System Evaluation and Capacity Assurance Plan (SECAP)
Adopted February 6, 2020
The purpose of the South Placer Municipal Utility District Wastewater Collection System Evaluation and Capacity Assurance Plan (SECAP) is to provide the District guidance in its efforts to assure capacity for existing customers and information on how to prepare and plan for future development. This document summarizes the District’s compliance with provision D.13.viii – System Evaluation and Capacity Assurance Plan of the California State Water Resources Control Board (SWRCB) Order No. 2006-0003-DWQ, the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (SSS WDR). It is included by reference to the District’s Sewer System Management Plan (SSMP); is reviewed annually; and is updated as deemed necessary by District staff (at minimum every five years) to account for conditions affecting collection system capacity.
The specific objectives of this SECAP include:
- Comply with requirements of the California State Water Resources Control Board Order No. 2006-0003-DWQ, the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (SSS WDR) and the District’s SSMP to evaluate hydraulic deficiencies, establish and implement design criteria (i.e., design storm), establish short-term and long-term capital improvement projects to address system deficiencies, and develop a schedule of completion dates for the planned capital improvements projects.
- Evaluate the capacity of the collection system under various scenarios (i.e., existing dry weather, existing wet weather, near-term wet weather, and long-term wet weather conditions) to identify capacity deficiencies and assign capital improvements projects for each scenario.
- Utilize the results of this SECAP to identify, quantify and prioritize the recommended capital improvements and the associated impacts on participation charges.
