For potable water, portland cement is used; for sewage it is common to use sulfate resisting or high alumina cement.
And Michigan recently brokered a proposed deal that includes $70 million to upgrade Highland Park's water infrastructure, including replacing water mains and service lines. The city, which buys ...
The 2014 Flint water crisis was caused by a combination of source water change and a lack of corrosion control. The new, higher-CSMR water not only dissolved lead and iron from the pipes themselves, but also broke up previous layers of lead-containing rusty scale in pipes, allowing them to enter the water supply.

Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.Rust consists of hydrous iron(III) oxides (Fe 2 O 3 ·nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron.
Starting with Stone Road and Harper and Hale drives this summer, Streetsboro is planning to undertake $8 million to $9 million in water line work.
