Wastewater Treatment Facility
On May 15, the Director of Public Works gave a presentation to the City Council and Public regarding a proposed new wastewater facility.    View the Presentation   Listen to Audio

On June 5, the City Council authorized a $17.63 (per unit) surcharge to be placed on all utility accounts.  This surcharge will go toward the construction of a new treatment facility.  The surcharge will go into effect on July 1, 2017. 

Current Facilities
The current wastewater treatment facilities were constructed in 1963 and upgraded in 1995 after the City received a Notice of Violation and Compliance Order from the SD Department of Environment and Natural Resources (SDDENR).  The DENR regulates all surface water and wastewater operations within the state.  We are also subject to EPA and other state and federal regulators. 

  • The current system is made up of three ponds consisting of Cell #1 (15.4 acres) which is 5' deep and provides aeration and removes 80% of the biochemical oxygen demand (BOD).
  • Cell #2 (39.6 acres) is 9' deep.
  • Cell #3 (26.6 acres).  At this point, waste is either suitable for discharge or irrigation (April 15 - October 15). 

All cells are located on city-owned property north of the Sturgis Brown High School.

In 2000 the City purchased the Sundstrom property and constructed a new pumping station, transfer line and Cell #4.   Cell #4 added 30 more acres of storage as well as 300 acres for irrigation.  This expansion was expected to handle additional needs for 20 years. 

DENR Permit
The City's most recent permit expired in March 2012.  We are in negotiations with DENR for a new permit, however, with current regulations, we will not be able to meet state requirements and upgrades will be needed.

Currently, we are only allowed to irrigate, we are not able to discharge into Bear Butte Creek. 

In 2014 and 2015 we had to conduct Emergency Discharges because we were at capacity. 

Current Status
  • At this time, we are not prepared for additional growth.
  • We are not meeting current regulations.
  • We have an aging infrastructure that has met its life expectancy.

Population Growth

If the population continues to grow at just 1% over the next 20 years, we will be at 7,000.  We are not prepared to handle this much use.  We want to be proactive and not wait for a major failure before we make necessary improvements.  

Regulations continue to be more strict and technology is available to keep up with these regulations. 

Sewer vs Infiltration
The wastewater treatment facility handles not only sewer waste, but also infiltration for numerous areas such as stormwater, drains, infiltration from damaged pipes, sump pumps, and infiltration from broken pipes.  This is why our slip line program is important.
As a rule, the wastewater gallons should be less than what is produced from our wells.  Ours is 2x that amount.  Per capita, we should each be producing approximately 100 gallons of wastewater per day, in Sturgis we each produce 140 gallons on average. 

More Stringent Regulations in the Near Future
Our neighboring states have much more stringent regulations which will be phased in for South Dakota as well.

If we do nothing to make improvements:
  • No capacity for new development
  • No control over irrigation disposal
  • Increased Emergency Discharges
  • Permit Violations - Fines $$$
  • Cell #1 filling up with solids (need to be cleaned and solids removed every 5 years)

Main Sewer Pipe from City to the Treatment Facility
Problems with the main pipe:
  • Under Capacity
  • Was constructed as an emergency installation
  • Poorly graded
  • Buried too shallow

This will also need to be addressed and corrected. 

Options Moving Forward
Working with AE2S three solutions were identified.
  • SAGR
  • Membrane Bioreactor (MBR)
  • Activated Sludge system  

Moving forward, the recommendation of a new an MBR system is the best overall fit for the City. This type of system is expandable, the most efficient, it has the ability to meet future regulations and has a smaller footprint size. 

Funding this Project
This project is estimated to cost $16,647,000 (includes slip lining, new main line, Cell #1 solids removal, MBR)

State Revolving Loan Fund Package

Clean Water SRF Loan (2.5% for 30 years)  $16,247,000
Principal Forgiveness (max 9.9%)  -$1,600,000
Consolidated Grant -$400,000

Loan Balance $14,247,000 for entire package.  This funding package requires the City to have a dedicated funding source for the repayment.  This is provided by enacting a surcharge.
