Treated Effluent Lines

Treated effluent lines generally refer to pipelines that carry treated wastewater from a treatment plant to be discharged into surface waters – rivers, creeks, lakes, etc. – or it may be pumped into groundwater sources. Some communities have created a dual water system allowing the use of treated effluent for lawn irrigation. Other areas may send effluent to golf courses or agricultural areas. Obviously, treated effluent must meet federal environmental standards prior to its discharge. When treated effluent is discharged into a river or stream, it often improves the quality of water in that river or stream.

AMERICAN is the nation’s premier manufacturer of products for treated effluent lines by virtue of its offering ductile iron pipe, valves and spiral-welded steel pipe.

AMERICAN developed cement-mortar lining for iron pipe in 1923. Cement lining, coupled with ductile iron pipe’s larger nominal inside diameter, provides a smooth, efficient flow. That means less pumping is needed to move water through the line, which results in lower energy costs over the life of the line. And because less energy is required, greenhouse gas emissions from utility operations are significantly reduced.

AMERICAN has developed numerous joints that ensure an effective and easily assembled method of restraint between pipes and between pipes and valves.

AMERICAN’s spiral-welded steel pipe also features several joint options to best meet the needs of individual treated effluent situations requiring larger diameters.
