Township of Warminster, PA Well Rules and Regulations

All wells serving as a water supply shall be equipped with a watertight and durable wrought steel casing equivalent to Schedule 40 280 wall thickness. The section of casing shall be joined together by threaded couplings or joints, by welding. The casing shall be carried to a minimum depth of 40 feet and (then) extended an additional five feet into firm bedrock or other impervious strata and grouted in place.

The criteria established in AWWA Standard AI00-84 must be followed. Casings shall terminate a minimum of 18 inches above the surrounding, finished ground surface grade. All casings for water supply or geothermal return wells shall be fitted with an insect-resistant well cap.

Grout materials.

All grout information (type of cement or bentonite and number of bags of cement or bentonite used for grouting) must be submitted, in writing, on the form(s) provided by the Authority to the Authority by the well driller within 30 days of completion of the well drilling process.

In all well installations an annular space shall be provided between the well casing and the earth formation. The annular space shall be completely filled with approved grout materials, in one continuous operation, under pressure from the bottom to the natural land surface, within 24 hours after completion of the drilling. In the event that grouting is done following the completion of all drilling operations, care must be taken to prevent the entrance of drillers mud into the annulus during the completion of the borehole by the use of a rubber packer or other acceptable method. The annular space shall be completely cleared of all obstructions prior to the placement of the grout material. Exterior grouting methods must be used in this instance. The casing shall be sealed effectively against entrance of water from water-bearing zones which are subject to pollution, through which the casing may pass, by grouting a minimum of 10 feet above and 10 feet below the polluted or undesirable water-bearing zone. During the installation of the pitless adapter, grout material may be removed from the exterior of the casing in order to provide a watertight seal between the casing and the pitless adapter.

A curing time of 12 hours for Type III portland cement must be provided immediately following the placement of the grout. Drilling is not permitted during the curing period. If casings of smaller diameter are used in the lower portions of the well, effective watertight seals shall be provided between the casings where they telescope for a minimum distance of four feet.

The annular space of all well installations must be filled with one of the following listed grout materials:

(a)

Neat cement grout shall consist of a mixture of API Class G (or Class B similar to ASTM C150 Type II) and water in the ratio of 0.67 cubic feet (0.019 m³) of water per ninety-four-pound (42.7 kg) sack weighing approximately 228 pounds per cubic feet. A maximum of 6% by weight bentonite and 2% by weight of calcium chloride may be added.

(b)

Bentonite grout shall be a pure bentonite with at least 20% solids by weight when mixed with water. Hydration of the bentonite must be delayed until bentonite mix has been placed down the well. This can be done by using additives with the dry bentonite or in water; mixing calcium bentonite with sodium bentonite or by using granular bentonite which has less surface area.

(c)

In all well installations if rapid loss of grout material occurs during placement, coarse fill material (e.g., sand, gravel, crushed stone, dry cement) may be used in the zone or zones in which the rapid loss is occurring. The remainder of the annular space shall be grouted as provided below. In no case shall pouring, dumping or shoveling of grout material into the annular space be deemed an approved method of grout placement.

Grout placement.

Grout pipe outside casing. The minimum annular space of 1 1/2 inches around the entire outside of the casing shall be provided by drilling a borehole three inches larger than the outside diameter of the casing to be inserted. All grout shall be placed by pumping through the grout pipe. The entire interval to be grouted shall be open and without obstructions. The grout pipe may remain extended to the bottom of the interval during and after grouting or it may be raised slowly as a grout is placed, provided that the discharge end of the grout pipe remains submerged in the emplaced grout at all times until grouting is completed. In the event of interruption in the grouting operations, the bottom of the grout pipe shall be raised above the grout level and should not be resubmerged until the air and water have been displaced from the grout pipe.

Grout pipe inside casing. The bottom of the casing if fitted with a packer arrangement, also referred to as a cementing shoe or float shoe, and the casing is placed in the borehole a short distance off the bottom. The float shoe allows grout to be pumped through the grout pipe and upward into the annular space, while preventing grout leakage into the casing during grouting and after removal of grout pipe. Grouting is continued until cement appears at the surface at which time the grout pipe is disconnected from the float shoe. The float shoe is drilled out after the grout sets and hardens sufficiently.

