<br />As noted in Section 2.5 on page 7, if the sump pump does not operate, this system can be a <br />conduit directing water into the basement. On the other hand, a properly installed system can <br />protect basements during surface flooding. As long as there is a barrier that keeps surface <br />water from reaching the building, a drain tile and sump pump should keep the underseepage <br />from building up water pressure on the basement walls and floor. <br /> <br />Installing or correcting these drain tile systems and sump pumps is considered flood proofing <br />in many communities. Correction projects include larger or additional sump pumps, backup <br />sources of electricity for the pumps during power outages, and redirecting the outfall. <br /> <br />Cost: $50 - $15,000. Lower cost projects include adding a second sump pump or power <br />backup source. The most expensive approach would entail retrofitting a house with a drain <br />tile and sump pump and waterproofing basement walls. <br /> <br />2.6 For More Information <br /> <br />Several good references on flood proofing techniques are available from the U.S. Army Corps <br />of Engineers.
