Project Profile: Twin Lakes Regional Sewer District

Learn how covalen helped improve the quality of life at this large lake community by replacing failing septic systems with a low pressure sewer solution.

Twin Lakes Regional Sewer District

Lake Freeman, 1,547 acres with 50 miles of shoreline

Lake Shaffer, 1,291 acres with 50 miles of shoreline

White County – Monticello, IN

PROJECT BACKGROUND AND CHALLENGES

Lake Freeman and Lake Shaffer are reservoirs on the Tippecanoe River, with housing and recreational developments along the shorelines. In the mid-1990’s, the two lakes were suffering from poor water quality due to failing septic systems and inadequate soil conditions. The poor water quality was threatening the area’s quality of life, safety, and economy. To combat the problem, the Twin Lakes Regional Sewer District’s Advisory Committee began seeking alternatives that provided optimal public health and safety, and that were cost-effective.

STRATEGIES AND RESULTS

After investigating numerous ways to provide sewer services to the large area around the lakes, the Advisory Committee decided that low pressure sewer systems and multiple wastewater treatment plants provided the best and most cost-effective solution to resolve the water quality issues. The septic systems along the lakes’ shoreline were eliminated. covalen provided much of the infrastructure required to implement to solution. The combination of E-One grinder pumps and directional boring enabled the project to be completed at an attractive budget. Directional boring traversed the lakes eight times and the Tippecanoe River three times. Using a staged implementation approach, eight service areas were defined and implementation began in 2000. Presently, 7,000 locations are served by 4,280 grinder pumps. When completed in 2012, the project will be the largest low pressure sewer system in North America.

SOLUTION COMPONENTS

  • 4,280 E-One grinder pumps
  • 180+ miles of directionally drilled HDPE pipe
  • 2 sewage booster packages
  • 5 Gorman-Rupp self priming lift stations
  • 4 wastewater treatment plants

KEY PROJECT FACTS

  • 7,000 locations
  • 4,280 grinder pumps
  • 180+ miles of directional boring
  • 4 wastewater treatment plants
  • Largest low pressure sewer system in North America

Project Profile: Kankakee Valley Schools

Learn how covalen helped develop an innovative approach to fulfilling this school’s HVAC requirements cost-effectively.

Kankakee Valley Schools

Kankakee Middle School, grades 7 -8, 555 students

Kankakee Valley High School, grades 9 – 12, 1,056 students

Wheatfield, IN

Winner:  2010 Indiana Governor’s Award for Environmental Excellence, Energy and Renewable Resources

PROJECT BACKGROUND AND CHALLENGES

In 2005, covalen provided a dedicated heat recovery system to upgrade the HVAC system for Kankakee Middle School. The cost-effective solution recycled the heat generated by the students, lights and computers and other electrical equipment in the school to reduce natural gas consumption. When it was time to remodel the Kankakee Valley High School, Kankakee Valley Schools was interested in a geothermal system, since the school was near the banks of the Kankakee River. However, the cost of a geothermal loop to fulfill all of the heating and cooling requirements of the school far exceeded the budget for an HVAC upgrade.

STRATEGIES AND RESULTS

Working with Tom Durkin, of Durkin & Villalta Partners Engineering, covalen provided an innovative approach to fulfill the HVAC requirements of Kankakee Valley High School. The solution married a dedicated heat recovery chiller system with a geothermal-based compression heater/chiller. However, the geothermal loop was designed to meet just 75% of the capacity requirements, saving capital outlays and operating expenses. Additional heating was provided by high efficiency condensing boilers and an additional chiller with air cooled heat rejection.  First year operational savings exceeded $112,000. Kankakee Valley High School realized a 26% reduction in utility costs.

SOLUTION COMPONENTS

  • 100 ton dedicated heat recovery chiller system
  • 150 ton geothermal-based compression heater/chiller
  • High efficiency condensing boilers
  • 200 ton chiller with air cooled heat rejection

KEY PROJECT FACTS

  • 26% reduction in utility costs
  • Increased heating & cooling capacity

Project Profile: Indianapolis Public School #87

Learn how covalen helped turn a liability into an asset with a creative approach for heating and cooling this school.

Indianapolis Public Schools

George Washington Carver Elementary School # 87

K-5, 225 Students, Year-Round Schedule

Indianapolis, IN

Winner: ASHRAE’s 2009 National Technology Award

PROJECT BACKGROUND AND CHALLENGES

When School 87 was constructed in 1935, an underground spring was found during excavation of the boiler room that required pumping to avoid flooding. To remove up to 150 gallons per minute of ground water, sump pumps were installed and ran continuously. Power outages disabled the pumps occasionally, which allowed the boiler room to flood causing damage to the boilers and mechanical equipment. The ground water was seen as a significant liability. In 2006, Indianapolis Public Schools adopted a year-round schedule for School 87, which necessitated the need for air conditioning.

STRATEGIES AND RESULTS

The transition to a year-round operation provided the opportunity to design a creative heating and cooling solution.  Working with Tom Durkin, of Durkin & Villalta Partners Engineering, covalen provided a geothermal solution that leveraged the ground water, turning it into an asset. School 87 has the lowest operational cost in the Indianapolis Public School System. Even with the addition of air conditioning and converting to a year-round operation, School 87 realized a 17% reduction in utility costs.

SOLUTION COMPONENTS

  • Verdetherm Systems heater/chiller
  • 120 ton geothermal heater/chiller
  • Geothermal water storage tank and circulating pump
  • Duplex two-pipe distribution pumps
  • Lead/lag plate and frame heat exchangers
  • Thompson Strainer pre-filters
  • Two 1,400,000 Btu Viessmann standby condensing boilers
  • Control logic
  • Submersible sump pumps and backup engine driven sump pump

KEY PROJECT FACTS

  • 17% reduction in utility costs
  • Increased heating & cooling capacity
  • Achieved backup/redundancy
  • Turned water liability into an asset
