Choosing a pumping station? Which pumping station is suitable for the site? Is a permit required? Can I do it myself? Is a design / construction plan available? We offer free remote mapping. In connection with the mapping, you will receive written information about the RAITA systems that are suitable for your use, and any authority permits. You can implement the project in whole or in part yourself. In addition to the mapping, we also provide assistance with planning, equipment installation and system construction. Look at RaitaPro’s.

Choosing the right Raita pumping station model? How to size a pumping station? The pumping station must be sized according to the maximum load. We are happy to help you choose a model - book a free remote survey. Look at RaitaPro’s. pump well diameter: – D400 - D600 – D900 - D1200- D1850 the volume of the pump well is determined by the water consumption of the site. The pump pumping capacity at the site / the required storage space affect the choice of diameter / the condition of the pump well. - get in touch - we will map out a suitable unit for the site. pump well height: our pump wells are “modular”. They can be delivered at different heights. Correspondingly, their height can be increased with an extension section (height 60 m). A larger diameter extension and cover can also be used to raise the well – f.ex the D600 pump well is “modular” – it can be delivered 220 cm – 150 cm or 77 cm high. Extension section D600 (height 600 mm). A larger diameter (D900, D1200) riser and cover can also be used to raise the well (which provides the exact height of the well, additional space in the upper part of the well (for the riser part. The riser of a larger diameter remains ground or, if necessary, is primed with cement casting. The additional space is used for installation of possible technical devices (heater, electrical connection devices, etc.) and to facilitate maintenance of the high well). Pump selection: The pump selection is based on the properties of the pumped liquid, the size of the pipeline, the distance and height to be pumped, the amount of water. - get in touch - we will map out a suitable unit for the site. Pumping station without or with backflow: – no backflow, affects the operation of the pumping station so that a small amount of water (from the pipe) always returns back to the well. The advantage is that the pipeline cannot freeze (thereby no water remains), the purchase saves the cost of a check valve (100-400 eur) no need to replace the check valve (need after 20-30 years). The downside is the pumping of the water that has returned to the pump well “again”. Often used when the distance is small (the amount of water that returns is small) and when you want to ensure that it is not frozen. – with a backflow, when the distance is large (the amount of water that returns is large - over 10%) anchoring and installation of the pump well - see https://raita.com/maa_asennusohje.pdf pump well for sites with high groundwater our selection also includes pump wells with ready-made anchoring - with a concrete slab installed in its structures - get in touch - we will map out a suitable entity for the site. the ground is challengingly soft, will the installation be successful in winter, when the ground can support an excavator? often it is easier to dig in soft ground in winter and move the machine around the installation site, as it is more load-bearing. Winter installation (when there is frost on the ground) may require finishing the ground installation during thawing weather – when the frost has melted. Thermal insulation of the pump well: Thermal insulation is needed when the pumping station may freeze. “Insulation-plate flexible” or, for example, “insulation-plate fixed” can be used in the pump well; our selection includes ready-made insulation packages for the trench, cover and shaft. In addition, an insulation cover (flexible- insulation) is available, which is installed inside the well. The insulation pieces can also be made from general insulation boards used for ground insulation. - get in touch - we will map out a suitable package for the site. Pump well overflow: Pump wells are most commonly equipped with an overflow. Overflow is made with a retrofit seal, the height and direction of which can be freely chosen. The height is to a level where the highest water level adjusted by the overflow does not cause problems for the operation of the sewer. Alarm systems: The level alarm is installed at a level before the overflow. It is possible to use a wireless alarm or connect to the RRC system. The RRC system makes monitoring, management and programming of the equipment easier with remote monitoring. Alarm and reminder information, operating information for larger systems and programming options make it easier to manage and use the equipment. Pump well pipe connections: We use pipe connections made of various sizes (40, 50, 63, 75, 110, 160, 200, 250 mm) made with plastic welding or aretrofit seal. The retrofit seal is installed at the installation site at the selected height and direction. Plastic welded pipe joints are installed in the pump well during manufacturing at the factory. Plastic welded pipe joints are used when the groundwater level can rise above the pipe joint.

Raita pumping station care and maintenance. What needs to be done? Normal operation-related functions, i.e. pumping station inspection once monthly (5-10 min). You can also do periodic maintenance (2-4 hours / every 1-3 years) yourself (if you are technically proficient). Look at technical manual

Acquisition and operating costs. What does acquisition cost - what does operation cost? It is affordable to purchase a Raita pumping station. Its service life is + 50 years. We use the best technology in our products. H2S-off technology and RRC remote monitoring extend the service life and reduce operating and maintenance costs. Look at technical info and certificates.

Environmental friendliness. How environmentally friendly is the Raita pumping station? Long service life (50-100 years) The material is recyclable. The corrosive effect of wastewater can be minimized with H2S-off technology Considering these factors, the carbon footprint of the Raita pumping station is very small.

Odor. Does the use of the Raita pumping station cause odors inside the building or in the yard? NO. A properly designed and built system is completely odorless. For challenging sites, we deliver a pumping station equipped with H2S-off technology , i.e. odor removal. Make an appointment for a remote survey - we will be happy to help you with the design for your site. Kts RaitaPro- sivu. Katso käyttöohjeet teknisillä sivuilla.
