M.E. Simpson Company, Inc. is proud to introduce the comprehensive NASSCO MACP Level 2 Inspection Program, designed to empower utilities with valuable insights into the structural integrity of the sewer structures.

Combined and sanitary sewer overflows are natural hazards for wastewater collection systems. Without a comprehensive solution to monitor troublesome conditions, overflows can be triggered with little warning and lead to expensive and embarrassing situations. Fortunately, versatile analytical systems that capitalize on existing wastewater collection infrastructure hold promise for avoiding such negative impacts.

The Shenzhen Yantian WWTP is located in the Shenzhen Economic Development Zone near the Yantian port in China. The plant is partially surrounded by light industrial businesses and small jewelry factories. It occupies 11.5 hectares (28.4 acres) and serves a municipal population of about 125,000 along with the surrounding industrial amd jewelry businesses

The Mazzei Sidestream Venturi Injection – Pipeline Flash Reactor System provides a feasible alternative for dissolution of ozone at the Clark County Water Reclamation District (CCWRD) in Las Vegas, because it allowed for flexibility in basin design to meet geographic site constraints.

The city of Davisboro is located in Washington County, Georgia. The 2012 census population was 1,793 at the 2013 census. The population includes Washington State Prison, approximately 1,500 prisoners.

Understanding how entrained gas can disrupt flow measurement ― and the technologies that can help overcome this challenge ― are key to ensuring reliable and efficient plant operation.

Measurement is critical to the water industry. Whether it’s improving efficiency levels, investing in infrastructure or funding innovation – one thing is certain, accuracy matters and the sums have to add up.

The City of Scotts Valley sewage treatment plant was having a very tough and frequent problem with their scum pump. This screw pump would rag up monthly, forcing the operators to take it apart and use large wrenches to manually turn the pump to remove the clogged rags and wipes. This was not a sustainable operating model and it was costing the city a lot of time, manpower and money, not to mention causing a lot of frustration.

In May of 2021, the Senate passed the Drinking Water and Wastewater Infrastructure Act of 2021 (DWWI Act). They have allocated $250 million of grant money, broken down into $50 million segments each year starting in 2022 and ending in 2026. Due to this bipartisan legislation, small public water systems should consider taking advantage of this unique funding opportunity. Keep reading to see if you may qualify.

Flow measurement is critical to effective process control and management, whether for municipal or industrial uses. Before you purchase a flow meter, there are a lot of factors to consider. Be sure to answer these questions before deciding on the type of meter to install.

Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.

With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

We arm municipalities with actionable data necessary to make informed decisions about water quality in their communities

Strongly loaded organic industrial waste water, i.e. from sugar- or paper-factories, need to be pre-treated before determining the BOD value.

The Biochemical Oxygen Demand over a testing period of n days (BODn) is precisely defined and associated with experimental standards. It represents the quantity of oxygen aspirated in the course of aerobic breakdown of organic substances by microorganisms.

A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

In wastewater treatment, aerobic digestion enables plants to increase their capacity by injecting oxygen into the wastewater head space.
