Water Pump Removal
With a motorized or hand water pump, water can easily be pumped out of the ditch and disposed of in a secure holding tank, like a 5-gallon trash can or a large water barrel. These pumps vary based on cost.
The manually operated pumps are much cheaper than the motorized water pumps, which run on gas power. A siphon can even be made out of a hose by simply sucking water up, above the water level of the ditch and letting it drain into the trash can or water barrel.
Do not swallow any of the water and spit it out immediately if you must use this method to drain the ditch. A hand pump can be used to start the siphon of the water through the hose also, so none of the ditch water needs to get near your mouth Once the ditch has been drained, the water should be taken to a water treatment plant or dumped in a place where it does not effect the natural environment and can evaporate over time, like the city sewer.
Shop vacuums are heavy duty vacuum pumps that can extract anything, including excess water. The water is simply deposited in a large plastic trough within the vacuum.
Once the shop vacuum container has been filled, it can be dumped into a holding tank of some kind. The only difficult thing about using the shop vacuum is that it needs an electrical source to operate, so you will have to run an extension cord off some power source, like a car battery.
Just use caution so that you do not short out the shop vacuum connection in the ditch water.
Much like you would do with a private septic tank system, a company can be called to drain the ditch. These companies work directly for water and sewage treatment plants by sucking up the water or waste and storing it in a massive tank on the back of their truck.
If you already use a sewage removal service for your septic tank, see if they will also remove the water from the ditch. This may prove to be expensive, depending on how big the ditch is and how difficult it is for the sewage treatment professional to get to the water.
However, once they suck it up, it will be disposed of properly and safely at a professional water treatment plant.
