Section 4: Scope of Work

BOREHOLE TECHNICAL SPECIFICATIONS

A) GENERAL NOTES

A1) UNDERSTANDING THIS SPECIFICATION

The following technical specifications apply to all Pact borehole drilling activities and will be applicable

in any contract awarded under this RFP. The terms and conditions applicable to the successful Offeror’s

work will be contained in the Contract to be signed by both parties, but will include these technical

specifications. If the Offeror does not understand anything written in this specification, they should

consult the Pact for clarification, whether during the proposal period or during project implementation.

Questions may be addressed in email form to tenderssudan@pactworld.org. All Offerors are requested to

familiarize themselves with the content of Sudan WASH Technical Guidelines and Manuals for

Boreholes. The above document may be requested from the Ministry of Water Resources and Irrigation in

Juba or can be downloaded as pdf directly from the ministry’s website at http://www.mwri-goss.org

A2) MATERIALS AND WORKMANSHIP

All the work noted in this specification must be carried out to the highest standard, using only the best

tools, machinery, materials and skilled workmen. Samples of all casings, screens and gravel pack material

to the quality specifications given hereunder must be shown to a representative of Pact WASH Technical

Manager or their representative for written approval before starting borehole drilling.

A3) STORAGE OF MATERIALS

All materials for use in the borehole construction must be stored in a safe place. If any material can be

damaged by water or damp then the place must also be dry. If any materials are damaged before use they

must be replaced. All PVC casings and screens should be stored in shaded places away from direct

sunlight and with the threaded end caped. Ordinary Portland cement should be stored in dry place.

A4) SITE IN CHARGE

The Contractor must employ an experienced and knowledgeable site-in-charge who must be on site to

supervise the borehole construction work at all times when work is being done. Such an individual must

be conversant with the hydrogeology of Southern Sudan.

A5) HYDROGEOLOGICAL SURVEY

Pact through its field staff will supply to the Contractor all the information available about the sites to be

drilled. It should be clear that this information does not hold Pact responsible for the locally different

hydrogeological conditions in the area to be drilled at each specific drilling site or for particular problems

the Contractor may encounter during drilling operations. Each Contractor will be expected to carry out its

own hydrogeological survey of the proposed drilling sites.

A6) DRILLING SITES

Pact will indicate the drilling sites and secure the required permission for the use of the land where the

contract is to be carried out from the Local Authority responsible for the area. The Contractor will be

responsible for all the damages occurring outside the allocated land.

A7) ABADONED OR DRY BOREHOLE

If the Contractor is not able to finish the drilling or has to abandon the borehole due to loss of tools or any

other accident or contingency, the Contractor will remove the casing or drive pipes already placed in the

8

hole and refill it with clay or concrete, at the Contractor’s expense. All material extracted from such holes

will be considered the property of the Contractor. In the case of abandoned and dry boreholes, Pact will

not pay for any of the work carried out.

A7) CLEANING OF THE CONSTRUCTION SITE

When all construction and pump testing work is complete the Contractor must remove any rubbish,

remove or flatten (as ordered by a representative of Pact) any piles of loose earth, cake of drilling fluid,

back fill the ‘mud pits’ and generally leave the whole area of the site clean and ready for use.

B) BOREHOLE CONSTRUCTION REQUIREMENTS

B1) BOREHOLE LOG

The Contractor will submit a detailed Pact Borehole Log with the following information: drilling rates,

the appearance of water (various water strike levels), soil sampling details and the types of rock found,

type and size of borehole casing, position, type and size of screen and other relevant borehole

construction (design) details. The Contractor will keep soil and rock samples taken during the drilling

operations in properly packed and identified sample bags and will make them available to the Pact WASH

Technical Manager upon request. At every 3m a record of type of soil or rock formation should be

recorded including colour, grain size and geological name. The Contractor will take at least one sample

every three metres of drilling and at every change in rock formation. Each sample should weigh a

minimum of 500 grams.

B2) CASING AND DIAMETERS

The drilling of each borehole will be carried out according to the characteristics specified in the Sudan

WASH Technical Guidelines and Manuals for boreholes with hand pumps using the correct drilling tools,

drive pipes, casing pipes, gravel packs and sanitary protection, based on the actual characteristics of the

aquifer formations. The casing pipe and sanitary seal should isolate each aquifer from other formations

which are considered unsuitable for the exploitation of potable water. The borehole design is to be

informed by the lithology before the casing pipes and screens are introduced into the borehole. All

casings and screens shall be 4 inches with threaded sockets at both ends (male and female).

