Less than three months after receiving approval from the U.S. Environmental Protection Agency for a trial lead service line replacement program, Denver Water began the process of removing lead service lines from its system.
本实用程序估计，64,000至84,000份住宅通过引线管接收水，并计划在15年内以约5亿美元的成本更换所有这些行。它现在正在使用中央水平台，数据过滤到可读仪表板中以管理15年的替换项目。
While Denver Water delivers lead-free water to homes and businesses, lead can enter the water as it moves through customers’ lead-containing plumbing and service lines. Any time that lead is introduced from pipes in a home, it has the potential to enter a municipal water system connected to that home.
No level of lead in drinking water is considered safe, so Denver Water wanted to move quickly to remediate lead levels when tests showed a spike in the level of lead in drinking water in 2012. The spike was found during routine water quality monitoring at homes with known lead and copper service lines. As part of the Lead and Copper Rule, Denver Water had been conducting these tests for nearly 30 years.
Colorado Department of Public Health and Environment officials ordered Denver Water to use orthophosphate to prevent the leaching of lead into water, but the utility rejected that idea. Orthophosphate could create other health risks for Denver Water customers, as well as the environment, utility officials said. Instead, Denver Water developed a plan to eradicate the source of lead in drinking water by identifying and replacing lead service lines in homes.
Since this project is expected to take 15 years, the utility planned interim steps including boosting the alkalinity of water to reduce corrosion in lead pipes, as well as a program that includes the testing of tap water and providing free water filter pitchers to affected residents. This plan was accepted by The Colorado Department of Public Health and Environment last December.

In order to move quickly after EPA approval of the plan late last year, Denver Water needed a centralized way to manage the program. The utility needed a method to capture, house and interpret data from the city’s water sampling program, as well as manage the supply, distribution and correct usage of pitcher and filter kits, which the city is providing to affected residents.

Residents with homes identified as having a possible lead service line were notified this spring. As service lines are replaced or disrupted, Denver Water is offering residents a pitcher and filter kit. 120Water’s platform will trigger the delivery of approximately 150,000 NSF 53-certified pitchers and filter kits and 1.2 million replacement filters along with clear instructions for usage. This is being done at no cost to residents over the trial’s three-year period.
A few weeks before receiving the pitcher and filter kit, the 120Water platform automates sending residents mail to introduce the program so they know the pitcher kits are coming and know why and how to use them.

丹佛水also is using the 120Water platform to manage its water sampling program. This includes pre-lead service line water testing at about 30,000 taps. These tests require the cooperation of residents, so education and follow up are important elements that often require resources and attention. As such, the platform also automates the mailing of testing kits to affected residents, along with instructions on how residents should perform the tests and return the sample. Once analyzed by a laboratory, associated data is housed in the 120Water platform, which automates the communication of tap test results to Denver Water and residents both electronically and by mail.
120Water平台也集中了丹佛的服务线库存数据，包括GIS，历史纸质数据，客户信息和人口统计数据。数据统一并呈现在仪表板中，使实用程序完整地了解了引导服务线替换和程序的进度。
衡量成功
丹佛水must replace an average of 7% of its lead service lines each year for the next three years in order to extend EPA approval for the remaining 12 years. This also includes implementing a public outreach and education program about the dangers of lead in drinking water and the progress the utility is making in reducing it.
尽可能多的努力自动化将是效用高度复杂努力的成功的关键。
