Treatment and Supply Module

S Purpose To provide safe drinking water for up to 40,000 beneficiaries in emergency situations.

S Capacity S The module has the maximum capacity to treat, supply and store up to 600,000 litres of water per day. S The water quality meets WHO/SPHERE drinking water standards. S The module comprises two identical treatment and supply lines that can be erected on adjacent or different sites as the situation requires, plus four bladder tanks for separate water storage if required (i.e. at a clinic). (Each supply line provides for 20,000 beneficiaries).

S Principal tasks S Raw water is pumped from a water source to large storage tanks where sedimentation takes place. S The water then passes to a further tank where chemical treatment is carried out prior to being distributed via flexible pipework to tapstands where the beneficiaries can draw the water. S The module caters for a distance of up to 250m from water source to distribution points with the distribution points located up to 160m apart. S The module has been designed to enable local requirements (i.e. ground profile, water source types) to be accommodated. S The distribution system may be gravity fed or pumped. S The distribution system can include cattle watering and fire fighting. S It is intended that this module will be erected quickly using trained technicians. However, spares are supplied for up to two years use and adaption equipment is supplied so that the system can be developed if required to form part of a larger water treatment centre for long term use.

S Sub-Kits The module is made up for a number of sub-kits. Each is individually boxed, complete with all necessary pipe and fittings, , spares and instruction sheets required for their assembly on site.

S Indicative staffing patterns 1 team leader (Wat-San engineer) 4 general technicians (technician, plumber, electrician, chemical engineer) 1 logistician (optional)

S Average weight and volume Module complete: Volume: 45m3 Weight: 11,000 kgs. Single line: Volume: 26m3 Weight: 6,000 kgs.

Note: Treatment chemicals are classed as hazardous cargo. Only initial treatment chemicals are sent with the equipment so local purchase will need to be organised.

When considering the deployment of this module, consideration should be given for also deploying a Mass Sanitation Module

TS8 Pump Installation Instructions

Pumping from a water source to storage

1. Pumps are supplied with foot-valves, coarse strainers and reinforced flexible suction hose. The length should be kept as short as possible in order to increase efficiency. Cut hose with a hacksaw as square as possible to aid fitting to connectors. Push the hose fully on to the connector (using pipe grease as a lubricant) and fit the clip close to the end of the hose. It is important that the washer supplied is used with female hose couplers and that PTFE tape is used to seal all threaded joints. All joints on the suction side of the pump must be completely air-tight otherwise the pump will not operate.

2. The delivery connection to the storage tank is made entirely using flexible hose. If connecting to a storage tank the inlet may be made by using the standard 3” flange connector assembly, to which the hose may be coupled directly, or, as shown here, by passing over the rim of the tank.

3. A gate valve is provided to act as a throttle if it is wished to reduce the pump yield because of insufficient inflow to the water source. This valve will also aid in priming the pump if it is closed after pump operation and opened after restarting. A non-return valve should be included to reduce back flow through the pump.

4. It is very important that the pump is securely fixed to the ground. This is best done by casting a concrete slab, preferably at least 150mm greater all round than the base plate and at least 150mm thick to avoid cracking. The anchor bolts supplied with the pump should be cast into the slab. Alternatively, the pump may be bolted to heavy timbers, which are themselves pegged to the ground. The packing case bottom sections are designed as temporary foundations and can be used initially. The inlet and outlet hoses should be supported close to the pump in order to prevent damage to the connections through vibration. These supports should be put in place as soon as possible unless the installation is temporary.

TS9 5. It is always preferable to exploit ground water sources, as these are naturally better protected from contamination than surface sources. This pack can only be readily used for ground water sources where the water level will not drop below 7m from the surface when pumping. The static water level, when pumping is not taking place, will be above this. The pump should be fixed a small distance from the well to help prevent contamination of the water by fuel and oil spillage and to maintain the stability of the well. The strainer should be suspended just above the bottom of the well in order to avoid sucking sand. The foot-valve provided has an external diameter of 80mm and can be used in shallow, cased tubewells just greater than these diameters.

6. If no groundwater source is immediately available, a good alternative is the exploitation of a surface water source by filtration through bed sediments. This can be done, as shown here, by constructing a well in the bank of the stream and making sure that this is connected to the stream bed by a continuous sand layer. This method may yield water even when there is none evident on the stream surface, as much is stored in the sediments.

