The owner of the property on which a well for domestic water use is to be utilized shall:
Prior to construction of a well or undertaking any alteration to a well, apply to the Township for a well installation permit, providing, on the prescribed form: name and address of applicant, name and address of owner of the land where the well is to be drilled, name and address and license number of the well driller, site location and address of the property where the well is to be drilled and proposed date for drilling to begin. A site plan (sketch) drawn to scale showing the location and identification of existing or proposed buildings, structures, improvements, driveways, septic systems, and other wells within 100 feet of the proposed well must be attached to the application. The site plan need not be prepared by an engineer or surveyor so long as it is prepared to scale. At the time the application is presented to the Township for review, the applicant shall pay the application fee as established by resolution of the Township from time to time. In no case will the application be accepted for review prior to payment of the applicable fee.
Have all wells constructed by a qualified Pennsylvania licensed well driller to meet, at a minimum, the rules and regulations of this Part and any administrative agency of the Commonwealth of Pennsylvania.
Submit any relevant information or data concerning the constructed well to the Township, including a signed well completion report and a copy of well water test results obtained from the well driller to permit the Township to determine whether construction of the well complied with the requirements of this Part.
[Ord. 2012-7, 12/12/2012, § 6]
The source of supply shall be from a water bearing formation drawn not less than 35 feet from the ground surface. Wells shall be located at a point free from flooding, at a higher elevation and at the following minimum setback distances to existing or potential sources of pollution.
[Ord. 2012-7, 12/12/2012, § 7]
All wells supplying an individual water supply or semi-public water supply shall be equipped with watertight and durable casing of wrought iron, steel or plastic (PVC) with a minimum wall thickness of 0.1875 for iron and 0.175 for PVC (Schedule 80) or such other thickness as may be established from time to time by AWWA Standard A100.
The sections of casing shall be joined together by threaded couplings or joints, welding or other watertight approved method. The casing shall be carried to a minimum depth of 40 feet and meet competent bedrock then extended an additional 10 feet into firm bedrock or other impervious strata and grouted in place. Casing and grouting must be compatible. Pressure grouting is required for all wells by running tremie pipe to the bottom of and along the casing. Cement concrete or bentonite are required for use in grouting. Casing shall extend at least eight inches above ground surface. The borehole shall be at least three inches larger than the outside diameter of the casing to allow for grout.
In areas known to be contaminated, the minimum depth for casing shall be 40 feet the criteria established in AWWA Standards A100-84, as the same may be amended from time to time, must be followed.
Well Depth. The minimum drilled depth for any water well is 80 feet from surface of the ground.
Ferrous Casing. Ferrous casing shall be new pipe meeting ASTM or API Specifications for water well construction. It shall be equipped with a drive shoe or other effective casing seal and have full circumference welds or threaded pipe joints.
Non-Ferrous Casing. Non-ferrous casing shall meet appropriate ANSI, ASTM or NSF Standards for water well casing applications. It shall not be driven.
An annular space shall be provided between the well casing and the earth formation. It shall be completely filled with grout in one continuous operation under pressure from the bottom of the casing to the natural ground surface within 24 hours of completion of drilling. No activity in and around the well is permitted to occur within 48 hours after grouting of the casing, or within two hours if using bentonite.
All obstructions must be completely cleared prior to placement of grout material. The casing shall be sealed by grouting to a minimum of 15 feet each above and below the polluted or undesirable water-bearing zone.
During the installation of a pitless adaptor, grout material may be removed from the exterior of the casing in order to provide a watertight seal between the casing and this adaptor. For such an adaptor, a ditch at least three feet deep will be required along with conduits, stone, dust or sand. A sanitary well cap shall be incorporated for protection from leakage and identification of the well.
Packer. Packers when used shall be of material that will not adversely impact taste or odor or introduce toxic substances or bacterial contamination into the well water.
Gravel Packs. Gravel packs when used shall be 95% siliceous material and placed in uniform continuous operation. Refill pipes shall be Schedule 40 steel. The annular opening shall be surrounded by a minimum of 1 1/2 inches of grout. Protection from leakage shall be guaranteed by the contractor.
Pits. Pit installations are not permitted.
Pitless installations are those where the casing terminates above the ground surface. Where used, they shall be effectively sealed. All buried suction lines shall be encased. The access casing shall be protected against corrosion and shall extend at least eight inches above the natural ground surface and to a point below the frost line. This area shall be designed for blockage of water, insects and rodents.
