Conduct an on-site settlement audit, as shown, for the field survey data and the contractor's application data, there are several points of concern:

Such a shoddy water meter well clearly couldn't have been constructed for over a thousand yuan. How should the cost be determined?

2. The water meter well only contains a water meter and a stop valve; how are their specifications determined? Are they the DN25 specifications measured?

3. Is the water meter installation fee reasonable?

Water meter manholes, water meters, and valve specifications, as shown in the diagram, are based on site survey data and construction party reported data.

1. Such shoddy water meter wells clearly wouldn't cost over a thousand yuan to make; the cost should be calculated by applying the relevant定额子目 items item by item according to actual practices.

2. The well only contains a water meter and a stop valve; their specifications are determined according to the design drawings and are measured at DN25.

The water meter installation fee is reasonable and determined in accordance with the local water utility company's regulations.
