sumps

The results showed that building sumps in field combined with covering catchment film between ridges was an effective method , which featured big catchment amount , low cost and easy to build and popularize .

结果表明，在田间建集水坑，在垄间覆膜作集水面是一种有效的集水方法，集水量大，建造简单，成本低，易于推广。

Radon gas enters houses through openings such as cracks at concrete floor-wall junctions , gaps in the floor , small pores in hollow-block walls , and also sumps and drains .
