Roth MultiTank® — 1500 Gallon Underground Cistern
The Roth MultiTank® is the first tank of its kind — equally suited as a water cistern, rainwater collection tank, pump tank, holding tank, or septic tank. Its patented COEX-4 multi-layer co-extrusion process combines an inner layer of FDA-approved virgin HDPE, two interior PE layers for structural stability, and an outer layer of black UV-stabilized PE. It carries the best warranty in the industry: lifetime corrosion protection and 5-year labor insurance coverage.
When used as a potable water or rainwater cistern, it stores water collected from a roof or other catchment area — ideal for rural homes and farms as a supplement or primary water source during dry periods. Two-compartment configurations are available; contact us for details.
Dimensions and Capacity
Tank capacity depends on configuration:
-
1,771 gallons — filled from a water truck with no inlet/overflow holes drilled
-
1,540 gallons — with inlet and overflow holes drilled (standard rainwater harvesting setup)
Note: This Roth tank is physically larger than the Norwesco 1725-gal tank. Norwesco measures capacity without inlet/overflow holes; Roth measures with them — which explains the apparent size difference.
Tank dimensions: 51"H × 62"W × 177"L
