C.4 Specifications - Borehole Drilling

C.4.1 Borehole design and construction

Though the final design of each borehole will be determined based on site specific design information on the formation, for the purpose of this contract a typical multiple casing boreholes in unstable formation above aquifer zone are considered. Drilling will be carried out at the location agreed with USAID’s representative within the area where studies have been conducted and have established a high probability of yielding a productive borehole. Drilling will commence at larger diameter and surface casing is set through the overburden and sealed by pressure grouting, drilling will continue at a reduced diameter through the unstable zone. An inner casing will be installed through the unstable zone and drilling will continue at reduced diameter. Further reduction in drilled hole and casing will continue as required to case off several unstable zones above the aquifer. Finally, a uniform diameter steel casing and screen assemblies will be lowered into the borehole and all larger diameter casings are recovered, apart from the grouted surface casing. The annular space between the completion casing and the borehole wall is then back filled and grouted at the surface.

Sampling

During the process of drilling, rock/soil samples shall be collected every 2 meters and as the lithology changes, for further analysis, identification of the water-bearing zone and to make decisions regarding the setup of the blind and screen casings. The samples shall be stored in a graduated sample box designed for such purpose. The drilling report shall include detailed records of lithology, drilling rate and borehole construction.

Drilling method

DTH is the preferred method of drilling, however, the Contractor may use any rotary or mud drilling technique that he feels applicable to achieve the depth and diameter required, provided that the techniques used are those specified in his proposal or are approved by USAID. The use of lost circulation agents or any form of plugging materials that may ultimately affect the production capacity of the water bearing strata will not be permitted. Any drilling fluids additives must be approved by USAID.

Drilling diameter and depth

Drilling diameter shall be proposed by the Contractor and approved by USAID based on field conditions. Drilling depth shall be determined in the field by bail testing and other criteria as directed by USAID. Borehole drilling shall be classified as soft, medium and hard formation as defined below.

Soft Formation: shall mean unconsolidated sediments, like surface soils, alluvium and laurite sediments, unconsolidated volcanic material like volcanic ash, tuff, etc., and decomposed igneous indicted sedimentary rocks & metamorphic rocks.

Medium Formation: shall mean unconsolidated materials of grain size greater than cobble, moderately weathered rocks and moderately soft rocks

Hard Formation: shall mean fresh not weathered igneous indicated sedimentary rocks & metamorphic rocks

Water supply and auxiliary services for drilling The Contractor shall make his own arrangements for obtaining, storing, transporting and pumping of water required for the drilling purposes and for use by the drilling crew at their campsite. The Contractor shall provide light and all necessary equipment and auxiliaries for drilling or any other of the operation to avoid unnecessary delays and work stoppages.

Environmental protection of site Care must be taken in handling and storage of all drilling fuels, oils, greases and fluids on site, to avoid any environmental degradation. The Contractor shall dispose of any toxic materials, drilling fluids, and other additives, cuttings and discharged water in a manner approved by USIAD so as not to create damage to public and private property, and shall adhere to the set of “ Environmental Guidelines for Drilling and Test Pumping Operation” described below. The Contractor’s adherence to these guidelines will be closely monitored by USAID, and any infringement by the Contractor may render unacceptable the particular portion of the works to which it applies. The Contractor shall ensure that all his personnel are aware of these Environmental Guidelines and the consequences of not adhering to them.

C.4.2 Environmental Guidelines and Code of Conduct

Groundwater exploration and development work should be conducted in an environmentally and socially sensitive and responsible manner. These guidelines are intended to ensure that all parties are aware of the potential impacts of their activities, and carry out the work in an appropriate way.

These guidelines are intended as a written statement of intent for the Contractor to adhere to, and to which recourse can be made in the event of a perceived undesirable impact.

Contractors are required to familiarize all employees with the content and spirit of these guidelines.

i. Camps If and where field camps are needed, their construction and removal should be carried out along the following lines:

• Permission for camp areas must be obtained in writing from the relevant local authorities.

• Suitable latrines and other sanitary arrangements at the camps and sites where work is in progress should be availed to the crew.

