Sprinkler and Drip Irrigation Systems
This section documents the outdoor irrigation systems that supply water to the lawn, garden, and flower beds around the duplex.
There are two essentially unrelated irrigation systems:
- Sprinkler System – services the lawn areas
- Drip Irrigation System – services the garden and flower beds
Although they are physically close in some places, they operate independently and are, therefore, documented separately.
Why This System Matters
Much of this system is:
- Underground
- Out of sight
- Difficult to reason about when something goes wrong
Without documentation, it can be hard to answer basic questions such as:
- Where does this water come from?
- Which valve controls this zone?
- Is a problem electrical, mechanical, or water-related?
- Is it safe to dig here?
This documentation exists to help answer those questions.
High-Level Overview
Sensors and Automation (Supporting Role)
Some parts of the drip irrigation system are monitored by sensors and automation.
These include:
- A water depth sensor in the NW catchment tank
- A pressure sensor on the pressure side of the drip irrigation pump
- An ESPHome controller that reports sensor data to Home Assistant
These components:
- Do not move water themselves
- Exist to provide visibility and protection
They are documented here only in terms of how they support the irrigation system.
What Is Documented Elsewhere
This overview intentionally avoids deep detail.
Detailed information is documented in the following sections:
- Sprinkler zones, valve boxes, and PVC routing
- Drip irrigation tank details and plumbing
- Exact sensor models, wiring, and automation logic
- Maintenance and failure scenarios
