What's the difference between a Reinforced and a Prestressed reservoir?
These are a good way to achieve the maintenance free advantage of using concrete for a reduced cost overall. The major difference in this type verse's prestressed is the solid connection of all the components the floor to footing, and the footing to the wall. These reservoirs are all completely locked together. Reinforced is also are capable of being back filled partially or entirely to help minimize its exposure. Thus can be put in neighboring areas where sightlines are a concern. Overall this is a Quality method of getting a maintenance free reservoir for a little less cost.
This model is unique in its seismic capabilities because the design is able to allow movement in the various parts. These free moving areas also are able to allow the reservoir to expand and contract with daily filling/ emptying and temperature changes. The floor and footing are separate from the wall base, and the wall top is separate from the roof structure. They are however each connected with cables that allow movement up to several inches, that can occur when the water is tossed from a seismic event or just the pressure of being full or empty. The base of each connection has hard and soft durometer rubber pads, that support the weight, with a PVC waterstops to keep the water tightness while allowing the movements reservoirs demand. This system is a bit more cost initially, but soon pays for itself with a lifetime of less or no maintenance.
