Please include the following item on the City Commission consent agenda for consideration at the June 12, 2007 meeting.

Renew contract with Marsh McBirney, a Hach Company for Sanitary Sewer Collection System Flow Monitoring- Data Delivery Services

Sanitary Sewer Collection System Flow Monitoring-Data Delivery Services:

This is a miscellaneous capital improvement project from the 2003 Wastewater Master Plan and is identified to provide improved data for monitoring and modeling of sanitary sewer collection system and capacity.

Project History:

The Utilities Department solicited and received proposals from qualified vendors for permanent flow monitoring services in January of 2006. Marsh McBirney, a Hach Company and ADS Environmental Services responded. Staff evaluated the relative offerings and negotiated a data services agreement with Marsh McBirney, a Hach Company based on costs and services meeting specification and proposal requirements.

Project Status:

Staff identified 27 permanent flow-metering locations and 8 area rain gauge locations within the collection system that provide detailed information corresponding with Wade and Associate’s Pipedream sanitary sewer model. Marsh McBirney/Hach installed 27 flow meters and 8 rain gauges in October 2007. Another 3 locations were added to bring the total installed flow meters to 30. A secured internet server was setup so that information was monitored in real time operationally and provides detailed and near continuous information regarding sewer capacity utilization. This information is used to efficiently target maintenance activities, provide more accurate sewer capacity information to prospective developers, land owners and engineers, as well as identify and prioritize capital improvement projects. Marsh McBirney/Hach has provided outstanding services and data delivery.

The contract is for a period of one year and renewable annually.

Project Funding:

Funding will come from the Utilities non-bonded construction fund.

Action Request:

Utility Department staff requests approval from the City Commission to authorize the City Manager to execute the annual renewable contract agreement with Marsh McBirney, a Hach Company for Sanitary Sewer Collection System Flow Monitoring-Data Delivery Services totaling $210,000