• Access roads and the camp area should be sited to cause minimum disturbance. No trees should be cut down; use of firewood must be restricted to dead wood only and should not conflict with the needs of the residents of the area.

• No permanent structures should be built at the camp.

• The camp should be removed, the site cleared and cleaned of all debris, and waste and hydrocarbons at the end of the Contract and local authorities should be shown the cleared site.

• All rubbish (except for oils and other mechanical or chemical waste) should be buried or removed

• Waste oils, chemicals and mechanical wastes should be stored and removed to Government/Municipal designated sites or recycling plants.

ii. Human Relations

• People, water, land and livestock must be respected and protected;

• Access routes should not transgress gardens. But if found necessary permission to enter the gardens must be sought from the owner. Work should be done with minimal damage to fences, trees and crops.

• All conflicts/disagreements and any agreements, no matter how trivial, must be logged and dated, with details of persons involved and subject matter, in a book for this purpose at the base camp.

iii. Drilling Site

• Each drilling site should be cleared of all waste after use. Drilling waste (chippings and muds) should be buried. Waste oils, chemicals and mechanical wastes should be stored and removed to Government/Municipal designated sites or recycling plants.

• No spillage of oils or fuels should occur and if it occurs appropriate methods should be used to clean the site to environmentally acceptable standards.

• During drilling and pump tests, the site must be protected from erosion by the erection of check dams, if needed.

• On completion of each borehole the site must be left clean and free from all debris, hydrocarbons and waste, and all pits filled to the satisfaction of USAID.

C.5 Blind and Screen Casing Material

Unless specified in the bills of quantities, uPVC blind and screen casings are specified they shall confirm to ISO 12818:1992 Standard with threaded male and female ends.

Internal Diameter (ID) Wall thickness

150mm (6”) 7.5 – 8.5mm 200mm (8”) 10.0 – 11.2mm 250mm (10”) 12.5 – 14.0mm

Screens shall conform to the same standards specified above. Screen slots arrangement, openings and type shall be submitted to USAID for approval before installation. The total opening area should not be less than 10 percent and the openings shall be 1 to 2.5mm

Casing Installation

The Contractor shall provide to USAID data obtained during drilling regarding the depth and thickness of the water-bearing zone, the water struck depth/level, and the static water level. Based on this data, the Contractor shall propose the number and position of screen casings, which USAID will approve or decline. The screen casings and blind casings shall be of the same specification as specified above.

The Contractor shall ensure that the borehole is cased throughout its depth, with a small (1-2% of the total depth of the borehole) allowance for settling.

All casing shall be joined by screwing them together, screwing should move easily without force thus ensuring verticality is maintained. To strengthen the joints, the outer side of joint of all steel casings shall be welded with 4mm metal strip to connect adjoining casing. A proper casing shoe, approved by USAID’s supervisor shall be fitted to the bottom of the first casing before lowering.

Casing installation shall not be done in the absence of USAID’s supervisor.

Observation Pipe Installation

One water level observation pipe should be installed in each well to be drilled. The observation pipes should preferably but not necessarily be 3/4” diameter GI pipe. The observation line should reach approximately as deep as the bottom of the housing line or as determined by USAID. The bottom most observation pipe shall be slotted at a distance 2m above the bottom and thereafter slots shall be at an interval of 10m. Each slotted section (screen) shall be 2m length. The uppermost slotted section should be 10m below the static water level.

If observation pipe screens are made by hand, slots may be cut with hack saw. Slots may be arranged on two opposite sides in an alternating manner. The slot spacing on each side being about 2cm apart, and care should be taken to ensure the slots are clean and without residues. Drilling holes or torch-cuts are not permitted

It must under all circumstance be installed in the borehole in a rectilinear way to allow the free passing of probes. Noncompliance with these requirements entitles USAID to not accept the well.