7. Where no alternative exists it may be necessary to use a surface water source directly. In such cases it is inevitable that the water will be contaminated and some form of treatment will be necessary, either by simple chlorination alone or combined with settlement which may be followed by filtration. Water may be pumped directly from rivers or lakes with the coarse strainer set on the bed provided that a primary screen is improvised, for example by use of a gravel-filled, perforated drum, to avoid inflow of sand. Silt intake can be reduced by floating the intake clear of the bed of the river, suspended about 0.5m below the surface, anchored against strong currents. The pump must be set above the river flood level.

8. This kit may also be used to pump water around a distribution network. Distribution by means of gravity is much simpler and should be used whenever possible but on very flat sites pumping may be the only choice.

The kit contains all fittings necessary to connect into a 3” PVC main. Hose connections to the pump are made in the same way as in 1 and 2 above, using metal fittings. Plastic fittings can be used for connection to the main.

TS10 9. It is essential to provide a relief circulation loop in order to relieve pressure when water collection valves are closed and the pump is in operation. This comprises a length of 32mm diameter polyethylene pipe connected by a compression fitting into a threaded tee at the outlet from the strainer next to the storage tank. All threaded connections must be made air-tight by use of PTFE tape on the threads.

Commissioning, Operation, Safety and Maintenance Information Commissioning After completing the installation, including fixing the pump securely and supporting the suction and delivery hoses, ensure that the suction hose is well submersed in water. Fill the hose with water and prime the pump by filling with water through the priming hole in the pump outlet. Close the discharge valve. Follow maker’s instructions, shown in the engine manual (enclosed with the kit) for commissioning the engine before attempting to start.

If the pump does not operate within five minutes from first starting the engine, re-check that all pipe joints on the suction side are air-tight as any air in the hose will prevent satisfactory pump operation.

When the pump is operating adjust the yield to suit both demand and the supply available at the source. Minor adjustments maybe achieved by changing the engine speed, but, if this gives insufficient reduction, use a throttle valve on the delivery side of the pump to introduce an artificial increase in head. After making such adjustments lock the speed control and remove the hand wheel of the valve to make sure that they cannot be tampered with.

Shading is particularly important in hot climates as high temperatures reduce engine efficiency. Ensure that both initial and regular maintenance of the pump and engine is carried out according to maker’s instructions by a competent mechanic. Regular replacement of oil, fuel and air filter elements is essential, as is changing of engine oil. Check the level of engine oil every day, or more frequently if running for prolonged periods. Keep the engine speed to the minimum required and ensure that fuel used is clean and that it is filtered by use of the funnel provided when filling the tank.

The following lists the sequence of operations and checks to be made in order to start the engine: C Starting any diesel engine can be dangerous in the hands of an inexperienced person therefore, before starting, the operator must understand the engine controls and have been instructed in the correct starting procedures. C Ensure the engine is free to turn without obstruction. C Check that the fuel and lubrication oil levels are correct C Ensure the fuel system is primed. C Move the decompressor lever(s) towards stop and hold in this position. C Move the engine control the RUN position. C If a variable speed control is fitted, move the speed control lever towards the fast position. C Crank the engine really fast and when sufficient speed is obtained, move the decompressor level down and continue to crank until the engine fires, retain a firm grip on the starting handle and remove it from the engine. C When a speed control is fitted, reduce the speed as required. C Stopping the engine, move the engine control to STOP and wait until the engine comes to rest. Warning: Never stop the engine by using the decompressor lever or valve damage may occur.

TS11 Operational Problems

The most common problems occur on the suction side of the pump. The most likely causes are lack of pump prime or blockages. Lack of prime is due to air getting into the suction house, which may be caused either by leaking joints or by lack of water at the source. All pipe joints should be regularly checked but beware of over-tightening plastic fittings. If the source is being pumped dry adjust either the pump yield or the daily pumping periods. Check regularly that the foot-valve is operating satisfactorily and is not being blocked open by sand and gravel. Cavitation damage can be caused to the pump by running with air being sucked in.

