Editor's Note: Under the present form of township government, there is no longer a Board of Health. The legislative functions of the Board of Health are now performed by the Township Council.
Unless otherwise stated in this chapter, the latest revised regulations of "Standards for the Construction of Individual Subsurface Sewage Disposal Systems" (N.J.A.C. 7:9-2.1 through 7:9-2.97) shall apply to all individual subsurface sewage disposal systems that are designed and constructed in the Township of Bridgewater, notwithstanding anything to the contrary contained in this chapter.
A. 
No person shall locate, construct or alter any individual sewage disposal system until a permit shall have been issued by the Board of Health.
B. 
The Board of Health may issue a permit if an application for the same is accompanied by a certificate made by an engineer, licensed to practice professional engineering in New Jersey, stating that the design of the individual sewage disposal system, as proposed, is in compliance with the code.
A. 
New individual disposal systems shall not be placed in operation, nor shall new dwellings or buildings or additions thereto be sold or occupied, which must rely on such a system for sewage disposal, until the Board of Health shall have issued a certificate indicating the disposal system has been located and constructed in compliance with the terms of the permit issued and the requirements of the aforesaid code. Issuance of such certificate shall not be required for alterations to an existing individual sewage disposal system.
B. 
The Board of Health may issue such a certificate if an engineer licensed to practice professional engineering in New Jersey submits a statement in writing, signed by him, to the Board of Health that the disposal system has been located and constructed in accordance with the terms of the permit issued and the requirements of the aforesaid code.
C. 
An as-built sketch plan showing the exact location of the individual sewage disposal system shall be submitted to the Board of Health by the design engineer before a certificate of compliance can be issued.
A. 
Permit to conduct a percolation test.
(1) 
A permit shall be obtained from the Board of Health before a soil characteristics test, as prescribed in this section, can be conducted. A nonreturnable fee of $20 per test per individual lot or proposed lot must accompany the application.
(2) 
The permit shall be valid for one test series on each building lot.
B. 
Test validity. Soil characteristics test results shall remain valid for five years and will be invalid thereafter.
C. 
Procedures for conducting soil percolation tests.
(1) 
A series of four percolation tests shall be performed at the site of each disposal area. The four test holes shall be uniformly distributed throughout the disposal area. Preliminary tests for subdivisions shall be made in the same manner. Test hole locations for all soil characteristics tests are subject to the approval of the administrative authority or its duly appointed representative.
(2) 
Reports shall be furnished to the administrative authority for final approval indicating the percolation test results as the average percolation rate for the four test holes in minutes per inch, the date of the test, the effect of recent rain or lack of rain, the apparent moisture of the soil prior to the test, the depth to groundwater when encountered, the number of preliminary tests made to determine apparent saturation, the type or types of soil encountered, together with the thickness of each layer, and all other factors affecting percolation test results.
D. 
Filing of percolation report. The engineer who performs the soil characteristics tests shall provide the Board of Health with a copy of the test results within 10 days after the tests are conducted. Test results which are submitted after the aforesaid 10 days shall not be acceptable.
E. 
Rejection of percolation tests and/or soil log information. A proposed site for an individual subsurface disposal system shall be rejected for any one of the following reasons:
(1) 
A percolation rate greater than 60 minutes per inch.
(2) 
An impervious formation (soil, shale or rock with a percolation rate exceeding 120 minutes per inch) was encountered within eight feet of the existing grade.
(3) 
Groundwater and/or indications of high seasonal groundwater elevations were found less than six feet from the existing grade.
F. 
Alternate designs other than conventional septic systems.
(1) 
If a percolation test and/or soil log was rejected pursuant to § 173-4, a licensed engineer may submit to the Board of Health an alternate design for an individual subsurface system. The Board will review the plan and approve or disapprove the plan within 90 days after it is submitted. All decisions will be rendered during a public meeting of the Board of Health.
(2) 
Upon approval of an alternate design by the Board, the following statement shall be recorded by the applicant on the property deed: "Due to the unique soil drainage characteristics of this property, the residence located thereon is served by a sewage disposal system that has been classified as an alternate design by the Township of Bridgewater Board of Health. An alternate design sewage system shall be defined as any system (other than the conventional septic system) which has been recognized by competent engineering authorities as an effective alternate to the conventional septic system but which has not as yet been proven effective for at least five years of continuous use in the Township of Bridgewater."
(3) 
No permit for the construction of the alternative sewage system shall be issued until proof has been provided that the above statement has been filed as required with the office of the Somerset County Clerk.
(4) 
The owner of any property on which a specially designed septic system has been constructed shall give notice, in writing, of the existence of such system to any prospective buyer of the property prior to the execution of the contract of sale. Such notice shall be included in the listing agreements and shall be included in the contract of sale and the deed.
A. 
Select fill to be used under disposal field. Whenever shale soil structures are encountered and/or a percolation rate of 10 minutes per inch or faster is identified, a minimum of four feet of filtering media or select fill must be placed under the entire disposal field.
B. 
Specifications of select fill:
(1) 
Sandy soil (material with a silt and clay content not less than 10% by weight nor more than 20% by weight, of the portion of the soil finer than two millimeters). This portion of the fill should not be less than 85% by weight of the total recommended fill material.
(2) 
Coarse fragments (1/4 inch or larger in diameter). This portion of the fill should not exceed 15% by weight of the total recommended fill material.
(3) 
Silt and clay are soil particles that are smaller than 0.05 millimeters. Sand is smaller than 2.0 millimeters but larger than 0.05 millimeters.
(4) 
Four feet of select fill under the disposal field will also be required where the groundwater is elevated.
C. 
Impervious formation less than 10 feet: fill required.
(1) 
Fill dirt will be required to be placed over the entire disposal field if there is less than 10 feet of soil from the final grade to an impervious formation.
(2) 
The fill dirt shall have a percolation rate similar to that of soil found in the ground over which the fill is placed.
D. 
Minimum design rate for all septic systems. All proposed new individual subsurface sewage disposal systems shall be designed at a minimum percolation rate of 21 to 25 minutes per inch.
E. 
Permanent markers for septic tank and distribution box. The location of the access opening for the septic tank and distribution box must be permanently identified at finished grade.
F. 
Scarifying side wall and bottom areas of disposal field. Before placement of filter material, all side wall and bottom areas of the disposal field shall be scarified.
The Board of Health may order all further work in and about any individual sewage disposal system, which is being erected or installed in violation of the code, to be stopped forthwith, except such work as shall be necessary to remedy such violation and, thereafter, the work continued without any violation of any of the provisions of the code and after issuance of any such order and the service of a copy thereof upon any person connected with or working in and about the erection or installation of any such disposal system or any part thereof, no further work shall be done except as aforesaid.
