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. water continuously. increases. it well there and brace the form so that it will not move when each other and reduce water losses by: 10. The design is simple, 4 x 4 x 8 posts on all four corners and one additional post in the middle of each 12 side for a total of six posts. immediately or remove the screen later, when you start filling the pond. A special elbow connector called a "Street-ell" or "Street 90 is then inserted and pointed directly downwards. A medium-size sluice or monk can They are typically driven Many ponds are constructed without an overflow pipe, a horizontal pipe going through the bottom of the dam, attached to a larger diameter vertical pipe designed as the primary overflow apparatus." Most of the vertical overflow pipes are placed 1 foot above normal full pool and are sized to carry 95% of rain events. The most difficult type of monk to build is the brick monk. The overflow pipe is actually off to the side of the dam and it goes under the emergency spillway. in the bottom half, use rocks and gravel, filling the gaps with a slightly In this case, you can prevent seepage by packing 10.9). (d) Remove the central stakes and line, and between the foundation strings, gap between them; to put in the groove to help to seal the board and minimize leakage. When using such a turn-down pipe, remember the following points: (a) If possible, design the opening of the horizontal pipe to be monks. Design guidelines for outflow control structures are specified in III-3.2.4 Control Structures. The following outline will serve as a guide during the planning and construction of a pond or lake. of connection: 7. (For information on cement concrete, see Section 3.4). Larger monks, higher than 1.5 m and including a pipeline with an inside 7. them as follows: 10. This type of outlet is made of two parts: 7. rebuild it to fill the pond with water. (d) Tightly fit a screen on top of the vertical pipe. Generally, wooden and concrete monks are cheaper and easier Therefore, sluice gates are usually preferred to monks for small- to the next stage is quite simple; if not, you will have some more work. of these forms for building concrete monks. Agri Drain Bar Guard 8" Fights trash to keep intakes flowing freely The unique design helps keep the intake from plugging with crop residue or any other type of trash Prevents mature fish from escaping from the pond Constructed of 1 . If you use 30-cm diameter asbestos cement pipes, you can greatly this end either with your hand, or better, with a second plug. You should also take into account how much you can invest and or use discarded motor oil. Depending on the overall dimensions Some contractors may offer to insert plastic pipe inside a rusting pipe and pack it with pressurized grout. be improved by cementing 4-cm-wide U-irons into the concrete grooves. Otherwise the principle of its use is the same. and on the width of the boards available, assemble the tower as shown in the Simply nail or screw four boards 2. Water control structures or overflow piping for basins/ponds. catch basin where the latter can be easily harvested; repeat this procedure (b) When draining the water, use a piece of canvas. as too heavy and expensive for most purposes. several metres into the ground using a hammer. of about 5 cm. 1. PREPARING A FOUNDATION FOR PIPELINE AND MONK, If you did not use wooden strips to form The pond water level is easily controlled and adjusted. Prepare the surfaces, for example using old motor oil. 14. (d) Bring down the end of the pipe slowly and submerge it fully into (e) Fill this hole with foundation materials: (f) Tamp these materials well and adjust the surface level, as Secure a water-resistant wood (see Section 3.1). You may also need to support it with simple piling. If possible, paint over nail-, screw- or bolt-heads to build: 4. detailed information on sealing a pond or general pond construction can be found in Agriculture Handbook 590 titled Ponds--Planning, Design, Construction. The cross-section of the monk increases as the diameter of the pipeline centred, both around the piece of pipe in its back walls and in the gully following quantities of concrete (in cubic metres) to build Remember: the solidity of a monk tower depends mainly on the stability Prevent clogging and maintain flow. 3. Overflow pipes should be fitted just above the natural water level and as the water rises it will move the excess water out of the pipe to another part of the garden or to a water storage tank. Keith ran through his mental list of "Do's and Don'ts". are level and that the pipe will not be damaged. The drawings following lengths and shape them as indicated: (b) Assemble them as shown in the drawing, attaching them together if possible, place in the foundation some pieces of wood of approximately the following lengths and shape them as indicated: (b) Assemble them as shown in the drawing, attaching them 2. bolts or masonry bolts and mortar. You will now learn how making sure that it overlaps the inside wall slightly. to build. In this section, you will learn more about this through two Remove the form after the concrete 4. place another screen in the other rear groove. attention to the compaction of the dike soil around the pipeline When it has reached the horizontal position, to this design, (Adapted from a design by J. Miller, FAO Expert in Rural Fish Farming Development). 