1. POWTS soil saturation submittal time extended
by Leroy G. Jansky, POWTS Wastewater Specialist, Chippewa Falls
There will be an extension of the time period for submitting soil saturation determinations under Comm 85.60(3)(I)1 (observation pipe method). The determinations are supposed to be submitted within 60-days of the completion of observations.
Requests for review of information from sites where the last observations were made on May 31, 2001 should have been submitted for review by July 30. The period is now extended to December 31, 2001.
The submittal requirements for soil saturation determinations are new this year. Back in March, the Safety and Buildings Division implemented a grace period for submittal of the intent to monitor notice that is required by Comm 85.60(3)(b)1 because many certified soil testers were unaware of the new requirement.
The division has found a situation similar to the monitoring information has occurred regarding the determinations. S&B decided to extend the 60-day submittal deadline to December 31, 2001. The extra time for submittal should be sufficient for any projects that have been put on the back burner to be completed and submitted. The decision to allow a time extension negates the need for a petition for variance in order to submit soil saturation results beyond the codified 60-day limit for submittal.
The standard review fee of $100 per site will be required with each soil saturation determination submittal. In addition, persons submitting determination results under Comm 85.60(3) should be aware that a new Soil Saturation Determination Report form (R.06/01) was released in early June. This form may be used when submitting observation data and can be found on our web site at http://www.commerce.state.wi.us/SB/SB-DivForms.html, in the POWTS section. The forms are also available from local sanitary permit issuing agents or S&B's Wastewater Specialists.
Questions about reporting soil saturation determinations may be directed to the Wastewater Specialists or specifically to Leroy Jansky at 715-726-2544 or Ljansky@commerce.state.wi.us.
2. New sources of plumbing info - In WPCR and on the Internet
by Lynita Docken, S&B Plumbing ProgramManager, 608-785-9349, ldocken@commerce.state.wi.us
The S&B Plumbing Plan Reviewers and Plumbing Consultants get together with a few other S&B staff for a monthly teleconference to talk over nuts and bolts technical issues. Conclusions from the discussions have been put into a plumbing database in order to back-up memories and help improve consistency.
The information in that database recently has been put on the S&B WebSite, linked from the Plumbing Program page, http://www.commerce.state.wi.us/SB/SB-PlumbingProgram.html. The information there will be added to and maintained on a regular basis.
I'm planning to share in the WPCR some of the points from those monthly meetings, when I can, so readers can be aware of the issues addressed. Below are some of the points from the August 2001 staff discussion. By the way, S&B has a new email address for people who wish to ask technical plumbing questions and make comments, plbgtech@commerce.state.wi.us.
Sewer Offsets and Manholes
A question came up concerning the requirement for cleanouts or manholes in sewer offsets. Comm 82.35(3)(b)2.a requires that all sanitary building sewers eight inches or larger in diameter be provided with a manhole at every change in direction of 45 degrees or more. See Figure 1 (Not available until Sept. 10).
Now, what if the 45-degree change is made in small increments? Like two 1/16 bends instead of one 1/8, 1/6, or 1/4 bend? See Figure 2 (Not available until Sept. 10). The piece of pipe shown in Figure 2 could be two feet long or two hundred feet long.
It seems logical to assume that the code developers at the time this section was created must have had a reason for choosing a 45-degree change in direction. If there is a piece of pipe separating two fittings of less than 45 degrees, it's not a 45-degree change in direction. It's two changes in direction of a lesser amount.
Most of you reading this article have (at some time, out of necessity) created a 45-degree elbow from a street 1/16 bend and a regular 1/16 bend. In reality, this is creating a 45-degree bend. So, if two fittings, a street and regular, or two street bends are installed to form one fitting of 45 degrees or more, a manhole would be required. See Figure 3 (Not available until Sept. 10).
3. POWTS component design manuals have a few corrections
One of the innovations included in the July 2000 remaking of Comm 83, the Private Onsite Wastewater Treatments Systems code, is the use of component design manuals.
Specifications for nine particular POWTS systems have been approved by the Safety and Buildings Division in the form of component manuals that provide package designs that have been reviewed and identified as code compliant.
