Differences between PP rainwater tanks and concrete tank

0 Comment

The differences between PP rainwater tanks and concrete reservoir are mainly manifested in 7 aspects:material, service life, transportation, construction, duration, cost, environmental protection.

Differences between PP rainwater tanks and concrete tank

Disadvantages of concrete tank
1. The construction process is complex, the process is more (formwork, tied steel bars, the pouring, the maintenance, etc.), the construction period is long.And the construction is affected by the season and weather.
2. Due to the requirements of structure and construction process, the conditions of the construction site are required.
3. Low load on the tank surface, which cannot be used twice.
4.heavy weight,easy to produce uneven settlement.
5.Poor crack resistance, easy to produce leakage.
6.Once the concrete structure is damaged, it is difficult to repair and reinforce concrete structure.
7.The material can not be recycled after being abandoned, causing secondary pollution to the environment.

Advantages of PP rainwater harvesting tank

1.Flexible design:It is designed with standard modules and can be designed into various irregular shapes and sizes according to the project.
2.Large capacity:95% hollow space and large storage space.
3.Fast installation:Able to assemble quickly without tools, drastically reducing workload.
4.Easy construction:Reduce 30% of excavation and transportation,and 60% backfill volume.
5.Short periods:It can be backfilled on the same day of excavation.
6.Save space:PP rainwater tank modules can be installed underground,they won’t occupy overground space,nor influence landscape effects as well.
7.Clean water:The rainwater enters the underground water tank then discards and filter impurities.It has enough aerobic activity space in the module.
