Excellence in Management Recognition Program Criteria

Program Descriptions

The Littleton/Englewood Wastewater Treatment Plant (L/E WWTP) is committed to management excellence. The following paragraphs illustrate a portion of the program criteria required for this application.

Development and on-going implementation of a long-term facilities plan

In 1988, the L/E WWTP developed and implemented a long-range master plan, updated in 1994. A new master plan, termed a “Wastewater Utility Plan” (WUP), was completed September 2002 to guide the wastewater treatment plant and 22 connected sanitation districts through the year 2020. The plan addresses service area growth, planning/mapping, population/employment projections, watershed/water quality issues, environmental assessments, facilities consolidation, wastewater reuse, inflow/infiltration, wastewater flow/load projections, facilities design, sizing and staging, collection system infrastructure planning and management structures/financial planning. The plan also provides the basis for facilities permitting and overall guidance for the on-going L/E WWTP expansion to 50 mgd, as well as for district annexations and growth. The WUP was developed through input and coordination with neighboring wastewater service providers and is incorporated into the Denver Regional Council of Governments (DRCOG) “Clean Water Plan” to proactively address regional planning.

Asset Management

A comprehensive approach to asset management integrates the annual cycle of budget planning with maintaining equipment conditions necessary to meet the requirements of the facility. Infrastructure replacement costs, based on a 20-year cycle, are included in the annual budget.

Equipment failure analysis reduces the impact of equipment breakdown, allowing resources to be used to identify equipment problems and maintain reliable equipment condition. By using techniques such as failure prediction, equipment history is used to identify time-based failures. In addition to failure prediction, over 2,100 individual preventive maintenance items are completed each year. Through these practices, and by clearly identifying roles and responsibilities, setting expectations and coaching to meet performance objectives, the maintenance staff provides a work management environment that is enhanced.

Reductions in the cost or usage of chemicals and utilities

The L/E WWTP participates in the Multiple Assembly of Procurement Officials (MAPO) for bulk chemical purchasing. Through this purchasing cooperative, Colorado front-range municipalities pool their chemical needs into a bid package more beneficial to the group.

Workforce related initiatives

Safety is a major management objective at the L/E WWTP. Long term commitment to safety and safety awareness has resulted in a significant reduction in lost-time accidents. From 1985-1992, an average of 5.5 lost time accidents per year were recorded. From 1993-2002, an average of 1.7 lost-time accidents per year were recorded.

Facility automation or other technological applications

Over the last three years, the L/E WWTP has worked progressively to provide an electronic information infrastructure. This initiative merges the selection and implementation of a Laboratory Information Management System (LIMS) with a Plant Operations Data Solution (PODS). These programs integrate information from the laboratory, real-time data from field instrumentation and staff recorded data. A wireless Ethernet component was also installed to provide access to Local Area Network (LAN) resources for plant staff working in the field.

The wireless project was pilot tested to allow access by staff in the field to the plant Intranet. Remote Intranet access provides entry to: Standard Operating Procedures (SOP), Computerized Maintenance Management System (CMMS) for procedures, inventory, time and comment input, Internet access to vendor sites for manuals, assembly diagrams, parts lists, and parts availability and Computer Aided Design (CAD) drawings of all recent plant construction and recorded modifications (E-Mail too!), allowing more productive repair efforts.

Concurrent with the development of the LIMS project, the wireless application was extended campus-wide for use with a wireless barcode identification system. The system is designed to record information pertaining to the individual collecting the sample, sample location and the actual sample for chain-of-custody and time-stamp requirements.

The PODS use of this wireless system will eventually be developed to include manually collected field data and comments from Plant Operators on electronic “data sheets.” Data will be cached until verified by a supervisor and then exported to the PODS database.

Watershed based activities – cite specific activities and provide examples:

The L/E WWTP partners with numerous entities and organizations to address water quality and watershed issues. The following is a summary of a few of the larger watershed/water quality organizations in which the L/E WWTP is involved:

• Participate with the DRCOG Water and Environmental Planning Committee which addresses Denver metropolitan watershed/water quality issues.

• Member of the Colorado Water Quality Forum currently addressing 10 statewide issues.

• Participate with the South Platte Coalition for Urban River Evaluation (SPCURE), a watershed group addressing South Platte River water quality/monitoring, and TMDL development. The group recently developed and submitted a draft nitrate TMDL for State approval.

• Participate with the “Impacted Water Supply Workgroup”, a committee investigating impacts to drinking water supplies caused by urban runoff, wastewater treatment plant discharge, agricultural runoff and other non-point sources.

• Participate with the Barr/Milton Lakes stakeholders group to address downstream lake eutrophication concerns.

• Participate with the Nutrient Criteria Workgroup to proactively implement nutrient regulations for rivers, streams and lakes in Colorado.

Resource conservation activities

Electrical co-generation utilizes biogas produced from anaerobic digestion. Heat is recovered from the engines to maintain digester temperatures and provide hot water for building heat. Electricity generated saved approximately $358,000 from utility bills over the past 3½ years.
