separate foul and surface water sewers

Explanation:
The foul sewer is designed to carry contaminated wastewater to a sewage works for treatment, whereas the surface water sewer carries uncontaminated rainwater directly to a local river, stream or soakaway.

Kim Metzger: In the US we would call them separate wastewater and stormwater systems. /I worked on a water/wastewater training program for the US Army Corps of Engineers.

-> Thanks for the alternative version. Asker is in Brazil, so that may well be the preferred variant.

Johannes Gleim: This is not the term, but the description. // Please do not adopt suggestions without verifying on beforehand. Your first proposal was better, even it has less Ghits than my proposals. // No rephrasing, but research.

-> I'm not sure why you feel it necessary or appropriate to rephrase my answer after 24 hours have elapsed. You have missed out the vital information (foul and surface water) explaining the nature of these two systems (plural).

separate sewer system (separate seweage)

Explanation:
Beim Trennsystem (Trennverfahren) in der Entwässerungstechnik werden getrennte Leitungs- und Kanalsysteme für die Ableitung von Schmutzwasser und für Regen- und Fremdwasser angelegt. Bei Neubauten wird das Regenwasser von den Dachflächen getrennt von dem übrigen häuslichen Schmutzwasser gesammelt und oft in ein nahe gelegenes Gewässer geleitet.
https://de.m.wikipedia.org/wiki/Trennsystem

Sewage treatment is less effective when sanitary waste is diluted with stormwater, and combined sewer overflows occur when runoff from heavy rainfall or snowmelt exceeds hydraulic capacity of sewage treatment plants.[3] To overcome these disadvantages, some cities built separate sanitary sewers to collect only municipal wastewater and exclude stormwater runoff collected in separate storm drains. The decision between a combined sewer system or two separate systems is mainly based on need for sewage treatment and cost of providing treatment during heavy rain events. Many cities with combined sewer systems built prior to sewage treatment have not replaced those sewer systems.[4]
https://en.m.wikipedia.org/wiki/Sanitary_sewer

Separate sewerage consists in the separate collection of municipal wastewaters (blackwater from toilets, greywater and industrial wastewater) and surface run-off (rainwater and stormwater). The separate collection prevent the overflow of sewer systems and treatment stations during rainy periods and the mixing of the relatively little polluted surface run-off with chemical and microbial pollutants from the municipal wastewater. The design of the sewers and the (semi-)centralised treatment stations thus needs to consider the volume of the wastewater only and the surface run-off and rainwater can be reused (e.g. for landscaping or agriculture) after a simplified treatment.
http://www.sswm.info/content/separate-sewers

A separate sewer system consists of two different sewer pipes running one on top of the other, or “piggyback.” In most instances, the sanitary pipe is below the storm pipe. The sanitary sewer pipe transports sanitary sewage collected from the laterals (plumbing connections) of homes, businesses, and industry to treatment plants. The stormwater sewer pipe carries water collected from street inlets, building downspouts, and other storm sewer lines to a nearby receiving stream and is discharged through a Stormwater Outfall.

Abstract
This paper aims at comparing the cost-effectiveness of the two main types of urban drainage systems, that is, the combined sewer system and the separate sewer system, based on the analysis of simulations.

This answer is valid for sewer systems, but not for water supply (separation between potable water and industrial water systems).

Der Begriff „Trennwassersystem“ ist sehr selten. Üblicherweise spricht man von Trennsysteme. Nachfolgend weiter Links:

Trennkanalisation - Trennsystem
(separate sewer system, separate sewer)
Bei der Trennkanalisation wird das Schwarzwasser getrennt vom Regenwasser in zwei Kanälen abgeleitet. Der Vorteil einer Trennkanalisation ist die Entlastung der angeschlossenen Kläranlage und des Vorfluters.
http://www.wasser-wissen.de/abwasserlexikon/t/trennkanalisat...

… Besser wäre es, wie im englischsprachigen Raum auch den Begriff Mischwasserüberlauf (Combined Sewer Overflow) zu verwenden.

Von diesen Mischwasserüberläufen, mit denen unbehandeltes Mischwasser direkt in die Gewässer eingeleitet wird, geht eine nicht unerhebliche Gewässerbelastung aus. Zum einen werden die Gewässer hydraulisch und stoßartig mit sauerstoffzehrenden Schadstoffen belastet. Im Vergleich zu Regenwassereinleitungen aus dem Trennsystem werden durch Mischwasserüberläufe vermehrt Sauerstoff zehrende Stoffe eingetragen.
http://www.sieker.de/de/fachinformationen/umgang-mit-regenwa...

Um diese Vorgaben umzusetzen sollten die Abwässer möglichst rasch und sicher aus dem Siedlungsgebiet abgeleitet und einer Abwasserreinigung zugeführt werden. Dazu können generell zwei unterschiedliche Transportsysteme angewandt werden:
• Trennsystem (separate sewer system)
mit getrennter Ableitung von Regen- und Schmutzwasser in unterschiedlichen Kanalsystemen.
• Mischsystem (combined sewer system)
mit Ableitung von Regen- und Schmutzwasser im selben Kanalsystem
