Arvada’s Direction


Infrastructure Master Plan

Due: December 2025

Principle: Provides safe and efficient connections to modes of transportation, including transit, streets, sidewalks, and bikeways with a focus on enhanced technology at high-priority intersections improving safety and minimizing traffic congestion.


The purpose of infrastructure master planning is to sustain the City's infrastructure.  The work includes assessing current asset condition, developing a list of projects for capital improvement and reinvestment, estimating project costs, and prioritizing those projects on short and long-term schedules.

This strategic result covers the City's work to update master plans by December 2021.  


It is important for the City to frequently review and update Infrastructure Master Plans to ensure we are taking lasting care of infrastructure assets and we appropriately plan for reinvestment, replacement and maintenance of infrastructure assets.

Performance Measures

Wastewater Pipeline Maintenance


This is a milestone measurement: the City is investing $2 million annually in upgrading the sewer collection system. The majority of the work is on 15 inch or smaller pipelines. The goal is to complete the 15 inch or smaller pipeline upgrades by 2023 and perform work on the larger pipelines as needed, with completion by 2033. The upgrades will have a lifecycle of 75 years.


This milestone goal is important for several reasons. Mostly, it insures the physical and environmental integrity of our sanitary sewer system for decades to come. Through the process of Cured In Place Pipe lining, (CIPP) and limited pipe replacement, the reliability and efficiency of the sanitary sewer system continues to measurably improve.

 In the last 15 years, we have seen the average number of sewer blockages or back-ups in the City owned system drop from 10 per year to 1.5 per year currently.  We have been able to greatly reduce the amount of infiltration or ground water entering in to the sewer pipes which have increased the capacity within the system as well as saving significant costs to the Denver Metro Wastewater Reclamation District for treatment.

 The completion of this milestone by 2023 will allow our focus and resources to be directed to any needed improvements on larger sewer lines to insure capacity and integrity to meet the needs of all future growth within the City.


The 2017 CIPP lining project included 53,359 ft. and 3,508 ft. of open cut replacement.

The 2018 CIPP lining project included 70,973 ft. and 4,765 ft. in the open cut project. 75,738 ft. total. 14.34 miles.

The 2019 CIPP lining project was limited to 48,365 ft. or 9.16 miles. There were no open cut sewer replacements done in 2019.  There are two factors that will impact the volume of work completed in 2020. First is the major Ralston trunk line sewer replacement project. This 6.4 million dollar project is the largest sanitary sewer capital project in the City in over 30 years. As a result, some funding from the CIPP and open cut replacement programs were directed to the Ralston Trunk project. In addition, the proposed 2020  CIPP lining project will include much larger diameter pipes. (10" to 15" pipe sizes) This drives the cost of lining per lineal foot much higher. The result will be less volume overall than in recent years. However, this should not impact our goal of completion by 2023.

IN 2019, the system has 432.4 miles of pipe that are 15" and smaller.

The 2020 CIPP program includes 5.07 miles of sewer rehabilitation.

Waterline Breaks 


The City is committed to maintaining the investment in the water system infrastructure. One measure of success is the number of water pipeline breaks that occur annually. The goal or target is to have 25 or fewer water distribution pipeline breaks annually. Data entered each quarter is cumulative. 

The goal and target is 4 or less per 100 miles while the industry standard is 12 per 100 miles. 


By Investing in water main replacement and taking the time to analyze and prioritize existing infrastructure, the workforce has been able to reduce the number of pipeline breaks each year. 

Keeping the system in good condition improves customer service, saves money, enhances efficiency and assists in keeping water rates as low as possible.

Reducing water distribution pipeline breaks also plays a role in overall water conservation as one break can result in the loss of millions of gallons of water.
