Irrigation system for the condominium garden
An efficient irrigation system keeps the shared greenery healthy and cuts water waste. Here is how to handle design, maintenance, consumption and cost allocation among owners, with the resolutions you need.
In this guide
The irrigation system of the condominium garden serves a common part, the greenery, and its management falls on the condominium. A good system, automated with a controller and sensors, keeps lawn and plants healthy while reducing waste and costs. Management covers seasonal start-up, periodic maintenance, control of water consumption and the allocation of costs among owners according to their thousandths (millesimi). Significant works must be resolved by the meeting.
The garden and the system as common parts
The garden, unless the deed provides otherwise, is a common part under Article 1117 of the Italian Civil Code, and so are the irrigation system and its accessories (buried pipes, solenoid valves, controller, sprinklers). The care of the greenery and the functioning of the system therefore fall within the administrator's ordinary management, who handles maintenance and awards the gardening service. As with any common part, the condominium is the custodian and is liable for damage arising from neglected maintenance, for example flooding from breaks or leaks.
Designing an efficient system
A well-sized system adapts the water supply to the different zones of the garden: the lawn has different needs from flower beds, hedges and trees. Splitting into sectors with solenoid valves allows different areas to be watered at different times, avoiding waste. The programmable controller manages times and durations, preferring evening or night hours to reduce evaporation. Rain and soil-moisture sensors suspend irrigation when it is not needed, cutting consumption. For the lawn, pop-up sprinklers are suitable; for beds and hedges, drip lines are often more efficient.
- Split into sectors with solenoid valves for uniform zones.
- Programmable controller with differentiated time bands and durations.
- Rain sensor and moisture probe to suspend unnecessary irrigation.
- Drip lines for beds and hedges, pop-up sprinklers for the lawn.
- Seasonal scheduling, more intense in summer and reduced in mid-seasons.
Seasonal maintenance
The system must be looked after throughout the year. In spring, start-up is carried out, checking solenoid valves, sprinklers and leaks. During the season, pressure, sprinkler orientation and the absence of dry or flooded zones are checked periodically. In autumn, in frost-prone areas, winterisation with draining of the pipes is essential to avoid winter breaks. Neglecting these steps leads to failures, water waste and higher repair costs.
Water consumption and meters
Irrigation affects the water bill of the common parts. Fitting the system with a dedicated meter allows the garden's consumption to be measured separately from other common uses. Monitoring consumption helps to detect hidden leaks, often signalled by an abnormal increase, and to assess the effectiveness of saving measures. In drought periods, municipal orders may limit the use of drinking water for irrigation: the administrator must comply with them and inform the owners.
Who decides and with what majorities
Ordinary maintenance of the system and the award of the gardening service fall within the administrator's powers under Article 1130 of the Civil Code. Building a new system or fully replacing it is an extraordinary expense and must be resolved by the meeting with the majorities under Article 1136. If the work introduces a system that was not there before, it may qualify as an innovation under Article 1120. The resolution should state the design, the amount, the contractor and the timing, and provide for a periodic maintenance contract.
Cost allocation
The construction, maintenance and water costs of the shared garden's irrigation system are shared among the owners according to their thousandths (millesimi) of ownership, under Article 1123 of the Civil Code, unless the deed or regulation provides a specific table for the greenery. If the garden serves only part of the building, for example a single block, the cost is charged only to the owners who enjoy it. Correctly distinguishing benefits makes the statement transparent and prevents disputes.
With AmministraPro the administrator can schedule seasonal irrigation maintenance, monitor the shared greenery's water consumption and allocate costs among owners in a traceable and verifiable way. The features are described on the /funzioni page and the plans on the /prezzi page.
