Traditionally, LPS systems have been used to provide central sewer service to areas where gravity sewer could not be installed, or the cost to do so was prohibitive. Now, LPS systems are gaining growing widespread acceptance in providing a viable and cost-effective alternative for renewal of failed gravity collection sewers and to address problems associated with wet weather events.