Interior method two plug. The first plug separates the grout from the fluid in the casing, and the other separates the grout from the water pumped in above it. First, the casing is placed a short distance off the bottom. After pumping water through the casing to circulate fluid in the annular space and clear any obstructions from the hole, the first plug is inserted, and the casing is capped. A measured volume of grout is pumped in, which is sufficient to fill the annular space. The casing then is opened, and the second plug inserted. A measured volume of water is pumped in above the second plug until it is pushed to the bottom of the casing and most of the grout is expelled up and into the annual space. The water in the casing is held under pressure to prevent the backflow of grout until it has set and hardened.

Interior method upper plug. The casing is placed a short distance off the bottom, and the water is pumped into the casing to circulate fluid through the annular space to clear any obstructions from the hole. A measured quantity of grout slightly greater than that needed to fill the annular space is pumping into the capped casing. Because this grout is in direct contact with the drilling fluid, there will be a narrow zone of weak grout between the drilling fluid and good grout; however, this zone should remain inside the casing and not be forced into the annular space. The casing is opened, and a drillable plug is inserted. A measured volume of water is pumped in above the plug until it is pushed to the bottom of the casing and most of the grout is expelled up and into the annular space. The water in the casing is held under pressure until the grout sets and hardens.

Interior method capped casing. The casing is placed a short distance off the bottom, and water is pumped into the casing to circulate fluid in the annular space and clear any obstructions from the hole. The grout pipe passes through an airtight cap at the top of the casing and is positioned three to four feet above the bottom of the casing. The grout pipe is assembled so that it can be pulled through the cap a distance of about 20 feet after the injection of grout is completed. A bleeder valve is provided to release air from inside the casing as it is filled with water. The first step is to fill the casing and annular space with water. With the upper end of the casing closed, grouting is started by forcing the cement through the grout pipe upward into the annular space. Grouting is continued until the cement overflows around the casing at ground surface. Just enough water is pumped to clear the cement from the grout pipe, and the grout pipe is lifted free of the grout. Both the casing and grout pipe shall be kept tightly closed under pressure until the cement sets and hardens.

(6)

Grout displacement method. The hole is filled with the estimated volume of grout required to fill the annular space, and the casing is lowered into the hole. The bottom of the casing is closed in a tight, drillable plug. Guides often are used to keep the casing centered in the hole. As the casing is lowered, the grout is forced upward around it to fill the annular space. If the pipe does not sink to the bottom under its own weight, it is filled with water.

(7)

Unconsolidated formations. When drilling through an unconsolidated formation a steel drive shoe shall be required. Grouting shall be done in accordance with the following:

(a)

If caving conditions are experienced on wells deeper than 30 feet, the annular space shall be grouted from the point where caving occurred or from a depth of 30 feet, whichever is greater, to land surface.

(b)

If the annular space cannot be grouted in accordance with these regulations, the well shall be abandoned and sealed in accordance with § 26-307 of this Part 3.

(8)

Other grouting methods and materials may be used subject to prior written approval of the Department.

Packers. Packers, when used, shall be of materials that will not impart taste, odor, toxic substances or bacterial contamination to the well water.

Well screens. Well screens, when used, shall:

Provide the maximum amount of open area while still maintaining structural strength.

Have the size of openings in the screen based on a sieve analysis of the material contained in the surrounding geological formation or gravel pack.

Be constructed of materials resistant to damage by chemical action of groundwater or cleaning operations.

Have sufficient diameter to provide adequate specific capacity and low aperture velocity. Usually, the entrance velocity should not exceed 0.1 feet per second.

Be installed so that the pumping water level remains above the screen under all operating conditions.

(6)

Be designed and installed to permit removal or replacement without adversely affecting watertight construction of the well.

(7)

Be provided with a bottom place or wash down bottom fitting of the same material as a screen.

