Additional Operating Experience
Waste Water Treatment
Energy Answers has experience with managing large metropolitan systems down to small community operations.
From 2002 until 2005, Energy Answers staff operated the Anguilla (St. Croix)Waste Water Treatment Plant under contract to the Government of the U.S. Virgin Islands to comply with all the government mandates. This plant was under an EPA Consent Order and had a long list of operational problems. Energy Answers' staff was able to get the plant functioning in a reliable manner, processing up to 4 million gallons of waste water per day, eliminating the discharge of raw sewage into the Caribbean.
Additionally, the 3 major waste water pump stations on the island of St. Croix were repaired, upgraded, and contract-operated by Energy Answers from early-2004 until mid-2005. The pump stations transfer the sewage from locations throughout the island to the Anguilla Plant. These pumping stations had major operational problems and were in need of new equipment, as well as a strong maintenance and operation plan. These plants were brought into compliance while under Energy Answers’ management.
Energy Answers is a proponent and advocate of alternative natural treatment systems for wastewater. These systems eliminate discharges to waterways, and recover for reuse the solids and effluent from these natural systems known as sub-surface constructed wetlands.
In 1999, Energy Answers supported the development of an in-vessel composting facility designed to accept food and yard waste, clean wood, and non-recyclable paper products generated by produce markets, grocery stores, colleges, restaurants, and hotels in the Albany (NY) area. These materials were processed in an enclosed 50 ton per day Wright Environmental in-vessel composting system that facilitated their rapid breakdown, minimized odors and produced a high-quality landscaping material.
Loads of organic-rich materials were received in an enclosed tipping area and conveyed into a mixer. After thorough blending, the material was conveyed to one of two Wright Environmental composting tunnels. Each of the composting tunnels was designed to accommodate 25 tons per day of food wastes amended with paper and wood, with 14 days retention within the tunnel. The output was then screened and stored in windrows on a curing pad for 45-60 days. The windrows were turned as needed to keep the composting process active.
In 1993, Energy Answers joined with another recycling firm to provide communities and businesses in the SEMASS service area with an outlet for the material that they were collecting through their recycling programs. The project started by “recycling” an abandoned 34,000 square foot ice skating rink into the home for the new facility. The West Bridgewater MRF utilized a magnet to extract the steel cans and other ferrous metals from the recyclables and an air classifier to separate the plastic and aluminum from the glass. The recovered metals, plastics and paper were baled for transport to their individual markets.
The numerous communities served by SEMASS collected only a small quantity of recyclable materials, making it extremely difficult for the various communities to effectively market their materials and create viable recycling programs. Energy Answers provided assistance to these communities by developing a regional facility serving private waste haulers in southeastern Massachusetts, guaranteeing acceptance of the recyclable materials they collected, and effectively negotiating with scrap dealers and recyclable materials markets to help these small programs succeed.
