About this file
This is a Questions and Answers (Q&A) document from a federal contract solicitation addressing chemical storage container requirements under Contract Line Item Number (CLIN) 0002.
The document clarifies that four chemical storage containers are included under CLIN 0002 at each of two Water Treatment Plants (NAS I WTP and NAS II WTP). Monthly inspection and cleaning requirements apply exclusively to WTP containers; no inspection and cleaning services are required at the Wastewater Treatment Plants (WWTPs). At NAS I, containers include five 1,000-liter tanks storing sodium hypochlorite, caustic soda, citric acid, hydrogen peroxide, and antifoam; two 1,000-liter tanks (total 2,000 liters) for Nutrient B; one 500-liter sodium hypochlorite tank for the WWTP; and one 1,040-liter sodium hypochlorite tank for the Reclaim Water System. NAS II contains identical quantities with slight capacity variations in the Nutrient B tanks (1,600 liters plus 1,000 liters totaling 2,600 liters) and includes an additional 530-liter sodium bisulfite tank for the Reclaim Water System. All containers are constructed of HDPE or polyethylene with specified dimensions ranging from 840 × 1,065 mm to 1,200 × 1,940 mm. The government confirmed that all WTP containers have a maximum volume of 1,000 liters, measure 1.00 × 1.20 × 1.16 meters (IBC type), are constructed of HDPE, operate at typical fill levels of 150 to 200 liters during routine cleaning, and no photographs or drawings are available.

Question 1. How many chemical storage containers are included under CLIN 0002 at each facility, specifically:
• NAS I Water Treatment Plant (WTP);
• NAS II Water Treatment Plant (WTP);
• NAS I Wastewater Treatment Plant (WWTP);
• NAS II Wastewater Treatment Plant (WWTP).
Answer:
NAS I Water Treatment Plant (WTP); Four.
NAS II Water Treatment Plant (WTP); Four.
NAS 1
Products: sodium hypochlorite, caustic soda, citric acid, hydrogen peroxide, antifoam Quantity: 5 tanks Nominal capacity: 1,000 L each Approximate dimensions (diameter × height): 1,100 × 1,200 mm Material: HDPE Typical operating fill level during routine cleaning: NA
Product: Nutrient B Quantity: 2 tanks Nominal capacity: 1,000 L each (total 2,000 L) Approximate dimensions: 1,200 mm (L) × 1,000 mm (W) × 1,160 mm (H, including pallet) Material: HDPE Typical operating fill level during routine cleaning: NA
Product: Sodium hypochlorite (WWTP) Quantity: 1 tank Nominal capacity: 500 L Approximate dimensions (diameter × height): 1,340 × 820 mm Material: Polyethylene Typical operating fill level during routine cleaning: NA
Product: Sodium hypochlorite (Reclaim Water System) Quantity: 1 tank Nominal capacity: 1,040 L Approximate dimensions (diameter × height): 1000 × 1460 mm
Material: Polyethylene Typical operating fill level during routine cleaning: NA
NAS 2
Products: sodium hypochlorite, caustic soda, citric acid, hydrogen peroxide, antifoam Quantity: 5 tanks Nominal capacity: 1,000 L each Approximate dimensions (diameter × height): 1,100 × 1,200 mm Material: HDPE Typical operating fill level during routine cleaning: NA
Product: Nutrient B Quantity: 2 tanks Nominal capacity: 1 × 1,600 L + 1 × 1,000 L (total 2,600 L) Approximate dimensions of the 1,600 L tank (diameter × height): 1,100 × 1,940 mm Approximate dimensions of the 1,000 L tank (diameter × height): 1,200 mm (L) × 1,000 mm (W) × 1,160 mm (H, including pallet) Material: HDPE Typical operating fill level during routine cleaning: NA
Product: Sodium hypochlorite (WWTP) Quantity: 1 tank Nominal capacity: 500 L Approximate dimensions (diameter × height): 1,340 × 820 mm Material: Polyethylene Typical operating fill level during routine cleaning: NA
Product: Sodium hypochlorite (Reclaim Water System) Quantity: 1 tank Nominal capacity: 1,040 L Approximate dimensions (diameter × height): 840 × 1,065 mm Material: Polyethylene Typical operating fill level during routine cleaning: NA
Sodium bisulfite (Reclaim Water System) Quantity: 1 tank Nominal capacity: 530 L
Approximate dimensions (diameter × height): 840 × 1,065 mm Material: Polyethylene Typical operating fill level during routine cleaning: NA
2. Are all of these containers subject to the monthly inspection and cleaning requirements, or do the monthly cleaning requirements apply only to the WTP containers described in the Statement of Work?
Answer: WTPs containers only. No inspection and cleaning to be performed at the WWTPs
3. For each chemical storage container included under CLIN 0002, could the Government also provide, if available:
• storage capacity (liters or gallons);
• approximate dimensions;
• construction material (e.g., HDPE, FRP, steel);
• typical operating fill level during routine cleaning;
• any available drawings or photographs.
Answer: storage capacity (liters or gallons); All containers at the WTPs have a maximum volume of 1,000 liters. Approximate dimensions; All containers at the WTPs are IBC type with the following size: length 1,00 mt, width 1,20 mt, height 1,16 mt. Construction material (e.g., HDPE, FRP, steel); HDPE typical operating fill level during routine cleaning; from 150 to 200 liters any available drawings or photographs. No pictures available.