A set of the nine manuals was released in June of 1999 and three more manuals were released in January of 2001. The January 2001 set of component manuals are updates of three 1999 manuals - Mound, In-Ground Soil Absorption, and Pressure Distribution. Both the 1999 and 2001 versions may be used to design POWTS; the 2001 version resulted from additional thinking and discussion of the systems.
There are now a few corrections to the two different Pressure Distribution Component Manuals. The corrected pages have been provided to the state Document Sales Unit, which sells the manuals. However, some manual users may have purchased copies before the corrections were made.
There is one corrected page of the 1999 Pressure Distribution Manual - Table 6, Friction Loss in Plastic Pipe (22 of 30).
There are three corrected pages of the 2001 version. Those pages contain Table 1 Flows and Loads (3 of 30), Graph 3 Minimum Lateral Diameter... (14 of 30), and Graph 4 Minimum Lateral Diameter... (15 of 30).
The corrected pages may be viewed and downloaded/printed from the Safety and Buildings Division WebSite, http://www.commerce.state.wi.us/SB/SB-DivPublications.html, in the component manuals section.

8. Orenco's AdvanTex System tanks approved, could be used in POWTS
by Mike Beckwith, S&B Plumbing Product Reviewer, mbeckwith@commerce.state.wi.us, 608-266-6742
Orenco Systems Inc. has received plumbing product approval for their AdvanTex™ Treatment system models AX10 and AX20.
The systems, consist of a fiberglass basin with lightweight textile fabric sheets hung inside. Effluent from a processing tank is sprayed on top of the fabric sheets, then the effluent is distributed to a dispersal/treatment component. Some of the effluent is also discharged into the processing tank. This system works similar to a recirculating sand filter. The fiberglass tank is designed to sit on top of the processing tank(s).
The system may be set up to function in one of four treatment flow scenarios. The scenarios are:
A) Mode 1, Blend Discharge - This system type recirculates the wastewater into the downstream compartment of a two-compartment processing tank or the downstream tank of a two-tank processing tank system, with the effluent exiting from the downstream compartment or tank to a dispersal/treatment component.
B) Mode 1, Filtrate Discharge - This system type recirculates the wastewater into the downstream compartment of a two-compartment processing tank or the downstream tank of a two-tank processing tank system, discharging the effluent exiting directly from the textile filter module to the dispersal/treatment component.
(There is no Mode 2.)
C) Mode 3, Blend Discharge - This system type recirculates the wastewater into the downstream compartment of a two-compartment processing tank or the downstream tank of a two-tank processing tank system, discharging the effluent from the downstream compartment or tank of the processing tank(s) system to the dispersal/treatment component.
D) Mode 3, Filtrate Discharge - This system type recirculates the wastewater into the downstream compartment of a two-compartment processing tank or the downstream tank of a two-tank processing tank system, discharging the effluent exiting directly from the textile filter module to the dispersal/treatment component.
Mode 3 facilitates nitrogen reduction by recirculating the effluent into the first compartment of a two-compartment processing tank or the first tank of a two-tank processing tank system. The filtrate discharge portion of the process will help reduce the fecal coliform below the 1000 cfu/100 ml level. Regardless of the treatment flow scenario, the BOD5, and TSS will be at or below 30 mg/L. Therefore, when the system is set up for filtrate discharge, the dispersal/treatment cell must be include a pressurized distribution network in accordance with Comm 83.44 (5)(b).
Since the S&B approval is only for the tank that houses the textile fabric, an effluent distribution piping, product approval must be obtained for any prefabricated processing tank serving this product.
Also, plan approval for the installation must be obtained from the Safety and Buildings Division or a designated agent. The processing tank system must consist of either a two-compartment tank or two single compartment tanks. The upstream compartment of a two compartment tank or the upstream tank of two single-compartment tanks must have a treatment capacity equal to at least two-thirds of the Design Wastewater Flow.
The downstream compartment of a two compartment tank of the downstream tank or two single-compartment tanks must have a treatment capacity equal to at least one-third of the DWF.
