Leachate Treatment

Leachate Management

• Until 1994, direct discharge to POTW, up to 100,000 gpd

• Treatment process: Trickling Filters

• Discontinued after leachate implicated process upset

• SIU permit still current, but air-gap connection in place

• Disposal to regional treatment facilities by tankers

• Disposal cost increased over the years: $0.08/gal


• 10,350 trucks, approx. 30 trucks per day

• 67.3 million gallons, equiv. 184,000 gpd

• $4.76 million, $13,000 per day

Feasibility Study (2010)

• Existing practice is not sustainable

• Tasked to evaluate all options:

1. Disposal to regional POTW via tanker trucks

2. Treatment, onsite effluent discharge

3. Pre-treatment, effluent discharge to POTW via sewer

• Recommendations

• Onsite pre-treatment, maximizes potential for cost savings

• ‘Conventional’ continuous flow processes

• Limited area available for treatment facility


COUNTY’S OBJECTIVES

Reduce Cost of Leachate Disposal

Treat Leachate On-Site

Eliminate/Reduce Truck Traffic

Design/Build/Operate (DBO):

Partner with Industry Expert

Obtain Long-Term Pricing and Performance

Guarantees that are Financially Secured

Transfer Risk

PROCUREMENT PROCESS

RFP Issued Pursuant to New Jersey Wastewater

Treatment Public Private Contracting Act (the “Act”)

Act allows for procurement of aggregated services

and long-term contract with private company for

wastewater treatment services

Act also provides for selection on factors in addition

to price and allows negotiation

Material RFP Consideration (cont’d)

• Promote creativity, flexibility, and cost-competitiveness

• Demonstrated capability to meet performance criteria

• Permit-ability

• Prohibited Technologies

• Trickling Filters

• Sequential Batch Reactor (SBR)

• Powdered Activated Carbon Treatment (PACT)

• Aerated Lagoons
