The pressure is on for low-pressure sewers

When small communities experience population growth, there is tremendous pressure on the local decision-makers to improve the infrastructure. Whether it is the schools, the roads, or the utilities, these improvements come at a significant cost. If continued growth is desirable, then a small community may consider installing a sewer system so that more housing units can be placed on smaller land parcels. Wastewater collection is the most expensive component of developing a sanitary sewer system and community leaders need comparative economic information in order to decide which style of collection system is best for their community. This report introduces a revised spreadsheet-based model that can provide cost estimations for low-pressure, effluent, vacuum, and gravity sewer systems. Originally created in 2009 with a grant from the WERF, this model has been updated for 2018 construction costs.
