A sump is a below ground chamber that provides access to tank system components and, when contained, prevents liquids from releasing into the environment.
Sump size should be directly proportional to the number of houses you are constructing in site and water availability. If there is only one house then 6000 liters to 8000 liters sump is sufficient. Constructing rented houses then maintain more storage space for sump (12000 ltrs of water).
Having bigger tank is useful when there is a water scarcity.
- Water pressure will be more on the edges of the tank. So avoid constructing sump/tank corners with 90 degrees like room walls.
- When you are constructing sump, have edges in a curved shape. So that water pressure will be diverted to a larger area. This will have some significant effect in the long run.
- While constructing sump, Manson will use iron mesh during plastering to avoid cracks.
- Sump and tank plastering should be completed at one stretch to avoid cracks.
- Do not use low quality brick for sumps and tanks.
- Keep sump door always towards street side. So that tankers can pour water easily.
- Keep 3″ pipe connection to the sump from outside. So that water tankers can directly pour water from outside.
