A Lakefront Estate Requires an Onsite Technology Upgrade

Dervin Witmer got a call from a friend who built a house. He needed help. Witmer owns Dig-It Excavating in Cassopolis, Michigan, in the southwestern corner of the state, and his friend needed different wastewater options for the house.

The project involved tearing down an old cottage and building a new, larger, four-season home on a lot right beside a lake. The owners had two goals for their wastewater system.

The Hydro-Kinetic Model 600 FEU (flow equalized upflow) wastewater treatment system from Norweco has been NSF Standard 40 and 245 certified. The residential wastewater treatment system passed two consecutive back-to-back tests without performing routine maintenance for 12 months.

During the 12-month testing period, the system achieved effluent results of 2.0 mg/L CBOD, 2.0 mg/L TSS and 7.9 mg/L Total Nitrogen. The effluent quality is ideal for installations where exceptional treatment and field sampling are mandated by regulation.

Flow equalized liquid from the clarifier enters the Hydro-Kinetic filter where it flows downward and is evenly distributed beneath filtration media. The liquid then travels through the proprietary attached growth filtration media where the final treatment takes place. The non-mechanical flow equalization device guarantees all incoming wastewater is fully treated, regardless of heavy use periods.

The system includes a Model A100 air pump, which maximizes operational efficiency and increases service life. Multiple air pump mounting locations are available. The Model SD103 recirculation pump features a 1/3 hp electric motor securely mounted in an oil-filled, watertight, corrosion-resistant housing with lubricated ball bearings to assure long life. The pump features a 2-inch discharge connection.

The Singulair Green aerobic wastewater treatment system from Norweco Inc. features a light, versatile high-density polyethylene septic tank that’s suitable for installation applications where traditional tanks cannot be used.

“These tanks do not require specialized equipment, like a boom crane, to install and deliver, because the unit weighs just less than 1,000 pounds,” says Mike Benton, sales manager for Norwalk, Ohio-based Norweco. “All an installer needs is a utility trailer big enough to haul the tank and a mini-excavator. It’s a great tool for opening up new markets for installers.”

These systems treat greywater on-site, providing an additional source of water for restricted indoor use and reducing the strain on municipal resources.  Four international plumbing and building codes have adopted the NSF/ANSI 350 standard for water reuse systems, NSF International said in a press release.

The global public health organization developed NSF/ANSI 350: Onsite Residential and Commercial Water Reuse Treatment to standardize the material, design and performance criteria for water reuse systems.
