storm water drains

There are two main types of stormwater drain inlets: side inlets and grated inlets . Side inlets Side inlets are usually found adjacent to curbs and have an opening underneath to capture water flow. They are usually depressed at the invert of the channel to produce rapid water extraction. Grated inlets Grated inlets bars are spaced adequately so that the flow of water is not impeded, but sediment and many small objects can also fall through. To combat this HCL often integrates the use of extraction and disposal pumps. Soakaways Another option Hydro Cleansing can install is a soakaway system. These are mainly designed as a solution to standing surface water flooding. They consist of a large hole or pit that receives surface water from a drainage pipe and helps the water to slowly percolate through the soil, preventing a greater volume of water and reducing the risk of flooding.

Culverts are common on all types of watercourses and are critical infrastructure for field and farm access. But if undersized or poorly installed, culverts can be a problem. Every watercourse structure will require periodic maintenance. Culverts often become plugged or their capacity reduced because of debris or vegetative material. Headwalls may need occasional maintenance to prevent erosion and collapse. In conducting maintenance activities consider: Timing Limitations: When water is present, culvert maintenance shall only occur when flows are low. Debris or vegetative material can be removed by hand without timing limitations to prevent the need for larger repairs. Maintenance work on culverts in modified natural watercourses are subject to approval by the appropriate management body. Headwall repair should take place during the dry season when the work can be completed out of the water. If water is present when removing large quantities of debris, vegetation or accumulated sediments, additional measures must be taken to minimize impacts to aquatic life and water quality.
