Irrigation Maintenance for Napa Valley Estates
QWEL-certified water management
WATER THAT'S MEASURED & MANAGED YEAR-ROUND
Penning Landscapes is a family-owned, single-source landscape firm that has designed, built, and maintained estate gardens across Napa Valley since 1988.
Irrigation maintenance is the part of that work that keeps water doing exactly what it should, reaching the right plants, in the right amount, in every season. On a large estate, that takes planning, auditing, and steady year-round attention, all handled by one in-house team that already knows the property.
WHAT'S INCLUDED
Irrigation maintenance has two halves that work together: managing the water itself, and maintaining the system that delivers it.
Water Management & Planning
Penning provides an irrigation system plan, audits, regular meter readings and monitoring of water levels, plus an intricate management plan for optimal seasonal water usage. The focus is ensuring water conservation and cost-effective usage, and every reading and adjustment is documented, so you keep a clear record across the year.

System Care & Adjustment
Penning handles installation of efficient irrigation systems via zone maps and controller charts, and provides year-round maintenance, including inspection, repair, and adjustment of sprinklers and drip lines, plus on-call repairs between visits. Zones are tuned as the seasons and the plantings change.

One Firm, From Build to Upkeep
Penning designs, builds, and then maintains the landscapes in its care, so the team managing your water already knows the soil, the plantings, and the history of the site, not an outside irrigation contractor seeing it for the first time. That continuity is a large part of why these maintenance relationships last for years, and it keeps irrigation working in step with plant health rather than as a separate job.
A life with a garden where plants, trees,
flowers, and vegetables thrive is a life well lived.

Frequently Asked Questions
What does Penning's irrigation maintenance include?
Penning's irrigation maintenance combines water management with irrigation-system care. The water side covers irrigation plans, audits, regular meter readings, seasonal water planning, and water conservation. The system side covers zone mapping, controller charts, and year-round inspection, repair, and adjustment of sprinklers and drip lines. It is delivered in-house by the firm's QWEL-certified team across Napa Valley and Sonoma Valley.
Who is irrigation maintenance for?
It is for the people responsible for high-value Napa Valley and Sonoma Valley properties where water needs to be efficient, documented, and well managed, most often estate managers, private estate owners, and winery property directors. The common thread is wanting one accountable partner for the water rather than a separate irrigation vendor to coordinate. Penning serves all three through its maintenance work.
How does Penning support water efficiency on a large estate?
Penning supports water efficiency by auditing the existing system, mapping zones, reading meters, and adjusting irrigation to the season and the plants. Water use is managed and documented, so the estate manager keeps a clear record. The work is led by QWEL-certified water management trained through the California Water Efficiency Partnership.
What water-management certification does the Penning team hold?
The team's water work is QWEL-certified water management, the Qualified Water Efficient Landscaper credential from the California Water Efficiency Partnership, which carries WaterSense recognition from the EPA. The firm is also a member of the Irrigation Association. These credentials apply directly to auditing and tuning irrigation on large properties.
How often is an irrigation system inspected and adjusted?
The team inspects, repairs, and adjusts irrigation year-round rather than only at the start of the season. Sprinklers and drip lines are checked and tuned as conditions change, and meters are read regularly where the property warrants it. A seasonal water plan sets the schedule for the year ahead.
We already have an irrigation system. Can Penning take it over?
Yes. Penning begins with a complimentary site visit and an audit of the existing system, then maps zones and documents how the system is performing before recommending any change. From there, irrigation becomes part of the ongoing maintenance relationship rather than a separate service to coordinate.
What happens if something breaks between visits?
Penning handles on-call repairs, so a broken line, a stuck valve, or a failed zone gets fixed without waiting for the next scheduled visit. For a property coming from another vendor, Penning can also modify an existing system rather than replace it, after auditing how it currently performs.
Schedule a complimentary site visit
We'll review how your irrigation system is performing, discuss the needs of your landscape through the seasons, and show you how measured, documented, and adjusted water management supports the long-term health of your estate.