Blockages may occur at the suction strainer due to sand and silt when pumping from the bottom of a well or river. Either build better screening protection around the strainer or suspend it above the bottom. When pumping from a river the strainer may become blocked by vegetation. This can be avoided by use of a screen combined with regular cleaning. Beware of completely emptying tankers and running pumps dry. This can cause serious damage to the impellers.

Ensure that the engine fuel tank is kept regularly topped up with clean fuel. If a diesel engine runs out of fuel it will be necessary to bleed the fuel system to rid it of air.

Erection Instructions The instructions below relate to 45,000 litre tanks. Refer to the end of this section for additional instructions on 70,000 litre and 95,000 litre tanks.

1. Select a site that is fairly level and firm enough to support a full tank, so that interconnected tanks can utilise their maximum storage capacity. Look for a site that is well clear of trees, to avoid problems of roots, falling branches, leaves and canopy drip (which often brings with it living organisms). Where possible, site tanks on high ground or on a small, well constructed earth platform to allow distribution by gravity. If several tanks are to be grouped together, before starting any work, you should carefully consider the layout to ensure that spacing and relative heights will achieve what you want the tanks to do

2. Where an earth platform is required, it can be constructed using hessian/plastic grain sacks covered with plastic sheeting to stabilise the sides, though permanent installations should use concrete or masonry walls to stabilise a well compacted soil core. Ideally the sides of the mound should be inclined at no more than 450 and there should be a space of at least 1 metre from the edge of the sacks to the tank sheets to allow for working room as well as platform stability.

3. When positioning tanks directly on the ground use a stick and string to mark out circles of 4.2m radius and within this circle clear away all vegetation, roots, boulders and stones. It may prove necessary to cut or fill to produce a horizontal surface but, if so, ensure that areas of fill are well compacted and protected from erosion.

Using the same centres, mark out circles of 3.2m radius and on this line dig out a narrow trench about 50mm deep into which the bottom ring can be set. (This prevents the liner squeezing out underneath). If the ground is soft and clayey, dig out a 200mm deep trench and backfill 150mm with stones and gravel to support the steel sheets.

TS14 4. If sand is available, spread a layer up to 50mm deep to cushion the liner and prevent damage. Otherwise ensure that the ground is smooth and free from all sharp projections.

5. Place liner on the ground in centre of circle. Ensure that no oil or petroleum is in contact with liner (which causes damage as well as contamination).

Choose direction of link pipework and lay first ring sheets around circumference with pipe holes in chosen locations. Use the sheet with the blanked off hole in second (upper) ring unless using alternative draw-off arrangements. .

6. Working in pairs, one person inside and one outside the ring, stand the first sheet in shallow trench and bolt the next one to it, keeping all bolt heads on the inside. Overlap with one end inside, the other end outside. To align the sheets, first use the podger (spoke) and insert bolts at top and bottom of sheets. Then insert remaining bolts. Do not fully tighten any bolts at this stage. Once the first ring of sheets is assembled use a spirit level on each joint to get it vertical and then the rest of the tank can be built up correctly from this.

7. Complete first ring of sheets and then erect second ring. Stagger laps. Choose position of blanked-off hole to be suitable for overflow outlet, if used. Tighten all bolts only when both rings are completed. When tightening, check that sheets fit snugly and that any dents or sharp edges on the inside of the tank that could damage liner are flattened or filed smooth.

Continue building rings until the full height required is reached (T70 – 3 rings; T95 – 4 rings).

Finally, on inside of tank cover joints between sheets with strip of self-adhesive tape (to protect liner).

TS15 8. Fit smaller size of split PVC capping round top of sheets. (Bend capping back to open up split then roll on and press down evenly round rim). Trim off any excess at the join. Tape capping to tank at 500mm centres.

9. Installation of flange assembly is done in two stages:- Stage 1 (see step 16 for Stage 2). Take the flange with the threaded 3” diameter pipe welded to it and, having cleaned their threads, screw 4 studs into the threaded holes so that they project 50mm on the same side as the pipe. Use 2 nuts locked against each other and a spanner if necessary. From inside the tank, pass the assembly through the holes in the tank wall. Tighten nuts and washers on the outside, flattening the corrugations slightly. Pass the first rubber gasket over studs projecting inside the tank.

Choose the lowest tank and fit a flange to the blanked-off hole for the overflow pipework. (See step 21).

