In 2014 the City retained the services of Hazen and Sawyer to build a hydraulic model of its water distribution system. The model includes all City-owned water mains in Henderson County as well as in the Town of Laurel Park.
Hazen and Sawyer recently completed a Water System Master Plan project that used a new model to plan capital improvement projects to the year 2040, in order to eliminate existing deficiencies and supply water to projected growth areas. Two versions of this plan are provided below - one with larger figures and one without.
In 2017 and 2018, Black & Veatch worked with the City of Hendersonville to perform its Sanitary Sewer Asset Inventory and Assessment, which will serve as the City's sanitary sewer master plan document. The master plan provides a roadmap to maintain, improve, and expand its collection system so that the City can operate a great utility for all its current and future customers. The Sanitary Sewer Asset Inventory and Assessment includes a condition assessment of the sewer collection system, development and calibration of a dynamic hydraulic model, flow projections from the service area through 2040, hydraulic capacity assessment of the sewer system, and finally, the development of a risk-based, prioritized capital improvement program (CIP).
