Providing treatment solutions for noncompliant camp system

Problem: Stony Glen Christian Camp in Madison, Ohio, had an NPDES treatment system that was in noncompliance, and septic odors were a persistent nuisance. The Ohio Environmental Protection Agency required an equipment upgrade. Goals included low maintenance and operating cost, with the ability to handle variable hydraulic flows of 500 to over 4,000 gpd combined domestic and kitchen waste, with NH3 reduction from levels of 140 mg/L, treatment equipment in two locations, and meeting NPDES performance limits.

Solution: Existing septic tanks were converted into biological reactors for first-stage primary treatment, using IMETTM bioreactors for high strength and NH3 reduction. Influent alkalinity was increased to aid in NH3 reduction using Anua Puralinity modules. Time-dosed pump stations transfer treated effluent to 36 Anua Puraflo peat fiber biofilters. The center camp system required 28 Puraflo modules and the A-frame camp system required eight Puraflo modules for peak-season hydraulic loading. Secondary treatment is provided by surface sand filtration, re-aeration and UV disinfection through Salcor 3G units. Programmable control panels and Ethernet/IP connections allow use of SCADA for remote management.

Result: System design requirements were fully achieved, and along with other facility improvements provide an environment for year-round camping and retreat opportunities for participating churches. 336/547-9338;

GSF system a fit for narrow lot

Problem: An addition to a lakeside cottage on Lake Huron in Sanilac County, Michigan, resulted in the need for a new septic system. There was limited space on the already narrow lot, which was made narrower by a driveway and existing shed. A treatment system was needed in order to fit into the site’s constraints, that in addition to the lot size included heavy soils and a seasonal high water table 18 inches below grade.

Solution: Weiss Excavating installed a 450 gpd Eljen GSF system. Milan Supply delivered the units and provided design guidance. The system is comprised of a bed of 20 B43 GSF units, split into two rows. The GSF system was elevated due to the seasonal high water table, but was able to go in shallower than a traditional system because of its effluent treatment levels. After the units were installed on a base of stabilized ASTM C33 sand, pressure laterals were inserted into the 4-inch SDR 35 pipes on top of the units to provide timed dosing.

Result: The installation was quickly and easily completed. The system provides a low-maintenance treatment option for sites, and is tested and certified to NSF Standard 40. 800/444-1359;

Low-pressure system installed on limited-absorption property

Problem: A Lake Wylie, South Carolina, vacation home with a 1,000-gallon septic tank sat atop a former gravel pit where the ground had limited absorption for lateral discharge, with solids buildup that required frequent clean-outs. Adding a conventional grinder pump reduced the volume of solids, but also concentrated hydrogen sulfide gas in the wastewater. The acidic gas ruined the original pump in four years. Although replaced under warranty, a replacement pump ran until out of warranty and cost the homeowner a substantial amount for a replacement, which soon began emitting bearing noise.

Solution: A Flygt Low Pressure Sewage System (LPSS) was recommended. The pre-engineered system can serve individual homes or small residential developments. It consists of a fiberglass-reinforced polyester wet well with either a durable progressive cavity or centrifugal grinder pump. The impeller’s hardened cutting rings reduce solids to less than 1/3 by 5/8 inch in the slurry. The package comes with a level indicator, panel display, alarm and waterproof control box isolated from possible sump flooding.

Result: The LPSS installed easily and offered a lasting solution to the homeowner’s problem. 704/409-9700;

Advanced treatment system donated for Arizona home

Problem: A Yuma County, Arizona, resident applied and received a placement permit for a mobile home. It was discovered that the current septic system for the new home was an illegal cesspool and needed to be replaced. The new resident did not have the funds to replace the cesspool.

Solution: The local sanitarian, Rick Stacks, reached out to local businesses for help in getting the Yuma resident a legitimate septic system. They chose a three-bedroom-sized Advanced Enviro-Septic system donated by Presby Environmental, which treats the wastewater passively and disperses back into the earth without electricity.

Result: The resident’s mobile home now has a legal septic system that provides NSF 40 standard treatment. 800/473-5298;
