Project Summary

Coleman Engineering was retained by Caritas Corporation to provide consulting services related to all compliance issues with the existing drinking water system. The mobile home park owns and operates a small surface water treatment plant and drinking water distribution system. This system was in place when current park owners purchased the property. Coleman Engineering was engaged to assist the new owners in maintaining compliance with state and federal regulations. Services included preparation of a complete TMF report, application for new operating permit, and preparation of a compliance plan detailing the addition of turbidimeters on each of the pressure filters.

The Project eventually evolved to include design of new potable water pipeline, fire-flow pipeline, and connection to existing Placer County Water Agency potable water main to service 212 residential mobile home park units. Coleman was responsible for coordinating project funding from the Drinking Water State Revolving Loan Fund, FAAST application and design of over 2,800 feet of pipe alignment including existing utility conflicts, connections at existing pipelines, landscape removal and replacement costs, hydraulic calculations, project cost estimates, and plan drafting. Construction was completed in 2021.
