Taiwan Water Meter Installation Principles
Context & Purpose
This skill defines the operational parameters and constraints for installing water meters (總表, 分表, 獨立表) in Taiwan, as regulated by the Taiwan Water Corporation (台灣自來水股份有限公司用戶表位設置原則).
Parameters & Classification
| Meter Type | Size (Diameter) | Description |
|---|
| Large Meter (大表) | ≧ 50 mm | - |
| Small Meter (小表) | ≦ 40 mm | - |
| Master Meter (總表) | - | Meter followed by other meters for individual billing. |
| Sub Meter (分表) | - | Meter following a master meter. |
| Independent Meter (獨立表) | - | Directly supplies user, no subsequent billing meters. |
| Smart Meter (智慧表) | - | Part of AMR system, transmits signals to TWC. |
Location Rules
- General Safety: Must be in safe spaces allowing easy meter reading, replacement, maintenance, and good drainage.
- Prohibited Areas: Inside toilets, bathrooms, underground basements (for master/independent meters), or back of the house. Must not obstruct traffic/pedestrians.
- Master/Independent Meters:
- Should be placed within the property line, adjacent to the road building line.
- Allowed on open spaces behind arcades, flower beds, green areas, or beside stairways.
- Prohibited in driveways or parking spaces.
- Sub Meters (Apartments/Condos):
- Default location is the roof (must have a fixed stairway and railing).
- If roof access is impossible, meters can be grouped in a dedicated Meter Room on specific floors (NOT in the basement). The room needs a 4-inch floor drain and a 35cm threshold.
Clearances & Dimensions
- Vertical Clearance: Meter bottom must be ≧ 2 cm above the ground.
- Recessed Spaces (崁入式表位):
- Axis to roof/gas meter clearance: ≧ 30 cm
- Axis to wall clearance: ≧ 10 cm
- For ≦25mm meters: Space ≧ 50(W) x 55(H) x 20(D) cm
- For 40mm meters: Space ≧ 70(W) x 65(H) x 22(D) cm
Execution Logic for AI
When checking MEP plans:
- Verify meter location against prohibited areas (basement, toilets, driveways).
- Check if sub-meters are placed on the roof. If not, verify the existence of a valid meter room.
- Validate clear dimensions for recessed meters.
