PRELIMINARY REPORT ON THE ENGINEERING ASPECTS OF PLANNING, DESIGN AND CONSTRUCTION

I INTRODUCTION

1.1 SCOPE OF REPORT

1.1.1   Lembaga Kemajuan Ikan Malaysia (Majuikan) propose to establish a Fresh Water Aquaculture Centre at Tanjong Tualang, Perak primarily to undertake works of a commercial nature. The Centre would also be actively involved in research and training of Majuikan personnel in aquaculture development. Initially the Centre intends to commence work on a commercial scale for culturing of fish and shrimp.

1.1.2   Preliminary aquaculture studies undertaken by Majuikan in conjunction with Fisheries Department have identified three (3) sites in the State of Perak suitable for fresh water aquaculture, however, from the engineering point of view the site at Tanjong Tualang was selected. The site chosen is part of an existing low/swamp ground bordering a major river Sungei Tumboh and at present Sungei Tumboh is known to support a large stock of wild shrimps.

1.1.3   Discussions have been held with Majuikan officials and other officials from different agencies to ascertain their requirement and criteria for the design of the shrimp and fish culturing ponds and other facilities in the Centre and this forms the basis for planning and layout of the Centre.

1.1.4   This report covers the engineering aspects of planning, design and construction of fish and shrimp culturing ponds, buildings, and infrastructure for the Centre.

1.2 TERMS OF REFERENCE

The Terms of Reference require the Consultants to conduct preliminary investigation, design and construction of the Centre and details of these are set out in letter of invitation for consultancy services enclosed in Appendix ‘A’.

1.3 ALTERNATIVE SITES FOR THE AQUACULTURE CENTRE

1.3.1   Three (3) sites, i.e. in slim, Kampar and Tanjong Tualang areas have been identified by Majuikan Official in conjunction with the Fisheries Department as being suitable for freshwater fish and prawn culture. The sites were visited to ascertain the suitability from the engineering point of view and details are listed in the below mentioned paragraphs.

1.3.2   Site No.1, Daerah Batang Padang, Mukim of Slim is located in a region where tin mining activity is currently in progress and this is a source of pollution of Sungei Slim from which we propose to obtain water for the culture ponds. The land available is only 50 acres and this is insufficient for expansion purposes. Also the site is located on both banks of Sungei Slim and access and control of the works would be difficult and would involve substantial initial cost for the bridge crossings. As such this site was generally not suitable nor selected for the construction of the pond complex.

1.3.3   Site No.2 at Kampar is situated about 16 miles from the town of Ipoh and located on the right bank of Sungei Kampar slightly inland and extends to the foothills. Most portions of the site is disused tin mining areas with large sections of it being stagnant ponds. The land avaialble is only about 100 acres and not sufficient for expansion purposes. Tin mining activity is noted in adjacent areas of the proposed site.

More than half the site is covered by existing disused mining pools and these have now been used by local farmers to rear fish on a TOL basis. The ponds are more than 20 feet deep with large amounts of rock outcrops in the pond areas. In the remaining areas some vegetable farming is being carried out.

The soil at site appears to be sandy clay with large sand content and appears not capable of retaining water above the water table. Five hand augers to a maximum depth of 3 feet have been conducted by Majuikan and the test results confirms to an extent the sandy nature of soil.

The water in Sungei Kampar is quite clear but at times the effleunt from tin mines are discharged into Sungei Kampar. The water level in Sungei Kampar is quite low in comparison to proposed site and pumping to lift water to the ponds would be necessary.

In view of the following facts this site is also not suitable for construction of the pond complex :

1. Insufficient land for expansion purposes;

2. Difficulty in acquiring land already given out on a TOL basis;

3. Expensive earthworks due to sandy nature of soils, presence of rock, existence of deep ponds;

4. Pumping is essential due to elevation of site in relation to water level;

5. Possible pollution of Sungei Kampar, the only water source.

1.3.4   Site No.3 at Tanjong Tualang is located along the 32nd milestone along the Tanjong Tualang-Kampung Gajah road near Sungei Tumboh bridge. Most of the areas is open grassland with patches of belukar and forms part of an extensive swamp/water logged areas. An existing earth track constructed by loggers forms the main access to the site from the main road. Some isolated tapioca growing was observed at site. Most of the site is state land and an extensive area is available for development purpose. It was also noted that this area was ear-marked for aquaculture development in the Trans-Perak Development.

