Summary
The Hydraulic Modeling Rule, R309-511, requires Community Water Systems and Non-Transient Non-community Water systems to use hydraulic modeling to assure that new public drinking water projects will meet minimum flow and pressure requirements and not adversely affect new and existing water users. A summary of the rule’s requirements is provided in Hydraulic Modeling Rule Summary.
Forms
P.E. Designation for Compliance of System Hydraulic Model
This form documents the intent of a PWS to comply with R309-511-4(1)(a)(iii), which states that submission of the hydraulic model report is not required for projects where the water system maintains and updates a hydraulic model of the system and has designated a P.E. responsible for overseeing the hydraulic analysis in meeting the requirements of R309-511.
Hydraulic Analysis Certification for DDW Project
This certification should be signed by the P.E. who oversees a project’s hydraulic analysis. It also documents that the system’s designated P.E. concurs with the project’s hydraulic model.
Templates
Hydraulic Model Design Elements and System Capacity Expansion Report Template
This report template is for regional or system wide hydraulic analysis; for example, master plan or water projects that have significant impact on the water system’s capacity. This report requires detailed information of a water system’s capacity, ability to expand, and hydraulic modeling results.
Hydraulic Model Design Elements Report Template
This report template can be customized for hydraulic analysis of the drinking water projects. Typically, this template is suitable for project-specific hydraulic modeling analysis. It is not for regional or water system wide modeling.