Gravel packs. Gravel packs when used:

Shall be well rounded particles, 95% siliceous material, that are smooth and uniform, free of foreign material, properly sized, washed and disinfected immediately prior to or during replacement.

Shall be placed in one uniform continuous operation.

Gravel refill pipes, when used, shall be Schedule 40 steel pipe incorporated within the pump foundation and terminated with screwed or welded caps at least 12 inches above the pump house floor or concrete apron.

Gravel refill pipes located in the grouted annular opening shall be surrounded by a minim urn of 1.5 inches of grout.

Protection from leakage of grout into the gravel pack or screen shall be provided.

Pit installations. Pit installations are used where the casing terminates below the ground surface. Where well pits are used, such pits shall be maintained free of water at all times. The floor of the pit shall be a watertight, reinforced concrete platform at least four inches thick poured around the casing and shall be provided with a watertight seal. The floor of the pit shall extend at least two feet from the center of the casing in all directions. In all cases, the pit shall be sized to allow adequate working space. The casing shall extend above the floor for at least 12 inches. An insect-resistant well cap shall be installed. The surface of the floor shall be pitched toward a drain which has a minimum diameter of four inches and discharged by gravity to the surface of the ground in an area not subject to flooding or to a basement which is effectively protected against flooding. Drain openings shall be effectively screened to prevent the entrance of insects and rodents. The drain shall not be connected to any sewer or other drain. The pit shall have watertight, reinforced concrete walls four inches thick or equivalent which provide for an effective watertight seal against the floor. The top of the pit shall be a watertight reinforced monolithic concrete slab at least four inches thick, which shall be sealed with the wall so as to effectively prevent the entrance of water. The top of the pit shall not be more than six inches below the ground surface. A durable watertight manhole shall be installed in the top of the pit centered over the casing and effectively sealed with the top to prevent the entrance of water. This manhole shall be at least 24 inches in diameter. It shall extend at least three inches above the surrounding ground surface and be covered by an impervious durable cover of concrete, steel or equivalent material which overlaps the manhole vertically by at least two inches. The manhole cover shall be effectively secured to the manhole by bolting, locking or equivalent means and shall be kept so secured. Pit installations shall not be used in areas subject to flooding by groundwater or surface water or where the groundwater level rises to within one foot of the bottom of the proposed pit. Where pipes enter the pit, the annular space between the pipes and the wall shall be effectively sealed by a watertight permanent seal.

Pitless installations. Pitless installations are those installations where the casing terminates above the ground surface.

Where pitless installations are used, they shall be of a design which provides an effective seal against the entrance of groundwater or surface water into the well, access casing and into the piping leading to the pump. All buried suction lines shall be effectively encased, or otherwise protected to prevent external damage or contamination. Pitless installations must be so designed as to be structurally sound and to provide for ready removal of drop piping without excavation. The access casing shall be effectively protected against corrosion and shall extend at least 18 inches above the natural ground surface and to a point below the frost line. The ground level at this point shall be elevated above the adjacent ground level and graded to drain away in all directions. The top of the access shall be effectively sealed against the entrance of waters, insects and rodents. An insect-resistant cap shall be installed. The pitless adapter shall not be submerged in water or used in areas used by automobiles and other vehicles.

Where surface installations (i.e., hand pumps, pump rooms, etc.) are used a watertight, reinforced concrete platform at least four inches thick and extending for at least two feet in all directions from the center of the casing shall be poured around the casing to provide an effective watertight seal with the casing, or shall be made watertight with an effective permanent seal. The surface of the platform shall slope to the edges. The casing shall extend through the slab for a least 12 inches and shall be effectively sealed against the entrance of contamination. An insect-resistant well cap shall be installed where appropriate. All pumping equipment shall be protected against freezing. If a pump room is proposed, it shall be so sized to allow adequate working space.

Venting. Where venting is required, an overlapping cover or pipe with the opening facing downward shall be required. Such venting shall be effectively protected against the entrance of insects and rodents. An insect-resistant well cap shall be installed. In no case shall openings be less than 12 inches from the ground, or, in the case of pit installations, the floor.

