storm water drains

HCL’s experienced team provides our expert groundwater remediation services to all types of storm drains. Our team provides rapid water extraction from surface water flooding, rainwater removal and construction dewatering using our flood water removal pumps. These high-powered flood water removal pumps mitigate further damage by pumping out excess rain and groundwater from watertight surfaces like paved streets, car parks, and roofs.


Storm drains are vital at helping prevent flooding by diverting rainwater and melted snow off the streets and other paved surfaces into a natural body of water or water treatment works


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.


it's true about what they say, out of sight then out of mind, but if you’re a homeowner and your underground drainage from your property is connected to the public sewer network, then you have to pay for the privilege of using it. Responsibilities for repair or maintenance on various drainage pipes across your property boundaries are deemed to be your own responsibility. This has been further complicated by rules changed in 2011 with the new Private Drains and Sewers regulations, it’s worth checking to be sure exactly where you stand as a property owner or spoon to make a purchase..


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.