The soil at site seems to be sandy clay with fair amount of clay and appears able to retain water. Stagnant patches of water were observed in many places in the other areas and the water table was quite high.

The main source of water at this site would be Sungei Tumboh, however, the normal water level is low in relation to site. Sungei Tumboh is fairly wide and deep and the water is turbid as logging and minor tin mining activity is still going on upstream. However, it is known that prawns and fish are abundant in this natural condition.

Among the 3 sites available it was generally noted that this site at Tanjong Tualang is more suitable for construction of Aquaculture Centre and the site was selected for further studies and investigation.

1.4 TOPOGRAPHY

1.4.1   Topography surveys were carried out at the Tanjong Tualang site and works included spot levelling within the site, detailing and cross-sectioning of Sungei Tumboh within the area.

1.4.2   The proposed site (for the initial phase) comprising approximately 100 acres is located in fringes of Hutan Simpan Parit and is situated on the right bank of Sungei Tumboh (see Fig. 1/1). The ground level varies from +18.00 M.S.L. to +25.00 M.S.L. and is presently under open grassland and belukar. Certain portion of the site are subject to inundation when the river water level rises in Sungei Tumboh. Sungei Tumboh is not subject to tidal effects or saline intrusion.

1.5 CLIMATE

1.5.1   The climate in this region is on the whole equable and continuously humid. The site is affected by the SouthWest Monsoons and rainfall records from neighbouring station indicate the average rainfall ranges from 84.99" to 119.98" (year 1965 – 1970) and 68.8" to 92.97" (1970 – 1975) annually. The mean raingall ranges from 106.41" to 81.55" and the greater part of the rainfall is during October through December.

1.5.2   The site is free from the effects of tropical cyclones or severe winds.

1.6 SOILS

1.6.1   The soil in the proposed site is of recent alluvial deposits and during the time of writing this report field and laboratory information from a recently initiated soil investigation programme indicate a layer of sandy clay 3 feet to 20 feet thick over-lying a coarse to medium sandy layer (refer soil profile Fig. 1/2)

1.6.2   Examination of the soil samples and laboratory test results indicate the soil is characterised by reasonable shear strength and bearing capacity generally capable of retaining water.

1.7 NEIGHBOURING DEVELOPMENTS

1.7.1   Discussion with other government agencies indicated that there would be substantial development activity in the Tumboh Block in time to come and most of these have been enumerated in the Trans-Perak Study. The upper catchment area of Sungei Tumboh has been ear-marked for cattle farming, cash crop cultivation and forest reserves.

1.7.2   For immediate development it is known that Jabatan Parit dan Taliair Perak (JPT) propose to improve the complete drainage system in the Tumboh area and topographical surveys for these have already commenced and this has to be taken into account in the design of the Aquaculture Centre.

1.7.3   The Jabatan Kerja Raya Perak (JKR) have already appointed engineering consultants to upgrade the existing logging track adjacent to the site and this is being done under the Accelerated Rural Roads Programme and JKR envisage construction works to be completed around late 1980.

1.8 DATA AVAILABLE

1.8.1   The data initially available and obtained from various Government Department include :

1. Topographical Map Sheet No.64 (Series L7010)

2. ) Standard 8 chain revenue sheets

3. Rainfall record for period 1965 to 1975 at station No. 3094, Kampung Gajah.

4. Water levels at Sungei Tumboh.

II SOURCES OF WATER

2.1 SURFACE WATER SOURCE

2.1.1   The only source of surface water at site is Sungei Tumboh, a fairly large river, however, its catchment is not well defined as it flows through swamp and water logged areas. Approximating the catchment area at 33.7 acres the flood flows and dry weather flows is estimated at 3135 cusecs and 12.6 cusecs respectively for a once in ten year frequency.

2.1.2   The once in ten year flood level is estimated to reach a level of +23.00 M.S.L. and at a similar frequency low flows is estimated at +10.00 M.S.L. The normal average water level record is +15.00 M.S.L.

