I perform part of the work with the help of AI tools, and I manually check the final compliance with your list.

Question: what sheet format is needed for the KP — A4 or A3, horizontal?
