Request for Proposals
The Water Environment Federation (WEF) is inviting proposals for the provision of automatic samplers, automatic sampler training, and automatic sampler troubleshooting to small wastewater utilities as part of our activities under our Cooperative Agreement with the US Centers for Disease Control and Prevention (CDC).
During the current COVID-19 pandemic, wastewater-based disease surveillance has emerged as a tool for understanding COVID-19 infection trends in communities independent of healthcare-seeking behavior and clinical testing resources. Participation in wastewater surveillance to date, however, has skewed toward larger, well-resourced utilities. These resources include but are not limited to continuous in-situ monitors and automatic samplers.
Automatic samplers (also known as composite samplers or peristaltic samplers and hereinafter referred to as “autosamplers”) can collect up to 24 distinct samples before they must be restocked with empty bottles. They can be programmed to collect samples at specific time intervals or at specific flow rates. Autosamplers facilitate collection of representative wastewater samples for disease surveillance, but also can enable improved understanding of organic, solids, and nutrient loadings to wastewater treatment facilities. By providing new autosamplers to at least 225 small utilities, this project aims to increase participation in wastewater surveillance by smaller, rural, and tribal communities and, therefore, expand access to this effective public health surveillance tool.
Small utilities will apply to receive an autosampler as part of this program and will indicate their preference for either a full-size, refrigerated sampler that can be used to collect a sample where power is available (such as in a pumping station or at the influent to a treatment facility) or portable, compact autosampler that could be deployed in locations without available power (such as a manhole). In addition, utilities selecting a full-size sampler may opt for either a standard model or a model suitable for operation in cold ambient temperatures, as described for Task 1 below. While at least 225 utilities will be supplied with an autosampler as part of this program, the total number of participating utilities (and therefore autosamplers provided) may exceed 225 depending on demand and available budget. Through this request, WEF is soliciting proposals from contractors for the provision of autosampler packages, and training and troubleshooting related to their use.
Please see the RFP for additional detail for submissions.
