Collective housing and residential areas

For efficient management of water and wastewater resources in multi-family housing, it is essential to provide collective sanitation and rainwater harvesting solutions adapted to large capacities. Here’s an overview of the main options available to meet these needs.

All-water tank

The all-water tank is a traditional and widespread solution for collective sanitation. It treats both black water (from toilets) and grey water (from kitchens, bathrooms, etc.). Its operation is based on a decantation process that retains solids and enables wastewater to be pre-purified. In a collective context, it’s crucial to correctly size the tank and provide for a spreading system or compact filter to complete the treatment.

Grease separator

The grease separator is a complementary device to the all-water tank, particularly useful in large complexes where grease production is high, such as residences with several kitchens or catering facilities. It retains fats and oils, preventing them from accumulating and clogging the pipes, which is essential for maintaining a functioning collective sewage system.

Wastewater treatment plant

The wastewater treatment plant is a high-performance solution for treating wastewater in collective housing. Systems such as SIMOP’s BIOXYMOP MAX use aerobic biological treatment technologies for optimized degradation of organic matter. Although more complex than individual solutions, these systems offer superior treatment quality, are environmentally friendly, and can handle large quantities of wastewater with reduced maintenance.

Compact filter

For collective housing, compact filters like SIMOP’s Bionut solution, using recycled hazelnut shells as a natural filter medium, are particularly well suited. These systems, which require no electricity and can operate intermittently, offer an ecological and economical solution for domestic wastewater filtration. Their ability to handle large volumes of water makes them ideal for collective applications.

Rainwater harvesting tanks store water collected from building roofs for collective use (watering green spaces, washing vehicles, supplying toilets, etc.). For collective housing, it is necessary to use large-capacity tanks, which can be installed on the ground or buried, depending on requirements and site constraints. SIMOP offers a wide range of rainwater harvesting tanks adapted to large capacities, as well as filtration kits, pumps and rainwater managers for optimum ease of use.
