Solutions for High Water Tables Waterproof Your Basement: In addition to sealing cracks in your basement walls, installing basement waterproofing solutions, such as an interior drainage system and a sump pump, will help prevent flooding.
Generally speaking the way to lower a water table is to pump the water out and then deal with it somehow (ie pump it into a river, lake, etc). The amount of water you would need to pump out would be substantial and you would probably need multiple pumps working non-stop to get the water table down.

Humidity Issues: A high water table can increase moisture levels in the basement or crawl space, creating ideal conditions for mold growth, wood rot, and rust on metal components. Over time, this excess moisture compromises the structural integrity of your basemen or crawl space and home.
High groundwater doesn't necessarily preclude the area from being suitable to build, you'll just have specific considerations to keep in mind. For example, in my part of Washington state, the only way to have a basement realistically is to build it into a slope and have it be a walkout.
A high water table can cause big problems for your home. When the water table rises, it pushes against your foundation. This can lead to leaks, cracks, and even cause parts of your house to settle unevenly if the pressure gets too high. Over time, this can cause serious damage that is expensive to fix.
Installing French drains, moisture barriers, and even altering your landscape to divert water are all effective high water table solutions. Consult the Experts: Draincom specializes in identifying and solving the challenges of waterproofing your basement, including water table issues.
According to data from more than 1,200 San Joaquin Valley monitoring wells, the water table has been dropping for at least two decades, in many places more than 2.5 feet per year on average.
You may ask how you can you tell if you live in a high water table or just have poor drainage? A telltale sign of a high water table is if your neighbors experience similar flooding issues or if your home is near a water source such as a lake, river, or marsh.
The drying effect of fly ash in wet soil occurs rapidly, allowing you to quickly proceed with construction activities. Fly ash also makes soil more resistant to water infiltration." All you have to do is till up the wet soil and mix in the fly ash to physically soak up the water.
Foundations, walls, and floors may suffer structural damage due to the saturated soil. Settlement issues, uneven settling, and compromised stability can occur on buildings situated on a high water table. Reduced thermal efficiency: dampness in the wall fabric reduces the thermal efficiency of the building.
Diminishing the flow of a river, the construction of massive dams and reservoirs, decreasing frequency of flood events, and pumping groundwater along its course, will lead to water table declines for hundreds of kilometers downstream with severe impact on the ecology of riparian zones (e.g., Sophocleous 2010; Zheng et ...
In some cases a French drain will mitigate the problem and sometimes you have to have a sump pump incorporated to keep a high volume of water diverted.
Open drainage (dewatering with pumping from wells, slits or drainage sumps) is the simplest method. The groundwater flowing into the excavation pit is collected and pumped away together with any rainwater that may occur.
The most severe consequence of excessive groundwater pumping is that the water table, below which the ground is saturated with water, can be lowered.
During heavy rainfall, the water table tends to rise because of increased infiltration and recharge from the rainfall. The excess water from the rainfall fills up the spaces in the soil and raises the water table level. This can lead to localized flooding and an increase in shallow groundwater.
If a high water table is present, the use of Continuous Flight Auger (CFA) or driven piles are recommended, as both of these piling techniques are an effective solution for building on sites with high water tables.
During the late winter and spring when accumulated snow starts to melt and spring rainfall is plentiful, water on the surface infiltrates into the ground and the water table rises.
The water table drop caused by the presence of vegetation is generally attributed to lower recharge rates due to rainfall interception and plant transpiration [e.g., Wilde et al., 1953; Borg et al., 1988; Riekerk, 1989; Dubé et al., 1995], and to uptake by “taproots” extracting water directly from the (unconfined) ...
Local authorities are responsible for managing the risk of flooding from groundwater.
If water is withdrawn from the ground at a faster rate that it is replenished, either by infiltration from the surface or from streams, then the water table can become lower, resulting in a "cone of depression" around the well.
A high water table occurs when the groundwater is close to the surface, sometimes just above the crawl space or basement floor. This usually happens after heavy rain or when water from higher elevations (like on a hill or mountain) drains into the soil around your home.
One way to ensure that water drains away from your home is by landscaping in a strategic manner. By utilizing rocks for drainage, you can keep water away from your foundation and your home.
During periods of low rainfall, for example, a water table will fall. On the other hand, during periods of abundant rainfall recharge, water tables will rise (Figure 8 and Figure 9).
