Waste Water

Suppliers to the waste water market

Waste water is a widespread term which refers to the removal, transportation and treatment of waste water that can be either municipal/domestic, industrial or environmental. For many years Castle Pumps have been supplying waste water pumps that are required for a vast range of different waste water applications.

Municipal/domestic waste water, including toilet waste and dirty water from sinks, showers and washing machines, is transported via a sanitary or combined sewer system to a waste water treatment plant. When this waste needs to be moved uphill or over long distances, pumps are required to push it through the sewer and drainage system rather than relying on gravity. Castle Pumps offer these solutions. Waste water may also be environmental, which refers to rain/storm water, river water and sea water that needs to be pumped away or transported elsewhere. 

Waste water from industries including manufacturing, steel, paper, textile and food processing is often corrosive and abrasive as it may have contaminants such as swarf, lime, diluted paint, oil and acid. Industrial waste water pumps need to be constructed of wear-resistant materials including cast iron and stainless steel to deal with this nature of liquid. Over the years, Castle Pumps have gained the experience to determine what type of waste water pump is suitable given the type of contaminants present.

Our waste water pump range

Our waste water pump range extends to all waste water applications; whether this be for transporting sewage water to a treatment centre or pumping away rain water from a flooded area. Castle Pumps’ specialist knowledge means that they know what pump to specify for what waste water application. For example, those handling sewage water need to be able to cope with solids, which is why peristaltic pumps and progressive cavity pumps are popular choices. Submersible and centrifugal water pumps are common for standard waste water applications due to their high flow rates and impeller types that enable particle transfer. 

• Sewage pumps – For transferring sewage from homes and businesses to a treatment centre.
• Dewatering pumps – For draining away excess ground water on construction sites, fields etc.
• Grey water pumps – For the transfer of dirty water from kitchen and washing facilities, usually with the aim of recycling.
• Flood pumps – For pumping out floor water from someone’s basement.