B3) CASING AND SCREEN

The Contractor will supply all casing, screen and fittings for the proper casing of the borehole. Samples of

casing and screen must be shown to a representative of the Pact WASH Technical Manager before

installation. A capped bottom sump of 3m long should be provided at the bottom of the well.

B4) DRILLING EQUIPMENT AND DEPTH OF DRILLING

The Contractor may use drilling equipment capable of drilling to a depth deeper than indicated in the

borehole design for a given area. The use of rotary or down-the-hole hammer (air percussion) rigs is

acceptable. The depths indicated proposed for each site should only be regarded as a guide. If the actual

characteristics of the boreholes being drilled justify any change in these specifications, the Contractor will

request the authorization of the Pact WRAPP Management for such changes to be made.

B5) BOREHOLE PLUMBNESS AND ALIGNMENT The boreholes shall be plumb. This must be ensured from the onset of the drilling work.

B6) TEMPORARY LID

The Contractor will take precautions against the entrance of pollutants into the borehole, including

surface water, both during drilling and after completion of the borehole. For this purpose, the Contractor

9

will provide a lid to be placed over the mouth of the borehole at any time the drilling rig is not in

operation. The lid will be placed on top of the borehole on completion of borehole construction.

B7) ARTIFICIAL GRAVEL PACK

As is often necessary, an artificial properly graded gravel pack will be placed in the annular space

between the well and the outer face of the casing. Proper techniques will be used for the accurate placing

of this pack. Gravel Pack materials should not just be dropped without regards to causing the well

collapsing in some sections. The gravel to be used should be clean, borehole-rounded and the grains

should be hard, and of alluvial origin. The gravel size and type shall be approved by the Pact WRAPP

Management.

B8) SANITARY SEAL

All the boreholes shall have a proper protective sanitary seal cast in concrete grout (one part concrete to

one part sand) by the Contractor. The protective seal shall be placed from 3.5 metres below ground level

to 0.25 metres above ground and will occupy an annular space between the wall and the outer face of the

casing.

B9) PLATFORM AND SPILT WATER CHANNEL

All the boreholes shall have platforms. The apron of the platform is the standard design used in Southern

Sudan. Sufficient quantity of cement (minimum 6 bags per platform and drainage channel), sand and

aggregate with a mix ratio of 1:2:4 should be used to produce the concrete mix. A welded mesh should be

used to reinforce the structure and the drainage channel must be a minimum of 6 meters long and

reinforced with rebar to avoid settlement cracks.

C) BOREHOLE CLEANING, DEVELOPMENT AND TEST PUMPING

C1) BOREHOLE CLEANING AND DEVELOPMENT

Once the borehole construction is finished, the borehole will be cleaned of all mud cakes until water

becomes acceptably clear. The borehole will be developed by hydraulic surging (by means of a packer

piston or compressed air) for at least three (3) hours until satisfactory flow and clarity is reached,

stabilized and turbidity is less than 5 NTU. During development, contractors will proceed with static

water level measurement. The Contractor is required to have a borehole development compressor of

minimum capacity 10bars and adequate supply fuel and lubricants.

C2) TEST PUMPING

The Contractor must have a pumping unit capable of discharging 3,000 litres per hour of water, at the

borehole’s pumping water level. Immediately after borehole development, the borehole will be cleaned

and the pumping unit introduced into the borehole. The Contractor will communicate (three days in

advance) the date the pumping test is to be carried out.

The pumping test will consist of continuously pumping the borehole at the maximum discharge of 1,200

litres per hour for 4 hours followed by a 2 hour recovery test. The measurement of the dynamic water

levels will be performed according to the logarithmic timescale schedule normally used for test pumping

water boreholes. The Contractor will convey the pumped water at least 200 m away from the borehole

such that no pumped water will be left standing within a radius of 200 m of the borehole. The Contractor

will provide all the necessary equipment for this to be achieved. The Contractor will provide all the

necessary equipment (weirs [V-notch], pipes, gauges, etc.) for the proper measurement of discharge rates

and water levels. Draw-down and recovery data should be reported on the standard borehole logs

supplied. This result will inform the hand pump cylinder intake installation.

10

C3) BOREHOLE YIELD

After the pumping tests have been carried out, the Pact WASH Technical Manager or their representative

will compare the yield for such borehole with the recommended yield of 1,200 litres per hour minimum

for borehole fitted with hand pump to be considered successful according to the test results. Appropriate

drilling techniques employed by the Contractor and the actual needs of the community are other factors

considered in determining the success of a borehole. Motorized boreholes will always be recommended

when yields higher than 1,200 litres per hour have been attained after test pumping. Pact will only pay for

boreholes with sufficient yield for their designated purpose.