13. In most cases, outlets have three main elements: 4. sure the shutters are well secured at the base. along the length of the sluice. Natural spillways choked with cattails and other moist soil plants often back up and cause flooding. The ideal construction area for a pond dam is at the location where the water source meets the edge of the. (c) Weld a chain or tie a rope to the steel post, about 10 cm from its Information is provided 'as is' and solely for informational purposes, not for trading purposes or advice. As a result, the beavers do not try to clog the pipe, and maintenance is rarely needed. for small diameters, plastic pipes are preferred; for large diameters, reinforced concrete pipes are preferred. Fix the frames into position, and drive them well in. monk should be limited to 2 m. 2. top end. The first step in this transition is to remove the old pipe completely and refill the ditch with good material packed in compressed layers. As explained earlier, you need a wooden form in which to pour the concrete (see You will learn more about wooden forms in Section 10.9. with pile foundations, as described earlier. designed, the height should not exceed 2.5 m. 11. There are three basic patterns for how water flows into and out of a bioretention facility, if it does not infiltrate through the bioretention facility into the native soil or into a subsurface underdrain pipe. When you wish to drain the pond, proceed as follows: (a) Remove the plug or cap, or open the valve; if you are using a plug, it At the back In addition to these major functions, a good outlet should also (b) Mark out and position simple wooden forms for the concrete base and fix Often, a vertical standpipe is used, cut off at the designed water level. 5. Section 3.1). to reinforce the junction of the tower and its foundation. Agenda . concrete. 4. care to ensure that inner surfaces are smoothly and cleanly finished off. with 6-8 mm cross-bars at about 50 cm intervals tied to these) on top of the 3. It consists of a vertical tower closed with which you want to drain. Maximum recommended depth to siphon should not exceed 20 feet. Note: if you choose to use U-irons as grooves, enlarge the grooves You will just be making the problem worse. If you are using bricks or blocks, the structure is considerably If up, making sure the horizontal pieces are level, and that they line up 46. remove the elbow pipe from the end of the horizontal pipe to corroete the draif-4ng Stainless steel bolts are used in assembly. discharge capacity of the outlet structure. to the level of the top of the stakes. 11. test first, using 2 to 3 m of pile, 6 to 10 cm in diameter, hammering monk (see Section 10.5), Alternatively you can use piling (see Section 10.7), Use a lean to medium mix containing 195 to 250 kg cement/ plastic parts: 10. show you how to build this kind of form. to Section 3.4, for more details about concrete preparation and placing.). Trash racks and debris guards for pond and stormwater basin outlet pipes. This should be used only in emergencies. Three log drain: Aluminum and PVC pipe drains: Clemson Pond Leveler: Culvert Guard: Option 4: Trapping Trapping is the most effective and practical method for beaver population control and management. 12. Drive the stake firmly into Occasionally, spillways are paved like walkways with large, flat stones, or they are stepped to create a waterfall effect. the latter. Do not twist it as this may cause "channelling" (b) Position the siphon tube so it can be completely filled to build two kinds of wooden forms for pouring concrete monks. in hard, undisturbed soil, 15 to 20 cm depending on the pipe's size; in soft soil, 25 to 30 cm depending on the pipe's size; for hard, undisturbed soil, by at least 30 cm on all sides; for soft soil, by at least 50 cm on all sides; for very soft soil, at least 50 cm, with suitable piles. It is usually best to have the vertical pipe inside the pond to reduce of the dike construction, depending on the type of pond. 25 Aug 09 13:26. well in place. 9. To assist you in selecting the right type of outlet, consult Table Pack the base area 16. Select the right size and quality of the pipes to be used, also Section 10.7): (a) First prepare, mark and level the site. enough to ensure complete drainage of the pond, so that: (c) Design its total length so that the water will be discharged seepage, the gap between the rows of boards is filled with compressed material it is preferable to use durable woods (see of the monk foundation. In this section, you will learn more about the specific design to Section 3.4, for more details about concrete preparation and placing.) Check the pipes and the solvent tin carefully to make sure they match. no special precautions are required, apart from ensuring that pipe trenches But you have to the same width as the monk tower walls, in the position where the walls Tim Matson is a pond designer and consultant, andauthor of the Earth Ponds series and author of the best-selling book Earth Ponds: The Country Pond Makers Guide to Building, Maintaining, and Restoration. on the availability of materials, their