Pitless adaptors cannot be installed with torch or flame, but must be installed using hole saw or drill.
Well Screens. Well screens shall provide maximum amount of open area while still maintaining structural strength. They shall have the size of openings based on a sieve analysis to preclude entry by sand, silt and other undesirable elements.
Well Cap. Install a secure, screened, varmint free well cap on all wells to prevent any surface pollutants from entering the well or any vandalism to the well or aquifer. In the event of a flowing well, the well cap must stop overflow from the well.
Well Tag. An identification tag must be permanently attached to each new or reconstructed water well or each geothermal well. These tags will be issued by the Township after the completion report and well analysis required by this Part are delivered to the Township and demonstrate compliance with the terms hereof.
Venting. Where venting is required, an overlapping cover or pipe with an opening facing downward shall be required. In no case shall openings be less than 12 inches from the ground.
Monitoring Wells. Monitoring wells shall be designed such as to minimize potential contamination of the aquifer and to maximize the information obtained from each such well.
Heat Pumps. Heat pump (geothermal) installations shall be designed and constructed to provide an effective watertight seal with the well casing or water storage reservoir and to prevent contamination from reaching the water chamber or interior pump surfaces. In closed loop systems, holes must be grouted from bottom to top with cement or bentonite. Open loop systems must conform to same requirements as water well.
Power Pump Installations. The base installed directly over a well casing or pipe sleeve shall be designed to provide an effective watertight seal. It shall be located in a flood-free area. Power pumps shall not be placed in pits. The pump and related equipment shall permit convenient access, removal, maintenance and repair. The suction opening shall be placed at least two feet below the maximum drawdown of the water in the well. However, it shall be located at a sufficient distance from the bottom of the well so as to prevent agitation of accumulated sediment.
Disinfection. Following completion of construction, the well shall be pumped continuously until the water discharge is clear. It shall be filled with water containing concentration of not less than 100 parts per million of free chlorine. A portion of this solution shall be recirculated directly to the well in order to insure proper agitation. The water shall not be used for a period of 24 hours to allow sufficient contact time to disinfect the system. Other combinations of water/chlorine concentration and time interval may be used if demonstrated equally effective to the satisfaction of the Township's dully appointed representative. Disposal of the purged water shall be at a point so as to minimize adverse effects to aquatic life and in no way directed into any subsurface sewage disposal system. One ounce of dry calcium hypochlorite dissolved in 52.5 gallons of water makes the proper strength disinfectant solution.
If pump and piping is not installed by the well driller, the owner and its contractor are responsible for proper installation of check valves and backflow protection. Backflow protectors must be incorporated into the system and be used as needed for each outside water hose connectors. At least two check valves must be incorporated into each water system that derives water from a well.
A cross-connection prevention assembly shall be provided. For semi-public water supplies, this device is required to be installed at any fixed potable water outlet to which a hose may be connected.
Well Analysis. After well disinfection, the owner or its representative shall collect and have water samples analyzed for pH, total solids, iron, nitrate-nitrogen, and coliform bacteria. The owner or its representative shall utilize the appropriate means and methods for sampling and stabilization, and obtain sample analysis from a certified lab. One copy of the analysis results shall be provided to the owner of the well and one copy provided to the Township. If the well analysis demonstrates that the water samples comply with this Part and the completion report addressed in Subsection 20 of this section has been submitted and accepted, the Township shall issue the well tag and the owner or contractor shall affix the well tag to the well.
Completion Report. The owner or its representative shall submit one copy of DCNR's water well completion report form 8700-FM-TG-5001S, as may be amended, to the Township for review and approval. In addition, distribute the remaining copies of this form as directed including one copy to the owner. In the case of geothermal wells, a report must be filed indicating the well was constructed in accordance with this Part.
[Ord. 2012-7, 12/12/2012, § 8]
A permit is required for any existing well that is to be abandoned. At the time the application is presented to the Township for review, the applicant shall pay the application fee as established by resolution of the Township from time to time. Drilled wells shall be filled and sealed by cement, concrete or bentonite grout. Hand dug wells shall be filled with clean stone to within 10 feet of the top of the well, then concrete shall be placed to within two feet of ground level. The top two feet may be covered with topsoil.
Dry wells being abandoned must be filled with clean stone and the top 18 feet filled with cement or bentonite; however, the top two feet may be covered with topsoil.
After the well has been filled as required by this section, the contractor shall submit all relevant information or data concerning the abandonment to the Township for review and approval by the Township.