2.1.3   The water in the Sungei is quite turbid with a high sediment load and a form of retention is necessary to settle a major portion of silt in suspension. Results of water sample analysis obtained from the Sungei is indicated in Appendix ‘B’.

2.2 GROUNDWATER

2.2.1   No information regarding groundwater is available at or around the vicinity of the site. Groundwater studies were not undertaken at site as these are generally expensive and pilot drilling for test wells, observation wells and testing would have to be carried to ascertain the availability and quality of groundwater. Also with the presence of large surface source of water, investigation for groundwater was set aside.

2.3 POLLUTION

2.3.1   At the moment the only form of pollution noticeable at site is the logging and minor mining activity being carried out in the upstream catchment. Further pollution is generally not expected if the development of the upstream catchment will be as outlined in Masterplan of the Trans-Perak Study.

III PLANNING, DESIGN AND OPERATION OF FISH/SHRIMP CULTURING PONDS

3.1 PONDS

3.1.1   Siting of Ponds

In order to take advantage of the easy access from the main road, minimum earthworks and to site the ponds in soils which substantially retain water, the area bounded by the existing main road, existing logging track and Sungei Tumboh has been considered ideal for siting of ponds. (See Fig. 3/1)

The ponds are located 2 chains away from the existing river reserve to allow for any drainage improvements. Also the ponds have been sited at a minimum distance of 1 chain from the existing logging track which would be soon upgraded.

3.1.2   Layout of Ponds

Discussion with Majuikan Officials revealed that for the initial phase 15 No. Nursery Ponds of ¼ acre size and 25 No. Culturing Ponds of 1 acre size each would be the minimum required at the Centre. A retention pond has been provided with a capacity of minimum 24 hours settling time to reduce the turbidity of water being supplied to the nursery and culturing ponds.

Nursery and culturing ponds are rectangular in shape with opposite corners rounded-off to facilitate uniform dispersal of water during times of supply and draining. The ratio of the height to breadth of ponds varies from 1:1 to 1:2.

The depth of the nursery and culturing ponds is 3 feet with central collecting channel about a foot deeper than the general level of the pond to enable draining and harvesting. Generally the collecting channel would normally be unstable and requires regular maintenance possible after each harvest.

3.1.3   The general elevation of the nursery and culturing pond bottom has been proposed at +17.00 M.S.L. and this has been derived by using normal operating conditions with average water level at Sungei Tumboh being +15.00 M.S.L.

3.2 DYKES

Dykes are constructed of material excavated from ponds. In this particular case there is insufficient spoil from excavation of ponds and selected imported borrow material would be necessary to supplement the excavated earth for dyke construction. Typical details of dykes are shown in Fig. 3/2. The side slopes of the dykes are maintained at 1 ½ : 1 slope. The top width of dyke are 4 ft. minimum and for dykes accommodating light vehicular traffic 10 ft. width is provided. Turfing would be essential to prevent erosion of exposed surface. However, suitable cover crop which could also serve as fish feed could also be substituted.

3.2.1   Perimeter Dykes

Perimeter dykes are provided as a flood protection bund around the pond complex. The height of dyke after settlement and shrinkage is maintained at +25.00 M.S.L. and is 2 ft. above the once in 10 year flood level.

3.2.2   Secondary Dykes

Secondary dykes are provided on both sides of the supply and drainage channels. The secondary dykes are designed to a consolidated height of +22.00 M.S.L. which is 2 ft. above the maximum water level maintained in the ponds.

3.2.3   Tertiary Dykes

Tertiary dykes form partitions between ponds. The consolidated height is maintained at 1 ft. higher than the maximum pond water level.

3.3 SUPPLY CHANNELS

A network of interconnected supply channel conveying water from spillweir at the outlet of the Retention Pond to individual ponds. The size of the channel are designed to carry water at the rate of 30 gallons per minute flow for each pond or to fill one of the culturing pond over a period of a day. In order to minimise losses in water and gradient the supply channels are lined. Details of supply channels are indicated in Fig. 3/3.

3.4 DRAINAGE CHANNEL

Earth interconnecting drainage channels (see Fig. 3/4) are provided to completely drain the ponds or drain away excess and or waste-water from ponds. Lining of drainage channels have been omitted to keep the initial financial outlay to the minimum, however, later these could be incorporated. The free drainage level is set +15.00 M.S.L. which is the average normal water level in Sungei Tumboh. Drainage channel are designed to cater for the draining of any one of the culturing ponds within a period of 3 hours or a continuous spill of 30 gallons per minute of circulation or waste-water per pond.

