<br />Task 4 — Sedaru Smart Ops Software & Implementation (FY2016 -17)
<br />The City operates a pressurized water system, with limited gravity storage facilities, and a
<br />combination of variable frequency drive and solid state pumps. This hydraulic profile Induces
<br />frequent in- fighting between pumps and pump controls, causing pumps to over -cycle and over -
<br />pump, which results in high operational costs associated with pumping energy. The City would
<br />like to increase its operational awareness, and understanding of how better to manage pump
<br />operations to reduce pump energy costs.
<br />1. Program Operational Schema: IDM will work with the City to understand City operator's
<br />current operating strategies, as well as the equipment, SCADA logic, set points, and typical
<br />operating conditions associated with the City's system, wells and pumping plants.
<br />2. Update Computer Modeling with Automations: IDM will utilize the hydraulic computer
<br />model delivered in the Water System Computer Modeling project to add functionality to the
<br />system, which may Include: real -time hydraulic modeling, monitoring of existing water
<br />system facilities, automating alerts and notifications associated with predefined system
<br />demand and /or operating thresholds which may be associated with inefficient pumping or
<br />high energy costs, and providing pumping recommendations to water system operators
<br />which may serve to balance, reduce, or dampen system operations associated with water
<br />pumps over - cycling, over - pumping, or operating at inefficient points on theirsystem curves.
<br />3. Develop Automated Operator Recommendations: Recommendations will be automated in
<br />accordance to criteria developed with City operators and engineering staff to consider best
<br />operating practices, required customer service levels, and methods of operation to maintain
<br />water quality standards. Parameters will include pump operating costs, efficiencies, varying
<br />levels of water demand, including but not limited to maximum demand, minimum demand,
<br />conservation demand, and other operational conditions.
<br />Benefits: IDM estimates conservatively, that the City will experience 10 -20% reduction in pump
<br />energy expenses after the deployment of this energy reduction technology,
<br />Recurring annual costs for software support and maintenance of Sedaru Smart Ops is $25,000,
<br />This includes costs to support up to 10 City users (engineers, operators, and management), and
<br />stakeholders of the system input and output, operating costs to maintain data and system
<br />integrations, and ongoing periodic updating of parameters to support latest operational criteria,
<br />system and facility costs to operate, efficiencies, and operating methodology.
<br />Task 5— Hydraulic Model Evaluations and Support (FY 2017 -18)
<br />IDM will provide support to City staff for GIS, hydraulic modeling, analysis, planning, application
<br />development, and training services on an as- needed basis and may include but are not limited
<br />to the following:
<br />• Services including but not limited to: Energy management, Operational Planning, Water
<br />Quality, CIP Prioritization, Asset Management, Criticality, etc.
<br />• Hydraulic model construction and updates
<br />• Software and application, implementation and integration
