Sewer Cleanouts

“How can plumbers clean and inspect the pipe connecting homes to municipal sewers?”

               Lateral sewer lines connecting homes to municipal sewers become clogged from time to time. If this is not addressed, the clogging can develop into blockages and long-term damage to the piping infrastructure. So how can we use our engineering mindset to quickly clean the home piping without ripping out the existing piping and landscaping systems? Well, what if we were to install a vertical pipe on top of the lateral sewer line with an unlockable surface opening? These services, called Sewer Cleanouts, allow licensed plumbers to inspect and clean home pipes. Sewer cleanouts often appear as white capped pipes sticking up from the ground.

Lateral Sewer Lines

“What pipe connects houses to the municipal sewer system?”

                Connecting a building to a municipal sewer system is one of the most common ways to implement high-quality sanitary access. Lateral Sewer Lines, or sewer pipes that extend from a building’s waste system to a municipal sewer main, are an excellent way to accomplish a home-to-sewer connection. Lateral sewer lines are typically located on private property, requiring the owners to assume responsibility for theirmaintenance. Laterals are tyoically sloped downwards to transport waste through gravity, and can become clogged by tree roots, grease, and other factors.

Solids Residence Time (SRT)

“How can we measure how long on average microorganisms spend in a wastewater reactor?”

Microorganisms are the backbone of wastewater reactors. These microscopic solids work hard to clean incoming wastewater to suitable environmental levels. But these pieces of biomass only have a limited amount of time in the reactor as solids are ejected from the treatment system. The average amount of time a microorganism spends in the reactor, known as the Solids Residence Time, is equal to the total biomass within the system divided by the exit flow rate of biomass. We can represent this relationship with the formula SRT = Total Volume of Biomass/(Waste rate of biomass + Effluent rate of biomass). A low SRT indicates a reactor is quickly cycling through biomass, which leads to a mostly young bacteria, while a high SRT has the opposite properties. 

Why You Should Consider Disconnecting Your Downspout From the Sewer System

“Why should you consider disconnecting your downspout from the sewer system?”

Downspouts carry water from rooftop gutters to the ground. Many homes have their downspouts connected to the sewer system by default. In combined sanitary sewer areas, this means that rain that falls on rooftops will enter the same pipes that carry sanitary waste. During rainstorms, the amount of water entering sewer lines from downspouts may be so large that it overwhelms the system, resulting in a combined sewer overflow event. If you own a building, you can reduce the chance of CSO occurrence by disconnecting your downspout and directing it to infiltrative material. Not only will the sewers get less overwhelmed, but this opens the opportunity to provide much-needed water to your own vegetation. This is Why You Should Consider Disconnecting Your Downspout From the Sewer System.

“How can we use pipes to channel water away from the roof gutters of buildings?”

Water piles up on roofs during rain events. Gutters are installed on roofs to channel water away. To avoid buildup in the gutters, people can install Downspouts, pipes connected to gutters to allow water to move away into safer areas such as sewers or a retention basin. Downspouts are a simple yet effective method to prevent building damage.