D) CIVIL WORKS AND PUMP INSTALLATION

D1) APRON AND DRAINAGE

The contractor will construct civil works for the borehole in accordance with GoSS

recommended design for borehole apron and drainage. Drawings will be provided in the contract

package. The main components will include circular apron around the pump pedestal and water

drainage channel that leads water into a hand dug drinking cattle trough. All specification for

concrete works will be provided in the contract.

D2) HAND PUMP INSTALLATION

Hand pump to be installed is India Mark II. Pump cylinder will be installed to the suitable depth

below the dynamic (pumping) water level determined during test pumping. The fitting of

pumping rods, rising mains and all other components will be done in accordance with good

engineering practice. Safety precaution measures will be undertaken during this work to avoid

injuries.

E) BOREHOLE PROTECTION AND DISINFECTION

E1) BOREHOLE POLLUTION

The Contractor will take maximum care to avoid the physical, chemical or bacteriological contamination

of the borehole water during construction. If water is polluted due to the Contractor’s neglect during

construction, the Contractor will be obliged to carry out all the necessary operations, at the Contractor’s

cost, to redeem the borehole from such pollutants. This may occur especially where mud or bentonite is

used as the drilling fluid and water for mixing these drilling agents is drawn from already polluted surface

water sources.

E2) BOREHOLE DISINFECTION

Once the borehole has been completed and tested, the Contractor will sterilize the borehole with a

chlorine solution yielding at least 50 mg/l of active chlorine in all parts of the borehole. The chlorine

solution may be prepared from calcium hypochlorite, sodium hypochlorite or gaseous chlorine. The

chlorine solution should stay in the borehole for at least four hours at the specified concentration.

E3) WATER SAMPLES

The Contractor will take two water samples for laboratory analysis after completion of the long pumping

test. One sample will be used for physical and chemical analysis in the following two groups:

(Group1: Electrical conductivity, pH, Turbidity, Faecal Coliform and Residual Chlorine).

11

(Group2: Arsenic, Chloride, Fluoride, Nitrate/Nitrite, Sulphate and Total Coliform )

Samples should be put in a clean and properly sealed and labelled (GPS coordinates, date, State, County,

Payam and Boma) plastic or glass container. Another sample for bacteriological analysis should be

collected in three sterilized and properly sealed containers. The volume of each container should not be

less than 100 ml. All samples should be handed to a certified laboratory as soon as they are taken. A

certificate of water quality should be attached to well completion report. It forms part of the precondition

for payment.

E4) SAND PARTICLE CONTENT

The water drawn out of the borehole will be deemed unacceptable if it has a sand particle content of more

than 5 g/m3.If the water is deemed unacceptable, the Contractor will make all necessary adjustments to

the borehole structure, at the Contractor’s expense, to meet this specification.

F) BOREHOLE COMPLETION

F1) BOREHOLE LOG

The contractor has the responsibility to submit accurately completed borehole logs with the available

information including GPS, well development results, test pumping results, photographs, well design,

hand pump installation data, static water level, total well depth, dynamic water level and the date of

starting and completion of the well, type of hand pump installed, etc. The contractor also has the

responsibility to submit complete logs for dry boreholes that are not successful. Two copies of complete

borehole logs will be provided by the contractor to Pact. One copy will be handed over to the MWRI data

base by Pact. Borehole logs must be entered to the correct understanding of the Site In-charge. The Site

In-charge must sign in their full names clearly. Any slovenly completed well log will be rejected by Pact

and payments for such boreholes will be withheld until the contractor corrects the log at their own cost.

Contractors must avoid whitewashing and crossings on the final well logs submitted to Pact as such logs

will lose their authenticity.

F2) PAYMENT

The contractor will be paid for all successful wet boreholes once the Pact Borehole Log form has been

verified and accepted by Pact. Payment schedules will be specified in the Contract. The final payment

will be made after a defect liability period to ensure the quality of work. The final payment will

be ten percent (10%) and will be paid after a defect liability period of two (2) months from the

completion of the project. At the end of the liability period, quality will be assessed by a Pact

designated staff. In the event that defects arise and the contractor fails to make repairs, the

retention money will be used to have the same done by a third party.

In-line with standard practise across South Sudan, no payments or percentages thereof will be

paid for dry boreholes. Offerors will be expected to perform their own comprehensive

hydrogeological/geophysical survey prior to the commencement of drilling.
