Water containment modules for green and blue roof installations are disclosed. The modules include a water retaining module having a porous scaffold filled with a flexible hydrophilic foam, and a bottommost drainage layer having supports that define channels through which a fluid can flow away from the module. The module in some embodiment further includes an uppermost porous horticultural growth media layer that including a particulate filler embedded in a porous hydrophilic polymer foam.

Example implementations of a synthetic turf system comprise a turf tray and a turf element. The turf tray is rigid and planar, and has a lattice structure extending within the lateral perimeter. The turf element includes a backing portion and a blade portion. The blade portion is defined by a plurality of blades of artificial grass affixed to the backing portion, the backing portion is placed secured engagement with the upper side by way of, for example, adhesive or screws. The turf trays may include perimeter and auxiliary adhesive tracks, and an array of screw retention bosses. The system may include a sprinkler assembly mountable in the turf trays for washing down the turf elements. The sprinkler assembly may include mounting flanges configurable to accommodate mounting of various sprinklers. The system may include height-adjustable pedestals or joists to support the turf trays at a distance above the local horizonal surface.

A multi-functional tray that can be used in various applications to form different products, such as planter board for green roof plantation, thermal insulation structure for roof deck insulation, solid concrete panel for building construction, etc. The tray comprises an upper portion, a lower portion, and a backing layer connected between the upper portion and the lower portion. The lower portion comprises a plurality of reservoirs with through holes. The upper portion has a plurality of partitions and securing units to secure the material in the upper portion.

Contaminating material is extracted from a body of water by providing a floating bed on which plants such as Cat Tails can be grown with their roots hanging into the body of water over an area where extraction of contaminating material from the body of water is required, growing the plants to take up the contaminating material from the body of water and harvesting the upstanding plant mass by moving the bed to a harvesting machine which cuts away the plant mass leaving at least part of the root mass to continue growing into a new season. The bed can be returned to a location for the next season.

Plant surface structure, comprising plastic base elements, each base element having a deck carried by a series of pillar elements, wherein at least a number of the pillar elements have an open top end in said deck, wherein at least a membrane is placed over said deck and is provided with slits or cut-outs or water permeable elements, such that they open into at least some of the open top ends of pillars, wherein a growing medium is provided on the membrane and a growing medium is provided in said pillars, the growing medium in said pillars preferably being in fluid contact with the growing medium on said membrane.

A planter box for holding planting soil includes a box body having a bottom wall, a sidewall and an open top. An anti-clog drainage and irrigation pipe is mounted across and above the bottom wall. The pipe includes a water inflow and outflow opening formed at a lower portion and extending along the length of the pipe. Two flow-guiding plates extend from two longitudinal sides of the water inflow and outflow opening towards an interior of the pipe body to form two overflow troughs in the pipe. During rainy day, the pipe is used for drainage. During sunny days, water can be supplied to the pipe for irrigation. A method for soil drainage and irrigation is also disclosed.