10.Backfill shallow trench in which steel rings are sitting, adding soil or sand to make a fillet on the inside to support liner. Use two workers with bare feet (sandals are provided for hot weather) or rubber soled shoes, free of any oily contamination, to unfold the liner inside the tank. Hands must also be clean. Carefully pull and smooth out the base area to fit as accurately as possible. The workers inside can, by leaning on the rim of the tank, kick the liner gently into the base of the wall. The seam in the liner between the circular base and the vertical walls should lie against the fillet of soil.

11.Attach the ropes to the eyelets round the edge of the liner. Pass the ropes over the rim of the tank. Directing operations from a ladder, position and number the rope controllers. Note: Although these drawings show sheets that are interwoven, the sheets can be simply lapped with the higher rings outside the lower.

12.Start lifting the liner from the inside with the slack being taken up by the controllers on the outside to prevent it dropping back. Do not attempt to pull the liner up by heaving on the ropes from the outside.

TS16 13. Continue to lift the liner, working from a platform of about half the height of the tank, taking care to protect the liner from the pressure of the platform. Continue until the liner has passed over the top and a short distance down the outside.

14.Secure the liner in position with the plastic capping and spring clips. Release the control ropes progressively.

15.When the tank is complete, the liner seams should hang vertically and not stretch when the floor/wall seam is pushing into the corner.

Stage 2 16.With the liner correctly positioned and not under any tension, cut four small circular holes in the liner by pressing it against the end of the studs and cutting around them carefully with a sharp knife or scissors. Slide the liner over the studs and against the first gasket.

Now pass the second gasket and plain flange over the studs and wind PTFE tape on to the studs (to prevent leakage), before tightening on the inside nuts. Finally, cut the liner round the inside of the plain flange, leaving a 3” diameter outlet hole.

Fit overflow pipework at this stage if using it (See step 21).

TS17 Roof Erection

17.Screw the eye bolt on to the end of bolts joining upper and lower rings of tank sheets. Space equally round tank 4 to each sheet.

Assemble the support column from 2 pipe sections, connector and 2 flanged ends and stand column in centre of tank.

Tension equally to provide support for PVC cover.

18.Lift circular PVC cover over central column and support ropes. Tension cover over tank wall and secure to eye bolts with 6mm rope passed through eyelets.

19.When the tank is in use, one or more ropes can be released to allow cover to be lifted for delivery-pipe access but re-secure them after filling.

Finally, either tie 10 guy ropes to eye bolts spaced around tank and peg down or bank earth against outside of tanks to one-third of tank height.

TS18 Link Pipework Connections

20. Where three tanks are linked together in a group, the connections layout shown should be adopted. If, however, one tank is used on its own the following points still apply for making the connections.

Screwed connections: Clean dirty threads, file or trim where damaged. Wind on PTFE tape in a clockwise direction to ensure strong but not over-tight joint. Use strap .

Hose connectors: Use pipe lubrication and push well into hose, fit clip towards end of hose and tighten bolt very firmly. Use gasket when screwing female connectors on to 3” threaded male fittings.

Cutting flexible hose: Best done with saw as squarely as possible.

Valves: Will require a hole to be excavated in the ground to allow them to be screwed on to tank flange. Backfill hole soundly to support liner. Support hose locally to tanks or valves to reduce strain on connector joint.

TS19 21. The following fittings are included in the tank fittings kit to provide one overflow 22. The inlet to the tank can be made by hanging arrangement per three tanks: a length of green flexible hose or 2 elbows C 1 no. 3” BSP hex. nipple coupled to the hose over the edge of the C 1 no. 3” BSP female threaded elbow. tank. However, if this is not supported with a C short length of 3” PVC pipe threaded at frame, over the course of time it will bend the one end. tank sheets slightly at the top, which should be avoided. Alternatively, an inlet Remove the blanking plate fitted to the arrangement with a flange and perhaps also chosen overflow outlet. Fix the flanges as a float valve could be used. Provision for this described in steps 9 and 16. On the inside of has not been made in the kits and extra the tank, screw in the nipple, elbow and pipe fittings would need to be ordered as required. as shown. Mark pipe 100mm down from level of rim of tank, unscrew, saw off and replace. Use PTFE tape on all final screw joints to avoid leaks. Finally, connect 2m to 3m of hose to outlet flange, discharge overflows safely away from base of tank.

