For Timed dosing use the timed dosing worksheet use the normal tank worksheet to determine the V factor for the tank first. Sand mound worksheet. Based on Converse and Washington State approach and diagrams. Pressure Distribution Network Design by Converse. This covers the technique as expanded on by the Pressure Distribution design worksheet, and is referred to in the worksheet by the initials "PD". This is a PDF file. Pressure Distribution Design from Washington State.
This is used in the course reprinted in the handouts and is referred to in the worksheet as "WS", it includes the tables required to use the worksheet. Soil profile record sheet, as provided in the SPM. Spreadsheet for selection of design inputs using the SPM. Note that the blue cells are for inputs, other cells are locked. We will be creating an updated version for the SPM. File is in Excel macro enabled format, you must enable the macros for it to work. This is a work in progress, and is provided for interest not for anyone to rely on as a design tool.
Use this at your own risk and do not substitute it for proper design input analysis. If you want to save the results, save it to your computer rather than using in the web browser.

If you are short of time, as a minimum visit the Washington State site, download the Pressure Distribution documents and mound design worksheets above and obtain the EPA manual. Acrobat Reader for reading and converting PDF files.
The old Version 1 SPM and amendment is no longer available there and is copied here for your convenience. There is also the older EPA manual, which is still of some interest, particularly as it is the one used by Washington State.
The publications page is here. Check out the Nitrogen reduction report PDF. There are various PDF documents available on a sub page. Alberta Private Sewage Systems Standard of Practice Handbook This site contains useful guidelines for system design, with some very simplified worksheets. Useful information on freezing conditions and other design considerations. National Small Flows Clearinghouse Has a large archive of publications.
Delaware ground water discharges section Another site with design guidelines, includes a section on sand lined trenches. Wake County's Well, Wastewater and Development division with info on their pressure manifolds.
Sewage Wiki page and sewage treatment --add your own information. Our extensive use of engineering tools such as SolidWorks 3D parametric solid modeling software, and MasterCAM commuter-aided manufacturing software allows our experts to design, test, and build high quality products in our modern 50, square foot facility. Our machining department includes computer numerical control CNC lathes, routers, and mills for repeatable, precision machining and production.
Not only do we manufacture equipment for the geothermal heating and cooling industry, our entire facility is heated and cooled with geothermal, and we utilize our own products to help harvest this clean, renewable thermal resource.
We are always releasing new and innovative products. Address changes are not noted on the individual approvals. Through broad field use in Massachusetts or other states, alternative systems with Certification for General Use will provide a level of environmental protection at least equivalent to that of a conventional on-site system designed in accordance with CMR These systems can be used anywhere a conventional Title 5 system can be installed.
The system owner is required to have inspection and testing performed as required by the approval on a regular schedule. All alternatives in other categories of approval could eventually be certified for General Use. Polyethylene Septic Tank by Norwesco, Inc. Piloting is intended to provide field-testing and a technical demonstration to determine if a particular alternative technology can or cannot function effectively.
Technology is only approved when the Department has determined, based on relevant technical data, that the proposed alternative is likely to be capable of a level of environmental protection at least equivalent to that of a system designed in accordance with CMR These systems are generally approved for nitrogen reduction but can be approved to evaluate reduction of other parameters.
Up to 15 systems can be installed and tested for a minimum of 18 months. The system owner is required to have inspection and testing performed as required by the approval on a regular schedule throughout the Piloting period. Phosphorus Reduction. This category is intended to evaluate, under actual field conditions, alternative systems that appear technically capable of providing levels of protection at least equivalent to those of a standard on-site disposal system.
The system owner is required to have inspection and testing performed as required by the approval on a regular schedule throughout the Provisional Use period. Up to 50 systems can be installed per technology. These systems can be installed for new construction or on remedial sites to replace a failed system.
Provisional Use Approval. Biofilter - for gpd to less than 10, gpd by Waterloo Biofilter Systems, Inc. Remedial Use-approved alternative technologies are used to improve existing conditions at a particular facility or facilities served by a failed, failing or nonconforming system.
The alternative system shall have evidence of effective past performance for at least one year of general usage in another state and will provide a level of environmental protection at least of a system designed in accordance with CMR The alternative can be used where there is no increase in design flow at the facility.
These systems can only be installed on remedial sites to replace a failed system. Effluent tee filters are approved for installation at the outlet of the septic tank in lieu of an outlet tee. When installed on a septic tank, an appropriate outlet cover must be installed and maintained at grade and the filter must be inspected and cleaned at least on an annual basis. More information about effluent filters is available from the Barnstable County Health Department see link below.
