crawl Space Drainage and Sump Pump Installation is rarely the whole job. On a Meggett property it sits inside a sequence — the source gets established first, and whatever follows depends on what that inspection finds.
Water keeps coming back, so it needs somewhere to go rather than somewhere to sit.
Drainage and sump pump on lowcountry and coastal plain ground
Near Meggett a sump is often working against a standing water level rather than an occasional event, and close to the coast that level can be tidally influenced. The system has to be sized for water that keeps arriving, and the discharge has to go far enough that it does not simply return.
Coastal Charleston County humidity is the other half of it. For much of the year the outside air here is wetter than the crawl space, so any approach that relies on ventilation to finish the job works against itself.

Why it is worth dealing with now
A crawl space problem in Meggett is not self-limiting. The conditions that created it are still there, and they are still working.

Drainage and sump pump in Meggett: common questions
Can grading fix it without installing a pump?
Sometimes, and it is checked first because exterior water is the cheapest to deal with. Where the water table itself rises into the space, as it can around Meggett, it cannot.
Where does the discharge go on a Meggett property?
Far enough from the foundation that the water does not track straight back in, to a point that is legal locally. Discharging beside the wall is the most common fault we find, and it is why some pumps run constantly.
Why is my Meggett crawl space wet when nothing has leaked?
Near Meggett that is the normal pattern rather than the exception. At around 10 feet on the coastal plain, the water table sits close enough to the surface that soil under the house can be saturated with no pipe broken.
How quickly does water under a Meggett house need to come out?
Quickly. Wood starts absorbing moisture immediately and mold can establish on damp material within roughly 24 to 48 hours. In Charleston County that window is shorter in summer than in winter, because the space stays warm and humid.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Meggett call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
Where should the sump pump discharge to?
Far enough from the foundation that the water does not track straight back in, to an discharge point that is legal where you live. Discharging next to the wall is the most common fault we find, and it is why some systems run continuously.
