KUB, like other utilities nationwide, continues to face the challenge of replacing aging infrastructure. Century II, an infrastructure management program KUB launched in May 2007, is designed to be an investment in our next 100 years of quality service—and in the quality of life in our community.
Century II is KUB's proactive long-range program to improve and maintain the electric, natural gas, water, and wastewater systems for our customers. It includes the maintenance and replacement strategies for each system that were in place before Century II and establishes sustainable replacement cycles. It moves KUB into its second century of service by improving each system through sound planning, resource allocation, and continued, but accelerated, investment.
Funding for Century II is on track to help KUB continue to provide safe, reliable utility services and meet customer needs—now and in the future. Replacement projects are expensive, but the investment in our community’s health and future is worth it. By anticipating and addressing needs now, customers will realize long-term benefits and experience even fewer service interruptions.
Century II includes all four services, but at any given time, each may be at a different stage of assessment, prioritization, planning, or implementation. For an overview of the replacement focus for each service, please see below. You can also find more information in our Century II Information Sheet and Frequently Asked Questions section.
Our lives and businesses run on electricity. KUB understands how vital it is to provide reliable service to current customers and to support future growth.
The electric system continues to focus on replacing aging poles, overhead wires, and underground cables. We are on a sustainable life-cycle replacement program for those assets. We are also concentrating on our substations, some of which have been in service since the 1940s. Timely maintenance over the years means they still provide good service, but we need to upgrade or replace some equipment to ensure it continues to meet customers’ needs as electric demand—and technologies—change. As we replace transmission poles, we are also adding fiber-optic lines between substations to improve data communication.
The Natural Gas System
KUB continues to look at the need to replace older pipe types and extend service to provide a safe, reliable system to serve current and future customers. We have had numerous gas asset replacement programs for decades, continually renewing the system, which we rolled into Century II. The 40-year cast iron/ductile pipe program, which began in 1980, has been recently completed.
The natural gas system continues to focus on replacing older pipe types with plastic pipe that has a longer life and lower maintenance costs. Revenues over this timeframe will also help fund new construction, support regulatory programs, and increase safety surveys and corrosion monitoring.
We are proud of our safe, high-quality water and committed to maintaining the system that delivers it. Although KUB's water system has stood the test of time well, some components are nearing the end of their useful life.
KUB was able to accelerate our rate of replacement for older pipes under the 10-year Century II financial plan approved in 2011. KUB doubled the rate for removing older galvanized and cast iron pipe from our system. The plan includes funding for completely removing outdated galvanized main from our system by 2024.
Sanitary sewer overflows and aging wastewater system infrastructure are growing concerns across our nation. KUB, like many other utilities, is under a federal Consent Decree (CD) to make system improvements. KUB launched Partners Acting for a Cleaner Environment (PACE 10) in 2004, and when the Environmental Protection Agency issued our CD in 2005, we included those requirements in the PACE 10 program. After the last of the 134 collection system projects required under the CD were completed in 2014, KUB transitioned all wastewater system improvement projects under the Century II program with our other systems.
KUB’s final project under the CD is a major upgrade to the Kuwahee Wastewater Treatment Plant on Neyland Drive. This $50M project is on schedule to be complete ahead of the June 30, 2021 deadline.
Under Century II, KUB will continue to evaluate our entire wastewater collection system through its Continuing Sewer System Assessment Program (CSSAP). Data collected through the CSSAP is used to address inflow and infiltration and other causes of sanitary sewer overflows by maintaining or restoring capacity and structural integrity throughout our wastewater system. KUB will continue to upgrade the wastewater system on a sustainable life cycle.
