Portable Toilets for Construction Projects in Nanjing

When selecting portable toilets for construction projects in Nanjing, it is essential to consider core needs, key product features, and local service resources comprehensively.

I. Clarify Core Needs

1. User Numbers and Locations: Determine the procurement quantity and capacity of individual toilets based on the number of workers, planned toilet locations, and the capacity of each location. For example, high-density construction areas may require additional locations or larger-capacity toilets.
2. Usage Duration: For short-term projects (e.g., within 3 months), leasing may be considered, while for long-term projects (e.g., over 1 year), purchasing is recommended, with priority given to durable materials (e.g., metal carved panels).
3. Site Conditions: If the ground is uneven, choose toilets with self-leveling functions; for sites without water and electricity connections, opt for packaged or biodegradable toilets to avoid reliance on external resources.
4. Waste Removal Conditions: For construction sites with narrow surrounding roads or difficult vehicle access, choose toilets with large septic tank capacities and long waste removal cycles to reduce maintenance costs.

II. Focus on Key Product Features

1. Cabinet Structure and Materials: Prioritize high-strength FRP composite materials (fiberglass) or metal carved panels, with a plate thickness of ≥5mm and a frame made of galvanized steel pipes to ensure overall stability. Hardware components (e.g., door locks, hinges) should be rust-resistant, and handrails should conform to ergonomic design.
2. Treatment Methods and Environmental Friendliness:
   • Flush-and-discharge type: Suitable for long-term projects with fixed sewage pipes and sufficient water and electricity, but requires regular septic tank cleaning.
   • Recirculating flush type: Treats wastewater through biodegradation technology, achieving a water-saving rate of over 80%, suitable for construction sites with water shortages.
   • Packaged/biodegradable type: Requires no water or electricity, with feces packaged in biodegradable film, suitable for short-term projects without infrastructure, but requires regular replacement of consumables.
   • Vacuum suction type: Uses negative pressure to quickly remove waste, with less odor and water conservation, but higher equipment costs, suitable for high-end projects or areas with strict environmental requirements.

III. Utilize Local Service Resources
There are several professional service providers in Nanjing, such as Nanjing Yunshui Environmental Protection Service Co., Ltd., which offers one-stop services including leasing, transportation, installation, and cleaning. Their products cover various types such as flush and environmentally friendly toilets, meeting different budget requirements. Additionally, the Nanjing Urban Management Bureau once procured vehicle-mounted portable public toilets with a budget of 1.17 million yuan, indicating the government's emphasis on portable toilets. Project parties can refer to such standards when selecting compliant products.

By scientifically planning needs, strictly screening products, and reasonably utilizing local resources, the usage efficiency and management level of portable toilets in construction projects in Nanjing can be effectively improved.
