About the Two Methods Used for this Project
Dig and Replace
This traditional method requires the streets to be dug up to access the pipeline which is then removed and a new one is installed. Twenty-eight segments, 1,270 feet of pipeline will be upgraded with this technique due to the age, condition and/or location of the pipeline.
UV Cured In-Place Liner
Most of the project, 31 segments totaling 6,858 feet of pipeline will be upgraded with this non-invasive process. The cured in-place method replaces damaged or deteriorated sewer pipe without digging up the existing pipe or disrupting roads, driveways, sidewalks, or landscaping.
The process involves installing a resin-saturated felt tube into an existing sewer pipe. Once in place, the tube is inflated to fit tightly inside the original pipe and cured using ultraviolet light to create a new plastic pipe within the old pipe.
Glue Like Odor
On occasion, there may be a “glue like” odor during the curing process that arises from the resin (Styrene) used. Once the pipeline is fully cured, the odor will be eliminated. If you detect an odor in your home, it is likely entering through the pipe that connects your home to the public sewer main. A “U” shaped pipe called a P-trap is located at all drains/plumbing fixtures and is designed to keep sewer gas and other vapors out of your home or building. Floor drains/plumbing fixtures may dry out at the P-trap and allow sewer vapors to enter your home or building.
About the Resin
Styrene is a clear, colorless liquid that is synthesized for commercial use from petroleum and natural gas byproducts.
Styrene also occurs naturally in the environment and is an inherent component in small concentrations of many commonly consumed foods and beverages, such as coffee, strawberries, and cinnamon.
For the general population in normal circumstances, measured environmental styrene concentrations from curing in-place in the air are at levels too low to cause health effects.
Since 1971, this curing in-place method has been used to safely reduce construction time, cost and disruptions in sewer service, while minimizing the impact on homes, businesses, traffic, and the environment.
Prevent/Eliminate Odor
Pour ½ gallon of water in all plumbing fixtures and drains to fill your P-traps prior to the start of the project. If you smell the odor in your home, ventilate the area by opening windows and doors. Adding more water to the P-traps and using a fan may help eliminate the smell faster. If the odor persists after
ventilating, contact the Santa Margarita Water District at 949/459-6420.
