Dickerson Lake

Derby Lake Nevins Lake

Dickerson Lake

► Issue: DLAA concerns with aging septic systems and

regulatory standards for replacement, lake water quality and weed control, and drinking water well protection.

Dickerson Lake

► Solution: Surface water quality protection, drinking

water quality protection, and space/soil limitations for septic field installations can all be addressed with public sewer.

Feasibility Study

► DLAA contacted Spicer Group in April 2017 ► Feasibility Study scope of work: ▪ Meet and discuss proposed service district limits, growth potential, land availability, and regionalization. ▪ Calculate population and flow projections, and generate conceptual land size requirements. ▪ Evaluate alternatives and generate conceptual estimates of cost. ▪ Evaluate financing options - State Revolving Fund Loan, USDA Rural Development, and conventional bonding. ▪ Provide a written summary report of the above. ▪ USDA Rural Development pre-application ▪ Present the results at a public meeting for the purpose of obtaining resident’s signatures on a petition of interest for pursuing a project.

Today

Feasibility Study, cont.

► Potential Service District (pending Twp apprv) ► Estimated flows (Sidney data, pending EGLE apprv) ► How to collect and how/where to treat

Collection System Options

► Gravity Sewer ► Vacuum ► Low-pressure pumping

▪ Grinder Pump System ▪ STEP System

► Recommendation: Grinder Pump System

Treatment System Options

► Build a stabilization lagoon

▪ Surface water or groundwater discharge

► Build a mechanical treatment plant

▪ Surface water or groundwater discharge

► Regionalization

▪ City of Stanton ▪ Sidney Township

► Recommendation: Connect to Sidney Twp

Dickerson Sewer System

►

New collection system to replace aging septic systems

►

Estimated 175 grinder pump stations now, 6 future

►

Estimated 19,750 ft of collection system forcemain

►

1 main pump station with estimated 17,000 ft of forcemain

►

Connection to existing Lakeside Pump Station at Derby

►

Shared pumping to lagoon, shared treatment and disposal at lagoon

Summary of Alternatives

Financing

► Federal USDA Rural Development

▪ Pre-Application submittal – 45% Grant Eligible

► State Revolving Loan Fund (SRF) ► Conventional Bonds ► Summary, based on 181 connections:

Private Construction Costs

► Public construction consists of mainline

sewers, main pump station, service leads up to and including grinder pump stations.

▪ Each service lead and grinder pump needs easement from homeowner.

► Private work is outside of right-of-way and

easements, such minimum 100A power panel, dedicated 30A breaker, connecting home’s plumbing and electrical to grinder pump, abandonment of septic system.

Summary of Recommendation

► A public sanitary sewer system will eliminate the direct

connection pollution sources affecting the lake quality and will protect drinking water well quality.

► Recommended alternative is based on the 20-year present

worth analysis, the lowest estimated O&M costs, it is consistent with Sidney Township’s existing system, and their

• perator is willing to provide your O&M services.

► Recommended USDA RD funding includes grant. ► Estimated loan assessment of $18,400/REU is comparable to

septic system installation and comes with 40-yr financing.

► Next Step: Dickerson Lake residents to petition both

Townships to pursue a project.

Overall Project Process

► Petition Approval ► Township Approvals and Resolution to

County to Finance