Well Plumbness/Verticality and Alignment Testing

Drilled boreholes will be tested for verticality and alignment by means of running a dummy down the casing. The dummy shall consist of a cylinder 10m length with a diameter 20mm less than the well casing. The dummy must pass freely through the entire length of the cased borehole. In the absence of a dummy, testing will be done by running two iron discs at least 3mm thick and of equal diameter or no more than 13mm less than the internal diameter of the borehole casing. The iron discs shall be connected from their centers by at least 3m of steel pipe of at least 25mm diameter. The dummy or the discs and pipe will be supplied by the Contractor and will be lowered to the bottom of the borehole by means of a steel wire passing over a pulley suspended from the machine winch or tripod and connected to the exact center of the dummy or the center of the top disc. The discs should easily pass down the whole depth of the borehole. The deviation of the steel wire connected to the center of the dummy or top disc from the center of the borehole shall not exceed one quarter of the internal diameter of the borehole casing. If these requirements are not met and if the borehole is determined more than 3% out of alignment, the Contractor will, if possible, correct the defects. If not, USAID has the right to reject the borehole and no payments will be made for its drilling and completion.

The contractor may also conduct these and other tests he may deem necessary to keep the borehole being drilled vertical and straight. These shall be made entirely at the contractor’s own expense

The contractor will report result of measurement and calculated deviation within 24-48 hours after each measurement. Six (6) days after the last measurement in each hole, the contractor shall prepare a report with summary table of instrument readings and calculated deviations. The results will be attached to the report

Well Development and Gravel Packing

In addition to the cleaning and development of the well before casing installation, the well will be developed continually during filter gravel packing. Washed and well-rounded river gravel, of diameter range 6-9mm and uniformity coefficient in the range 2.5 – 5 will be packed between the annular space of the casing and the well from the bottom until 6m below the ground surface. To avoid bridging of the gravel, which may lead to severe damage of the permeability of the aquifer or damage the borehole wall, it is forbidden to fill–in gravel by mechanized equipment. The gravel shall be inserted into the borehole by hand using a shovel.

After packing is complete, the well will be developed by air-lifting, alternating continuous and surging, for a minimum of 24 hours. During well development, the position of the air outlet (bottom of the drill pipe if drilling apparatus is used for air-lifting) shall be in the blind casing below the lowest screen casing and the Contractor shall ensure that the casing string is adequately supported at the top if necessary and is not damaged. Any casing and/or screen damage during installation and well development shall be the responsibility of the Contractor, who shall make the necessary corrections/repairs without additional cost to USAID. The airlift well development shall proceed systematically from top to bottom until the water is clear to the satisfaction of USAID’s supervisor. When well development is completed, the gravel packing will be topped up if it is found settling below the required depth.

Well development and gravel packing shall not be undertaken in the absence of USAID’s supervisor.

Pumping Tests

Test Pump Unit

The test pump unit shall consist of an appropriate submersible pump with a capacity determined by USAID’s supervisor based on the estimates of borehole yield determined from airlift or a bailer. The pump shall have appropriate number of stages to make it adequate to tackle the dynamic head. The test pump shall have an appropriate power source (generator) to run it, pipe on which to set the pump and all necessary tools and equipment to carry out pumping tests with an accurate measurement of water discharge and water level in the well. A turbine pump unit, run by an easily throttled diesel engine with the capability of discharging the estimated discharge range is considered advantageous over other types. For measurement of water levels in wells, electric water level indicators shall be used. The equipment and crew shall be as stated in the bid document, capable of performing the test pumping to the satisfaction of USAID’s supervisor.

Water Level Gauges: The contractor should have on the site at least 2 electric gauges suitable for maximum depth of borehole. The device should fit into the observation pipe and should permit direct, convenient and accurate reading of depth of static and dynamic water level.

Test pumping methods

Two types of pumping test shall be undertaken once the borehole is completed and developed. After measuring the static water level, a constant rate pumping test and recovery measurement shall be undertaken using an appropriate electrical submersible pump and generator for a minimum of 24 hours, although the duration can vary according to the rate of the drawdown. The recovery test shall continue until a minimum of 90% recovery is achieved. The discharge shall be measured using a suitable-sized water containers and a stopwatch, with suitable time intervals agreed beforehand with USAID. The Contractor will follow the instructions of USAID’s supervisor regarding the duration of the constant rate pumping and recovery tests.
