Characteristics

Rainwater Cisterns

The Roth MultiTank is the first tank of its kind. It can be used for water cistern, pump, holding, rainwater or septic tank. This is possible due to its special construction of an inner layer of FDA approved virgin HDPE, two inside layers of PE for improved stability, plus one outer layer of black and UV-stabilized PE.

Not only is it special in terms of its construction, it also has the best warranty the industry has to offer: lifetime corrosion protection and 5 years of labor insurance coverage (see warranty for more details).

When used as a Potable Water Cistern, also known as a Rainwater Cistern tank, it is used for storing rain water collected from a roof or other catchment area. Cisterns are sometimes used for storing hauled water, but are usually used as a supplement to other water sources. Cisterns are very useful when the regular source of water for a farm or rural home becomes low in dry periods of the year.

Accessories

	Volume Filter (RRW-VF150) — for systems up to 4500 SF Rainwater filter for small to mid-size systems where underground installation is desired. Unique dual cascade filtration provides a high level of filtering efficiency, independent of flow rate, for roof areas to 4500 sf. Self cleaning, low maintenance filter provides continuous filtering of dirt particles to .55mm. Extension tube is adjustable from 250mm to 750mm and includes a lid that will support pedestrian loading. Filter housing is frost resistant and made out of high quality, recyclable, PE plastic, with the secondary mesh made from stainless steel.
	Standard Overflow Siphon (RRW-OVRFLW) Once a maximum level is reached in the tank, the innovative overflow siphon, with its skimmer effect, removes particles lighter than water (e.g. flower pollen, oils, etc.) that float slowly to the water surface. Removing this floating layer of surface pollutants through regular overflow from the tank is important in order to maintain high quality water and allowance of oxygen diffusion at the water surface. The narrow slits in the overflow siphon prevent rodents from entering the tank.
	Floating Intake with hose (RRW-FSCF) An air-filled ball suspends the floating inlet filter just below the water surface where the cleanest water resides. A high quality 1" dia flexible hose allows for connection of the floating inlet to a pump or suction line. Filter is made out of lead-free brass with a 1.2 mm stainless steel screen and a built in check valve.
	Filter Collector (RRW-FILCA) — for a system up to 750 SF Leaves and debris that cause sludge build up and poor water quality are removed through a stainless steel mesh, allowing the cleaned water to enter the storage tank. Easy to install into existing rectangle or round downspouts. Provides side discharge of filtered rainwater. Dirt and debris continue through the downspout. Made from tough, durable, and recyclable PE plastic. Easy to maintain with removable filter cartridge.
	Compact Filter (RRW-COMFLT) — for a system up to 2100 SF Incoming water is continuously filtered through a two stage cleaning system. The first stage removes larger debris such as leaves and other organic matter, which protects the finer second stage from cloging. After the finer particles are removed in the second stage the clean water flows into the storage tank through the calmed inlet. A small amount of water carries the dirt into the overflow of the tank. Two stage filter is easily removed for cleaning. Filter housing is made of high quality, recyclable, PE plastic, with the two stage filter material made from stainless steel. Install inside a RMT 12" riser.
	Calmed Inlet (RRW-CI) Water leaving the filter enters the storage tank through the 'calmed inlet'. The inlet prevents the disturbance and re-suspension of fine sediments that gather on the bot-tom of the tank. Another important function of the inlet is the introduction of oxygen into the lower layers of the tank which maintains a fresh supply of water while preventing anaerobic conditions from forming.