Depending on the number of bedrooms the system serves, there are various combinations of the AX10 and AX20 units. When more than one AX unit is required, the units must have the effluent distributed to them in a parallel flow pattern.
Systems that use this product and are to serve more than six bedrooms from a one- or two-family residence, must be submitted to S&B as individual system designs. The submittal must include design approval from Orenco Systems.
9. Brochure asks public to pay attention to possible need for other permits
by Henry Kosarzycki, S&B Agent Monitor, 262-548-8615, hkosarzycki@commerce.state.wi.us
Paying attention to the variety of possible permits needed for different building projects is the theme of a brochure the Safety and Buildings Division has prepared. The brochure will be provided to municipalities to distribute free to people contacting local government departments.
The brochure is available for download from the S&B WebSite, http://www.commerce.state.wi.us/SB/SB-DivPublications.html, and will be printed this fall for distribution to all municipalities which ask for copies. Registration to receive copies is also on the WebSite.
Leading customers to ask the right questions is important to getting all the needed permitting steps taken. Time, money, and aggravation are at stake.
S&B repeatedly hears negative reports from people who took one step in one permitting process, but were "burned" because they didn't know about or follow through on other steps needed. They got a zoning permit, but no building permit. They didn't submit for plumbing plan review for a commercial project because they thought it was "just remodeling."
Whatever the reasons for not getting the proper permits, people become disturbed with government officials when a problem is discovered in trying to complete a local or state permitting process. The new brochure is meant to help stop some of that frustration before it occurs.
The brochure makes a number of suggestions for people who are starting building projects: Contact your local village, town or city government. Ask what permits you need locally. Ask if there are local inspectors to help figure things out. Ask what other agencies' permits you may need. Ask what needs to be done first, then second, then third. Contact the county planning or zoning department. Ask if they have authority over the property you have in mind. Ask if they know of any other permits or processes you need to pay attention to.
The brochure says: Even if a property has the proper zoning, projects probably also require another permit if something is erected, constructed, improved, enlarged, altered, converted, repaired, filled in, moved or demolished. The same governing body does not necessarily issue all the permits associated with a project. There are many variations as to what permits are needed; it's in the customer's best interest to ask about the variations.
Federal, state, regional planning, county, municipal, special district, sanitary, erosion control, flood plain, zoning, driveway and well issues are examples of the various combinations that can affect projects. Municipal officials obviously concentrate on regulated objects constructed installed and altered in their own community. Building construction or alteration, mechanical systems, fences, or signs are a few of these regulated objects. County and regional agents regulate and are involved with the impact those regulated objects will have on a wider environment. Erosion control, storm water management, zoning, and sanitary permits are examples of these permits. Federal and state regulatory agencies are typically associated with review and inspection duties associated with federal law or state statutory regulations. The Americans with Disabilities Act, Environmental Protection Agency regulations, and state building codes are examples of these rules and regulations.

13. Questions reviewed - Back-vented circuit and horizontal wet vent
by Don Hough, S&B Plumbing Consultant, Hayward, 715-634-4804. dhough@commerce.state.wi.us
Comm 82.31(9)(a)2 says that each fixture trap that is an integral part of the fixture shall be protected with a vent located so that the developed length of the fixture drain piping from fixture outlet to the vent connection is within limits set forth in Table 82.31-1.
For a floor outlet water closet or similar fixture, the point where the fixture drain piping turns horizontal shall be considered the fixture outlet.
Comm 82.31(9)(b) says a vent shall not connect to a fixture drain within the distance equal to two diameters of the drain piping from the weir of a trap.
Are the drawings below in compliance with the referenced code language?
Look at the first drawing showing the water closet being wet vented by the lavatory. The drawing either shows a 90-degree bend with a heel outlet horizontal wet vent or this is a sanitary tee on its back with the inlet run connection reduced, receiving the discharge from a lavatory drain that wet vents the water closet.
The plumbing code strictly prohibits the use of a heel inlet bend when the heel inlet is in the horizontal position (Comm 82.30(9)(c)1).
The code does allow a sanitary tee on its back since the tee meets the same radius requirements as the first 90-degree bend downstream from a water closet (Comm 82.30(8)(a)2.3).
