Project Overview
Within the overall umbrella of sanitary sewer evaluation and rehabilitation is the essential management of private property infiltration and inflow (PPII) improvements. Infiltration refers to groundwater seeping into the sanitary sewer system through defects in sanitary sewer pipes. Conversely, inflow is the entry of clear water (distinct from sewage wastewater) into the system through direct connections such as downspouts from roof drains, foundation drain connections, and cross connections with storm drains.
Homeowners are responsible for certain property improvements and must agree to share a portion of the associated costs. These improvements can encompass a range of services including the replacement of private lead service water lines, installation of sump pumps, storm laterals, and rehabilitation of sanitary sewer laterals. The latter may involve advanced techniques such as pipe bursting or cured-in-place pipe (CIPP) lining.
Approximately 70 residences in West Allis have benefited from raSmith’s home inspection services in 2024. raSmith conducted inspection services for 80 homes in 2022 and 75 homes in 2021. In 2021 and 2022, the program included foundation drain disconnection, sump pump installation, and storm lateral connections as part of the program.
A significant challenge successfully handled by raSmith was the continuous coordination required among the owner, contractors, and homeowners. The raSmith team prioritized keeping residents well-informed and involved throughout the construction occurring on their properties, which was crucial for the project’s success. Additionally, raSmith’s responsibilities extended to a comprehensive coordination of building inspections, providing engineering design services to address emerging challenges during construction, ensuring quality assurance and control, compiling daily inspection reports, and determining installed construction quantities.
