Bored well for the garden: Efficient and economical irrigation in 2025

Why is a borehole dedicated to the garden worth it?

Irrigating a garden with mains water means high bills, low pressure during peak hours and sometimes restrictions during dry periods. A bored well for the garden solves all these problems: water available at any time, at minimal costs, without dependence on municipal suppliers.

Which areas can be irrigated from a drilled well?

Well flow rate	Irrigable area	Applications
0.5–1 mc/h	200–500 sq m	Small gardens, flowers, vegetables
1–3 mc/h	500–2,000 sq m	Medium gardens, lawns, small orchards
3–5 mc/h	2,000–5,000 sq m	Orchards, vineyards, small greenhouses
5+ mc/h	5,000+ sq m	Farms, large greenhouses, intensive irrigation

How deep should a garden well be?

Unlike a drinking water well, the garden well does not need the same quality standards, which means that:

• Wells of 15–40 m are sufficient in areas with shallow water table
• 40–80 m — for higher flows or areas with a deep water table
• Water does not require DSP authorization if it is not consumed by humans or animals
• The water management permit (ANAR) may be necessary if the flow exceeds 10 mc/day

The pump suitable for well irrigation

Submersible pumps

The most reliable solution for drilled wells. It is mounted in the well, below the water level.

• Advantages: High reliability, no priming required, quiet
• Flow: 1–20 mc/h depending on the model
• Cost: 800–4,000 lei (without assembly)
• Popular examples: Grundfos SQ, Pedrollo 4SR, Franklin Electric

Surface pumps

Suitable for shallow wells (up to 8 m dynamic level).

• Advantages: Cheaper, easy to replace
• Limitation: Only works if the water is less than 8 m from the pump
• Cost: 400–1,500 lei

Hydrophor pumps

Complete pressure tank system — ensures constant pressure and extends pump life by reducing frequent starts.

Bore Well Compatible Irrigation Systems

1. Sprinkler irrigation (Sprinklere)

• Ideal for lawns and large areas
• Requires pressure of 2–4 bar and flow rate of 1–3 mc/h
• Installation cost: 1,500–5,000 lei for 500 sqm

2. Drip irrigation

• Ideal for vegetables, fruit trees, vineyards
• Consumes 40–60% less water compared to sprinkling
• Required pressure: 0.5–2 bar (easier to reach)
• Installation cost: 800–3,000 lei for 500 sqm

3. Manual irrigation (hose + pump)

• The simplest and cheapest solution
• Flexible, no fixed installation
• No automation required

Full Costs — Garden Well Drilled 2025

Component	Cost
Drilling 20–40 m (Ø 125 mm)	2,800–7,200 lei
Submersible pump + installation	1,500–4,000 lei
Water heater + electrical panel	800–2,000 lei
Pipelines and connections	500–1,500 lei
Drip irrigation system (500 sqm)	800–2,500 lei
Total full investment	6,400–17,200 lei

The investment pays for itself in 2–4 years compared to the cost of mains water for an average garden.

Real irrigation savings

A 500 m2 garden consumes approximately 150–250 cubic meters of water during the irrigation season (May–September). At an average price of 8–12 lei/m2 (public network), bills can reach 1,200–3,000 lei/season. With an own well, the cost is reduced to the electricity of the pump: 80–150 lei/season.

Maintenance of the garden well

A well drilled for irrigation requires simpler maintenance than one for domestic consumption. However, periodic denisipari remains important — every 3–7 years, depending on the quality of the aquifer.

Conclusion

A bore well for the garden is one of the most profitable investments for owners of houses with land. Combine independence from the network with real savings of thousands of lei per year. Make sure you avoid common drilling mistakes and choose an experienced company for a lasting result.
