They are also designed where sewerage from development areas or new collection networks when is not able to be drained by gravity to existing sewerage infrastructure, or where development areas are too far from available sewerage infrastructure to be connected by gravity conduits.<\/p>\n<p>Therefore, in the case of pumping sewer from a deep manhole to a shallow adjacent manhole, it is called lift station. In the other cases, to convey sewer to a far distance facility, it is categorized as pumping station. Although the technical criteria are similar, generally pumping stations required significant considerations such as the design and operation of force mains.<\/p>\n<p>\n<\/div><\/div><\/div><\/div><\/div><\/div><div class=\"kc-elm kc-css-539694 kc_col-sm-6 kc-animated kc-animate-eff-fadeInUp kc_column kc_col-sm-6\"><div class=\"kc-col-container\"><div class=\"kc-elm kc-css-355456 kc_row kc_row_inner\"><div class=\"kc-elm kc-css-599015 kc_col-sm-12 kc_column_inner kc_col-sm-12\"><div class=\"kc_wrapper kc-col-inner-container\"><div class=\"kc-elm kc-css-210623 kc_shortcode kc_single_image\">\n\n        <img src=\"http:\/\/www.pod-eng.com\/wp-content\/uploads\/2023\/05\/p76.png\" class=\"\" alt=\"\" \/>    <\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section><section data-kc-equalheight=\"true\" data-kc-equalheight-align=\"top\" class=\"kc-elm kc-css-27720 kc_row\"><div class=\"kc-row-container  kc-container\"><div class=\"kc-wrap-columns\"><div class=\"kc-elm kc-css-54668 kc_col-sm-6 kc-animated kc-animate-eff-fadeInUp kc_column kc_col-sm-6\"><div class=\"kc-col-container\"><div class=\"kc-elm kc-css-488159 kc_row kc_row_inner\"><div class=\"kc-elm kc-css-155662 kc_col-sm-12 kc_column_inner kc_col-sm-12\"><div class=\"kc_wrapper kc-col-inner-container\"><div class=\"kc-elm kc-css-840242 kc_text_block\"><\/p>\n<h2><strong>Preliminary Study<\/strong><\/h2>\n<p>Design Flow, Min. &#038; Max. sewer flow, Run-off estimation, etc.<\/p>\n<p>Location and Configuration; Local topography, Size and type of the pumping station, Access considerations for O&#038;M needs including operators\u2019 health and safety issues, Visual impact, particularly the vent tube, odors, noise problems, etc., Vulnerability of the site to a natural and man-made disaster.<\/p>\n<p>Design of levels; Suction level, discharge level and top or bottom alarm levels<\/p>\n<h2><strong>Design of equipment<\/strong><\/h2>\n<p>Designing the equipment installed in the sewerage pumping station including; gates, screens, grit removal systems, conveyors, odor removal system and piping.<\/p>\n<h2><strong>Design of Pump<\/strong><\/h2>\n<p>Types of pumps, types of Pumping station &#038; number of Pumps; Due to the operation and maintenance costs, these parameters are considered one essential factor to design sewerage pumping stations.

Therefore, the constructional cost is increased dramatically. Although it seems the operation of one pump is more simpler, the total cost in the lifetime, the maintenance costs, energy cost, etc. would not be less than other options.<\/p>\n<p>Designing pump stations with multiple parallel pumps are more economic and practical in many aspects. For example, in case of minimum or average daily dry flow conditions, just one pump could be operated. In maximum flow, two pumps are in the service and in wet weather flow, three or more pumps may be considered to convey the flow. Therefore, due to less volume for suction chamber, the construction costs will be decreased and it provides a flexible situation for operation. On the other hand, increasing the number of pumps could be complicated for the operators and the more pumps, the more costs of operation and maintenance. Therefore, there is a technical challenge to balance the construction costs, operation and maintenance costs which could be overcome by an engineering concept. To conclude, the number of pumps is the main factor and it needs optimal design to consider all the aspects.<\/p>\n<p>On the other hand, designing pump stations with multiple parallel pumps is more economical and practical in many aspects.
