Some system owners prefer to have plastic or high-density polyethylene (HDPE) septic tanks installed. They’re resistant to cracking and they don’t rust. Typically, they are more affordable up front, and their lighter weight makes them easier to transport and install.
Researchers and environmental experts suggest septic tank users seek out and use environmentally friendly cleaners. Baking soda, borax, oxidized bleaches and vinegar can be effective cleaning agents. Plus, they’re less damaging to and help extend the life of your septic tank and drainfield system.
Did you know that, at a construction site, drainage and overall water movement is determined by soil composition? This is why excavation contractors will test the soil to see if the dirt is clay, sandy, rocky, or a mixture.
The drainfield of a septic system is carefully planned and tested to make sure that the ground is absorbent enough, a process called a "perc" test. Once the drainfield is set up, it's connected to the septic tank. A well constructed drainfield will safely dispose of your waste water without you even noticing.
When an excavation project needs to be done underwater, a normal backhoe simply can’t get the job done. In cases like this, excavation experts will use a dredger, which is made to be able to dig underwater, such as in harbors or waterways.
What size septic tank do you need? This varies widely, but at minimum septic system installation experts recommend a 1000-gallon tank for a two-bedroom house. The typical three- or four-bedroom home generally requires a 1500-gallon tank or larger, based on use patterns and household size.
