New Treatment System

  • Options considered
  • Replacement of existing lagoons
  • Mechanical Plants

December 15, 2016 37

slide-38
SLIDE 38

Timbers Water and Sanitation District

Replacement of existing lagoons would require

  • Replacement and maintenance of the lower 3185 feet of

the collection system

  • Construction of 3 new lagoons
  • Haul away of waste material during construction
  • Renovation of discharge system
  • Acquisition of addition to land easement to include service

road and potentially enlarge spray irrigation field

Mechanical Treatment Plants

  • Two kinds
  • Sequencing Batch Reactor
  • Advantex Packed Bed Media Filtration System
  • Selected Fluidyne ISAM Sequence Batch Reactor
  • Many installations at our elevation or above, and in our climate
  • Tolerant of variable flows
  • Simple to operate
  • Many CDPHE approved installations
  • Small footprint: 14’ x 40’ tank, 24’ x 60’ foot building
  • Comparable acquisition and operating costs to alternatives
  • No odor
  • Minimal operating noise

Option proposed in PNA

  • Collection system: Gravity, upper system only
  • Treatment system: Fluidyne ISAM SBR at new upper site
  • Discharge system: surface to McKinnis Creek

How do we pay for the new system?

  • District has already approved taking on $2M in debt to

finance construction (May, 2014)

  • Financed by property taxes
  • Average annual increase per home/unit estimated at ~$1100 based on

current state loan terms

  • Actual increase dependent upon assessed value
  • Board has had meetings with state funding agencies
  • Board intends to seek balance of funding through state

grants

December 15, 2016 53

What happens next?

  • Intent:
  • Complete necessary permits, acquisition of land, and CDPHE

approval of final plans and funding applications in time to bid project for construction in summer 2018

  • If CDPHE approvals and funding allow, collection system

replacement could be done summer 2017

  • Immediate next steps
  • Completion of income survey
  • Permits, variances and land acquisition for upper site
  • CDPHE approval of PNA
  • Submission of funding application for engineering costs by April