TS20 The Water Distribution System

Each line comprises:-

Distribution Pipework Kit, 6 tapstands plus 180m of suction/discharge hose with a Spares and Adaption Kit, which will allow connection to almost all other systems likely to be found in the field.

The diagram layout shows general set up. However, the pipe lengths and positioning of the tapstands must be decided on site to suit the local requirements.

TS22 Layout Options for the Distribution Main.

1. Where possible, natural ground slope should be used to achieve a gravity flow with sufficient head available at each distribution stand. Pipelines should be laid as near as possible to a continuous slope.

2. Where the ground is flat, gravity flow can be increased by elevating the storage tanks. A compacted earth mound can be constructed by building soil up to 2m in height. For temporary works, use of hemp/plastic grain sacks covered with plastic sheeting will help to stabilise the sides of the mound, though permanent installations should use concrete or masonry walls to stabilise the soil core. Ideally the sides of the mound should be inclined at no more than 450 and there should be at least 1.0m from the inside edge of the sacks to the tank sheets to allow for working room as well as mound stability.

Where gravity supply is not possible, a pumped distribution system should be used.

3. A simple branched distribution main is often used as it provides the best access to the water points for the pipe available. The length and number of distribution stands should be determined by the needs of the population, but within the constraints of ground slope and pipe availability. Where high flows are required, more than one line of 3” Ø main may be used. In all cases the 32mm Ø branch pipes may be located at any point on the main but the length of the branch should be limited to 10m where the lack of pressure head is a problem, in order to keep friction losses to a minimum. A capped outlet should be provided for drainage and the strainer should be installed at the inlet to the main.

4. Where a distribution or pumping main has to be built quickly, 90mm PE pipe can be unrolled and laid directly on the ground without digging a trench. Coils should be placed at the highest end of the pipeline. Then the coil straps should be cut one at a time, starting at the end of the pipe, taking care that the pipe does not spring out when the straps are cut. Next unroll the pipe by holding one end in place and rolling the rest of the coil down the hill like a wheel. At a later date, when time permits, a 400mm deep trench can be dug next to the pipe and the pipe can be laid in it and backfilled.

5. The coils of pipe are connected by using compression fittings. It should not be necessary to take the compression coupling apart when making the joint. Simply clean and lubricate both pipe and coupling and loosen the coupling. Push the pipe in until it has reached the back of the coupling. Make sure that it is well past the rubber ring. It is also important to have the ends of each length of pipe lined up well so that they go squarely into the compression fitting otherwise there will be a tendency to leak.

TS23 6. The flange and gate valve are supplied with the water tank fittings. The other fittings (the hex nipples, strainer, hose connector and clip) are part of the Distribution Kit. Connect the strainer next to the tank outlet gate-valve and connect the strainer to the pipe by means of the flexible hose which will allow for any relative movement between pipe and tank. The hose may also be used to make changes in direction in the pipeline. The hose is connected to the pipe by means of a hose connector and a male thread to compression joint coupling (see figure 7). As this hose has a pressure rating of only 2 bar it should not be used in situations where this is likely to be exceeded.

7. Compression joints are used to connect the pipe to threaded fittings and these are fitted as in (5) above. Make all metal threaded joints with PTFE jointing tape and tighten with strap . Do not over-tighten plastic threaded joints.

Water Distribution Frame and Branch Connections

Water distribution points are very prone to becoming muddy from water spillage, which could constitute a health problem and be inconvenient for users. Particular care needs to be taken to ensure that this problem does not arise. The first step is to ensure that the frame is well sited, preferably on higher ground and on a slope, to encourage good drainage. Then the appropriate location to make the connection on to the main can be selected. Where pipe quantity/technical considerations dictate that distribution stands have to be grouped together, preferably no more than four should be positioned at one location. Large groupings of distribution frames do not encourage good community management of water collection points. Ideally the community should be consulted on this matter because the distribution point is the end user point.

8. Place the distribution stand upside down on the ground; screw the four legs into the sockets and tighten with a wrench so that the base plate is pointing away from the frame. Screw the 1” GS down-pipe into the centre of the distribution stand from the underside. Turn the distribution stand the right way up. Screw 3 the six /4” extension pieces into the frame.

