ET24SWE0038 - Water and Wastewater Pump Replacement Industry Standard Practice & Measure Package Update
The existing SWWP004-03 Water Pump Upgrade Measure Package has been approved through 12/31/2024, but the California Public Utilities commission (CPUC) has mandated that this Measure Package (MP) cannot continue beyond 2024 without a Market-Based Industry Standard Practice (ISP) Study compliant with the latest CPUC ISP Guidance v3.1 (CPUC Energy Division (file.ac)). Several programs utilize this MP and will benefit from the renewal of the MP past 2024. Additionally, the existing MP only includes pumps for clean water use, yet similar pump types are utilized in wastewater applications and undergo the same rigor of testing for Pump Energy Index (PEI) ratings. Hence, there is a pressing need for a similar MP to be developed for wastewater pumps to drive high efficiency pump adoption in the wastewater market segment. A previous CalNEXT ET study (ET23SWE0039: Wastewater Pump Measure Development) also recommended the creation of a deemed MP for wastewater pumps to address this market gap.
This project will perform a Market-Based ISP Study for clean water pumps and will update the existing MP SWWHP004-03 with the appropriate industry-standard PEI. This project will create a new MP for wastewater pumps or modify the existing MP to include wastewater pumps leveraging the previous CalNEXT study.
The SWWP004-03 Measure Package currently applies to clean water pumps, but similar pump types are also used in wastewater applications. Wastewater pumps meeting secondary treatment standards or cleared of solids undergo the same Pump Energy Index (PEI) testing as clean water pumps, yet no measure package addresses their efficiency. A previous CalNEXT study identified this gap, recommending a deemed measure package for wastewater pumps. To address this, a market study was conducted to establish baseline PEI values for both clean water and wastewater pumps. Surveys targeting diverse stakeholders revealed limited awareness of PEI ratings, with pump reliability and cost being the primary purchase drivers. Sales data from the Northwest Energy Efficiency Alliance (NEEA) highlighted average PEIs ranking at the 76th percentile of the DOE database, suggesting incentive program influence. There was no indication of differing PEI ratings between clean water and wastewater pumps. Recommendations include updating baseline PEI values in the SWWP004 Measure Package using the 25th percentile of DOE data for each pump size and control strategy to encourage adoption of efficient pumps in both markets.
