IRR for 2009 ordinance approved; businesses told to install catchments
The city hall through Executive Order 45 released yesterday the Implementing Rules and Regulations of the Davao City Rainwater Ordinance of 2009.Councilor Leonardo Avila III, chair for the committee on environment, said the ordinance will focus primarily on business establishments to install rainwater catchments to save water coming from the tap for cleaning, flushing, and watering plants.

“We want to cut down the use of water coming from our aquifers, and utilize the rain since it is abundant and free,” said Avila.
In the IRR, the basic components of a rainwater catchment system include the collection system, conveyance, storage, treatment and disinfection system, and the drainage system.

The design will be promulgated, reviewed and approved by the City Building Official.

“Henceforth building designs will implement the rainwater catchment system,” said Avila.

According to Sect. 14 of the IRR, the rainwater catchment system will become a mandatory requirement for business establishments in the issuance of a new building permit.

Residential buildings and homes constructed prior to the ordinance are “encouraged” to install the system.

Businesses that fail to comply with the ordinance will be fined P1,000 but not more than P5,000, and imprisonment of not more than one year at the discretion of the court.

Avila added that for homeowners, a rainwater catchment system need not be a complicated structure as it can be as simple as collecting and storing rain for use in household chores.

“It is part of the Watershed Conservation efforts by the Watershed Management Council,” added the councilor.

The Rainwater Ordinance was crafted in 2002 and passed by the council in 2009.

Avila attributed the delay of the IRR to some additional meetings by the Watershed Management Council to fine-tune the provisions.