3.5 WATER CONTROL STRUCTURES

Spillweir, inlet and water control structures and drainage structures are provided in the group of ponds to regulate and efficiently control the flow of water in ponds.

3.5.1   Spillweir

A concrete spillweir to drain off the top layers of the settled water in Retention pond is provided before the supply channel network. Water passes through a graded course filter which is integrated with the spillweir. This serves as a predator control device. Frequent washing of filter media and replacement of filter media would be necessary to ensure quality and quantity of water.

3.5.2   Inlet Water Control Structure

Inlet water control structures are provided at points where water from the supply channel are introduced into individual ponds. This structure is a simple concrete/ masonry division box with precast concrete drop boards to allow water from supply channel to be diverted into concrete pipes which lead the water to the ponds. Typical details are indicated in Fig. 3/5. The structure has been designed to fill the pond within a period of a day.

3.5.3   Overflow-cum-Outlet Water Control Structure

Each nursery and culturing pond is provided with an overflow-cum-outlet water control structure. This structure is of masonry and reinforced concrete pipe construction (see Fig. 3/6). Excess water above the top water level flows over the side spill arrangement into a sump and is lead away by concrete pipe to the drainage channels. At the bottom of the sump a timber gate is provided to drain the entire pond. The outlet structure is designed to empty the pond within a period of 3 hours or to cater for spill of 30 gallons per minute.

3.5.4   Drainage Control Structures

Where drainage channel meets the perimeter dykes, drainage control structure (see Fig. 3/7) are provided to keep flood waters from entering the drainage system in the pond complex. Drainage control structures are constructed of reinforced concrete with inlet and outlet wingwalls and concrete pipe barrel with flap gates fitted on the external side of perimeter dyke.

3.6 PUMPED SUPPLY

3.6.1   The elevation of the pond bottom in relation to the normal water level is such that economic water management is possible only with a pumped sypply system. Heading up Sungei Tumboh with an enormous weir structure and the construction of leeves on both banks to contain the raised water level to maintain a complete gravity system through the nursery and culturing ponds is estimated at $1 million. This initial outlay is considered high and therefore this alternative of having a complete gravity scheme is not considered any further.

3.6.2   Water is lifted from the inlet channel leading from Sungei Tumboh into the retention pond for settlement filteration and distribution to the ponds.

3.7 CONSTRUCTION OF PONDS

3.7.1   It is envisaged that the construction of ponds and dykes would be mechanised. Stumps under dykes are not cleared as it stabilises the dykes, however roots and stumps in the pond areas would have to be removed.

3.7.2   Draglines would have to be used for general excavation and dyke building, and low ground pressure (1gp) dozers for levelling and trimming.

3.8 OPERATION OF NURSERY & CULTURING PONDS

3.8.1   The operation of nursery and culturing ponds necessitates filling of ponds and regular circulation of water. Draining and drying the ponds is also necessary to eradicate pests and predators, re-condition the pond bed, harvesting of fish/shrimps and also for routine maintenance. For the filling and regular circulation operations water management is totally dependant on pumped supply. Draining and wastewater flows is by gravity and the free drainage is +15.00 M.S.L. after which drainage is restricted due to high water level conditions in Sungei Tumboh.

3.8.2   Water is pumped from the channel into the Retention Pond wherein it is allowed to settle and the top layer of the settled water is taken over a spillweir through a coarse filter and from here it is distributed through a network of supply channels into individual ponds. The inlet control board for any particular pond to be completely filled shall be fully open. For allowing normal regular circulation of water the drop board is left partially open only. Circulation or excess water from individual ponds spill over the outlet structure into the system of drainage channel and eventually are led out of the perimeter dykes. When any particular pond is to be drained the timber gate at the outlet control structure is fully opened and the water in the pond is released into the drainage channel. Fine screens are permanently provided in the overflow area of the outlet control structure whereas a set of fine screens would have to be introduced while completely draining the ponds.

