How to set the quota for rainwater wells and collecting wells, but I can't find the corresponding quota.

1, the rainwater well is a structure, and the quota is set by civil engineering projects, such as digging and filling, cushion, concrete (or masonry) wall, etc.

2. If the UPVC quota of storm sewer cannot find one with a diameter greater than 300mm, set a subtitle with the largest diameter, and then change the material unit price and specifications.

3. There are rainwater pipes for concrete in the municipal quota. Under the chapter of drainage engineering

4. Submersible pumps and water pumps are mechanical installation quotas. Do a good job of inquiring about the equipment cost and auxiliary materials, and the installation cost just reorganized. You can also calculate the weight of equipment according to the mechanical quota, and use "T" to calculate the price.
