Benefits of Packaged pump station sewer services

Posted by Austere Pumps on April 24th, 2019

Having efficient Packaged pump station sewer services is a benefit that translates into the health and well-being of citizens. It has many benefits, as in case of heavy rainfall, to prevent the flood from reaching the inhabited areas.

Packaged pump station is responsible for the disappearance of sewage, the waste caused by the activity of the population. It's treatment must be adequately maintained as the population grows and thus also the waste increases considerably.

The vacuum well

 Wastewater generated by 4 or 6 homes arrives by gravity to the vacuum well. When the level of the water rises, the air is compressed inside the tube-sensor by pressing the regulator to open the vacuum valve. When the valve opens, it draws the volume of water into the network of pipes in depression. The pressure difference pushes the water through the network towards the vacuum station. It should be noted that the mixture of wastewater and air can reach a speed between 4 and 6 m / sec.

 The vacuum network

 The network can be installed in narrow and shallow ditches. The sawtooth profile of the network is consistent with the natural slope of the terrain and helps the maximum depth of the facilities to remain very shallow, between 1 and 1.5 m generally. This is why it is more efficient than conventional Sewer Pump station in terrain with a favorable slope to water flow, in flat terrain (without slope) or in terrain in contrapendiente and unfavorable to the flow of water.

 The minimum slope of the vacuum pipe is 0.2% in the direction of the vacuum station, although it may be higher. The lifts or ascents are manufactured by prefabricated pipe or with two 45 degree elbows.

 In comparison, the conventional gravity sanitation network requires, in the same situation, more slope and larger diameters. The two-phase vacuum system achieves high speeds, which is why it is considered a self-cleaning system and, in comparison, much more efficient.

 Generally, the vacuum network is designed radically to the Fibre Pump stations (the station where the vacuum is generated and wastewater collected), being able to reach large distances in total, up to 5 km on flat terrain, always under the limitation of losses of the system. As it is a very flexible system, it also admits more provisions of the vacuum network, for example in the form of a comb or fishbone.

 The vacuum station

 The vacuum station is the center where the lines of the vacuum network end. Each line is connected to the vacuum reservoir as far as the wastewater and the air that has been sucked into the vacuum wells. Inside the vacuum tank, the water that accumulates in the bottom is pumped by means of standard impulse pumps to the sewage treatment plant (WWTP) or to the connection point of the existing conventional sewage system.

Therefore, when there are no favorable conditions for the installation of sewerage by gravity, the vacuum sewer system is an alternative and viable solution that would reduce costs and in general the investment to be made.
