The purpose of this Approval is to allow use of the System in Massachusetts to repair subsurface sewage disposal systems, on a Remedial Use basis. 2. With the necessary permits and approvals required by 310 CMR 15.000,this Approval for Remedial Use authorizes the use and installation of the System in Massachusetts. 3. The System may only be installed on facilities that meet the criteria of 310 CMR 15.284(2). The System is used to dispose of wastewater from an alternative system approved in accordance with 310 CMR 15.280 through 15.289 with effluent discharge concentrations that meet or exceed secondary treatment standards of 30 mg/L biochemical oxygen demand (BODS)and 30 mg/L total suspended solids(TSS). 4. This Approval for Remedial Use authorizes the use of the System where the local approving authority finds that the System is for upgrade of a failed, failing or nonconforming system and the design flow for the facility is less than 10,000 gallons per day(GPD). II. Design and Construction Standards Standards 1. The System, a subsurface drip distribution technology, is equivalent to a pressure distribution system designed in accordance with the Department's Pressure Distribution Guidance. In the event of conflict between the terms and conditions of this System's technology approval and Title 5,this approval shall control. 2. The System is a pressure distributed subsurface wastewater drip dispersal(disposal) system that replaces a soil absorption system(SAS)designed in accordance with 310 CMR 15.000. The System is designed to distribute effluent from an innovative treatment system and discharge it at a minimum depth of 6 inches below finished grade; it includes a pump, control panel, a filter module/hydraulic unit and drip dispersal zone(s). The dispersal zone includes small diameter flexible polyethylene tubing turbulent flow emitters regularly spaced inside the line. The System can be designed with either Classic turbulent flow emitters or with pressure compensating emitters typically located at one or two foot spacing within the tubing. The tubing is extruded with an inner lining of an anti-microbial agent to prevent bacterial growth. Dispersal field dosing is timed and controlled electronically to provide pre-programmed volumes of effluent for discharge to each dispersal zone. The System includes a return line that allows periodic flushing of the dispersal tubing. All drip zone supply and return pipes that are maintained filled with effluent after a pump cycle shall be buried below the frost line or properly insulated. All drip tubing and shallow manifolds shall be designed to drain into the soil or back to the pump chamber upon completion of the pump cycle. Each zone shall have air release valves at the high points of manifolds and check valves on each return manifold in multi-zone systems. The system shall be equipped with a totalizing flow meter. 3. The System may be installed in the A, B or C soil horizon or in fill material meeting the specifications at 310 CMR 15.255(3) at a minimum depth of 6 inches below the finished grade. 4. All access ports and manhole covers shall be installed and maintained at grade to allow for maintenance of the System. Remedial Use Approval—revised November 8,2018 Page 3 of 7 Geoflow Drip Dispersal System 5. The control panel including alarms and controls shall be mounted in a location always accessible to the System operator. 6. The System may be installed in soils with a percolation rate of up to 90 minutes per inch(MPI). The System shall not be installed in Class IV soils as defined in 310 CMR 15.243. 7. Effluent loading rates shall be as specified in 310 CMR 15.242(1)(a)and(b)with the exception of Class IV soils. 8. The System shall be designed and constructed with drip tubing with a spacing of 24 inches unless obstructions are encountered or in cases where more than the required tubing is provided and equally distributed within the approved appropriately sized subsurface disposal area in which case a minimum separation of 12 inches is allowed. As much as possible the System shall be designed to provide equal distribution across the designated disposal area. 9. The System does not require a five foot over dig as indicated at 310 CMR 15.255(5). 10. The System includes the following: a. Pumps capable of providing pressure of 10-45 psi throughout the dispersal zone(s). Each drip dispersal zone shall be dosed a minimum of six times per day, or as recommended by the Company. Duplex pumping shall be provided for facilities with design flows of 2000 gpd or greater. The pump chamber, combined with available storage in the pretreatment units, shall provide at least one-day storage as required by 310 CMR 15.231. b. Timed dosing for the drip system with a timer controller capable of operating the system during peak flow events without high-level alarms. c. A self cleaning filter capable of screening particles larger than 100 microns prior to discharge of the effluent to the drip tubing. Filter(s)backwash shall be conveyed back to the pump tank,a separate settling tank or to the septic tank. d. Air vents in a zone shall be placed at a higher elevation than the drip tubing in that zone but below the ground surface. Air vents shall be accessible from fmished grade and insulated to prevent freezing. e. Drip tubing lines installed as level as possible on contour and a minimum of 6 inches below finished grade. Drip line spacing is typically 24 inches with drip tubing emitters spaced 24 inches on center. More than the minimum length of tubing may be utilized within a properly sized soil absorption system. When the drip lines spacing is greater than 24 inches by 24 inches,the size of the dispersal field shall be increased to provide equal distribution with adequate tubing separation. All drip line flushwater shall be conveyed back to the pump tank, a separate settling tank or to septic tank. f. The effective effluent dispersal area is calculated using the total area of the drip tubing system including a one-foot addition on each side or two square feet per foot of drip tube when tubing is spaced two feet apart.No sidewall credit shall be given for this System. g. The dispersal area shall not be installed under a paved surface, or in areas of routine traffic,parking or storage of heavy equipment. In addition no planting or soil excavation shall be done in or within 5 feet of the drip disposal area after its installation. The system Remedial Use Approval—revised November 8,2018 Page 4 of 7 Geoflow Drip Dispersal System may be designed to allow for installation of drip tubing up to five feet from a building cellar wall. h. No change in existing surface slope over the dispersal field is required to comply with 310 CMR 15.240(10). 11. All System control units,valve boxes,drip dispersal lines,conveyance lines and other System appurtenances shall be designed and installed to prevent freezing per the Company's recommendations. 12. The System designer shall provide plans and specifications prepared in accordance with 310 CMR 15.220 for all proposed System installations to the approving authority with required standard details and installation instructions. 13. Drip tubing may be installed with a vibratory plow,a static plow,a narrow trencher(<6"width), by hand trenching,or by scarifying the surface and bedding the drip tubing in clean sand meeting the requirements for fill material in Title 5 at 310 CMR 15.255(3)with cover consisting of sand and topsoil meeting the 6 inch minimum depth requirement.Vegetative cover must be replaced for installations where it is removed or buried during installation. 14. Drip tubing shall not be installed when soils are frozen or saturated. 15. Prior to System start up,a clean water test of the System shall be performed in the presence of the Company's representative and the approving authority to check for leaks and to ascertain and verify system design flush and dose rates. 16. System unit malfunction and high water alarms shall each be connected to an independent power source from the operating pump(s)run from the main power source of the facility. 17. For Systems with a design flow of 2,000 gpd or greater,the System shall be equipped to provide a flow meter and automatic remote telemetric notification to the operation and maintenance (O&M)provider. 18. Installation of inspection ports is not required for this System. III. Allowable Soil Absorption System Design 1. Any reduction in System design sizing or setbacks shall be based on the MassDEP approved reduction allowed for the alternative treatment system that precedes the System or by variance or local upgrade approval in accordance with Title 5. IV. General Conditions 1. All provisions of 310 CMR 15.000 are applicable to the use of this System,the System owner and the Company, except those that specifically have been varied by the terms of this Approval. 2.
