Understanding Water Meters

What are Water Meters?

A water meter is a device that measures the volume of water used by a residence or business. It is typically installed on the main water supply line to the building. Water meters are used to track water usage for billing purposes and to identify leaks.

Types of Water Meters

The two main types of water meters are positive displacement meters and velocity meters. Positive displacement meters measure water usage by measuring the volume of water that passes through the meter. In contrast, velocity meters measure water usage by measuring the speed of water flowing through the meter. In addition to positive displacement meters and velocity meters, there are a few other types of water meters that are used in specialized applications. These include compound meters, ultrasonic meters, and magnetic meters. Water meters offer several benefits, including accurate billing, leak detection, conservation, and infrastructure planning.


Importance of Accurate Water Meters

Accurate water meters play a crucial role in maintaining efficient water management practices and ensuring fair billing for water consumption. They provide several essential benefits, including:

  • Accurate Billing and Cost Allocation
  • Water Conservation and Leak Detection
  • Efficient Water Management
  • Promoting Water Conservation Efforts
  • Protecting Water Resources

Accurate water meters are essential tools for managing water resources effectively. They ensure fair billing, promote water conservation, and support efficient water management practices, contributing to the sustainable use of water resources for future generations.

Installation of New Water Meters

When and Why to Install New Water Meters

Installing new water meters is crucial for maintaining efficient water management practices and ensuring accurate billing for water consumption. Several conditions necessitate the replacement of existing water meters, including:

  • Age and Obsolescence

Installing new water meters is an ongoing process that ensures the accuracy of water usage measurement, promotes water conservation, and supports efficient water management practices. By replacing aging, damaged, or outdated meters with newer, more advanced models, water utilities can optimize their water distribution systems, reduce water loss, and provide reliable billing to their customers.


The Installation Process

The installation process for a new water meter typically involves the following steps:

  • Preparation
  • Meter Installation
  • Testing

Water Meters and Water Service Connections

Connecting Water Meters to Service Lines

The process of connecting water meters to service lines involves several crucial steps to ensure proper water flow and accurate water usage measurement.


Key Steps:

  • Location and Preparation: Determine the appropriate location, excavate a trench or pit, and install the curb stop.
  • Service Line Installation: Install the service line, a durable pipe connecting the curb stop to the meter. Bury the service line according to local codes.
  • Meter Vault or Pit Installation: Install the meter vault or pit to house the meter, valves, and fittings. Anchor the vault or pit for stability.
  • Meter Installation: Install the water meter inside the vault or pit, following manufacturer instructions. Connect the meter to the service line securely.
  • Valves and Backflow Preventer Installation: Install shut-off valves on both sides of the meter and a backflow preventer on the inlet side to prevent contamination.
  • Testing and Commissioning: Conduct a pressure test to check for leaks and commission the water meter to verify proper functioning.
  • Backfilling and Restoration: Backfill the excavated area and restore the surrounding area to its original condition.
  • Inspections and Permits: Obtain necessary permits and schedule inspections with local plumbing inspectors to ensure compliance.

Regulations and Compliance in Maryland

Maryland's regulations regarding water service connections and meters are overseen by the Maryland Department of the Environment (MDE) and the Maryland Public Service Commission (PSC). These agencies establish guidelines and enforce standards to ensure the proper installation, maintenance, and operation of water meters and service lines.

Key Regulations:

  • Water Meter Accuracy: Water meters must be accurate within a specified range to ensure fair billing practices. MDE regulations mandate regular testing and maintenance of water meters to maintain accuracy.
  • Backflow Prevention: Backflow prevention devices are required to prevent contaminated water from flowing back into the municipal water supply. MDE and PSC regulations dictate the installation and maintenance of backflow prevention devices.
  • Cross-Connection Control: Cross-connections occur when potable water supplies are connected to non-potable water sources. MDE and PSC regulations prohibit cross-connections to prevent contamination risks.
  • Meter Pit or Vault Construction: Meter pits or vaults must be constructed to protect the meter and service line from damage and provide easy access for maintenance. MDE regulations specify design and construction standards for meter pits and vaults.
  • Service Line Installation and Maintenance: Service lines must be made from approved materials and installed according to local codes. MDE regulations mandate proper installation and maintenance practices to ensure the integrity of service lines.

Compliance Requirements:

  • Water Utility Responsibility: Water utilities are responsible for maintaining and repairing water meters and service lines within their jurisdiction. They must adhere to MDE and PSC regulations to ensure compliance.
  • Property Owner Obligations: Property owners are responsible for maintaining the water service line and meter installation on their property. They must comply with local codes and regulations regarding meter access and maintenance.
  • Permits and Inspections: Obtaining necessary permits from local authorities is essential before commencing any work on water service connections or meters. Inspections are required to ensure compliance with regulations.
  • Enforcement Actions: MDE and PSC enforce their regulations through inspections, audits, and penalties for non-compliance. These actions aim to protect public health and ensure the integrity of Maryland's water infrastructure.

By adhering to Maryland's regulations regarding water service connections and meters, water utilities, property owners, and contractors can contribute to a safe, reliable, and sustainable water supply system.
