Browns Valley Trunk Project

 

 
 

What is the Browns Valley Trunk Project?

 
Wastewater from the Browns Valley area and Southwest Napa currently flows through the sewer pipelines to the West Napa Pump Station on its way to the treatment plant.  The Browns Valley Trunk Project is designed to intercept this wastewater and divert the flow away from sewer lines that are over capacity  via a new pipeline that will deliver the wastewater to NapaSan for treatment.  

  

Why is this project necessary? 

 
The sewer pipes in Southwest Napa are over capacity in many areas, meaning that these pipes are in danger of overflowing when there are high flow events, such as a large storm.  Sewer overflows can result in untreated sewage getting into storm drains and flowing to creeks or the river, which is bad for both human and environmental health.  

 The Browns Valley Trunk project is designed to divert flow from sewer lines that are over capacity.  In the map on the left below, red lines show sewers that can overflow during large storm events.  The map on the right shows the project’s proposed alignment (yellow) as well as the reduction in pipes that can overflow – the number of overcapacity pipes (red) significantly reduces from this project.