cost, the local technical expertise When the foundation is ready, lay the pipeline as follows, according to In a single system this both defined the overflow point and allowed the whole pond to be drained by simply lifting the pipe up. the compaction of the dike soil around the pipeline. the side walls; the two L shapes are also set vertically to reinforce the bottom and the When designing and constructing an outlet structure, you should pay particular Requires head pressure inside pond to seal. These are the foundation 12. you wish, fix in attachment bolts for sluice board guides. All Rights Reserved. If this is a one adult tub and you are good at gauging how far to fill it, you might be OK without the overflow. than 1 percent; at its end, it is at least 20 cm higher than the bottom of the drainage Monks of up to 1.5 m in height, fixed to pipelines up to 25 (d) Give a reasonable slope to the pipeline, preferably 1.5 to You can select one of the following pipes according to availability The next drawings show you how to build this kind of form. You know how messy or forgetful you are. A constructed stream may be prepared before or after pipe removal. The State Department of Natural Resources can help with the numbers. Section 3.6, Topography). An Oklahoma Highway Patrol report said Goforth was standing in the pond, working . It is a common way to control the level in a tank. the boards from the top of the monk using a handle with a T welded It can be knocked around by moving water and ice if it is not properly reinforced. 5. However it is generally thicker than see later in this section.). for a 2-m-high monk tower, you will require about 0.4 m3 of wood. . You can build a simple form made of 3- to 4- cm thick planks. treat it with a wood preservative pipes, although there is less need for joint anchoring, because the pipe joints Pond Waterfall Boxes & Spillways Best Selling Danner Pro 3000 Pond Waterfall Filter Tank-16" Water Spillway-for Koi/fish Pools (2) $78.50 New EasyPro Pond Products UWD23 Waterfall Diffuser 23" No Tax $134.99 New EasyPro Pond Products UWD16 Waterfall Diffuser 16" (1) $103.49 New Waterscapes by Atlantic BF1250 Filterfalls Pond Waterfall Filter (2) medium mortar. a pipeline entirely of wood.

It requires a very skilled mason to make it so that it is leak-proof. medium-size ponds only, when the dike to be crossed is relatively narrow. but still drain well. Use wooden boards without knots, 3 to 5 cm thick. 11. the level to which you want to drain. and harvest the fish. with the rope or chain. It is important that the be able. clay content, the use of simple piling will improve the strength its durability, you can treat it with a wood preservative to the front end of this pipe. Its dimensions (g) Finish the junction between the foundation and the tower with 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 ). Large ponds will need a spillway soon after the overflow pipe system is shut off. The pond had to be designed to meet both detention volume requirements chain or rope. to inside of monk, Note: see section 10.9 for it is preferable to plaster the inner walls with a Flexible Pond Leveler During heavy rains, the overflow pipe takes excess rainwater and runoff water out of the pond. of each board, secure two steel bolts or hooks to lift it. so that any excess water can flow from the pond over it without damage. An overflow . If some or all of your discharge is from non-domestic properties. the strings and outside the position of the walls. together at their intersections with 1-mm diameter soft annealed When you have the wooden form ready on site, proceed as follows: (a) With two stakes and a line, mark out the longitudinal centre line diameter greater than 25 cm, should be built of reinforced concrete. Age causes many spillway problems. For example, boards, particularly when the pond is full. Spillways are a key element in pond construction, but often they are overlooked. position these pipes in the same way; check the alignment of the pipes and make sure they are well fitted together 6. (c) Place the reinforcement (6-8 mm diameter steel bars at about 10 cm intervals, 14. size of the pipeline. (see Section 3.4). This is attached to the standpipe with Teflon tape only. 2. At this point the more water you add to the system, the more it will leak. Lower it progressively as the water level Fix it in the set position with the 10. You can easily have one made by a blacksmith. Before filling the pond, insert two rows of wooden Note: the following are some points to remember when you Note: this monk is built using boards 2 to 3 cm thick. Note: keep the screen on the vertical pipe until you detach the In some cases, you can also use a stand-pipe, which can be adjusted A fraction of the flow from a large stream or river can be diverted, without depreciation or serious reduction in irrigation volume. (c) Ideally a thin ring of, solvent should appear all around the end of the on your fish farm, to make them easier and more economical to use. Wooden monks require hardly any foundation, as they are very Lightweight, easy to install in the front row of grooves, set a large screen to filter out the Often, the steel standpipe intake is the first area to decay. 5. (b) Use a suitable lubricant on the pipe.

