Sustainable drainage systems are an alternative to the traditional
approach of collecting stormwater.
Now is modular tanks momentum for rainwater harvesting
Urban Drainage Systems to ensure that flood risk.
Sekisui Cross‐wave system is complying to Qatar vision 2030.
Cross‐wave is a polypropylene based modular system for
underground rainwater harvesting systems assembled by
schematic stacking.
The technology of staged structure offers inbuilt stability and
security, while the module design ensures adequate water
infiltration along with storage.
Earlier constructed Rain water harvesting structures are not
practically working after few years of commissioning. Modular
Cross‐wave system overcomes all these shortcomings.
Our success is based on:
Support – Application based technical support
Trust – Famous Sekisui brand
Sustainability – Environmentally friendly solutions
Value – Smart, cost‐effective solutions
Applications:
Holding Tanks
Percolation – Infiltration Tanks
Recharge Tanks

5 sides infiltration
Seismic protection
Key benefits:
Space saving
Time saving
Low maintenance
Compact storage
Structural integrity
Environmental friendly
Accident free
Conventional RCC Civil Pit
Desilting Chamber with Jump walls cumbersome & costly cleaning
process
Pit size depth to provide for 1.0 mtr for air head for pressure, 1.5
mtrs for Filtration, effective holding volume nearly 25‐30%
50 CuM Pit = 20 CuM effective holding vol
Create RCC structure like a well time consuming construction
One direction percolation
Non load bearing surface
Conventional RCC Civil Pit
Accumulation of poisonous gases
Accident prone due to hollow structure
Desilting chamber does not perform the function properly
Cleaning the whole structure is tedious and expensive
Requires maintenance every year after three year of commissioning
Alteration is very challenging
Not possible to relocate
Because of no movement water quality reduces
Unskilled manpower is used and that reduces the quality of work
