How do rainwater pits work? A stormwater drain is a “hole” for collecting water or the last reservoir that holds all the flowing water before pumping out the drainage pipes connected at a rate corresponding to the flow of water. It is designed to help reduce flooding in the local area and help water canals flow to the local stormwater drainage network.
- It should be done by professionals.
There is a good reason why professionals should install rainwater harvesting. If they do not install the correct type of hole and drainage system, they will not be able to do the job they are supposed to do. It does not make sense to save a few dollars on installation costs if rainwater still undermines your foundations or diverts to an area that damages another part of your property or neighborhood.
- Choose Modular or Custom Fit
The stormwater holes are available in sizes from 450 mm square to 1200 mm square to fit the pipe diameter of DN 900. The modular system includes a series of precast risers and lids to adjust the height and protect the grate. Custom-designed rainwater harvesting can be tailored to meet a wide range of requirements for a rainwater drainage network to build roads, newly established settlements, and commercial and industrial development. The height of the holes can be adjusted to suit the requirements of each depth (conversion rates) and can range from 500 mm to 3,750 mm.
- Safety
Safety is a top priority. It is important for all parties to consider safety requirements and regulations during installation, including wearing appropriate safety equipment. We recommend that this statement complies with applicable codes of practice, standards, and safety regulations. Employees should follow any safety advice given to the main contractor/installers.

Part of the precast concrete should only be raised using suitable lift clusters and at fixed lifting points. Each stormwater well is installed with at least two feet of water. All lifting equipment must be approved to lift a certain weight and be authorized to lift precast concrete parts. When safety measures and guaranteed use are made, it is the first step in an effective system.
- Landscaping – digging, foundation, and bedding
Before a stormwater runoff arrives at the site, the site must be adequately prepared by excavating the area to provide clearance to ensure sufficient working space near the base of the pit and be installed on a stable, dense foundation to avoid future depletion. In the event that any softening or loosening occurs in the following excavations, the soft/loose matter can be removed or replaced with a single-size aggregate.
The combined depth of the convertible material should be uniform and sufficient to ensure that the minimum specified volume is achieved. Once the foundation is solid, bedding of sand or stone should be placed over the foundation to the same depth. The sleeping area is designed to provide the same support throughout the downpour. Common admission is approved bedding covered with a thickness of not less than 80 mm on a ground foundation or 150 mm on a rock base.
- Lifting
All concrete stormwater pits are provided with cast lift anchors for safe handling. To prevent pressure and possible cracking of the concrete, all units must be operated using cast lift anchors and associated lifting rods (lifting clutches can be purchased or rented from an authorized source or supplied by a crane contractor).
A spreader beam is recommended for lifting to prevent crushing. Installers should only use marked lifting equipment. It is the responsibility of the installation professional to ensure that the lift clusters are available on site. All parts must be lifted from the delivery truck and placed directly on the prepared bedding. If, for some reason, temporary storage is required in the area, and especially in large holes, use logs when laying the hole in the ground.
- Pit installation (multiple segments)
Installation of multi-component holes requires the following steps: 1. Close the segments together using a non-abrasive grout approved by the site or product of the mastic type. Next, apply the sealant according to the manufacturer’s requirements. Make sure there are no spaces left. 2. Place the second part on top of the inserted part. Quality bond is obtained due to unit weight. 3. Leave the parts undisturbed until the end of the healing period according to the manufacturer’s sealant or sealant product requirements.
