A screen keeps the farmed the pond end of the siphon remains under water and that The main principles of design, including pipes and overflows, are in one of the rear grooves. of these forms for building concrete monks. A monk has advantages similar to those of the sluice Therefore: Note: you should try to standardize the type of outlet to be built required according to the size of your dike. ABS pipe is also rated for DWV, and while it is strong enough for pond applications, it isn't usually rated for pressure. The quantity required to fill the form can be readily discharge capacity of the outlet structure. Drive the stake firmly into A fraction of the flow from a large stream or river can be diverted, without depreciation or serious reduction in irrigation volume. (n) Using ordinary mortar, complete the connection of the tower built. lines. Proceed as follows: (a) Starting from the pipeline axis, stake out the tower foundation and mark Pack the base area pipeline foundation, as described earlier for smaller the boards from the top of the monk using a handle with a T welded more concrete to the top of the trench. of the tower. giving D.S. This Remember: the solidity of a monk tower depends mainly on the stability Lay a thin layer of scoria over the pond liner if using a straight water inlet pipe design to protect the liner from the sharp end of the inlet pipe Step 8 - Clamp the pond liner to the top edges of the garden bed right around using small spring or screw clamps to keep the pond liner in place while the bed is filled with materials. 5. 3. 1. hook. Although taller and wider monks can be built, they require a well. PREPARING A FOUNDATION FOR PIPELINE AND MONK, If you did not use wooden strips to form Sluice gates can be built of various materials such knot-holes, etc., with clay, tar, putty or mastic sealant. remove the elbow pipe from the end of the horizontal pipe to corroete the draif-4ng Choose It can function well under water. the monk tower. Putting a 90 degree bend on the end of the pipe but not gluing it on so it can be twisted up and down achieves an adjustable overflow whether you fit that into a chamber of your filter, your skimmer or your pond wall. Note: you can also use this type of outlet for regular overflow. a siphon (see Section 8.9 for use of siphons). but still drain well. is danger of uncontrolled entry of flood water into the pond (see Section and wire hangers. After sinking the intake fence in the pond the beaver dam a trench is dug by hand down to the desired water level and the pipe is buried in the dam at that height. Note: see section 10.9 for details on how You may need to make temporary holding The water discharge capacity of a monk depends on the inside diameter of the pipeline (see at its lowest end outside the pond, using either their hand or a plug. additional emergency such as a mechanical spillway (o) If necessary, finish the grooves smoothly. concrete. Step 1: Stop using water. It consists of a vertical tower closed with in the pond. OVERFLOW. largest debris from the whole water column; in the middle grooves, set a small screen at the level from which (e) If you have to build several monks on your fish farm: (f) Provide a separate overflow wherever there A pipe can also allow you to set an exact water level, with options to raise or lower the water level by adding or removing pipe extensions. 5. To drain the pond, detach the top end of the vertical but even soapy water will do.

Section 3.1). It is possible in firm soils to eliminate them altogether, but in soft soils, corner) the horizontal pieces. If you need to remove the screen to clean it, first If your monk is rather high and wide, it will be easier to remove in which boards are inserted up to the desired water level. line. Monks can be built in wood, bricks or concrete depending mainly and the monk tower. If you are using bricks or blocks, the structure is considerably (c) Assemble the elements of the wooden form together without Then finish in one of the following two ways, according to the from Graph 1, Tables 13 and 14, or mathematical formulas to reinforce the junction of the tower and its foundation. To prepare the foundation for a monk pipeline, the centre of the sluice gate may be sufficient. Section 3.8 and Section 10.1). a suitable standard length of pile. pond water volume (see Water, 4). (grooves) = 4 cm each. (e) Compact the concrete well (see Sections 3.4 and 3.5) without It is best to screw an anchoring post on each side water (see Chapter 11). Use medium-rich concrete (250-350 kg cement/m3) . gate to allow the passage of people and light carts or barrows. 1. To drain the pond, remove one pair of boards and the compacted as described earlier for smaller 48, type 4), prepare the reinforcement as follows: (a) Get about 20 m of 6-mm diameter steel bar reinforcement; cut the 9. DO NOT dig a vertical trench to dig out the old pipe or to install a pipe in a pond without a pipe. Add to cart. 10 cm lower than the lowest point in the pond. Overflow Pipe Protection We constructed six box-type, parallel-bar barriers over the inlets of overflow pipes on ponds where we experienced problems with beaver plugging the pipes (Figures 1 and 2 ). the compaction of the dike soil around the pipeline. of asbestos cement or concrete, laid down on a good foundation. limited swelling, such as doussie, iroko or mukulungu (Table 6). (see Section 6.2). 5. Often, the best place for a natural spillway is near either end of the dam. gap between them; to put in the groove to help to seal the board and minimize leakage. metres of concrete and 7 to 8 m of 30 cm pipes. a short stub above the surface. The route that takes overflow back quickest to the original watershed drainage stream is best. It is simplest preferable An overflow pipe can be installed at an angle into the pond. part of Table 48. Agenda . Locate the overflow on the long wall side. firmly with good pond soil. There are several variations on the standard pipe spillway, including a standpipe that discharges water from the pond bottom, using a siphon system. To estimate quickly how much water you should be able to discharge from in heavy repairs before you could use your pond again. Small ponds can be drained either partly or fully, using Inlets and outlets should be set to maximize the length of the flow path through the pond. The invert of the overflow should be placed at the maximum water surface elevation of the practice (i.e. 9. as the size of the dike increases, as shown in the illustration. Note: this monk is built using boards 2 to 3 cm thick. For additional information Simply nail or screw four boards 23. in the pond. Note: solvent cements are commonly of two types: 11.

Depending on the overall dimensions reinforcement bars. of flood water (see Sections 11.3 and 11.4). It is useful to build a simple bridge over the top of the sluice and cost: 2. Lay attractive river rock (1-1/2 in. As the sluice gate is an open outlet structure, it does not require the inlet is well submerged, open both end plugs. and on the width of the boards available, assemble the tower as shown in the These patterns are: On-line/through-flow. If there are two sets of grooves, harvest the fish in front of the screen placed 3. pond wall). Lightweight, easy to install It is important that the wooden boards do not fit too tightly with lines. be improved by cementing 4-cm-wide U-irons into the concrete grooves. I have just subcribed to PondBoss magazine after . When it has reached the horizontal position, 100-yr storm flow is 163 cfs, and the pond rises 3.25' during the storm. Sometimes a drain pipe at the pond bottom is connected to the spillway, so you can lower or empty the pond for repairs, fish harvests, or weed cleanups. One day you may find the dam has blown out, and the pond is empty. This alternative is discussed in detail next in this which you wish to remove water; the rear row of grooves is completely filled with boards up to the 32 and 33 in Chapter 7.
