How thick should a concrete slab be for a water tank?
How thick should a concrete slab be for a water tank?
100mm thick
Rainwater Tank Installation on CONCRETE SLAB Concrete Slabs for rainwater tank installation must be a minimum 25mpa and 100mm thick with F62 steel mesh halfway through the concrete. It should be screeded flat and level with no high or low spots. The finished surface should have a smooth troweled finish.
What are the types of reinforced concrete water tanks?
Conventionally reinforced concrete (RC) tanks have been used extensively in municipal and industrial facilities for water and wastewater treatment plants (WWTPs) for decades. There are three kinds of water tanks: on ground, underground, and elevated. The most commonly used at WWTPs is the underground tank.
What is minimum grade of concrete for design of water tank?
M30
Explanation: As per codal provisions of IS 3370: Minimum grade of concrete for the R.C.C water tank is M30.
How are concrete water tanks made?
Concrete rainwater tanks that are delivered in a complete form are craned off a truck and onto a prepared base of compacted crusher dust or compacted sand, stabilised around the edges. Pre-made concrete water tanks come in one to three pieces. A two piece tank is made up of two “cups”, one inverted on top of the other.
Do you need a concrete slab for water tank?
A concrete slab base is the most suitable base for your rainwater tank. Construction of a concrete base needs a minimum of 100mm thick concrete and F62 mesh, on a flat level area. Slabs must be large enough to support all edges of the tank, and should be at least 100mm longer and wider than the tank.
Where should water tank be placed?
The location of the tank should be towards the northeast direction of the Plot. Consider building your tank towards the north and east direction. When placed in the northeast, the tank can bring in happiness, wealth, and prosperity to your home.
How do you calculate water tank load?
Assume we need to calculate the size of a water tank for a residential building with 10 persons.
- Total Water Requirement = Number of persons X Minimum Water requirement = 10 X 135 Litres = 1350 Litres.
- We know, 1 m3 = 1000 litres of water.
- So the required storage volume for 1350 Litres = 1.35 Cubic Metre.
What is RCC water tank?
Reinforced concrete water tanks are constructed for storing water. The tanks can be made of reinforced concrete or even of steel. The overhead tanks (elevated tanks) are usually elevated from the rooftop through column.
What is the minimum grade of concrete?
The minimum grade of concrete used for RCC slab is M20 & M25. M20 concrete with ratio 1:1.5:3 means 1 part of cement, 1.5 part of fine aggregate (sand) and 3 part of coarse aggregate & M25 concrete with ratio 1:1:2 means 1 part of cement, 1 part of fine aggregate (sand) and 2 part of coarse aggregate.
Can you build over a concrete water tank?
Your tank can be constructed above or below ground, and its base needs to be flat – preferably laser-levelled, too.

Does a water tank need a foundation?
Water Tank Base: Why It’s Important Firstly, why is the base of the water tank important? A water tank filled to the maximum with water is extremely heavy. 1,000 litres of water is equivalent to 1 tonne. Thus, an appropriate foundation that can carry the weight of the tank when full is crucial.
What are the requirements for a reinforced concrete water tank?
The design of reinforced concrete water tank is based on IS 3370: 2009 (Parts I – IV). The design depends on the location of tanks, i.e. overhead, on ground or underground water tanks. The tanks can be made in different shapes usually circular and rectangular shapes are mostly used. The tanks can be made of reinforced concrete or even of steel.
What kind of concrete to use in a water tank?
The mix generally used for concrete works in water retaining structures is 1 : 1.5 : 3 (20mm). However for the floor concrete in these tanks 1:2:4 (20mm) concrete would suffice. This is possible as all internal facets of the tanks are being rendered and finished water tight using neat cement finish.
How to make a circular concrete tank work?
Design of Circular Concrete Tanks Introduction The goal of providing a structurally sound tank that will not leak is achieved by Providing proper reinforcement and distribution. Proper spacing and detailing of construction joints. Use of quality concrete placed using proper construction procedures. 3 Design of Circular Concrete Tanks
What kind of roof does a water tank need?
Internally, the tank can have several compartments for purpose of cleaning and maintenance. The roof can be reinforced concrete slabs or simply metal roofing. The walls are usually reinforced concrete, either tapered, staggered, or uniform thickness. The base is also reinforced slabs.

How much reinforcement is needed for a RCC water tank?
Minimum reinforcement for RCC water tank Minimum reinforcement required for 199mm thick sections is 0.3 % of the area of concrete section which reduced linearly to 0.2% for 450 mm thick sections.
What is a temporary joint in a concrete tank?
Temporary joint A temporary open joint is a gap temporarily left parts of a structure, which after a suitable interval and before the structure is put into use, is filled with mortar or concrete completely as shown in fig, or with the inclusion of suitable jointing material as illustrated in.
