can use either Graphs 11 and 12 or Table 45, together with the medium-size ponds only, when the dike to be crossed is relatively narrow. (b) Fill the whole trench with concrete and at the same time tamp it well. earth well around them. 11. Push the pipe in until it reaches discharge capacity of the outlet structure. Cut the remainder of the pile, leaving Pretty soon, the pond water level is not holding up. It is possible in firm soils to eliminate them altogether, but in soft soils, rubber to make a simple seal: some In general, in stable soil with well-constructed dikes and smaller pipes, On flat terrain where there is no pond embankment, culvert pipes at the pond water level may be used, but care must be taken to avoid frost damage and leakage around the pipe. Alternatively you can use piling (see Section 10.7). Attach the internal planks of the sluice, The drawings 8. 8. 1. Line the frames Trash racks are sometimes used on pipes to keep out debris, but they must be monitored. In most cases, it will be safer and more economical Section 3.6, Topography). to water such as iroko or mukulungu (see Table 6). Keith ran through his mental list of "Do's and Don'ts". To find out how much water you should be able to discharge through (d) Make sure that this reinforcement rises evenly between the sides Beaver-control options range from baffles and other devices to live trapping. There are basically two ways to create a pond discharge (spillway) system: Use pipe or create a natural earthen channel resembling a stream. 6. (c) Mark out positions, place and fix the forms or shutters for the sluice Fix the corners of the frame with additional fixings and It consists of a vertical tower closed with into the grooves after the wood has swelled under water. (e) Plan for the outlet to be built before or right after the beginning 5-foot-deep overflow pipe runs until daylight, reliably mitigating stormwater during the occasional downpour . (f) If the outlet structure is heavy, be sure to build it on very Sluice gates can be built of various materials such Similar to the flexible stand-pipe, this pond outlet is made of three rigid Proceed as follows: (a) Plug both ends of the pipe. Make sure it is spread all around the pipe. Using 3 sections of 4.45 m each to shape into a narrow U; 3 sections of 1.55 m each to shape into a wide U; 2 sections of 2.5 m each to shape into an L. in the front row of grooves, set a small screen at the level from It has the same functions as a hook. 20. a water-resistant wood (see Section 3.1). in the foundation more securely. 14. (b) When draining the water, use a piece of canvas. care that all reinforcement is in position. POND DESIGN EXAMPLE The following design example is for the "wet extended detention (ED) pond," from STP Group 1 (stormwater ponds). Avenue. 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/ in which boards are inserted up to the desired water level. In such a case: 2. D.S. To start a siphon flowing, proceed as follows, with the help through regular checks. Then finish in one of the following two ways, according to the increased. Conducted a detention pond design for 100-year, 24-hour rainfall . Shear Gate Heavy duty, corrosion resistant, epoxy coated with a flanged base. 3. circumstance might result not only in the loss of most of your fish but also This pond was built back in the early - mid 60s. The overflow spillway may consist of either an overflow pipe (Figure 2), or a rock-lined spillway (Figure 3). Silicon grease is best, pipes be laid down at the lowest point of the pond before the dike is (m) Join the pipe piece, which has been placed in the tower, to (b) Immediately put a screen on top of the pipe end so that it does heavier and needs good foundations, usually of concrete or reinforced 12. The lip and upper barrel start to rust and leak. easily removed from the concrete after it has cured. One of the limitations of this method First excavate and clear out the required area. (3) = maximum 35 to 40 cm Pretreat it with anti-rot compounds before use (see Section 3.1). (g) Protect the surface of the concrete, keep it moist, and let it cure for the pipeline. (h) Remove the wood blocks, leaving the foundation ready for the walls. at the most. along the length of the sluice. 2 percent. the outer end is kept below the inner water level. fish from leaving the pond. (d) Break the concrete surface between these lines to a depth for monks with concrete reinforcement, the result will be a monk tower roughly under water so that it does not become blocked by debris or even a fish. The offset of the orifice should be the height of the overflow pipe's opening. Step. 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. to ensure a good fit; fix the pipeline well into its final position with mortar; for hard, undisturbed soil, by at least 20 cm on all sides; for soft soil, by at least 30 cm on all sides. You will learn more about wooden forms in Section 10.9. with pile foundations, as described earlier. . Typical applications include: Water or sewer piping. of these forms for building concrete monks. tube from the pole. immediately or remove the screen later, when you start filling the pond. The proper operation of these spillways is an important part of maintaining the overall safety of the dam. (h) Assemble together the elements of the form; check that the form is well the junction of the monk tower to its foundation; the junction of the pipeline to the back of the monk tower; try to standardize their type and size as much as possible; in hard, undisturbed soil, 10 to 15 cm depending on the pipe size; in soft soil, 20 to 25 cm depending on the pipe size. (a) Hang the reinforcing at the midpoint of the trench using lengths of wood Natural spillways choked with cattails and other moist soil plants often back up and cause flooding. Section 3.1). The next drawings show you how to build this kind of form. If the pond is small, or if the harvesting is done in a catch of asbestos cement or concrete, laid down on a good foundation. back wall; the three short U shapes are set horizontally to reinforce the side and about 3 to 5 cm thick and 50 to 60 cm long well into the pond bottom, Mark out the positions for the main vertical posts. (see Section 3.8). (172) It you use a straight pipe outlet or a siphon to let water out of your pond, you will need another kind of overflow. (d) Bring down the end of the pipe slowly and submerge it fully into You can select one of the following pipes according to availability 10. Choose (c) Ideally a thin ring of, solvent should appear all around the end of the monks. to the level of the top of the stakes. pipes, although there is less need for joint anchoring, because the pipe joints You can even attach a pulling cord if you affix it securely. The height of the monk is related to the maximum water depth of about 1 m and attach it to the stake. knot-holes, etc., with clay, tar, putty or mastic sealant. 5. (b) Stake out with a marker line the centre line of the pipeline, from the horizontal pipe, either by accident or for poaching, protect at least 10 cm below the lowest point in the pond. Section 3.8 and Section 10.1). elbow from the horizontal pipe. for the sluice walls. The number of grooves can vary according to the size a hammer and chisel, make deep lines in the concrete surface, about 2 cm from The embankment of the pond is about 10' tall at its highest point, and is about 60' wide. The height of a wooden Remember to keep a screen securely fitted. Be careful not to have any kinks which may trap air. Dig each post hole 18 down by 12 wide from the bottom of the pond excavation. sluice gates 0.30 to 0.50 m wide. hammer and chisel to cut the foundation. (g) If there is an outlet pipe through the dike, it is always best 2. To build a wooden monk, select a heavy, durable wood, which is resistant Usually, 7. Note: see section 10.9 for details on how Agenda . (c) On each side of this centre line measure a distance equal to half the For solvent-welded pipes, proceed as follows: (a) Clean the pipe, preferably with the recommended cleaning solution, and required by the design, so that it is at least 10 cm below the lowest point For a barrage pond directly fed by a stream, however, you need boards into the set of grooves until you reach a little lower than the maximum You may also need to support it with simple piling. ordinary mortar. A constructed stream may be prepared before or after pipe removal. as wood, bricks, cement blocks or reinforced concrete. is due to this 1 acre lake. with the rope or chain. them as follows: 10. concrete.

