#TDIWH—January 5, 2015: History of Raleigh’s Water; 2006: Long Term 2 ESWTR

0105 EB-Bain-Plant_State-ArchivesJanuary 5, 2015: Article published on the History of Raleigh’s Water. “Raleigh’s first go at creating water infrastructure was in the early 1800s when only about 1,000 residents called the city home. In 1818 the city built a water wheel in the Rocky Branch creek, which pumped water through wooden pipes to a water tower.

“Think barrels,” wrote Huler in a follow-up email. “Staves held together by wire, wound around almost like a spring.”

Unfortunately, Raleigh’s first try at a citywide system was, to put it bluntly, a total disaster. The mud and silt that accompanied the water caused the pipes to burst and within a few years the city returned to wells and pumps.

0105 Water-Resevoir_state-archives-771x612In the mid 1880s, with the population at a booming 10,000 people, Raleigh decided to give it another try. In 1886 the city built a real pump, just south of downtown, pulling water from Walnut Creek. The steam-powered water treatment plant filtered 2 million gallons per day sending the water to a reservoir and then to a 100,000-gallon water tower that still stands downtown.

By 1910 Raleigh had 55 miles of water mains running beneath the streets.”

January 5, 2006: Long Term 2 Enhanced Surface Water Treatment Rule finalized by USEPA. “The purpose of the LT2 rule is to reduce illness linked with the contaminant Cryptosporidium and other disease-causing microorganisms in drinking water. The rule will supplement existing regulations by targeting additional Cryptosporidium treatment requirements to higher risk systems. This rule also contains provisions to reduce risks from uncovered finished water reservoirs and to ensure that systems maintain microbial protection when they take steps to decrease the formation of disinfection byproducts that result from chemical water treatment….The final rule is effective on March 6, 2006.”

Commentary: This regulation was a critical component of the Reg Neg and FACA negotiations that I participated in from 1992 to 2000. Utilities were given a number of years to develop compliance plans to meet this relatively complex drinking water regulation.