It may be good to address just why the heel inlet elbow is not used and prohibited from this use.
The heel inlet elbow fitting, installed to serve as the connection to wet vent a water closet, has been used in the past on plumbing installations that utilized the standard of that day in materials: cast iron hub, spigot pipe and fittings, and threaded iron pipe reducing inlets. If you spend time working out of a service truck, occasionally on one of your calls you will come across an old heel inlet fitting wet venting a water closet. A 4-inch cast iron service weight (or extra heavy) elbow with a 2- inch threaded heel inlet has two problems that mean service trouble. One is that there is no pitch on the galvanized horizontal portion of the wet vent, which makes its use non-code compliant.
Secondly, over a period of time the flushing of the water closet leaves a hard crusty deposit at the base of the 4-inch elbow, just in front of the 2-inch inlet.
The heel inlet bend is "ill fitted" for this application, mainly because of maintenance. The horizontal portion of the wet vent would plug, causing drain stoppages in the lavatory drain and vent problems for the water closet.
It should be noted that the maintenance problem on this type of installation might not be so much of a concern with the use of PVC, ABS, and hubless cast iron waste and vent piping.
Someone will inevitably ask what the difference is between a heel inlet elbow on its back and a sanitary tee with a reducer on the inlet run on its back.
The answer is very little, from a fitting standpoint, but a lot from a code and maintenance standpoint. The sanitary tee is allowed. The other is not.
Now let's take a look at several other code references that pertain to our sketches. Comm 82.31(9)(a)1 states that each fixture trap which is not an integral part of the fixture shall be protected with a vent located so that the developed length of the fixture drain piping from the trap weir to the vent connection is within the limits set forth in Table 82.31-1.
This code reference refers only to fixture traps which are not an integral part of the fixture.
The standard water closet used today has a integral fixture trap with the trap weir located at the point where the water in the closet bowl is at design level. Any further introduction of water into the bowl will drain by gravity through the fixture outlet.
Therefore, the trap weir of a water closet is not used as a determining point to establish the developed length fixture to vent. Comm 82.31(9)(a)2 is the code reference that establishes the point from where to measure the developed length of the fixture drain piping from the fixture outlet to the vent connection.
For practical purposes, a fixture trap that is an integral part of the fixture, such as a water closet, has a designated point where the fixture drain pipe turns horizontal. That point is considered the fixture outlet. There is no mention of trap weir in this code section, and we consider the point where the fixture drain piping turns horizontal as the fixture outlet, so as to create a point to measure developed length from the fixture drain to vent connection.
Because the water closet trap and trap weir are integral, we can conclude that Comm 82.31(9)(b), referring to the minimum distance of a vent connection, does not apply. The code states: "A vent shall not connect to a fixture drain within the distance equal to two diameters of the drain piping from the weir of a trap." This particular code reference applies to standard non-integral fixture traps, preventing the installation of "crown vents." Vents with close proximity to the upper bend of the P-trap can interfere with the flow of water discharging through drain piping, becoming fouled and plugged through normal use.
The second drawing appears to be circuit wet vented water closets.
The circuit vent has been used extensively over the years as an effective vent that uses "back" venting design. Again, the 4-inch sanitary tee on its back would comply with the intent of the code (Comm 82.30(8)(a)1 and 2), meeting the minimum radius for the first 90-degree change of direction downstream from a water closet. Also, the tee is not listed as a prohibited fitting in Comm 82.30(9)(c).
The heel inlet elbow installed in the horizontal position is not permitted.
A horizontal wet vent cannot serve four water closets. Comm 82.31(13)(b) is where we find the horizontal wet vent limitations that prevent such a vent from serving more than two water closets.
This second drawing shows a typical public water closet layout. The only other requirement for such an installation would be a relief vent located downstream of the most downstream water closet and upstream of any other drain connections, according to Comm 82.31(10)(b).
There are advantages to both venting installations. Horizontal wet vent requirements allow the reduction of the diameter of the drain piping between the circuit vent connection and relief vent connection, while the installation of a circuit vent requires the drain to be full-sized to the circuit vent connection. (Drain and Vent System Design, revised 2/99, p. 46).
