Water Main Extension

Extensions of a permanent main

Extensions of permanent water mains are constructed by local improvement district (LID) processes that meet our standards and specifications.

You can learn about the LID process online or contact our LID Representative Heather Croston at hcroston@cityoftacoma.org or 253-331-3830.

This work can also be constructed through a privately financed contract (see information below).

Water Main Design

Tacoma Water prepares the plans and specifications of water main designs and estimates the engineering charge for the preparation of plans and specifications.

Developers pay a deposit equal to the estimate cost. Actual costs of the work are billed against this deposit.

It takes 1 to 2 weeks to prepare the Preliminary Design Estimate and Design Agreement.

Design timeline dependencies include:

• Predesign meeting 1-2 weeks from date of design deposit payment
• Drafting and Engineering, depending on the size of the project (12 weeks)
• 90% design is reviewed by external stakeholders and is not included in the above drafting and engineering timeline. Either,
  • Varies up to 8 weeks for Fire Marshall review on Pierce County projects
  • Varies up to 12 weeks for Planning and Development Services & City of Tacoma Engineering review

Water Main Construction

Developers enter into an agreement with a contractor of their choice and Tacoma Water for construction of the water main extensions. When considering contractors, look for experience in ductile iron water main construction with a record of successful completions of similar scope.

Developers pay the constructions costs directly to the contractor. A performance bond or other security and certificates showing appropriate liability insurance are required.

Developers are responsible for costs and expenses incurred by Tacoma Water for construction inspection and other related work. Prior to construction, a second deposit in the estimated amount for construction inspection, testing, and sampling is due to Tacoma Water. Upon completion of the project, developers are either refunded the unused amount or billed the cost overrun.

Construction sequence:

• Preparation of construction contract (1 week)
• Construction contract review and approval by TPU (1 to 2 weeks)
• Pre-construction meeting is scheduled once contracts are signed and approved, construction staking is complete, and materials are on-site. Typically 2 weeks from completion of construction paperwork.
• Construction timeline is provided by developer and contractor.

Easements

Please note: Typical level of service is 8 weeks.

Not completing the easement process in a timely fashion impacts the ability to purchase new water meters and/or property transfers. 

Developers are required to provide a 20-foot wide easement over the entire length of the water main, fire hydrant, service laterals, and meters.

The developer’s Professional Land Surveyor prepares and submits the legal description of the easement to Tacoma Water for review and processing.

The transfer of privately financed water mains to the City is on the condition that the developer provides necessary and proper easements.

When water mains are installed on private property which is not owned by the developer and part of the subject development, easements must be recorded prior to installation.

Easements for water mains must specifically name Tacoma Water and then accepted by the City. Developers provide a notarized statement of the water main construction costs. This cost statement also provides the legal description of property having contributed its share toward the cost of constructing the mains. Only those properties abutting upon the water main construction qualify as contributing properties.

Fire Hydrant Use Permit and Flow Test

Fire Hydrant Use Permit

Please note: Typical level of service is about 5 days.

Temporary water service may be supplied through the use of a fire hydrant after obtaining a permit. This is needed if you require a temporary water source for construction purposes or to fill a tanker truck when you do not have a permanent water service.
