Solution for Rural Direct Drinking Water Projects

2024-05-31

Most of the tap water in rural areas of our country is well water, with calcium content and aluminum ion exceeding standards. After long-term consumption, many residents have suffered from regional diseases such as kidney stones and urinary tract stones. Nowadays, rural areas also face severe water pollution due to the use of chemical fertilizers. Therefore, the renovation project of rural tap water will be the most urgent issue to be addressed in rural areas in the future. The quality-based water supply provided by our company can meet the national standard for drinking water, can be consumed directly, and has low costs.

Solution for Rural Direct Drinking Water Projects



Introduction to Rural Quality-Based Water Supply Domestic Water, Drinking Water for New Countryside

Quality-based water supply is a new drinking water method in China, which refers to separating domestic drinking water (for drinking, cooking soup, cooking, etc.) from domestic sanitary water (for bathing, flushing toilets, washing clothes, etc.), and supplying them through different pipelines respectively. Among them, domestic sanitary water uses ordinary tap water, while drinking water is high-quality domestic water processed by deep purification from ordinary tap water as the water source. It features the removal of harmful substances in water such as water pollutants, disinfection by-products, and secondary pollutants in water pipelines, and can be directly drunk without boiling. Therefore, it is also known as pipeline direct drinking water, with clean water quality, oxygen-rich, and vitality more beneficial to human health.


Application Scope of Quality-Based Water Supply System:
Residential communities, office buildings, hotels, restaurants, schools, factories, etc.

Advantages of Rural Quality-Based Water Supply System:

(1) High-Quality Water: The effluent water quality meets the standard for drinking purified water and can be directly consumed.
(2) Prevention of Secondary Water Pollution: The entire system is closed and self-priming, with regular cyclic sterilization, ensuring no turbid water in the pipelines and preventing secondary pollution during water supply.
(3) Convenience and High Cost-Effectiveness: The pipeline direct drinking water system is easy to use and cost-effective, solving the problems of high price and difficult transportation of bottled water.

Compilation Outline of This Implementation Plan
This outline applies to decentralized projects such as joint villages, single villages, or other rainwater harvesting projects with a water supply scale of less than 1,000 cubic meters per day. Among them, centralized water supply projects with unified water sources in joint villages and single villages shall be designed with reference to the Preliminary Design Outline for New Rural Drinking Water Safety Projects in Henan Province. For each project, the water supply population, types of water quality exceeding standards (inadequate water quantity), selection of water sources, project scale, project form, detailed investment estimation, etc., shall be explained chapter by chapter and location by location. Projects with the same form can adopt typical designs by category, and different ones shall be surveyed and designed one by one. Decentralized projects such as water cellars for households or two 联户 (joint households) in a village can adopt typical designs by category, and summarize and explain the water supply population, types of water quality exceeding standards (inadequate water quantity), selection of water sources, project scale, project form, detailed investment estimation, etc., by village as a unit.

The implementation plan shall be text-standardized, concise, with prominent key points, and complete with diagrams and tables. Taking counties as units, list and summarize the townships (towns, offices), place names, quantities, types of water quality exceeding standards, total investment estimation, etc., for each project's water supply.

Preface

  • Approval of the Feasibility Study Report for New Rural Drinking Water Safety Projects;

  • Management Measures for Rural Drinking Water Safety Projects;

  • Relevant technical standards such as Technical Standards for Urban and Rural Water Supply Projects;

  • Other relevant regulatory bases.


1.2 Guiding Principles for Compiling the Implementation Plan
Put forward specific guiding principles around the goal of building a new socialist countryside.

1.3 Standards for Compiling the Implementation Plan
Priority to urgency and severity, centralized and contiguous implementation, appropriate scale, adaptation to local conditions, sustainable use of water sources, etc.

Scope of Solution:
(1) Excessive fluoride in drinking water; excessive arsenic in drinking water.
(2) Iron and manganese or other water quality problems caused by natural factors.
(3) Drinking water problems with severe water source pollution that have threatened farmers' health.
(4) Issues in some areas such as insufficient water quantity, low guarantee rate, and inconvenient water collection.

For the defined scope of solution, attach the current water quality test results provided by qualified testing institutions. The solutions shall be consistent with the water quality exceeding factors.

1.4 Construction Tasks
This plan intends to solve the total number of people, classify and count the names and quantities of townships and villages by unsafe factors, key construction contents, etc.

  1. Overview of Regional Construction
    2.1 Socioeconomic Situation
    2.2 Geographical Environment and Geological Conditions
    2.3 Current Status of Unsafe Rural Drinking Water
    Causes, hazards, and distribution of unsafe rural drinking water, achievements made in previous work on rural drinking water safety, and the current number, types, and distribution of drinking water safety issues to be solved, clarifying the current tasks.
