Tap the map: 1st tap = water source, 2nd tap = tank, then add points along the real pipe route. Drag a point to adjust; tap a route point to remove it.

A. Water source (well / borewell / pond)

Paste location or Google Maps link

B. Tank / field where water is needed

Paste location or Google Maps link

How to take a location in Google Maps: touch and hold the spot until a red pin drops → tap the coordinates shown (like 26.9124, 75.7873) to copy → come back here and press Paste.

2 Water source

Source type Water level depth in summer (m)

Depth of water below ground while the pump is running (lowest level). Ask the owner or check the borewell record.

3 Tank & water need

Where does the water go?

Tank height above ground (m)

Daily water requirement (litres/day)

Height of the tank inlet. Use 0 for a ground-level tank or pond.

Pipeline size (inner diameter)

Choose your pipe size, or leave Auto and the app picks the best size. The pump HP changes with the pipe size.

More settings (optional)

Pumping (sun) hours per day

Pump depth below water level (m)

Fittings / valve / bend losses (% of pipe friction)

Pipe material

Actual pipe length (m) – leave empty to use GPS distance

Extra length for bends & slack on GPS distance (%)

Source ground level (m, MSL)

Tank ground level (m, MSL)

Ground levels fill automatically from satellite data (±3–10 m). If you know better values, type them.

Pump efficiency (%)

Motor + controller efficiency (%)

Solar panel size (Wp)

Array oversize factor

Array Wp = electrical input × oversize factor (covers dust, heat & low-sun losses). 1.25–1.4 is common.