The other end of the 1” down-pipe is already attached to the 1” galvanised 900 elbow. The 1” Ø BSP (M) x 32mm Ø UPVC compression coupling can be screwed into this elbow, after which it can be fitted to the flexible plastic pipe.

9. Remove the thread protection and screw the six water-saving valves on to the projecting pipes, using PTFE tape to make a watertight joint; make sure that the valves sit vertically, once tightened up. If fewer valves are required, screw a plug on to the end of the pipe.

TS24 10.Connect the distribution stand to the main using the 32mm PE pipe. The coils of pipe should be unrolled rather than pulled out. Connect the pipe using the compression threaded couplings. Clean all threaded fittings and make joints using PTFE tape. If pipes need to be extended, compression couplings may be used. Bury the pipeline in a shallow trench. If there is a shortage of compression fittings then heat welding or threading the outside of the pipe and using GS sockets can be used as ways of jointing the pipe.

TS25 Bladder Tank System

5m3 and 10m3 bladder tanks are provided, together with relevant pipework to give the ability to accommodate remote storage (5m3 or 10m3 bladders) or limited trucking (5m3 bladders only).

Bladder Kit Outlet

Tee piece 3” pipe green Gate valve on each outlet

Bladder/Pillow Tanks Instruction Sheet Handling Instructions (1) Site Inspection Ensure that the ground is level and free from sharp objects.

(2) Tank unfolding Remove groundsheet from carton and lay on surface where the tank is to be located. Carefully remove the tank and roll out to present the main fill/empty ports at the correct side for filling/emptying. Ensure that the tank is free to fill without restriction. Couple up the hose assembly to the fill point or locate hose in vent, top centre of tank.

Pre-fill checks (a) Check all surfaces for damage (b) Check connector is closed if not to be used for filling (c) Check that the tank is located in the correct position for filling/discharging. (d) Check that all loose items are repacked and stowed adjacent to tank (repair kit, etc.)

(3) Filling If a valve is being used, ensure it is in the open position. Open vent cap to ensure safe filling.

Warning Pump water into the tank at a reasonable pressure, checking that no items become entangled during the pumping process, putting localised stress on the tank.

Support hose if necessary. Continue pumping until nominal volume has been metered in or until the surface of the tank becomes hard. Stop pumping, close valve and remove hose. Close the vent cap.

Tighten down restraints where appropriate making sure they are taut but without putting additional pressure on the tank. Conduct an inspection of the tank for leaks.

(4) Emptying Reconnect the hose, open ball valve and commence pumping.

TS26 (5) Folding Ensure that the tank is empty and that all fittings are secure.

Carefully roll the ends of the tank into the centre ensuring that all debris is removed from the tank surface during the folding operation.

Place the tank in the case. Clean groundsheet. Roll up and place in case.

(6) Tank cleaning (a) Cleaning methods The following notes should be observed concerning cleaning the tanks:- Hot water and hot air can be used where appropriate. Neither should exceed 700C. Normally, a mild cleaning agent (Milton) can be used to clean the tanks. Allow the solution to stand for at least 2 hours to kill any bacteria. For stubborn stains or biological contamination, an alkaline cleaning fluid can be used to a maximum of pH 11. Cleaning by abrasion rather than wiping should be avoided. (b) Tanks Attention should be given to tanks as soon as they are received in the stores. Inspect the tank for obvious damage and note for future attention. i) Punctures ii) Major abrasions/damage iii) Insecure and damaged fittings Either hang up the tank or place the tank on a convenient table or trolley Follow any other procedures laid down for sterilising the tanks. Wash the tank out with soap solution and then clean water. Use air flow to dry out the tank thoroughly. Do not put the tank into storage with any faults but investigate immediately any repair work necessary. If the tank is satisfactory, fold up tightly and pack into a clean dry case. (7) General Repairs Repairs can be carried out in the field according to the information included, with the repair kit. (8) Do's and Don't's Do Move the tank in its case Protect surface of the tank from sharp objects Empty before packing Dry tank after use

Don't Walk over tank when empty Over fill Drag, even on the groundsheet Drop the hose assembly or any sharp object on to the tank If the tank has to be moved in an emergency, empty the contents, roll up the ends until there is sufficient fabric to grip and lift the tank to its new location.
