Page 2 Manual with any other product is prohibited. The processes and design criteria contained herein are based solely on our experience with and testing of Advanced Enviro-Septic and Enviro-Septic. Substitution of any other large diameter gravelless pipe will result in compromised treatment of wastewater and other adverse effects.

Page 4: Background
“next generation” of our Enviro-Septic technology. The AES product incorporates Bio-Accelerator, a proprietary enhancement that screens additional solids from effluent, accelerates treatment processes, assures even distribution and provides additional surface area. Each foot of Advanced Enviro-Septic pipe provides over 40 sq. ft. of total surface area for bacterial activity.

Table E (Multi-Level™ bed) for the daily design flow. Note: if the daily design flow is over 900 GPD, a combination system must be used. Contact PEI for high strength wastewater recommendations. Step #2: Using the system slope and perc rate find the minimum row spacing from Table B (single level) or Table F (Multi-Level™).

(800) 473-5298. Exceptions to any Maine rules other than those specifically discussed in this Manual require a state waiver. 12.0 Advanced Enviro-Septic and Enviro-Septic Sizing AES and ES use the same bed sizing tables, pipe and installation requirements noted in this manual. See para. 14.1, below for additional Advanced Enviro-Septic requirements.
Page 11: Certification Requirements
When daily design flow is determined by water meter use for commercial systems, refer to the Maine Rules. d) PEI recommends taking the average daily use from a peak month and multiply it by a peaking factor of 2 to 3 times.
Page 12 14.8 Flow Equalizers Required All distribution boxes used to divide effluent flow require flow equalizers in their outlets. Flow equalizers are limited to a maximum of 20 GPM per equalizer. 14.9 Garbage Disposals (a.k.a. Garbage Grinders) No additional AES or ES pipe is required when using a garbage disposal (grinder). If a garbage disposal is utilized, follow the State’s requirements regarding septic tank sizing.
Page 13: Basic Serial Distribution (Single Level)
14.16 Two Inch Rule D-BOX HIGHER THAN MAX. LIQUID LEVEL IN PIPE The outlet of a septic tank or distribution box must 2" - 4" be set at least 2 in. above the highest inlet of the LEVEL AES or ES row, with the connecting pipe slope not less than 1% (approximately 1/8 in.
Page 14: Basic Serial Distribution (Multi-Level™)
16.0 Basic Serial Distribution (Multi-Level™) Basic Serial Multi-Level™ systems can use AES or ES pipe and must conform to the requirements for single level basic serial systems except: a) Pipe requirements per Table E (see para. 7.0, pg. 5). b) Row spacing per Table F (see para. 8.0, pg. 5). c) All Multi-Level™...
Page 15: Butterfly Configuration
18.0 Butterfly Configuration a) A “butterfly configuration,” is considered a single bed system with two or more sections (can also be D-box or Combination configurations). b) Maximum length of any row is 100 ft. c) Serial Section loading limit is 500 GPD. d) Beds can contain any number of serial sections.
Page 16: Combination Serial Distribution (Multi-Level™)
19.2 Section Length Requirement a) Each section must have the same minimum linear feet of pipe. b) The minimum linear feet of pipe per section is determined by dividing the total linear feet required in the field by the number of sections required. c) A section may exceed the minimum linear feet required.
Page 17: D-Box Distribution (Single Level)
21.0 D-box Distribution (Single Level) a) All rows in this configuration must be the same length. b) Flow equalizers must be used in the D-box. c) Use a Manifold to connect the ends of all rows. Manifold to be sloped toward AES or ES pipes. d) Maximum row length is 100 ft.
Page 18: In-Ground Bed Systems
Illustration of an elevated level bed: 23.1 System Sand Extension In Systems sloping more than 10%, a System Sand extension is required. The System Sand extension area is additional System Sand added to the down slope side of all systems sloping more than 10%. The System Sand extension area is a minimum of 6 in.
Page 19: Trench Systems
26.0 Trench Systems AES and ES pipe may be installed in trench configurations on level or sloping terrain and may utilize serial, combination or D-box distribution. A minimum of 3 in. of System Sand are required above and 6 in. below, between and around the perimeter of all pipes.
Page 20: System Sand And Sand Fill Requirements For All Beds
30.5 Velocity Reduction The rate at which effluent enters the AES and ES pipe must be controlled. Excessive effluent velocity can disrupt solids that settle in the pipes. a) Effluent must never be pumped directly into AES or ES pipe. b) A distribution box or tank must be installed between the pumping chamber and the AES or ES pipe to reduce effluent velocity.
Page 21: Venting Requirements
larger than 6 in. are allowed in the Sand Fill. System Sand may be used in place of sand fill; however, this may increase material costs. 32.0 Venting Requirements An adequate air supply is essential to the proper functioning of Presby Systems. Venting is required for: a) All systems using AES pipe.

33.8 Replacement System In the event of system malfunction, contact PEI for technical assistance prior to attempting Rejuvenation procedures. In the unlikely event that a system needs to be replaced … a) It can be reinstalled in the same location, eliminating the need for a replacement field reserve area.
Page 25 Use a laser level or transit to install rows level. Variations beyond 1 in. (±1/2") may affect system performance and are not acceptable. 34.11 Correct Alignment of Advanced Enviro-Septic Bio-Accelerator Fabric The Bio-Accelerator (white geo-textile fabric) is to be positioned centered along the bottom of the pipe rows (sewn seam up).

10 ft. in length, with an outside diameter of 12 in. and a storage capacity of approximately 58 gallons. Each foot of Advanced Enviro-Septic provides over 40 sq. ft. of total surface area for bacterial activity.
Page 28 38.7 Bottom Drain A bottom drain is a line connected to the hole in the 6 o’clock position of a double offset adapter at the end of each serial section or each row in a D-box Distribution Configuration which drains to a sump and is utilized to lower the water level in a saturated system or to facilitate system rejuvenation (see illustration in para.

Detailed information about venting requirements can be found in Venting Requirements, para. 32.0, pg. 19. 38.24 High Strength Effluent High strength wastewater is septic tank effluent quality with combined 30-day average carbonaceous biochemical oxygen demand (CBOD) and total suspended solids (TSS) in excess of two-hundred and forty (240) mg/L.

Sections are limited to 500 GPD daily design flow maximum. 38.38 Serial Distribution Two or more pipe rows connected by a Raised Connection. Basic Serial distribution is described in detail in para. 16.0, pg.
