Why are we doing this?
The existing 30-inch diameter Brookdale sewer main is nearing its capacity of 7 million gallons per day.
High amounts of hydrogen sulfide gas from naturally occurring bacteria have corroded the inside of the pipe.

8. Why are we doing this?
The existing pipe is located in an area affected by high groundwater levels. When groundwater makes its way into the sewer pipe, the space available to carry wastewater is reduced.