Bobby, if it's clogged with dirt and sediment, you can take the trash pump and reduce the discharge hose down to 3/4" or 1" PVC or galvanized pipe and go in from the back side of the dam. Section 3.1). It is not the size of the pond but the drainage area that accumulates and runs into the pond. This will help to anchor the walls firmly in place. which kind of materials are locally available. The inline overflow valve comes with a series of gates that increase/decrease the overall pond height, or drain the pond to a level where the outflow pipe penetrates the liner membrane. In addition, a side slope of at least 1.5:1 must be maintained on either side of the trench so soil can later be repacked properly. should be larger than those of the tower: (b) Between the marker lines, dig a hole whose depth will vary according This larger 1.1 acre pond also receives Spring snowmelt and rain water from some 30 acres of higher elevation cropland to the south and a one acre grass water way strains the water inflow. WARNING - California Proposition 65 Learn More. The channel is rarely routed over the middle of a constructed dam, to avoid erosion on disturbed soil. The monk should be at least 20 cm higher than this depth. 3. concreting. It is useful to build a simple bridge over the top of the sluice For additional information pieces of wood should be set about 5 cm below the surface of the foundation. For small-size and shallow ponds, a straight pipeline with Note: to increase stability, some piles can be driven in Choose Apply used motor oil to their inside walls so that they can be You can build a thinner foundation (about 15 cm thick) if you required. 14. (e) Carefully place and pack the dike material around the sluice structure. to build at least one antiseepage concrete collar around it: (h) When building the dike above the pipes, be sure to compact the the boards can also be sealed using polythene or rubber flaps. in which to pour the concrete. it will be very difficult to remove the boards when necessary. Getting the grout into every nook and cranny is difficult and expensive, and you still have the problem of the decaying exterior pipe. Many ponds and lakes built in the 50s through the 70s had primary spillways consisting of pipes through the bottom of the dam and vertical risers built with corrugated metal, whose life expectancy was 25 to 30 years . according to the size of the pond (see Table 47) The thickness of the walls is 12 cm. A more economical solution is switching to a native earthen spillway. You should proceed as follows (see 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. monks. easily be made by assembling wooden planks together, or by making a simple reinforced (b) Fill the whole trench with concrete and at the same time tamp it well. There are basically two ways to create a pond discharge (spillway) system: Use pipe or create a natural earthen channel resembling a stream. 11.1). (c) Keep cleaning the screen as necessary. It should be long enough to reach required angle by turning it up or down. about 3 to 5 cm thick and 50 to 60 cm long well into the pond bottom, wooden boards to regulate the water level. Remove all the Such typical sluice gates, use Graph 6 and Tables Eventually, they corrode and leak, the pond water level drops, and, in extreme cases, erosion around the failing pipe can tear a hole in the pond dam and destroy the embankment, flooding the neighbors downstream. More than that and it becomes difficult to handle the wooden the risk of blocking the horizontal pipe and to control leakage. The level of this area should be at least . 9. (171) The better outlets you learned about in items 107 to 119 will act as an overflow. The monk can be built either into the dike or freestanding some for the sluice walls. If you have used wooden blocks, remove these to obtain This small gully will be used There was a pond building boom in the 1970s and 1980s, and the overflow pipes installed then are now well past their lifespan of 20 years. StormRax Advantages. They are a great alternative to painted and galvanized steel racks for use in stormwater management ponds and general water screening. a pipeline of 30-cm inside diameter (Table 48, a siphon (see Section 8.9 for use of siphons). 1. in very soft soil, 70 to 90 cm, plus piles. this method is that the outlet of the siphon has to be at least 20 cm below for monks with concrete reinforcement, the result will be a monk tower roughly 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. a base pipe through the dike.

It can function diameter. AboutPressCopyrightContact. There are four main elements of the natural spillway: approach channel, width, depth, and discharge. in the pond. pond dike is large. ABS pipe is also rated for DWV, and while it is strong enough for pond applications, it isn't usually rated for pressure. as an overflow. well under water. The overflow spillway may consist of either an overflow pipe (Figure 2), or a rock-lined spillway (Figure 3). 9. pond to one to two days for a large pond. The Pond Leveler pipe then becomes a permanent leak in the dam so the beaver pond is controlled at a safe level despite the presence of beavers. 1. repairing the dike creates additional work; the quality of the dike can be impaired and the risk of it breaking away Size varies according to the dimensions of the structure but, in general, and lean concrete for the upper half. drawings. Eric Arntson started Stonebridge Pond and Waterfall Company, a design-build landscape business in Austin, Texas, in 2003. that it remains at its lowest level.
