4 deep well manual pump technical requirements 4.1 installation requirements (1) brackets and legs must be embedded in concrete fixed. (2) A well that is of acceptable quality must be constructed around the hand pump. (3) Drainage facilities must be constructed outside the well platform. (4) Restroom, livestock ring or manure shall not be built within a diameter of 50 m from the hand pump. (5) From the ground to below the permafrost, drill a 1 mm diameter anti-freeze seepage hole in the water pipe. 4.2 Deep well manual pump well (1) Manual pump must be installed in a solid concrete platform. (2) The platform can be built round (diameter 2 m) or square (2 m × 2 m). (3) The platform must have a certain slope and a drainage channel to ensure that the remaining water enters the natural drainage and farmland or seepage pond. (4) The pump outlet is aligned with the centerline of the well. (5) The installed pump should be sealed to prevent stagnant water from flowing into the well. (6) The construction of the well should be firm and crack-free. Pump head should be firm, no shaking. 4.3 Manual pump seepage tank (1) The remaining water in the well is drained through drains. If it is inconvenient to drain into natural drains or farmland, a seepage tank must be constructed. (2) The distance between the seepage basin and the well platform should be not less than 3 m. The seepage basin should be filled with sand, gravel, etc. to infiltrate the ground and prevent ground pollution. (3) If constructing a livestock drinking water pool or laundry pool, not less than 5 m from the pump. 5 Conclusion Deep well hand pumps have been applied and popularized in the suitable areas of 12 provinces since the introduction in the 1980s with the help of the Ministry of Water Resources and the United Nations Children's Fund. 18 602 deep well hand pumps have been installed and beneficiaries have a population of 100 Over 10,000 people are expected to reach 30,000 by 2000. The introduction of deep well hand pump technology has played a positive role in solving the issue of rural drinking water in our country, especially in remote and poverty-stricken areas.
