E/One pump stations reduce sewage, expenses for Ontario home developer

John Brooks Company helped a home developer with new sewage pumps.

John Brooks Company Limited backs up its credibility with a long history of customer success stories, including one involving a home builder and developer that needed a low-flow alternative to gravity sewers in Trenton, Ont. Since the municipality could not increase the wastewater-treatment sewer capacity, the company was struggling with some neighbourhood developments. To solve the limitation challenges of the sewer system, John Brooks Company recommended a system of E/One indoor grinder pump stations.

Removal of infiltration, intrusion water

The builder contacted the supplier’s application specialists, who worked with E/One to create a low-pressure sewer design for the development. After finishing the design, the specialists met with the municipality to present the solution and offer several E/One installation references to show how the project could succeed. As part of a low-pressure sewer-system solution, the E/One IH901 indoor grinder pump was suggested for removing infiltration and intrusion water from the sewers, which would reduce sewage produced by half.

The municipality approved a test installation of the proposed system, on the condition that the John Brooks Company team would install a metering chamber at the end of the development’s street, where officials could monitor and confirm the numbers.

Each of these pump stations had a capacity of 344.47 litres, a flow of 26½ to 56.78 litres per minute, a pressure of 80 pounds per square inch, an inlet velocity of 1.09 metres per second, a motor that ran at 1,725 revolutions per minute, and an energy efficiency from six to 23 kilowatt hours per month. The IH901 series also has stainless steel unilateral valves that prevent back flow, corrosion-resistant HDPE tanks, and adaptable 1¼-inch discharge connection.

Following the test, the municipality confirmed a 50 per cent reduction in produced sewage and gave the go-ahead for permanent installation. Another result was higher efficiency, since the system pumped only the household sewage, rather than the ground and surface water in conventional sewers. The customer now saves between $30,000 and $35,000 a year.