IV BUILDING, INFRASTRUCTURE, PLANT & EQUIPMENT

4.1 OFFICE AND LABORATORIES

The office and laboratories would be housed in the same building and is located close to the Nursery Ponds. A lean-to area for external work purposes is also provided at the office to receive fish and shrimp fry or fingerlings and for subsequent transfer to the Nursery Ponds, also this place serves for harvested fish/prawns waiting for collection. The structure shall be a single storey building of a combination masonry and timber construction and having a floow area of approximately 3,700 sq.ft. The office has been strategically located so as to be centrally located when further phase of the pond complexes are constructed.

4.2 STAFF QUARTERS

4.2.1   Staff quarters are located along the main road and access road and also near to the pond complex. The following number of staff quarters are proposed :

4.2.2   The quarters are single-storey buildings of a combination of masonry and timber construction and having the following floor areas :

4.3 ANCILLIARY BUILDINGS

4.3.1   Other buildings to be provided in the complex would include the following :

• 1 No. Store of masonry and timber construction (approximately 1,600 sq.ft.) for stocking chemicals, feed and etc.

• 1 No. Guard House of a masonry and timber construction (approximately 100 sq.ft.)

• 1 No. Timber Garage.

These buildings are to be located in the office compound.

4.3.2   Field Shelters

Timber field shelters are provided at the shrimp breeding ponds, to serve as rest areas for the field workers and also to serve as guard posts. These shelters of light timber construction could be easily dismantled and re-assembled at any desired location.

4.4 SERVICES

4.4.1   Roads

The internal road network in the office area and quarters area is constructed of selected imported earth fill materials and shall be paved for roads in the buildings and office compound and laterite surfaced for the other areas. The total top width of the road is 12 feet and side slopes are maintained at 1 ½ : 1 and turfed to prevent erosion. Road culverts and drains are provided where necessary for the proper and efficient drainage of the area.

4.4.2   Water Supply

Water supply could be tapped from the Jabatan Kerja Raya Main along the Tanjong Tualang/Telok Anson Road with the approval of Jabatan Kerja Raya.

4.4.3   Electricity

Electricity supply could be obtained from the LLN supply mains with the appropriate contributions and prior approval from LLN. Power would be supplied to all the buildings and lamp posts would also be erected at the pond complex, road junctions, office compound and quarters. A space has been allocated for the provision of an LLN sub-station.

4.4.4   Sewerage

Individual septic tanks with filter beds are proposed for each of the above-mentioned buildings.

4.5 PLANT/EQUIPMENT AND HARD FURNISHING

4.5.1   Pumping Equipment

For reasons mentioned in Section III, pumping equipment would be required and this would be housed in a building for better protection. These pumpsets would be mixed flow type with high capacities and low head lift. Pumpsets would be electrically operated with all necessary protection systems in conforming with Lembaga Letrik Negara and chief Electrical Inspector regulations. Three pumps are proposed to be installed; two of these pumpsets would be duty pumpsets while the third unit is standby, providing 50% of standby capacity.

4.5.2   The duty pumpsets have been designed to cater for a regular circulation flow of 30 gallons per minute for each pond or complete filling of a culturing pond within a period of a day under maximum head conditions, i.e. during low flows.

4.5.3   Hard Furnishing

A provisional sum is included in the cost estimates for hard furnishing for the office and quarters and these would have to be defined at a later stage.

V COST ESTIMATES

5.1 RATES

Cost Estimates have been based on 1979 current prices and adjusted to suit works of this nature.

5.2 MAIN ACCESS ROAD

It is assumed that the existing logging track adjacent to the site, which is also used as a means of access to the complex would be upgraded in the Trans-Perak Development and therefore these costs have not been included in the cost estimates.

5.3 COST OF WORKS

The total capital cost of works including the capital cost for installation of pumping equipment is estimated at $1 million and details of these estimates are given in Appendix ‘C’.

5.4 ANNUAL RECURRENT MAINTENANCE EXPENDITURE FOR PUMPING PLANT/EQUIPMENT

The annual recurrence maintenance expenditure for operating the pumping plant have been estimated at $8,000.00 and details are shown in Appendix ‘D’. In estimates, allowance has been made for pump attendant operating the pumpsets, however, no other labour or administration costs for other aquaculture needs have been included at this stage.