Individual water supply system standard.

An individual water supply system shall produce not less than 480 gallons of water in a two-hour period, at least twice each day, 12 hours apart.

If the sustained yield of the individual well or individual well system is not capable of meeting the total individual water supply system standard, sufficient storage shall be required. Borehole capacity and/or a storage tank shall provide storage capacity.

Minimum yield for individual wells.

All potable water supply wells intended to serve as an individual water supply shall be approved for yield in accordance with this subsection. Replacement wells servicing existing improved properties may be exempt from this requirement or wells servicing new construction may be released from this requirement at the discretion of the Manager or his authorized representative.

The criteria for approval shall be a minimum well yield of one gallon per minute.

For wells with yields of two gallons per minute or less, a minimum of 400 gallons of storage capacity shall be provided. Borehole storage shall be measured from the pump level to the top of the static water column. Wells with yields between two and four gallons per minute shall provide the storage capacity required to meet the individual water supply standard described in § 26-303, Subsection 3J.

If the well does not meet the yield requirement of § 26-303, Subsection 3K(2), a second well shall be required. If the combined yield of this well system does not provide the required yield, the Department will allow the use of this well system, utilizing the appropriate release agreement, provided the well system meets the individual water supply system standard in § 26-303, Subsection 3J. The permittee may propose to construct additional wells in an attempt to meet the yield requirement.

The minimum well yield requirements set forth in this § 26-303, Subsection 3K, are deemed sufficient to supply an adequate quantity of water for normal indoor household or equivalent usage. A supplemental source of water may be needed to support outdoor or other nonconsumptive uses.

Licenses. Only Pennsylvania licensed well drillers shall install wells within Warminster Township.

Monitoring wells.

Due to the variability in the information to be obtained, groundwater monitoring wells shall not be subject to strict compliance with the isolation distances given in § 26-303 of these regulations. The construction of each monitoring well must first receive written approval of the Authority in the form of a permit. Each monitoring well must be designed to minimize potential contamination of the aquifer and to maximize the information obtained from each installation. Analysis and reports prepared on monitoring wells must be submitted to the Authority.

Continued upkeep and safe operation and maintenance of all monitoring wells shall be the ultimate responsibility of the property owner.

Whenever a property on which a monitoring well is located is sold or subsequently changes ownership, the Authority shall be informed of the change. All information regarding the owner and any entity responsible for operation and maintenance of the well, shall be kept current at all times.

The property owner shall be responsible to inform the Authority of the operational status of the well. This shall be required on an annual basis within 30 days of the anniversary of the original issuance date of the permit for each monitoring well.

When a monitoring well is no longer going to be actively used it shall be considered as an abandoned well according to § 26-302 of these regulations and is required to be sealed in accordance with the abandonment procedures given in § 26-307.

Failure to comply with the above requirements relating to ownership, reporting and the operation, maintenance or abandonment of any monitoring well may result in legal action being initiated against the property owner by this Authority.

Test wells.

Test wells require a permit and must meet the isolation distances and construction standards of § 26-303 of these regulations for water supply wells.

Test wells are temporary and therefore are not permitted as permanent supply wells. Once the intended use of the well has been completed, the well shall be considered abandoned according to § 26-302 of these regulations and shall be sealed according to § 26-307.

Test wells may be converted for use as a permanent supply well. To be converted for use as a supply well, the owner shall submit a new application and the applicable fee for a new well permit to the Authority and meet the requirements of § 26-310 of this Part 3. Forms required for test well conversion are available from the Authority.

The converted test well will not be granted approval for use until the required forms and a water quality analysis showing that the water meets the requirements of § 26-311 is submitted to this Authority. In addition, documentation that the supply well meets the individual supply system standard in § 26-303, Subsection 3J, and minimum yield requirements in § 26-303, Subsection 3K, must be submitted to this Authority prior to well approval.

Failure to comply with these regulations regarding test wells may result in the initiation of legal action against the property owner by this Authority.