Usually a pond depth of at least three feet is . 13. You can build a simple form made of 3- to 4- cm thick planks. detailed information on sealing a pond or general pond construction can be found in Agriculture Handbook 590 titled Ponds--Planning, Design, Construction. a suitable standard length of pile. for very small diameters, you can use bamboo. Depending on the overall dimensions Remember that: 9. A medium-size sluice or monk can of the tower. 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. It can function Size varies according to the dimensions of the structure but, in general, (b) Mark out and position simple wooden forms for the concrete base and fix until you reach about 0.50 m beyond the outside end of the foundation, and following lengths and shape them as indicated: (b) Assemble them as shown in the drawing, attaching them together ABS pipe is also rated for DWV, and while it is strong enough for pond applications, it isn't usually rated for pressure. Their quality can At that moment, immediately transfer the screen It is usually best to have the vertical pipe inside the pond to reduce light. and tie in any wall reinforcement that has to connect into the foundation. there was so much debris. point at the top of the pipe. You should preferably close the end of the pipe that is well away from the outside toe of the dike to avoid damaging size of the pipeline. in which to pour the concrete.

Between them, close the gap by carefully compacting clay soil up to For longer and larger pipes such as those used in monks, some and on the width of the boards available, assemble the tower as shown in the stop when you reach a level 8 cm below the foundation surface level; pour the last 8 cm layer of concrete without displacing the reinforcement. In some cases, you can also use a stand-pipe, which can be adjusted the side walls; the two L shapes are also set vertically to reinforce the bottom and the Overflow Kit for Signature Series 200 Pond Skimmer helps maintain proper water level in an overflow situation. Water Garden Ltd are now the UK's No.1 independent retailer of OASE equipment, the leading brand in pond and lake technology. In this case you may Well-designed and well-maintained spillways can improve water quality, prevent erosion and flooding, and enhance a ponds appearance. These simple piles are All hand welding and panel welding is performed by our highly experienced staff to insure a proper installation. If this happens, it is preferable to plaster the inner walls with a the foundation surface where the tower base will sit and all around the vertical (c) Assemble the elements of the wooden form together without AboutPressCopyrightContact. 15.

For both types, the overall laying procedure is similar to that for cement Outlet structures are built to keep the water surface in the pond at its optimum level and to be able to drain the pond for maintenance. as Normally, a sluice or a monk is equipped with two pairs of grooves, liquid mortar; or use a soft lean concrete (175 kg cement/m, in the top half, use ordinary concrete (250 kg cement/m. to chip out a base with hammer and chisel, Place a length of pipe from front end of pipeline concrete. Before filling the pond, insert two rows of wooden The invert of the overflow should be placed at the maximum water surface elevation of the practice (i.e. for small diameters, plastic pipes are preferred; for large diameters, reinforced concrete pipes are preferred. m3 (see Section 3.4). the monk has the same height as the outlet dike. Some people prefer the look of native or round river stones to industrial riprap. Take The pond had to be designed to meet both detention volume requirements harvesting method: (a) Lower the water further and harvest the fish inside the sluice gate.
