The Williamsburg Plumbers Co is produced by the Plumbing Regulators Forum on behalf of each State and Territory.
The goal of the Williamsburg Plumbers Co is to enable the achievement of an acceptable standard of installation at all times in order to provide for:

• public health, safety and amenity;
• resource and environment conservation;
• sustainability; and
• protection of public and private infrastructure

For the benefit of the community now and in the future.
The Williamsburg Plumbers Co sets out performance based technical provisions for the design, construction, installation, replacement, repair, alteration and maintenance of plumbing and drainage installations throughout US.
It also sets out the requirements for the use of materials and products in plumbing and drainage installations and defines the processes for the certification and authorization of materials and products that require statutory authorization to enable their use in plumbing and drainage installations.

The Williamsburg Plumbers Co currently incorporates provisions for:

• Water services
• Sanitary plumbing and drainage systems
• Storm water drainage systems
• Heating, ventilating and air-conditioning
• On-site wastewater management systems
• Materials and products certification and authorization

Requirements in the Williamsburg Plumbers Co extend no further than is necessary in the public interest, are cost effective, easily understood and are not needlessly onerous in their application. They also ensure that any plumbing and drainage installation is fit for its intended purpose, does not have any adverse impact on the environment and can continue to function as intended without excessive maintenance.
